Description

TECHNICAL FIELD

[0001] The present application belongs to medical devices, and particularly relates to a connecting device for a humidification therapy instrument. BACKGROUND

[0002] There are a large number of patients in clinic who need to be tracheotomized for the sake of operation safety or emergency treatment. The respiratory airflow of these patients does not pass through the nasal mucosa for warming and humidification, which will cause the respiratory tract of the patients to be dry and bitter, and the patients to have a lot of sputum, and even cause infection. Therefore, the respiratory airflow needs to be warmed and humidified, and a high-flow humidification instrument or a positive pressure atomization humidification therapy instrument is often used for humidification treatment. Figure 1 After tracheotomy, the doctor places the cannula a of the tracheostomy tube I in the respiratory tract of the patient, and connects the connecting heads c and d of the extension tube II with the joint b of the tracheostomy tube I and the breathing tube of the humidification therapy instrument respectively. The gas humidified by the humidification therapy instrument is sent into the tracheostomy tube I through the breathing tube and the extension tube II. The extension tube II is provided with an exhaust hole e so as to discharge the exhaled gas of the patient. Under the condition that the positive pressure is maintained in the breathing tube, the exhaled gas of the patient cannot enter the extension tube. It is found during use that some patients have serious breath retention, carbon dioxide retention, and sputum coughing difficulty, and the sputum of the patients needs to be sucked in time by nursing, and if the sputum is not treated in time, a medical accident will be caused. SUMMARY

[0003] The present application aims at the problems existing in the prior art, and provides a connecting device for a humidification therapy instrument, which can better solve the breath retention and sputum coughing difficulty of patients.

[0004] The technical scheme of the present application is as follows: The connecting device for the humidification therapy instrument provided by the present application comprises a hollow cover body, a breathing tube interface provided on the cover body and connected with the breathing tube of the humidification therapy instrument, and a plug hole provided at the lower part of the cover body and connected with the joint of the tracheostomy tube. An exhaust hole deviating from the plug hole is provided on the breathing tube interface or the cover body.

[0005] A first soft film is provided at the lower part of the cover body, and the plug hole is provided on the first soft film.

[0006] An adapter is further included, the plug hole of the first soft film is connected with the joint of the tracheostomy tube through the adapter, and the adapter comprises a pipe body and a radially extending edge provided on the outer periphery of the pipe body.

[0007] The breathing tube interface is provided on the upper part of the cover body through an elbow, or is provided on the side surface of the cover body.

[0008] The maximum flow cross section of the cover body is at least 3 times the flow cross section of the joint of the tracheostomy tube.

[0009] The elbow or the cover body is provided with an anti-choking hole and a second soft film capable of covering the anti-choking hole.

[0010] The elbow or the cover body is provided with a socket, and the second soft film is arranged in the elbow or the cover body by matching the socket with the socket seat.

[0011] The breathing tube interface comprises a socket arranged on the elbow or the cover body and a connecting pipe sleeved with the socket, and the exhaust hole is arranged on the connecting pipe.

[0012] The cover body is provided with a connecting socket, and the elbow or the breathing tube interface is connected to the connecting socket of the cover body.

[0013] The first soft film is provided with a groove at the connecting position with the cover body.

[0014] Advantages of the present application The prior art causes some patients to hold their breath and retain carbon dioxide, and the reason is not clear in clinical practice, so the problem has not been effectively solved. It is found through in-depth observation that after humidification treatment, the sputum of the patient is relatively thin, and the patient can easily cough it out. In the prior art, the direction in which the patient coughs out sputum is basically consistent with the direction of the exhaust hole, the diameter of the exhaust hole is relatively small, the sputum of the patient can reach the exhaust hole, the sputum stays in the exhaust hole, and the exhaust hole is blocked or partially blocked. The smaller the diameter of the exhaust hole, the easier it is to block the sputum. Due to the existence of the exhaust hole, a part of the gas will inevitably leak from the exhaust hole without being inhaled by the patient. The gas humidified by the humidification instrument includes the amount of gas inhaled by the patient and the amount of leakage. The larger the amount of leakage, the higher the requirement for humidification of the humidification instrument, the greater the consumption of clean water, and the greater the workload of medical staff to add water. Therefore, the diameter of the exhaust hole of the extension tube is usually not more than 6 mm. When the diameter of the exhaust hole is larger, the humidification instrument on the market cannot meet the humidification requirements of the patient. The applicant sets the exhaust hole at a position deviating from the airflow direction of the tracheostomy cannula outlet, so that the sputum cannot reach the exhaust hole of the elbow, thereby completely solving the problem of sputum blocking the exhaust hole, without the need to make the diameter of the exhaust hole very large, avoiding the occurrence of medical accidents, and improving the treatment quality of the patient.

