Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an indwelling tube fixation device. Background Technology

[0002] In clinical practice, after a tracheotomy, the trachea is directly exposed to air. Dry air entering the lower respiratory tract directly causes secretions to dry and accumulate, increasing the risk of related complications and even blocking the tracheostomy tube, which can be life-threatening. Therefore, postoperative airway humidification management is necessary. Airway humidification increases the humidity of inhaled air, reduces damage to the airway and lung tissue, maintains the integrity of the ciliary structure, improves the patient's respiratory comfort, and enhances respiratory function.

[0003] Currently, microinfusion pumps are commonly used in clinical practice to provide continuous airway humidification for patients. However, there is a problem in its application: the patient end of the extension tube of the microinfusion pump is not easy to fix. The most common clinical method is to use medical paper tape to stick the extension tube to the patient's chest skin or clothing, and insert the end into the cannula. However, when the patient turns over slightly or coughs, the end is easy to fall off and become contaminated, and it is also easy to wet the patient's clothes, increasing the patient's discomfort. In addition, a specialist is required to frequently insert the end into the cannula, which is time-consuming and laborious. Utility Model Content

[0028] In clinical practice, after a tracheotomy, the trachea is directly exposed to air. Dry air entering the lower respiratory tract directly causes secretions to dry and accumulate, increasing the risk of related complications and even blocking the tracheostomy tube, which can be life-threatening. Therefore, postoperative airway humidification management is necessary. Airway humidification increases the humidity of inhaled air, reduces damage to the airway and lung tissue, maintains the integrity of the ciliary structure, improves the patient's respiratory comfort, and enhances respiratory function.

[0029] In related technologies, the patient end of the extension tube of a microinfusion pump is not easy to fix. When the patient turns over slightly or coughs, the end can easily fall off and become contaminated. It can also easily wet the patient's clothes, increasing the patient's discomfort. In addition, it requires a dedicated person to frequently insert the end into the cannula, which is time-consuming and laborious.

[0030] To address some of the problems in the related technologies, this application provides an indwelling tube fixing device. When it is necessary to connect and fix the tube, simply insert the connecting sleeve 21 onto the tracheostomy sleeve 11 and fix it to the patient's neck with the fixing strap 23. When it is necessary to humidify the patient's airway, insert the connector 241 at one end of the micro-infusion pump extension tube into the connecting port 24 on the outside of the connecting sleeve 21. Then, push the threaded sleeve 251 on the outside of the connector 241 onto the thread 25 on the outside of the connecting port 24 and rotate the threaded sleeve 251 to fix the connector 241 and the connecting port 24 with threads.

[0031] This application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figures 1-3 This application provides a device for fixing an indwelling tube, including an indwelling tube body 1. The indwelling tube body 1 includes: a fixing connection component 2 disposed on the outside of an air-cutting sleeve 11; the fixing connection component 2 includes: a connecting sleeve 21 sleeved on the outside of the air-cutting sleeve 11 and connected to the air-cutting sleeve 11 by a socket; a support plate 22 disposed at one end of the connecting sleeve 21 and sleeved on the outside of the air-cutting sleeve 11; a fixing strap 23 passing through the support plate 22 and fixed by Velcro; a connecting port 24 symmetrically disposed on the outside of the connecting sleeve 21, and a micro-injection pump extension tube disposed on the connecting port 24; a connector 241 disposed at one end of the micro-injection pump extension tube and connected to the connecting port 24 by a socket; a thread 25 disposed on the outside of the connecting port 24, and a threaded sleeve 251 that matches the thread 25 disposed on the outside of the connector 241, so that the connecting port 24 and the connector 241 are threadedly fixed.

[0033] After the tracheostomy tube 11 is inserted into the trachea in the patient's neck and fixed, the connecting tube 21 is inserted onto the tracheostomy tube 11 and fixed to the patient's neck with the fixing strap 23. When airway humidification is required, the connector 241 at one end of the microinfusion pump extension tube is inserted into the connecting port 24 on the outside of the connecting tube 21. Then, the threaded sleeve 251 on the outside of the connector 241 is pushed onto the thread 25 on the outside of the connecting port 24, and the threaded sleeve 251 is rotated to fix the connector 241 to the connecting port 24. This increases the fixation and stability of the microinfusion pump extension tube connection on the patient's tracheostomy tube 11 and prevents the tube from falling off when the patient coughs or moves their neck. After fixation, the microinfusion pump is started to inject humidifying fluid into the patient's trachea through the extension tube.

[0034] In some embodiments, a threaded cap 29 with mating threads 25 is provided on the connection port 24. When the connection port 24 is not in use, the threaded cap 29 can be screwed onto the connection port 24 to seal the connection port 24.

[0035] In some embodiments, a sealing plate 26 is provided on the outer side of the connection port 24 to cooperate with the threaded sleeve 251 and the threaded cover 29, and is located at one end of the threaded sleeve 251 and the threaded cover 29. When the threaded sleeve 251 and the threaded cover 29 are screwed onto the connection port 24, one end of the threaded sleeve 251 and the threaded cover 29 will abut against the sealing plate 26, thereby increasing the sealing performance of the connection port 24 and the connector 241.

[0036] Specifically, the sealing plate 26 consists of a support plate and a sealing gasket, which allows the threaded sleeve 251 and the threaded cap 29 to cooperate with the support plate to compress the sealing gasket, thereby forming a seal.

[0037] In some embodiments, a limiting plate 252 that engages with the threaded sleeve 251 is provided on the outer side of the connector 241 to limit the threaded sleeve 251 and prevent the threaded sleeve 251 from being lost from the connector 241.

[0038] In some embodiments, the other end of the connecting sleeve 21 is provided with a suction port 27, which facilitates the connection between the suction device and the connecting sleeve 21 for the patient to expel sputum.

[0039] In some embodiments, a sealing gasket 211 is provided on the inner side of one end of the connecting sleeve 21 to cooperate with the tracheostomy tube 11, which increases the sealing of the connection between the connecting sleeve 21 and the tracheostomy tube 11 and prevents the humidifying liquid from leaking through the gap between the connecting sleeve 21 and the tracheostomy tube 11 when the micro-infusion pump injects humidifying liquid into the patient's trachea through the extension tube.

[0040] In some embodiments, a one-way valve 28 is provided inside the connection port 24 to prevent sputum from entering the connection port 24 during the patient's expectoration, thus avoiding contamination and blockage.

[0041] In some embodiments, multiple sets of connection ports 24 are provided on the outside of the connecting sleeve 21, which are respectively connected to the extension tube of the micro-infusion pump and the oxygen tube, so as to provide oxygen to the patient in real time and perform tracheal humidification operation.
