Description

Technical Field

[0001] This utility model belongs to the technical field of oxygen supply devices, specifically relating to an oxygen supply device for intensive care. Background Technology

[0002] Intensive care refers to the centralized and intensive treatment and nursing care provided to critically ill patients using various advanced medical technologies and modern monitoring and resuscitation equipment. Among these, oxygen therapy is a very important treatment technique in intensive care, as oxygen inhalation through an oxygen supply device can improve patients' hypoxemia and alleviate respiratory distress.

[0003] In existing intensive care oxygen supply devices, the humidification bottle is connected to the top cover by inserting the top of the humidification bottle into the bottom of the top cover and connecting them by threads. If the humidification bottle or the top cover is accidentally screwed on, the connection between the two will become loose, resulting in problems such as unstable connection and air leakage. Therefore, this utility model proposes an intensive care oxygen supply device. Utility Model Content

[0004] The purpose of this invention is to provide an intensive care oxygen supply device to solve the problem of unstable connection between the humidification bottle and the top cover, which is connected by threads as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intensive care oxygen supply device, comprising a humidification bottle, a top cover disposed at the top of the humidification bottle, and a protective sleeve disposed at the top of the top cover. A connecting mechanism is provided between the top cover and the humidification bottle. The connecting mechanism consists of a slot and a fixing component. The slot is located at the bottom of the top cover. The top of the humidification bottle is inserted into the inner side of the slot and connected by a thread. The fixing component consists of a groove, a limiting groove, a limiting block, and a spring assembly. The groove is located on the side of the humidification bottle. The limiting groove is located on the side of the top cover. The limiting block is disposed inside the groove and the limiting groove. The spring assembly is disposed inside the groove.

[0006] Preferably, the cross-section of the limiting block is rectangular.

[0007] Preferably, the spring assembly consists of a limiting groove, a limiting slide post, and a spring body. The limiting groove is formed on the side of the limiting block, and the limiting slide post is disposed inside the groove and the limiting groove. The end of the limiting slide post is fixed to the end of the groove, the spring body is sleeved on the surface of the limiting slide post, and the two ends of the limiting slide post are respectively fixed to the bottom of the limiting block and the groove.

[0008] Preferably, the limiting slide is a cylindrical structure.

[0009] Preferably, the side cross-section of the limiting slide column is T-shaped, and the side cross-section of the limiting slide groove is rectangular.

[0010] Preferably, a flow tube is provided on the inner side of the sheath, and a flow float is provided on the inner side of the flow tube.

[0011] Preferably, the humidification bottle is provided with a vent tube on its inner side, a connecting tube interface is provided on one side of the top cover, and a nasal oxygen tube interface is provided on the other side of the top cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing a connection mechanism, the original intensive care oxygen supply device was improved. When installing the humidifier bottle and top cover, the two were only connected by threads. If the humidifier bottle was accidentally rotated after connection, the connection would become loose. By setting a connection mechanism between the humidifier bottle and top cover, a limiting structure is added to the original connection. When the top of the humidifier bottle is inserted into the inner side of the slot, the connection is simultaneously limited by the slot during the threaded rotation connection, increasing the connection stability.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3This utility model provides a technical solution: an intensive care oxygen supply device, including a humidification bottle 1, a top cover 2 disposed at the top of the humidification bottle 1, and a protective sleeve 4 disposed at the top of the top cover 2. A connecting mechanism 3 is provided between the top cover 2 and the humidification bottle 1. The connecting mechanism 3 consists of a slot 31 and a fixing component 32. The slot 31 is opened at the bottom end of the top cover 2. The top of the humidification bottle 1 is inserted into the inner side of the slot 31 and connected by threads. The fixing component 32 consists of a groove 321, a limiting groove 322, a limiting block 323, and a spring component 324. When the humidification bottle 1 is threadedly connected to the slot 31, it is fixed by the fixing component 32. The groove 321 is opened on the side of the humidification bottle 1, the limiting groove 322 is opened on the side of the top cover 2, the limiting block 323 is disposed inside the groove 321 and the limiting groove 322, and the spring component 324 is disposed inside the groove 321. Through the designed connecting mechanism 3, the system is improved. Previously, during the use of the intensive care oxygen supply device, when it was necessary to install the humidification bottle 1 and the top cover 2, the two were only connected by threads. After connection, if the humidification bottle 1 was accidentally rotated, the connection would become loose. By setting a connection mechanism 3 between the humidification bottle 1 and the top cover 2, a limiting structure was added to the original connection. When the top of the humidification bottle 1 is inserted into the inner side of the slot 31, during the threaded rotation connection, the slot 31 simultaneously limits the connection, increasing the stability of the connection. The limiting block 323 has a rectangular cross-section. The inner side of the sheath 4 is equipped with a flow tube 5, and the inner side of the flow tube 5 is equipped with a flow float. The inner side of the humidification bottle 1 is equipped with a ventilation tube. One side of the top cover 2 is equipped with a connecting pipe interface, through which an external oxygen cylinder is connected to the oxygen supply device. The other side of the top cover 2 is equipped with a nasal oxygen tube interface, through which the external oxygen tube is connected to the nasal oxygen tube interface of the oxygen supply device.

[0020] In this embodiment, preferably, the spring assembly 324 comprises a limiting groove 3241, a limiting slide post 3242, and a spring body 3243. The limiting groove 3241 is formed on the side of the limiting block 323, and the limiting slide post 3242 is disposed inside the groove 321 and the limiting groove 3241. The end of the limiting slide post 3242 is fixed to the end of the groove 321. The spring body 3243 is sleeved on the surface of the limiting slide post 3242, and both ends of the limiting slide post 3242 are fixed to the bottom ends of the limiting block 323 and the groove 321, respectively. When the limiting block 323 is pressed by an external force, the limiting block 323 is engaged. The spring block 323 is compressed. When the limiting block 323 loses external pressure, the limiting block 323 is pushed out by the elastic force of the spring body 3243. The limiting block 323 is limited by the limiting position of the end of the limiting slide column 3242 inside the limiting slide groove 3241. The limiting slide column 3242 is cylindrical and has a T-shaped cross-section. The limiting slide groove 3241 has a rectangular cross-section.

[0021] The working principle and usage of this utility model are as follows: When a patient in the intensive care unit is receiving oxygen, the oxygen supply device is connected to an external oxygen cylinder. The patient wears an external oxygen tube, and the other end of the external oxygen tube is connected to the nasal cannula interface of the oxygen supply device. During operation, the dry oxygen in the external oxygen cylinder is mixed with water vapor through the oxygen supply device to increase the oxygen humidity. This mixture is then transmitted through the external oxygen tube, allowing the patient to inhale the oxygen. When it is necessary to connect the humidification bottle 1 to the top cover 2, the protruding limiting block 323 is pressed, causing it to embed into the inner side of the groove 321, and compressing the spring body 3243. Insert the top of the humidification bottle 1 into the inner side of the bottom of the top cover 2, and simultaneously loosen the limiting block 323. The limiting block 323 is pushed out by the elastic force of the compressed limiting slide 3242. Due to the restriction of the inner wall of the hand-fixed component 32, the limiting block 323 is still stored in the groove 321. By rotating the humidification bottle 1, the humidification bottle 1 is threadedly connected to the slot 31. When the humidification bottle 1 is fully engaged with the slot 31, and the limiting block 323 is aligned with the limiting groove 322, the limiting block 323 is inserted into the inner side of the limiting groove 322 by the elastic force of the limiting slide 3242, thus completing the installation operation of the humidification bottle 1 and the top cover 2.