[0015] Meanwhile, the cover body with an obviously larger flow cross section than the tracheostomy cannula makes the sputum quickly reduce the flow rate and fall after entering the cover body, so that the sputum cannot reach the exhaust hole of the breathing tube interface or the cover body. The cover body with a relatively large size is arranged, and the airflow discharge direction deviates from the airflow direction of the tracheostomy cannula outlet, so that the falling track of the sputum deviates from the opening of the tracheostomy cannula, and the sputum stays in the first soft film of the cover body. The cover body becomes a sputum collector, and medical staff can conveniently remove the sputum by using a sputum suction device.

[0016] The lower part of the cover body is provided with the first soft film. When the patient moves the head, the cover body can move, and at the same time, the connection between the cover body and the tracheostomy cannula can be sealed, thereby reducing the influence of the cover body on the movement of the patient.

[0017] The adapter is arranged between the tracheal incision cannula and the cover body. In use, the edge of the adapter can provide limiting and supporting effect for the first soft film, and the first soft film seals the airflow under the action of the airflow pressure of the humidification instrument to prevent the gas from leaking out from the connection between the cover body and the adapter.

[0018] The technical solutions of the present application will be further described below with reference to the drawings. BRIEF DESCRIPTION OF DRAWINGS

[0027] See Figure 2 , Figure 3 The connecting device for the humidification therapy instrument provided by the present application comprises a hollow cover body 1, an elbow 5 arranged on the upper part of the cover body 1, and a first soft film 4 covering the lower part of the cover body 1, wherein the first soft film 4 is provided with a jack 13 connected with the connector b of the tracheal incision cannula I, the elbow 5 is provided with a breathing tube interface connected with the breathing tube of the humidification therapy instrument, an anti-choking hole 12, and a second soft film 7 capable of covering the anti-choking hole 12, and the breathing tube interface is provided with an exhaust hole 10 deviated from the jack 13.

[0028] Further: The breathing tube interface includes an interface 9 on the elbow 5 and a connecting tube 11 sleeved with the interface 9, and the exhaust port 10 is provided on the connecting tube 11; the elbow 5 is provided with a socket 8, and the second soft membrane 7 is provided in the elbow 5 through a socket seat 6 and cooperates with the socket 8; the cover 1 is provided with a connecting port 2, and the elbow 5 is connected to the connecting port 2 of the cover 1; the first soft membrane 4 at the lower part of the cover 1 and the second soft membrane 7 on the elbow 5 are made of silicone material; the first soft membrane 4 is provided with a groove 14 at the connection between the first soft membrane 4 and the cover 1; the cover 1 is provided with strap through holes 3 on both sides; the maximum flow cross section of the cover 1 is at least 3 times the flow cross section of the tracheostomy sleeve I connector b; the diameter of the anti-suffocation hole 12 on the elbow 5 and the diameter of the exhaust port 10 on the connecting tube 11 are preferably 8mm and 5mm, respectively.

[0029] The lower part of the cover 1 may not have the first soft membrane 4, and the insertion hole 13 that connects to the connector b of the tracheostomy tube I is located in the lower part of the cover 1.

[0030] Use of this invention: see Figure 4 , Figure 5 After the doctor places the endotracheal cannula a of the tracheostomy tube I into the patient's airway, the first soft membrane 4 at the bottom of the mask 1 is sealed to the connector b of the tracheostomy tube I through the insertion hole 13. The heated and humidified airflow provided by the humidification therapy device enters the tracheostomy tube I through the breathing tube interface of the elbow 5 and the mask 1 to treat the patient. Since the heated and humidified airflow provided by the humidification therapy device is always at positive pressure, it can force the second soft membrane 7 on the elbow 5 to adhere to the anti-asphyxiation hole 12 and seal it. When the patient exhales normally, the pressure of the exhaled airflow can resist the pressure of the heated and humidified airflow and be discharged from the exhaust hole 10. When a patient coughs up sputum, the sputum suddenly enters the larger-section hood 1 from the connector b of the tracheostomy cannula I, where the flow cross-section is smaller. Its flow rate immediately decreases, and it falls onto the first soft membrane 4 at the bottom of the hood 1, flowing into the groove 14 for easy collection. It does not reach the exhaust port 10 on the elbow 5 and block it, thus preventing medical accidents caused by blockage of the exhaust port 10. When the humidification therapy device is not in use, the second soft membrane 7 naturally droops under its own weight, opening the anti-asphyxiation hole 12, allowing the patient to breathe normally through it. Figure 6 As shown. Example 2
