Description

Tracheal humidification pump

technical field

The utility model relates to the field of medical supplies, in particular to a tracheal humidification pump.

Background technique

In patients with tracheotomy, the upper airway is replaced by a catheter, which destroys the normal anatomical structure and physiological functions of the airway, loses the functions of heating, humidifying, filtering and coughing of the upper airway, and weakens the defense ability. If the humidification of the airway is not enough, it is easy to cause water loss in the lower respiratory tract, dry airway, inhibition or loss of ciliary movement, secretions become sticky, easy to form phlegm scab or blood scab, resulting in poor expectoration, Tracheal blockage and hypoxia can cause atelectasis and secondary lower respiratory tract infection, which can even be life-threatening in severe cases.

At present, airway humidification methods mainly include intermittent bolus humidification method, continuous infusion method of infusion tube, continuous humidification method of syringe pump, artificial nose, atomized humidification, etc. The intermittent bolus humidification method is simple and convenient to operate, but it cannot meet the continuous humidification requirements of the artificial airway. The amount of humidification fluid injected into the endotracheal tube each time is large, and the speed is difficult to control, which can easily cause irritating coughing, rapid heart rate, When the blood oxygen saturation drops, the humidification fluid can be coughed up, affecting the humidification effect. For awake patients, fear and anxiety will increase. The continuous infusion method of the infusion tube and the continuous humidification method of the syringe pump meet the requirements of continuous humidification of the human airway, without causing choking or irritating cough, and can keep the artificial airway in a good continuous humidification state, with sufficient humidification and reduced phlegm The viscosity of the liquid is not easy to form sputum, and it is easy to exclude respiratory secretions; it has the advantages of ensuring the total amount of humidifying liquid and the speed of injection. However, these two methods all need to be completed under the operation of medical staff, and the patient's activities are restricted, which is not suitable for patients who are awake and can move independently. The artificial nose, also known as the temperature-humidity exchange filter, is a light and soft connecting tube that can simulate the function of the nose, warm and humidify the inhaled gas, and ensure effective and proper humidification of the airway. However, they are expensive, need to be replaced every day or at any time, and cannot be used for those wearing metal tracheal tubes. Atomization humidification is an intermittent humidification method. Its airway humidification effect is better, but it cannot achieve the effect of continuous humidification. It needs to be carried out by an atomization machine, which is limited by the site.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

In order to provide a tracheal humidification pump that is cheap, portable, easy to operate, and capable of adjusting the flow rate, the tracheal humidification pump includes a liquid storage bag 4, a protective shell 1 and an infusion tube 9, and a cavity 2 is formed inside the protective shell 1. , the liquid storage bag 4 is located in the cavity 2, the infusion tube 9 is connected to the liquid storage bag 4, the tracheal humidification pump also includes an inflator 5, the protective shell 1 is a sealed structure, and the inflator 5 communicates with the cavity 2.

The utility model uses the principle of an infusion pump (analgesic pump) for reference. The infusion pump is a device for injecting analgesic medicine into the patient's blood to relieve the patient's postoperative pain. Injecting analgesic medicine into the patient's blood is very similar to injecting humidification medicine into the patient's trachea, and the flow per unit time of the medicine is also similar, so the utility model can learn from the principle of the infusion pump. The infusion pump mainly includes a liquid storage bag 4, a protective shell 1 and an infusion tube 9, the infusion tube 9 is connected to the liquid storage bag 4, and the infusion tube 9 is provided with a liquid filling port 6 for adding medicine to the liquid storage bag, a stop medicine Liquid flow stop card 7 and additional medicament device. The liquid storage bag 4 is made of silica gel and is elastic, and through the elasticity of the liquid storage bag 4, the medicine is slowly pumped out of the liquid storage bag 4 and injected into the patient's body through the infusion tube 9. The existing infusion pump does not have a device for adjusting the flow rate, and the conventional flow rate is a constant value. When additional medicaments are needed, it needs to be added by an additional medicament device. The utility model is equipped with an inflatable device 5, through which the air pressure in the cavity 2 can be changed, thereby changing the pressure on the surface of the liquid storage bag 4, and then changing the pressure of the medicine in the liquid storage bag 4 so that the flow rate of the medicine can be changed to adapt to different conditions. The needs of the patient and the extent of the condition. The utility model does not need to be provided with an additional drug device, and its structure is not more complicated than that of an analgesic pump; compared with the existing airway humidification device, the utility model has low cost and can be carried around.

