It's good to have an idea, but it doesn't depend on the doctor himself, but on another group of people who have suffered a huge blow during this time.

After reporting to the Duke on the progress of the work for the past two weeks, Kraft took a loaf of bread from his lunch plate and hurried to the workshop to check on the work of the craftsmen.

The jeweler, who was not very good-looking, showed him something unexpected.

"How is this done?" Craft carefully pinched the thin silver tube in the velvet cushion with two fingers, and looked at the light.

The light through the middle shows that it is indeed a hollow tube, with a thin and uniform wall, a sharp end, and a polished surface. The few traces of hammer forging that remain suggest that it may have been machined from beaten silver sheets.

He thought he would never see something so delicate in his life. Brush shoulders with the terrible fate of making needles out of feathers or fine bones. Although this thing has too high requirements for the diameter of the patient's blood vessels to make a syringe, it is barely up to the standard of thoracenthalic needle.

The only worry is the strength of the material, and if it is bent, it is good to say, but if it is broken, it is the real big trouble.

The needle is attached to a wooden bolt that matches the connecting tube required by Kraft. They made the tube out of rolled thin leather, treated with some kind of adhesive on the overlapping surface, and the texture is tough compared to the rubber tube, which is difficult to bend, but the air tightness is trustworthy.

"Will this glue melt away?"

"You can even use it to spit bubbles underwater."

The craftsman's assurance gave Kraft a lot of peace of mind, and he couldn't imagine what it would be like for the tube to fall apart halfway through the operation.

As for the gas storage device, it is simply simplified to a large skin bag, anyway, the volume of the lung and thoracic cavity is not a few liters, and it is difficult to make a special toss a multi-component pump, and it is difficult to ensure the sealing ability. It's just that this is a bit of a test of the operator's technique.

These things can basically meet the minimum requirements of the Kraft operation, and under the condition of a controllable degree, a pneumothorax state is artificially created.

The specific operation steps are not complicated, and they are basically reversed on the basis of thoracentesis.

He needed to pierce the duke's chest wall with this needle, which was attached to the skin tube, and penetrate the layer of pleura that was attached to the ribcage of the chest, reaching the middle of the two pleuras. Then the next step is to put the qi in and "flatten" the lungs by air pressure.

This process will not be achieved overnight, and scoring a few injections also means that the patient will receive a few more injections. The experience without anesthesia was not much better, to put it mildly, but since the Duke had survived the enema and bloodletting, it was reasonable to place some trust in his tolerance.

Looking back now, the original plan was basically in line with current needs. Under the elevated air pressure, the lungs will be gradually compressed, and the cavities in the lungs will shrink and close at the same time, leaving less and less room for the bacterium to live comfortably, until it voluntarily abandons this deteriorating dwelling.

Theoretically, yes.

But this brings with it another question: how will it move?

Ideally, the mycelium ball will operate the main host mycelial ball, from the tuberculosis cavity into the bronchi, the main bronchus, and all the way up into the trachea. Then it crawls through the longest stretch of the trachea, which is probably not too short.

It is best to ensure that the airway is open and not blocked by the dilated hyphae. As it happens, there is something that can be used in the current achievement.

"The leather tube is very well done, make another one, and add a few metal rings to support it, it is harder, but not too hard." Tenacity also has the benefit of tenacity, which is just used for endotracheal intubation.

"Huh?"

……

……

"Your Excellency, before everything begins, I must inform you of the purpose of this operation and the risks."

"As mentioned earlier, this is a treatment to temporarily relieve your lung symptoms, but it doesn't completely cure the disease, and it doesn't even necessarily make you feel better." Kraft unravels the instrument bag layer by layer and wipes it with high-strength wine.

The package ticket that the craftsman gave him did not include that the boiling water could be used after disinfection, and in the end it had to be wiped manually, and the effect would be worse. The rich, almost pungent smell of alcohol escapes through the room.

The Duke closed his eyes and bowed his head to indicate that he was listening, and his expression was much more relaxed than that of the doctor, like an unrelated bystander, "This smell reminds me of when I was young, and I had to quit when I had lung disease. ”

No, that's unlikely, I'm afraid I won't get lung disease by drinking such wine. Craft sneered.

