Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a tracheostomy catheter protection and sputum collection device. Background Technology

[0002] Tracheostomy is an important procedure for establishing an artificial airway in the resuscitation of critically ill patients, leaving a tracheostomy tube in the patient's neck after the procedure. Due to the long-term intubation, when patients cough, the airflow carrying sputum can be sprayed directly from the tracheostomy tube, easily contaminating bed sheets, clothing, and the hands and faces of medical staff. The sprayed sputum contains a large number of bacteria and viruses, posing a significant source of nosocomial cross-infection and a threat to medical staff and immunocompromised patients.

[0003] The tracheostomy tube is directly connected to the outside world, and foreign objects such as dust and lint can easily fall into the airway, causing infection or discomfort.

[0004] Traditional solutions include: 1. Gauze covering method: Covering the catheter opening with a damp gauze to absorb sputum and prevent splashing. However, the gauze quickly becomes wet and contaminated, requiring frequent replacement and cleaning of the area around the catheter, increasing the workload of nurses. 2. Artificial nose / heat and moisture exchanger: Primarily used to humidify and warm inhaled air, it has some filtering effect, but mainly targets microbial aerosols. Its protective ability against large amounts of rapidly splashing sputum is limited, and it is easily clogged by sputum. Utility Model Content

[0005] This invention provides a tracheostomy tube protection and sputum collection device that can prevent sputum splashing, filter breathing gas, and collect sputum, thereby reducing the risk of cross-infection.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A tracheostomy tube protection and sputum collection device includes a tube fixation cover and a sputum collection bottle. The tube fixation cover is in the shape of a three-way tube. The first end is detachably connected to the tracheostomy tube, and the second end opposite to the first end has two independent interfaces, which are respectively sealed to the inlet valve and the outlet valve. Both the inlet valve and the outlet valve are equipped with a breathing filter. The third end is detachably connected to the sputum collection bottle. A guide plate is provided inside the tube fixation cover between the first end and the second end. The left and right ends of the guide plate are connected to the inner wall of the tube fixation cover, and the upper and lower ends are suspended.

[0008] Furthermore, the lower end of the guide plate is inclined toward the second end of the guide tube fixing cover, and the side of the guide plate near the first end of the guide tube fixing cover is provided with a drainage groove extending from top to bottom toward the third end of the guide tube fixing cover.

[0009] Furthermore, it also includes a cut protection component, which includes a waterproof sealing layer and an absorbent core layer. The cut protection component has a circular hole in the center that is adapted to the outer diameter of the tracheostomy tube, and a notch through the circular hole on its long side. Low-sensitivity adhesive is provided at the bottom of both ends of the waterproof sealing layer. The cut protection component is used to be sleeved on the tracheostomy tube and attached to the outer periphery of the cut.

[0010] Furthermore, the cut protection component is shaped like an arc or butterfly that conforms to the contour of the neck.

[0011] Furthermore, the waterproof sealing layer is made of medical-grade hydrolyzed adhesive or silicone gel material.

[0012] Furthermore, the absorbent core layer is made of foam or non-woven fabric material with integrated superabsorbent polymer particles.

[0013] Furthermore, a transparent film is attached to the outer surface of the absorbent core layer.

[0014] Furthermore, the absorbent core layer contains a moisture-sensitive dye that changes color when the absorbed liquid reaches a preset amount.

[0015] Furthermore, the side wall of the catheter fixation cover is provided with a suction port with a cover, and the cover and the suction port are sealed by a silicone sealing ring.

[0016] Furthermore, the bottom of the sputum collection bottle is provided with a toothed collection groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. The catheter fixing cover of this utility model is equipped with a slanted guide plate, which can block the splashed sputum and prevent it from contaminating the air inlet and outlet, while guiding the sputum to the sputum collection bottle.

[0019] 2. The sputum collection bottle of this utility model is filled with a small amount of sterile water or disinfectant for collecting and initially soaking sputum. Its bottom toothed groove structure can increase the effective contact area between sputum and sterile water or disinfectant.

[0020] 3. The waterproof sealing layer of the incision protection component of this utility model fits the skin of the neck to form a waterproof barrier, which can effectively prevent sputum, sweat and other liquids from leaking into the incision; the absorbent core layer can quickly absorb a small amount of sputum or secretions that leak from the gap between the tracheostomy tube and the waterproof sealing layer, which can prevent backflow; the transparent film not only makes it easy to observe the incision healing, but also protects the absorbent core layer from external contamination.

