Abstract

A retaining valve pneumothorax exhaust pipe relates to an exhaust pipe exhausting gas in the thorax. A partition board is arranged in the exhaust pipe and divides the exhaust pipe into two air ducts which respectively pass through a pricker and connect with an inlet pipe, an air cell is respectively connected with an upper retaining valve and a lower retaining valve up and down, the upper retaining valve is connected with a gas outlet externally, the lower retaining valve is connected with the inlet pipe connected with the air duct of the exhaust pipe, the exhaust pipe is provided with a positioning ridge, and the duct opening of the air duct passing through the pricker is provided with an adjusting card. When the retaining valve pneumothorax exhaust pipe is used, the metal pricker is inserted into the duct of the exhaust pipe with the adjusting card, the exhaust pipe is placed and fixed, the air cell is extruded, gas in the thorax is sucked in the air cell through the air ducts and the inlet pipe and is discharged through the upper retaining valve and the exhaust outlet. The utility model has simple, reasonable and scientific structure, convenient installation, easy operation and good control effect, can quickly discharge the gas in the thorax, releases the breathing difficulty, keeps normal thorax pressure, maintains normal breathing, has light pain when in use, and can be moved without accompanying by family.

Description

Check valve pneumothorax exhaustor

Technical field

This utility model relates to a kind of exhaustor of discharging gas in the thoracic cavity.

Background technology

Closed pneumothorax is a clinical common emergency case.Cardinal symptom is the dyspnea that causes after lung is compressed, normal threat to life.The main means of Clinical Processing are to discharge intrathoracic gas, and lung is opened again, remove symptoms such as dyspnea.But conventional traditional closed drainage needs in particular environment, and the regular hour prepares, and than the masterful technique operation, and because of drainage tube is thick, water-sealed drainage bottle is arranged, and also can cause more violent pain and inconvenient activity to patient, also needs accompanying and attending to of household.Coming off of drainage tube can cause open pneumothorax, mediastinal flutter, threat to life.

Existing " kink crack valve-type drainage tube " (Chinese patent application 91213143), form by concentric tube conduit and the external fixation medicated cap made with PVC series medical plastic, the outer tube of concentric tube conduit is about 15cm, at the distance outer tube and near the breast end be have on the tube wall outside the 0.5cm three vertical, parallel, etc. arc distance, isometric crack, outer tube near chest and diaphragm links to each other with inner tubal wall, the external diameter that has ceasma, aperture to be slightly less than drainage tube that the external fixation medicated cap is less.

Summary of the invention

The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of simple in structure, scientific and reasonable, easy for installation, processing ease, control is effective, pain is light, can discharge the check valve pneumothorax exhaustor of gas in the thoracic cavity rapidly.

The implementation of this utility model purpose is, check valve pneumothorax exhaustor, partition is arranged in the exhaustor, partition is separated into exhaustor and connects two airways that pass the puncture awl and tap into trachea, the upper and lower check valve of the upper and lower tap of air bag, and two check valve directions are in the same way, the external air vent of last check valve, following check valve connects the air inlet pipe with the exhaustor airway, and exhaustor has the location bank, and the road junction of passing puncture awl airway is provided with regulates card.

When using this utility model, the metal puncture awl is inserted the passage that the aerofluxus pipe racks is regulated card, exhaustor is placed between pneumothorax side second rib, fix with location bank, fixing band on the pipe, withdraw from metal puncture awl, close the scalable card when withdrawing from and join with spiral outer medicated cap.With hands extruding gasbag 3, intrathoracic gas by airway, air inlet pipe inspiration air bag, is discharged by last check valve, air vent.

This utility model is simple in structure, scientific and reasonable, and easy for installation, processing ease, control are effective, can discharge gas in the thoracic cavity rapidly, alleviate dyspnea, keep normal pleural pressure, keep eupnea; During use, pain is light, and is movable, do not need the household to accompany and attend to.

The specific embodiment

With reference to Fig. 1, have in the exhaustor 13 and cut off 14, partition 14 is separated into exhaustor and connects two

airways

12,10 of passing puncture awl 8 and trachea 5.The road junction of passing the puncture awl airway 10 of drainage tube is provided with regulates card 9, and the road junction of the airway 12 of trachea 5 is equipped with check valve 11, and the direction of check valve 11 is outside, and has a spiral interface and external spiral interface 6 to join.The direction of check valve 11 is outside, should make gas from inside to outside, so that enter air intake duct 5.

With reference to Fig. 2, upper and

lower check valve

2,4, the two check valve directions of air bag 3 upper and lower taps in the same way.Last check valve 2 external air vents 1, following check valve 4 connects the air intake duct 5 with the exhaustor airway, and exhaustor 13 has location bank 16.Air intake duct 5 has check valve 11 with the air bag seam, with the seam of airway external spiral interface 6 is arranged.

Last check valve 2 spool smooth surfaces tightly contact with check valve air inlet side inwall, and matsurface is hemispherical grain, and matsurface and check valve are given vent to anger the gap of discharging gas between the side inwall.

When using this utility model, metal puncture awl 15 is inserted the passage that the aerofluxus pipe racks is regulated card, exhaustor is placed between intrathoracic pneumothorax side second rib by the metal puncture awl, is fixed on the thoracic wall with the location bank on the pipe, fixing band 16.Fixing band can be gauze and adhesive sticker.

Withdraw from metal puncture awl, close scalable card 9 when withdrawing from and join with spiral outer medicated cap 8.The external spiral interface 6 of the air inlet pipe 5 of air bag 3 spiral interface with check valve 11 is joined, and air inlet pipe 5 is joined with airway 12.During extruding gasbag 3, gap and air vent 1 that gas is given vent to anger between the side inwall from the matsurface and the check valve of check valve are discharged.Unclamp air bag, the air bag elastic recoil, the valve core adverse movement of two check valves, intrathoracic gas enters in the manual air bag.Extruding is discharged again, carries out so repeatedly, and is normal until intrathoracic pressure.

This utility model is easy to use in order to make, health, safe and reliable, needs to adopt disposable airtight package, and sterilization is opened during use again.