"After the beginning, there is a probability that some conditions that are not subject to subjective control will occur, such as exuding fluid, fever does not go away, chest pain is aggravated, dyspnea, etc., subcutaneous emphysema may occur in the short term, and in severe cases, it may injure blood vessels, resulting in life-threatening vascular embolism."

In fact, the probability is not large, the puncture and qi injection will be carried out under the guidance of the spiritual senses, but the notification process must be reached.

Hearing the last one, the old duke's eyelids raised slightly, "I take the liberty of asking, have there been any patients who have been frightened away by this set before?" ”

"It's not just a fabrication, it's a real risk."

"If you're lucky or unfortunate enough to go to war in the future, remember not to talk like that to your soldiers." As requested, he lay down on his left side, lifted his robe, and exposed the right side of his chest where the treatment was to be performed, "The Duke of Westminster has agreed to the treatment, and you may begin, Dr. Kraft." ”

"Thank you for your trust."

Fingers from top to bottom, count to the eighth intercostal space, extend to the side to the axilla, select the needle insertion point at the upper edge of the rib, and avoid the neurovascular vessels running along the lower costal groove as much as possible.

A cold mass sticks to the skin.

"Please relax, now it's just a matter of cleaning up your skin." The cotton ball dipped in alcohol is centered on the puncture point, and the area is expanded one by one, and you can feel a large circle of chill appear on your back.

"Now, it's up to you to be patient and reduce your activities as much as possible." Kraft spread out the towel and took out the puncture needle connected to the tube, which was temporarily clamped and sealed with small pliers, "I recommend having the guards hold you down, otherwise it may cause unnecessary damage." ”

Of course, this suggestion was not adopted either.

After confirming that the preparation is complete, he connects the mental senses, fixes the skin at the puncture point, and holds the needle against it for a few seconds to ensure that the patient is mentally prepared, and then begins to insert the needle.

Standing on the back side, the Duke's expression could not be seen, but he could clearly feel the change of his body from relaxed to straight as the tip of the needle pierced the epidermis, the muscles contracted and bulged, and his breathing stagnated.

Except for the slight creak of his clenched teeth rubbing, all he could hear was his heartbeat.

The spirit "sees" how the metal penetrates through the subcutaneous tissue, easily pokes a slippery path in the not thick fat layer, pierces the tense muscles, and after receiving a little block, continues to break through the chest wall, the intercostal muscles, and refrains through a membrane attached to the rib cage.

The feeling of frustration was synchronously fed back to his hand, indicating that he had successfully entered the pleural cavity, and the tip of the needle was now resting in front of the lung, less than three fingers away from the cavity where the bacterium resided.

The fungal spheres cling to the cavernous walls of necrotic hyperplasia and granulation with silk legs, and are as safe as a vole hibernating in its nest, unaware of what is happening.

Docking the tube with the balloon mouth, Kraft tried to loosen the clamp so that the air flowed into the pleural space as evenly and slowly as possible, "You can continue to breathe, Your Excellency." ”

As the rhythm of breathing fluctuates, gases that are less noticeable than the amount of intake and outflow are mixed into the process, and the expansion of the lungs begins to be limited.

At present, the form is not obvious, and if you can take a chest radiograph here, it will probably appear as a narrow peripheral dark band that needs to be magnified to find, which is very indistinguishable from the lung field, and the subtle texture of the lung terminates at the translucent boundary before the dark area.

With each short injection of gas, Kraft pauses for two breathing intervals to assess compression and bacterium status.

Probably because of the habit of periodic changes in air pressure and airflow in the lungs, it seems that this thing is far less sensitive to pressure changes than other stimuli. It did not respond agitated until it was injected close to half the amount of the duke's calm breath in and out.

At this time, the compression has begun to bear fruit, and there is a difference between the expansion of elastic lung tissue and the scar lesion tissue during inhalation, which has an initial compression effect on the cavity. I vaguely felt the velvet commotion of the fungus ball that had reduced the activity space, and it seemed that it was about to wake up.

Kraft stopped the gas injection in time, withdrew the syringe, and pressed the puncture point with a cotton dressing, ending the first gas injection.

"Your Excellency, please lie down and rest for a while, at least I don't want to see you show extraordinary courage before the next meal."
