Description

Technical Field

[0001] The utility model belongs to medical equipment, and in particular relates to a connecting device for a humidification therapeutic apparatus. Background Art

[0002] In clinical practice, a large number of patients need tracheotomy for surgical safety or emergency treatment. Since the respiratory airflow of these patients does not pass through the nasal mucosa for heating and humidification, it will cause dry and bitter respiratory tract, excessive sputum, and even infection. Therefore, it is necessary to heat and humidify the respiratory airflow, and high-flow humidifiers or positive pressure atomization humidification therapy devices are often used for humidification therapy. Figure 1 After tracheotomy, the doctor places the cannula a of the tracheotomy tube Ⅰ in the patient's respiratory tract, and connects the connectors c and d of the extension tube Ⅱ to the connector b of the tracheotomy tube Ⅰ and the breathing tube of the humidification therapy device respectively. The humidified gas of the humidification therapy device is sent to the tracheotomy tube Ⅰ through the breathing circuit and the extension tube Ⅱ. The extension tube Ⅱ has an exhaust hole e to allow the patient's exhaled gas to be discharged. When the breathing circuit maintains a positive pressure, the gas discharged by the patient cannot enter the long breathing tube. During use, it was found that some cases had severe patient breath holding, carbon dioxide retention, and difficulty in expectoration, which required timely nursing and suction of sputum. If not handled in time, it will cause medical accidents. Utility Model Content

[0003] The utility model aims to provide a connection device for a humidification therapy apparatus which can better solve the problems of holding breath and coughing up phlegm for patients, in view of the problems existing in the prior art.

[0004] The technical solution of the utility model is achieved in this way:

[0005] The utility model provides a connecting device for a humidification therapy apparatus, comprising a hollow cover body, a breathing tube interface provided on the cover body and connected to a breathing tube of the humidification therapy apparatus, and a plug hole provided at the lower part of the cover body and connected to a joint of a tracheotomy tube, wherein an exhaust hole deviating from the plug hole is provided on the breathing tube interface or the cover body.

[0006] A first soft film is arranged at the lower part of the cover body, and the insertion hole is arranged on the first soft film.

[0007] It also includes an adapter, through which the jack of the first soft film is connected to the joint of the tracheotomy tube, and the adapter includes a tube body and an edge that is arranged outside the tube body and extends radially.

[0008] The breathing tube interface is arranged on the upper part of the cover body through an elbow, or is arranged on the side of the cover body.

[0009] The maximum flow cross section of the cover body is at least 3 times the flow cross section of the tracheotomy tube connector.

[0010] The elbow or the cover body is provided with an anti-suffocation hole and a second soft film capable of covering the anti-suffocation hole.

[0011] The elbow or the cover is provided with a socket, and the second soft film is arranged in the elbow or the cover through a socket seat in cooperation with the socket.

[0012] The breathing tube interface comprises an interface arranged on an elbow or a cover body and a connecting pipe sleeved with the interface, and the exhaust hole is arranged on the connecting pipe.

[0013] The cover body is provided with a connecting port, and the elbow or the breathing tube interface is connected to the connecting port of the cover body.

[0014] A groove is provided at the connection between the first soft film and the cover body.

[0015] Beneficial effects of the utility model

[0016] When the existing technology is used, some cases cause patients to hold their breath and retain carbon dioxide. The reasons are not clear in clinical practice, so it has not been effectively solved. In-depth clinical observations have found that after humidification treatment, the patient's sputum is relatively thin and the patient is easier to cough up. In the existing technical solution, the direction of the patient's coughing up sputum is basically consistent with the direction of the exhaust hole. The diameter of the exhaust hole is small, and the patient's coughed sputum can reach the exhaust hole. The sputum stays in the exhaust hole, blocking the exhaust hole or partially blocking the exhaust hole. The smaller the diameter of the exhaust hole, the easier it is for the sputum to block. Due to the existence of the exhaust hole, there must be a part of the gas leaking from the exhaust hole without the patient's breathing. The gas heated and humidified by the humidifier contains the amount of gas breathed by the patient and the amount of leakage. The larger the leakage, the higher the humidification requirements for the humidification therapy instrument, the greater the consumption of clean water, and the greater the workload of medical care to add water. Therefore, the exhaust hole of the extension tube is usually not more than 6mm. When the diameter of the exhaust hole is larger, the humidifier on the market can hardly meet the patient's humidification requirements. Based on this situation, the applicant set the exhaust hole away from the air flow direction at the outlet of the tracheotomy tube to prevent sputum from reaching the exhaust hole at the elbow, thereby completely solving the problem of sputum blocking the exhaust hole. There is no need to make the exhaust hole too large, thus avoiding medical accidents and improving the quality of patient treatment.

