Description

CPR artificial respiration isolating membrane

Technical Field

The utility model belongs to the technical field of medical auxiliary instrument, in particular to CPR artificial respiration isolating membrane.

Background

CPR is an important component of cardiopulmonary resuscitation, and is a life-saving technique for sudden cardiac arrest and respiration. The artificial respiration method includes both mouth-to-mouth breathing and mouth-to-nose breathing, and the mouth-to-mouth breathing is the most common and effective way. When the mouth-to-mouth artificial respiration is implemented, a rescuer needs to stand on one side of the head of a patient, firstly sucks breath, then directly blows the breath into the mouth facing the mouth of the sick and wounded, needs to hold the hand on the nostril during the blowing in order to prevent the air from being exposed from the nostril, leaves the mouth of the rescuer, releases the held nostril and simultaneously needs to press the chest. The oral-to-oral artificial respiration has the disadvantages that: (1) diseases are easily transmitted between the rescue personnel and the sick and wounded; (2) the rescue personnel can have psychological obstacles to influence the final treatment effect.

In the prior art, the rescue personnel often use a CPR artificial respiration isolation film to solve the technical problem. One type of isolation membrane is composed of water-absorbing wet cloth and a PVC membrane, and the other type of isolation membrane is composed of a one-way valve and a PVC membrane. When in use, the isolating membrane is spread on the face of a patient, the middle ventilation isolating opening or the one-way valve is aligned with the mouth of the patient, and then mouth-to-mouth artificial respiration is implemented. The disadvantage of the barrier film is that the gas is easily released when the rescuer exhales. Chinese patent application No. 1810054064.8 discloses an artificial respiration device for preventing air leakage during artificial respiration, which comprises the following technical scheme: the utility model provides an inflatable artificial respiration device, is connected with the sealed bag that is used for packing into in order to avoid gas leakage in the person's mouth including aerifing hollow post, the one end of aerifing hollow post, and the shape of sealed bag is the column shape, and sealed bag and aerifing hollow post intercommunication. Although the scheme reduces the probability of air leakage of the expired air of the rescue personnel at the mouth of the patient, the applicability of the form of the sealing bag is not strong because the mouths of different people have different shapes and sizes.

Disclosure of Invention

An object of the utility model is to overcome prior art's is not enough, provides a CPR artificial respiration barrier film, can reduce the probability that the direct contact takes place for rescuer and wounded's oral secretion, can also airtight wounded's nasal cavity simultaneously.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

CPR artificial respiration barrier film, including the barrier film body, the barrier film body sets the air guide intubate of split type setting, and one side of air guide intubate is provided with violently preceding convex part, and horizontal preceding convex part is cut apart into the air guide intubate and is blown the end and give vent to anger the end, is provided with the filter core in the air guide intubate, sets up the confession on the barrier film body and gives vent to anger end male opening, and the protruding horizontal bar of having arranged on the surface of barrier film body, protruding horizontal bar are located the open-ended both sides.

As an improvement, the air guide cannula is flat.

As a further improvement, the transverse forward convex part is in a disc shape.

As a modification, the forward convex length of the transverse forward convex part is 0.5-1 cm.

As an improvement, the length of the air blowing end is 2-4 cm.

As an improvement, the length of the air outlet end is 3-5 cm.

As an improvement, the isolation film body comprises a PVC layer and a water-repellent non-woven fabric layer.

As an improvement, the filter element is made of activated carbon fiber.

The utility model has the advantages that:

before the air guide device is used, the air outlet end of the air guide insertion tube is inserted into the opening, the air guide insertion tube is used for conducting air, and the rescuer holds the air blowing end of the air guide insertion tube by mouth and blows air, so that the conduction efficiency of expiration can be improved, and the leakage of the blown air at the mouth of the rescuer is reduced.

Compared with the isolating membrane in the prior art, the mouth of the rescuer only contains the air blowing end of the air guide cannula, and the interval and the blockage of the transverse forward convex part are arranged between the air blowing end and the air outlet end. Therefore, there is less probability that the mouth of the rescuer will come into direct contact with the victim.

The protruding horizontal bar of opening both sides, protruding horizontal bar mainly has 3 effects: firstly, after the isolating membrane body is laid on the face of the wounded, the rescuer presses the palm around the mouth of the wounded, the raised cross strips are beneficial to increasing the friction force and reducing the slipping between the palm and the isolating membrane body; the convex cross strips are beneficial to curling of the isolation diaphragm body, the isolation diaphragm body above the opening is curled and then placed at the nostril of the wounded and sick person and is supported by the transverse front convex part of the air guide cannula, the nasal cavity of the wounded and sick person can be sealed, so that the rescuer does not need to pinch the nose of the wounded and sick person with hands, and the hands are free; thirdly, when secretion overflows in the nasal cavity or the oral cavity, the raised transverse strips play a role in guiding flow.

For the unconscious wounded persons, the tongue of the patient can droop to block the air from being fed into the trachea, and the length of the air outlet end of the air guide cannula is 3-5 cm. When the blowing end of the air guide cannula inclines towards the nasal cavity, the air outlet end of the air guide cannula inclines towards the tongue direction, so that the tongue of the patient can be pressed in the original position, and the blockage of the tongue to the expiration is reduced. Meanwhile, the air outlet end is close to the throat of the patient, so that the patient can breathe out air and lead the air into the trachea.
