Description

Leak protection gas's lung function inspection seaming

Technical Field

The utility model relates to an air leakage prevention lung function examination seaming, and belongs to the technical field of medical products.

Background

In the case of lung function tests, a disposable mouthpiece is required at the patient end of the instrument. During detection, a patient needs to open the mouth, mouthpiece and close the mouth to inhale and exhale. In clinical work, patients who frequently encounter facial paralysis, rabbit lips, poliomyelitis and the like and cannot close their mouths need to detect lung functions, diagnosis and treatment are carried out on the diseases, and the patients are also often accompanied by uncontrollable tongues. Often, because of air leakage from the mouth and blockage of the tongue, inspection or quality control criteria cannot be achieved. Patients whose mouth cannot be closed, leak gas during inspiration and expiration, often resulting in failure of detection or reduced levels of true lung capacity; patients whose tongue is uncontrollable often have their tongue extending into the bite block the bite channel, resulting in failure of the test. The existing seaming is cylindrical, lips are not attached to the seaming, and the corners of the mouth of a patient are prone to air leakage, so that detection fails or the real lung capacity level of the patient is reduced.

Disclosure of Invention

The utility model aims to solve the technical problems that: the problem of how to prevent or reduce mouth leakage and how to prevent the tongue from blocking the bite when performing lung function tests on patients whose mouth cannot be closed and/or whose tongue cannot be controlled.

In order to solve the technical problems, the technical scheme of the utility model provides an anti-leakage lung function examination seaming, which comprises a seaming connecting pipe, one end of the seaming connecting pipe is connected with a filter, the other end of the seaming connecting pipe is connected with one end of the seaming pipe, and the other end of the seaming pipe is connected with a tongue-and-groove piece; the two sides of the mask are respectively provided with a headband which is used for being fixed on the head of a patient and can adjust the tightness; the mask is of an airtight structure; when the headband is fixed on the head of a patient, the mask completely covers the mouth of the patient.

Preferably, the seaming tube is of a flat type structure.

Preferably, the seaming connecting pipe is in transitional connection with the seaming pipe through a slope structure.

Preferably, the tongue-and-groove piece is arranged on one side wall of the seaming pipe; the shape of the tongue-and-groove piece is matched with the shape of the side wall of the seaming pipe.

Preferably, teeth marks for the occlusion of the patient are uniformly distributed on the seaming tube.

Preferably, the mask is concave towards one side of the seaming tube.

Compared with the prior art, the utility model has the following advantages:

the utility model has the advantages of simple design, convenient use, improved comfort level of patients, improved success rate of clinical detection and ensured detection accuracy. Solves the problems of air leakage of the mouth and tongue blocking of the mouth of a patient, helps the patient with facial paralysis, rabbit lip, poliomyelitis and the like, who can not be closed and/or can not be controlled by the tongue, to finish the lung function detection, and carries out clinical diagnosis and treatment on the diseases.

By using the mouthpiece provided by the utility model, the mouth of a patient is tightly wrapped by the silica gel mask on the mouthpiece, and the two head bands on the mask are worn on the head, so that tightness can be adjusted, air leakage is prevented, and meanwhile, the tongue is pressed below the mouthpiece by the tongue pressing piece at the front end of the mouthpiece, so that the tongue of the patient can be effectively prevented from blocking the mouthpiece, detection accuracy is ensured, and clinical success rate is improved.

Detailed Description

In order to make the utility model more comprehensible, preferred embodiments accompanied with figures are described in detail below.

The utility model provides an air leakage prevention lung function examination seaming, which is used for lung function examination of patients with unclosed mouth, such as facial paralysis, rabbit lip, poliomyelitis and the like, and as shown in fig. 1 and 2, the utility model comprises a seaming connecting pipe 1, one end of which is connected with a filter, the other end of the seaming connecting pipe 1 is connected with one end of a seaming pipe 8, the other end of the seaming pipe 8 is connected with a tongue-pressing piece 6, and the seaming connecting pipe 1, the seaming pipe 8 and the tongue-pressing piece 6 are of an integrated structure. The seaming tube 8 is of a flat type structure. The seaming connecting pipe 1 is in transitional connection with the seaming pipe 8 through the slope structure 4. The tongue-and-groove piece 6 is arranged on one side wall of the seaming pipe 8; the shape of the tongue-and-groove piece 6 matches the shape of the side wall of the seaming tube 8. Tooth marks 5 for the occlusion of a patient are uniformly distributed on the seaming tube 8. The mouth-piece connecting pipe 1 is provided with a mask 2 which only covers the mouth of a patient in a penetrating way, a penetrating hole which can be penetrated by the mouth-piece connecting pipe 1 is arranged in the middle of the mask 2, the outer wall of the mouth-piece connecting pipe 1 is in sealing connection with the inner wall of the penetrating hole of the mask 2, the side surface of the mouth-piece pipe 8 is provided with at least one side hole 7, and the side hole 7 is communicated with the inner cavity of the mouth-piece pipe 8; the two sides of the mask 2 are respectively provided with a headband 3 which is sleeved on the head of a patient and can adjust tightness. The mask 2 is of an airtight structure; the mask 2 completely covers the patient's mouth when the headband 3 is fixed to the patient's head.

In this embodiment, two opposite sides of the side of the seaming tube 8 are respectively provided with a side hole 7.

The mask 2 is made of flexible silica gel, so that the mouth can be tightly wrapped; the tightness of the two head bands 3 can be adjusted to prevent air leakage; the mask 2 is concave towards the direction of the oral cavity (namely the direction of the seaming tube 8), and the two sides of the seaming tube 8 are provided with hollowed-out channels, namely side holes 7.

The application process of the utility model is as follows:

firstly, the seaming connecting pipe 1 on the seaming of the utility model is connected with a filter, the filter is connected with a pulmonary function instrument, then the seaming pipe 8 on the seaming of the utility model is connected with the tongue pressing piece 6 to extend into the oral cavity of a patient, the tongue pressing piece 6 is pressed on the tongue of the patient, the patient bites the seaming pipe 8, lips are stuck on the slope structure 4, and simultaneously, the two head bands 3 are sleeved on the head of the patient, so that the mouth of the mask 2 is tightly packed, and finally, the pulmonary function of the patient is checked. Since the mouthpiece 8 is provided with the tooth trace 5, the patient bites on the mouthpiece 8, preventing the mouthpiece 8 from sliding in the patient's mouth. Since the tongue depressor 6 presses against the patient's tongue, the patient's tongue is prevented from extending into the mouthpiece 8, thereby blocking the bite.

The gas exhaled by the patient can be directly exhaled through the passage in the mouthpiece 8; meanwhile, the gas leaked from the mouth corners of the patient with the mouth corners incapable of being closed is blocked by the mask 2, and enters the inner cavity channel in the seaming tube 8 through the side holes 7 to exhale the gas, so that the problem of gas leakage is reduced or avoided as much as possible.

Even if the patient's tongue is uncontrolled, when the tongue would block the port of the mouthpiece 8, the exhaled air from the patient can enter the lumen passage in the mouthpiece 8 through the side hole 7 to exhale. The success rate of the detection is improved and the probability of the patient reaching the true lung capacity level is improved.