[0017] At the same time, a mask with a flow cross-section significantly larger than that of the tracheotomy tube is used, so that the sputum quickly reduces its flow rate and falls after entering the mask, and does not reach the breathing tube interface or the exhaust hole of the mask. A mask with a larger size is set, and the airflow discharge direction deviates from the airflow direction at the outlet of the tracheotomy tube, so that the sputum falling trajectory deviates from the opening of the tracheotomy tube, so that the sputum remains in the first soft membrane of the mask, and the mask becomes a sputum collector, and medical staff can easily remove the sputum using a sputum suction device.

[0018] The lower part of the mask body adopts the first soft film, and when the patient's head moves, the mask body can move, and at the same time, the connection between the mask body and the tracheotomy tube can be sealed, thereby reducing the influence of the mask body on the patient's activities.

[0019] An adapter is arranged between the tracheotomy sleeve and the mask body. When in use, the edge of the adapter can provide a limiting and supporting function for the first soft film, and the first soft film seals the airflow under the airflow pressure of the humidifier to prevent gas from leaking from the connection between the mask body and the adapter.

[0029] See Figure 2 , Figure 3 The utility model provides a connecting device for a humidification therapy device, comprising 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 plug hole 13 connected to the joint b of the tracheotomy tube I, the elbow 5 is provided with a breathing tube interface connected to the breathing tube of the humidification therapy device, an anti-suffocation hole 12 and a second soft film 7 that can cover the anti-suffocation hole 12, and the breathing tube interface is provided with an exhaust hole 10 deviating from the plug hole 13.

[0030] Further: the breathing tube interface includes an interface 9 arranged on the elbow 5 and a connecting pipe 11 sleeved with the interface 9, and the exhaust hole 10 is arranged on the connecting pipe 11; the elbow 5 is provided with a socket 8, and the second soft film 7 is arranged in the elbow 5 through a socket seat 6 and cooperates with the socket 8; the cover body 1 is provided with a connecting port 2, and the elbow 5 is connected to the connecting port 2 of the cover body 1; the first soft film 4 at the lower part of the cover body 1 and the second soft film 7 on the elbow 5 are made of silicone material; a groove 14 is provided at the connection between the first soft film 4 and the cover body 1; strap perforations 3 are provided on both sides of the cover body 1; the maximum flow cross-section of the cover body 1 is at least 3 times the flow cross-section of the tracheotomy tube Ⅰ joint b; the diameter of the anti-suffocation hole 12 on the elbow 5 and the diameter of the exhaust hole 10 on the connecting pipe 11 are preferably 8mm and 5mm respectively.

[0031] The first soft film 4 may not be provided at the lower part of the mask body 1 , and the insertion hole 13 connected to the joint b of the tracheotomy tube I is provided at the lower part of the mask body 1 .

[0032] Use of this utility model: See Figure 4 , Figure 5 After the doctor places the cannula a of the tracheotomy tube I in the patient's respiratory tract, the first soft film 4 at the lower part of the mask body 1 is sealed and connected to the joint b of the tracheotomy tube I through the insertion hole 13, and the heated and humidified airflow provided by the humidification therapy device enters the tracheotomy tube I through the breathing tube interface of the elbow 5 and the mask body 1 to treat the patient. Since the heated and humidified airflow provided by the humidification therapy device is always positive pressure, the second soft film 7 on the elbow 5 can be forced to stick to the anti-suffocation hole 12 and seal. 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 the patient coughs up sputum, the sputum suddenly enters the mask body 1 with a larger flow cross section from the joint b of the tracheotomy tube Ⅰ with a smaller flow cross section. The flow rate of the sputum is suddenly reduced and falls to the first soft film 4 at the bottom of the mask body 1, and flows into the groove 14 for easy collection. It will not reach the exhaust hole 10 on the elbow 5 to block the exhaust hole 10, thus avoiding medical accidents caused by blockage of the exhaust hole 10. When the humidification therapy device is stopped, the second soft film 7 naturally sags under the action of its own gravity to open the anti-suffocation hole 12, and the patient can breathe normally through the anti-suffocation hole 12. Figure 6 shown. Example 2

[0033] See Figure 7, based on the embodiment 1, this embodiment adds an adapter disposed between the tracheotomy tube Ⅰ and the mask body 1, and the insertion hole 13 of the first soft film 4 is connected to the joint of the tracheotomy tube Ⅰ through the adapter; the adapter includes a tube body 15 and an edge 16 disposed outside the tube body 15 and extending radially. When in use, since the portion where the mask body 1 is connected to the adapter adopts the first soft film, the edge 16 provides a limiting and supporting function for the first soft film 4, and the connection portion between the edge 16 and the mask body 1 is smooth, the first soft film 4 seals the airflow under the airflow pressure of the humidifier, and can prevent gas from leaking from the connection between the mask body 1 and the adapter. Example 3

[0034] See Figure 8 In this embodiment, no elbow is provided. Instead, a breathing tube interface connected to the breathing tube of the humidification therapy device, an anti-suffocation hole 12 and a second soft film 7 that can cover the anti-suffocation hole 12 are directly provided on the side of the cover body 1.