[0021] 4. The absorbent core contains a moisture-sensitive dye that changes color when the absorbed liquid reaches a preset amount. Medical staff can visually determine the timing of replacement through the transparent film, avoiding "over-replacement" or "delayed replacement" caused by relying on experience. This reduces the waste of medical resources and lowers the risk of incision infection. Attached Figure Description

[0031] like Figure 1 As shown, a tracheostomy tube protection and sputum collection device includes a tube fixing cover 1 and a sputum collection bottle 2. The tube fixing cover 1 is a three-way tube, with its first end 11 detachably connected to the tracheostomy tube 4, such as by a snap-fit ​​connection. A sealing ring is provided at the connection between the tube fixing cover 1 and the tracheostomy tube 4 to improve sealing. The second end 12 of the tube fixing cover 1, opposite to the first end 11, has two independent interfaces, which are respectively sealed to the inlet valve 5 and the outlet valve 6. Both the inlet valve 5 and the outlet valve 6 are equipped with breathing filters to effectively filter particulate matter and microorganisms in the inhaled air, preventing external pollutants from entering the patient's airway. At the same time, it intercepts pathogens and aerosols in the exhaled air, preventing the spread of bacteria carried by the patient to the environment and avoiding cross-infection. The filtration direction of the breathing filters matches the gas flow direction of the inlet valve 5 and the outlet valve 6. The third end 13 of the tube fixing cover is detachably connected to the sputum collection bottle 2, such as by a threaded connection. Preferably, the bottom of the sputum collection bottle 2 has a toothed collection groove 21, which can increase the effective contact area between sputum and sterile water or disinfectant, preventing drying and adhesion. The catheter fixation cover 1 has a suction port with a cap 3 on its side wall. The cap 3 and the suction port are sealed by a silicone sealing ring. Inside the catheter fixation cover 1, between the first end 11 and the second end 12, there is a guide plate 7. The left and right ends of the guide plate 7 are connected to the inner wall of the catheter fixation cover 1, and the upper and lower ends are suspended to block splashed sputum and prevent it from contaminating the air inlet and outlet. Preferably, the lower end of the guide plate 7 is inclined towards the second end 12 of the catheter fixation cover. The side of the guide plate 7 near the first end 11 of the catheter fixation cover has a drainage groove extending from top to bottom towards the third end 13 of the catheter fixation cover to guide the sputum to the sputum collection bottle 2.

[0032] like Figure 2 , Figure 3As shown, the tracheostomy catheter 4 is fitted with an incision protection component 8. The incision protection component 8 is arc-shaped or butterfly-shaped to conform to the contour of the neck and is attached to the outer periphery of the incision. The incision protection component 8 includes a waterproof sealing layer 81 and an absorbent core layer 82. The center of the incision protection component 8 has a circular hole adapted to the outer diameter of the tracheostomy catheter 4, and its long side has a notch that passes through the circular hole. The waterproof sealing layer 81 is made of medical-grade hydrolyzed adhesive or silicone gel material, and low-sensitivity adhesive is provided at both ends and the bottom. The absorbent core layer 82 is made of foam or non-woven fabric material with integrated superabsorbent polymer particles, and a transparent film 83 is attached to the outer surface. Preferably, the transparent film 83 is made of medical-grade TPU.

[0033] In some embodiments, the absorbent core layer 82 is mixed with a moisture-sensitive dye, such as bromocresol green-methyl red, which changes color (e.g., from yellow to blue) when the absorbed liquid reaches a preset amount. Medical staff can visually determine the timing of replacement through the transparent film 83, avoiding over-replacement or delayed replacement due to reliance on experience, thus reducing waste of medical resources and lowering the risk of incision infection.

[0034] In use, first clean the skin around the tracheostomy incision on the patient's neck to remove oil and sweat. Then, peel off the hypoallergenic adhesive release paper at the bottom of the waterproof sealing layer 81 of the incision protection component. Align the central hole of the component with the tracheostomy tube 4 and fit it against the neck skin, ensuring that the entire component fits perfectly against the neck contour. Next, connect the first end 11 of the tube fixation cover to the exposed end of the tracheostomy tube 4. Inject a small amount of sterile water or disinfectant into the sputum collection bottle 2, and then connect the sputum collection bottle 2 to the third end 13 of the tube fixation cover. The tube fixation cover 1 and the sputum collection bottle 2 are preferably made of transparent material to facilitate real-time observation of the amount and characteristics of sputum. When a certain amount of sputum has been collected, open the cap 3 at the suction port, insert the suction tube to suction out the sputum, and then introduce sterile water or disinfectant through the suction port to continue use. After use, the sputum collection bottle 2 can be removed and cleaned separately.

[0035] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
