Abstract
The utility model discloses a medical treatment using oxygen therapy device, which comprises a mask and an oxygen therapy pipe. The mask is connected with a gas storing tube on the upside. A gas inlet check valve through which the air enters is arranged on the top of the gas storing tube. A gas outlet check valve by which the waste gas is exhausted is arranged on the mask. The utility model provides enough air and exhausts the waste gas in time, the oxygen utilizing rate is high, and the oxygen therapy effect is good, thus the treating effect can be greatly improved and the using oxygen can be saved.
Description
Technical field
This utility model belongs to medical treatment oxygen therapy utensil class
Background technology
The utensil that is used for medical treatment oxygen therapy at present will have been calculated oxygen therapy cover than advanced, and it is formed by face shield with the oxygen catheter that oxygen is directly imported in the face shield.Its air enter and exhaust gas discharging is all undertaken by the gap between face shield and the patient's face, cause waste for preventing that oxygen from too much running out of, and it is unfavorable to curative effect, above-mentioned gap can not be excessive, so entering and also difficulty relatively of the discharge of waste gas of air often makes patient that the sensation of hypopnea is arranged.
The utility model content:
Discharge the deficiency of difficulty in order to overcome the air admission and the waste gas that exist in the prior art, this utility model provides a kind of can provide enough air and timely combustion gas, and the oxygen utilization rate height is cured by oxygen therapy effective oxygen therapy device.
This utility model comprises face shield, oxygen catheter, and face shield top is communicated with a gas receiver, and the top of gas receiver is provided with and allows the breather check valve of air admission, and face shield is provided with the exhaust check valve that allows waste gas get rid of.
Breather check valve is formed by vavle shelf with the diaphragm seal that vavle shelf is complementary, and vavle shelf is connected with diaphragm seal by its middle position, and diaphragm seal is adsorbed on the vavle shelf in gas receiver, and vavle shelf is sealed; The identical installation direction with the breather check valve structure of exhaust check valve is opposite
Be provided with a hole that is used for inserting stomach tube on the face shield.
Because having increased by one on the face shield of existing oxygen therapy cover, this utility model is attached thereto logical gas receiver, a breather check valve is arranged at the gas receiver top, also be provided with an exhaust check valve on the face shield, when oxygen catheter is sent into oxygen in the gas receiver, breather check valve is closed, oxygen is stored in the gas receiver, when patient inhales, check valve is opened, air enters in the gas receiver by check valve and is inhaled into the human lung together with oxygen, exhaust check valve on the face shield is closed at this moment, and oxygen can not be run out of from exhaust check valve; When patient exhales, exhaust check valve is opened, and waste gas is discharged thus, simultaneously because waste gas mainly is CO
2, it is heavier than oxygen, so oxygen can be run out of from exhaust check valve hardly thereupon.Therefore this utility model can provide enough air to satisfy the needs of vital capacity, and can guarantee that the oxygen more than 95% enters human body, cure by oxygen therapy effective, improved curative effect greatly, oxygen is fully used, user is not had the sense of dyspneic discomfort again, secondly inserts the stomach tube hole because this utility model is provided with, and can adapt to oxygen therapy and insert the situation that stomach will carry out simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Its face shield 1 of present embodiment and gas receiver 3 two parts are connected together by seam 10 as can be seen from Figure 1, oxygen inputs in the gas receiver 3 by oxygen catheter 2, the top of gas receiver 3 is provided with breather check valve 4, mouth and nose the place ahead of face shield 1 is provided with exhaust check valve 5, breather check valve 4 is formed by central authorities' diaphragm seal 7 of connection of vavle shelf 6, diaphragm seal 7 is towards gas receiver 3, the structure of exhaust check valve 5 is identical with breather check valve 4, but direction is opposite when installing, its diaphragm seal is outside face shield 1, the diaphragm seal 7 of breather check valve 4 is picked up from periphery when patient inhales, air enters gas receiver 3 thus, be inhaled into the human lung together in company with the oxygen in the gas receiver 3, this moment, exhaust check valve sealed, and when patient need exhale, the waste gas that the diaphragm seal of exhaust check valve 5 is breathed out was washed open from periphery, waste gas is got rid of thus, because the waste gas Main Ingredients and Appearance is CO
2, it is heavier than oxygen, thus gas receiver in oxygen can run out of hardly thereupon, this moment breather check valve diaphragm seal 7 set back, still be adsorbed on vavle shelf 6 upper sealing valve framves 6.It can also be seen that from Fig. 1, have an aperture 8 in a side of exhaust check valve, be used for inserting stomach tube, be applicable to that oxygen therapy inserts the situation that stomach carries out simultaneously, is cappings during aperture 8 not enableds.Elastic cord 9 has also been installed in the both sides of face shield 1, is used for face shield 1 is fixed in face, and face shield 1 is closely pasted to reach sealing effectiveness mutually with face.From the health mirror, present embodiment is made disposable better, and its material can adopt non-toxic plastic etc.