The inflation device can have multiple settings, such as automatic inflation with a miniature air pump. The utility model does not need to be inflated frequently; the volume of the cavity 2 is not large, and the amount of inflation is not large; the inflation pressure does not need to be very high; therefore, the utility model is recommended to be set as follows: the inflation device 5 is an airbag. The air bag is often used in medical supplies such as tracheotomy intubation, anesthesia intubation, urinary catheter, etc. It has low cost, good inflation effect, and can be inflated and deflated. Clinically, a syringe is used to inject air or water into the balloon to achieve fixation and hemostasis. The trachea humidification pump of the utility model uses a syringe to inflate/deflate the air bag to increase/decrease the air pressure of the chamber 2 to adjust the flow rate of the humidification liquid.

Inflator 5 also can not borrow existing air bag and self-design. The principle of the inflatable device 5 can be shown in Figure 2: the inflatable device includes a rubber air bag 14, and a check valve 13 is respectively arranged on the side of the rubber air bag, and the rubber air bag 14 is connected with the cavity 2, and on the pipeline between the rubber air bag 14 and the cavity 2 Air vent 12 is set. Kneading the rubber airbag 14 can inflate to increase the flow rate of the humidification solution; if the inflation is excessive, open the air port to deflate to reduce the flow rate of the humidification solution. The infusion rate of tracheal humidification is generally about 4-6mlml/h, which is very slow. Therefore, it is not necessary to inflate to adjust the flow rate of the humidification solution for a long time after the gas is inflated to adjust the flow rate of the humidification solution. Therefore, it is recommended that the inflator 5 be detachably connected to the protective shell 1 in the setting method of the inflator 5 . When not inflating, the inflation device 5 is removed, which saves the volume and weight of the whole device, and facilitates the placement of the protective shell 1 and the liquid storage bag. In the setting method in which the inflation device 5 of the last section is an airbag, the airbag is very small and difficult to disassemble.

In order for the patient to intuitively understand the flow rate of the humidifying fluid and to facilitate the adjustment of the humidifying fluid flow rate, the tracheal humidification pump includes a flow display device 3 that converts the pressure signal into a flow signal display, and the flow display device 3 is connected to the cavity 2 . The flow display device 3 should include a pressure measuring device and a display screen. The flow rate of the humidifying fluid corresponding to the air pressure can be obtained through theoretical calculation or experimentation, and the flow rate of the humidifying fluid can be displayed on the display screen through data conversion.

In order to facilitate the placement of the protective shell 1 and the liquid storage bag 4, the general length of the transfusion tube 9 is longer. If the protective shell 1 and the liquid storage bag 4 are placed farther away from the nose when the patient carries the utility model, then the transfusion tube seems very cumbersome. In order to facilitate the placement of the infusion tube 9, the tracheal humidification pump includes a fixed card 8, which is connected to the infusion tube 9. The infusion tube 9 can be surrounded in a circle or around the neck, and the circle formed by the fixed clip 8 can be fixed. The fixed card 8 can be a hook and loop.

The infusion tube 9 can be inserted into the trachea during infusion, but after being used once like this, the infusion tube 9 is polluted by sputum etc., and it is difficult to reuse and cause waste. In order to save the use cost, the tracheal humidification pump includes an extended infusion tube 10, and one end of the extended infusion tube 10 is connected to the end of the infusion tube 9. When using like this, the extension infusion tube 10 is inserted into the trachea, and the extension infusion tube 10 is replaced when used next time, and the extension infusion tube 10 can be shorter and can save the use cost.

In order to fix the protective shell 1 and the liquid storage bag 4 conveniently, the end of the protective shell 1 is connected with a protective shell fixing clip 11 .

The operating steps of this tracheal humidification pump are as follows:

a. Clamp the infusion tube 9 with the flow stop card 7 (do not clamp the section from the liquid filling port 6 to the liquid storage bag);

b. Use a syringe to inject an appropriate amount of humidification liquid into the liquid storage bag 4 through the liquid filling port 6;

c. Inflate to adjust the infusion speed, and remove the inflatable device 5 after adjustment;

d. Insert the extended infusion tube 10 into the patient's tracheal tube (into about 5cm);

e, fixing the infusion tube 9 and extending the infusion tube 10;

f. Place the protective case 1 properly.

It can be seen from the above steps that the tracheal humidification pump is easy to operate. In addition to being used for tracheal humidification, the utility model can be used to replace infusion pumps, and can also be used in other places where slow infusion is required.
