Description

But disposable oxygen supply semi open model reservoir bag

Technical field:

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of multi-functional, disposable respiratory ventilation system and device.

Background technology:

Having that use is more general in the existing anaesthesia breathing system (claiming anaesthetic circuit again) is following several: (1) closed-circuit anesthesia method, (2) hemicompact are closed method (or claiming semi-open method), and (3) do not have the inhalation of repetition.

The closed-circuit anesthesia method: advantage is more, but is mainly used in the clinical anesthesia process, is equipped on the anesthetic machine.

The closed-circuit anesthesia method can reuse very through flowing effectively because of oxygen and anesthetic gases, and fresh gas flow need not the humidifying of heating, and mechanical dead space is minimum, and the anesthesia depth is easy to control, can pass through reservoir bag perception patient ventilating situation, can be used as low discharge suction general anesthesia.But the guiding flap valve is arranged in this system, and soda lime jar and breathing tube device have produced certain mechanical resistance thus, and the outmoded more resistance of device is big more, especially more serious to children's's influence, so limited its scope of application.In addition, because the volumetrical cushioning effect of this internal system, gas concentration does not often conform to fresh gas flow in the suction gas, when doing low discharge suction general anesthesia, exist fraction of inspired oxygen to cross low and the dark partially shallow partially danger of general anesthesia, must have accurately oxymeter face in the anesthesia and protect with suction anesthetis concentration determination instrument.

Method is closed in hemicompact: main use Maxwell D type etc. arranged, this device is simpler, is the respiratory ventilation device of disengaging anesthetic machine, and is easy to use.Be mainly used in children operation anesthesia clinically.

As shown in Figure 1, the reservoir bag 11 on it connects endotracheal tube by corrugated tubing 13 (length is greater than 1 meter), and is provided with an air bleeding valve 12 on corrugated tubing far-end coupling part, is provided with an oxygen supply angle coupling 14 on corrugated tubing near-end coupling part.This device is because reservoir bag is to be connected with endotracheal tube by corrugated tubing and angle coupling thereof, this just makes the direction in whole air bag and loop fix, can not change along with the change of the patient posture of reviving gradually (or head position), thus cause endotracheal tube discounting (can not ventilate), lead drag and medical personnel's treatment operation constant; And the oxygen supply joint on it, very inconvenient when attended operation.

Do not have the inhalation of repetition: this system has dead space and the little characteristics of respiratory resistance, is particularly useful for the anesthesia of infant and breathes management.

Because of making the assimilation of alveolar gas and fresh gas flow rapidly, be specially adapted to anaesthetize preceding denitrification again, induction of anesthesia is deepened or is subtracted shallow and occasions such as anesthetic gases discharge are quickened in anesthesia when finishing.But the necessary adjacent patient respiration road of the flap valve in this system, this causes operation inconvenience, and after long-time the use, the dampness in the expiration, secretions, blood etc. can make flap valve malfunctioning, the danger of generation anoxia and carbon dioxide accumulation.

The utility model content:

This utility model is at the existing various drawbacks of above-mentioned existing various respiratory ventilation systems, and revive, the different respiratory therapy requirements in short time recovery transition period, and provide a kind of and revive, required control breathing of recovery transition period, help breathing, autonomous respiration observation, autonomous respiration oxygen therapy etc. and integrate multiple treatment function, simple and effective, disposable respiratory ventilation system and device.

In order to achieve the above object, the technical solution adopted in the utility model:

But disposable oxygen supply semi open model reservoir bag comprises oxygen supply joint, open straight joint and reservoir bag three parts; Described reservoir bag is connected with the oxygen supply joint by open straight joint, and also can be the dismounting connection between three parts.

Described open straight joint is that transparent materials such as medical rigid plastics are made, and is provided with the straight joint of a circular open that communicates with atmosphere on body; This circular open is provided with a control valve, and open section tube chamber appropriateness caves in, and this degree of caving in is not more than 1/2 of tube chamber.

Described oxygen supply joint is made with medical high polymer equally, scalable and folding break-in, and this joint near-end does not influence with the endotracheal tube junction and is provided with an oxygen supply conduit.

The oval soft sacculus of described reservoir bag for adopting synthetic rubber or plastics to make.

This utility model that obtains according to technique scheme integrates multiple treatment functions such as control breathing, assisted respiartion, autonomous respiration observation, autonomous respiration oxygen therapy, and has the following advantages: 1. respiratory resistance reduces greatly; 2. fraction of inspired oxygen height; 3. has air flue protection (moisture-heat preservation) effect; 4. has the respiratory resuscitation effect; 5. reservoir bag can be done anesthesia (machine) reservoir bag earlier, does the reservoir bag of reviving again, and a capsule is dual-purpose, and is simple and effective, economical and practical.

This utility model has solved in the postoperative recovery from anesthesia process, and the patient respiration function grows out of nothing, by weak crescendo, until the difference treatment demand near normal this dynamic change, has more cut off the reservoir bag link of nosocomial infection.
