Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a tracheotomy protector. Background Art

[0002] Clinically, there are many patients who need tracheotomy due to brain trauma, stroke, severe respiratory diseases, high paraplegia, airway burns and other diseases. Some patients with tracheotomy can be separated from the ventilator and only keep the tracheotomy airway open. In the process of clinical nursing, the tracheotomy patients are often covered with double-layer sterile moist gauze at the tracheal tube opening to protect the airway. At present, this method has the following disadvantages: 1: When the patient coughs violently, the double-layer gauze covering the tracheotomy tube opening will leave the covering part with coughing and lose its protective effect. 2: If the patient has a lot of sputum, the sputum is easy to contaminate the clothes, air, walls, ceilings, etc. when coughing, increasing the chance of cross infection. 3: Even when there is a lot of sputum, the coughed sputum may not be collected in time and is repeatedly inhaled into the lungs by the patient, greatly increasing the probability of lung infection. 4: The oxygen supply channel is not easy to access during tracheotomy. At present, it is only bonded with tape, which is not only unreliable, but also easy to contaminate. Utility Model Content

[0003] In view of the above problems, the utility model provides a tracheotomy protector which can effectively solve the above problems.

[0004] The utility model solves the technical problem by adopting the following scheme: a tracheotomy protector, which is installed on the interface of a tracheotomy cannula, and comprises a protection cavity and an upper cover, wherein the protection cavity comprises an annular bottom plate, an inner tube sleeve is arranged on the inner ring of the annular bottom plate, and the outer ring of the annular bottom plate is arranged as the outer wall of the protection cavity, wherein the inner tube sleeve is sleeved on the cannula interface, the height of the inner tube sleeve is lower than the height of the interface, an arc-shaped inclined eaves structure extending outward is arranged on the upper edge of the inner tube sleeve, the outer wall adopts a conical structure gradually expanding outward from bottom to top, and a circular extension portion is arranged on the upper side of the conical structure, the upper cover is buckled on the protection cavity through the circular extension portion, air holes are evenly arranged on the upper cover, and an oxygen interface channel is also arranged on the outer wall.

[0005] Furthermore, the upper cover is provided with an internal thread, the circular extension portion of the outer wall is provided with an external thread, and the upper cover is installed on the protective cavity through the thread structure.

[0006] Furthermore, an adhesive layer is provided on the lower side of the annular bottom plate of the protective cavity, and the protective cavity is adhered to the fixed wing of the cannula through the adhesive layer on the lower side.

[0007] Furthermore, a sealing layer is provided between the interface of the inner sleeve and the insertion tube.

[0008] Furthermore, a suction channel is also arranged on the outer wall of the protection cavity, and the suction channel is arranged on the lower side of the outer wall and close to the annular bottom plate of the protection cavity.

[0009] Beneficial effects of the utility model: the utility model clamps the inner sleeve made of medical rubber onto the joint of the tracheotomy tube, and uses the adhesive on the lower side to stick it together with the fixing wing, thereby avoiding directly covering the tube mouth of the joint with a double layer of gauze. Even if the patient coughs violently, the protector will not fall off easily and lose its protective effect.

[0010] The protector is buckled with an upper cover. Even if the patient has a lot of sputum, the sputum produced when coughing will not be reduced and cause cross infection.

[0011] The protector is equipped with a protective cavity to store sputum, and an arc-shaped inclined eaves structure is set on the inner sleeve to facilitate the coughed sputum to flow into the bottom of the protective cavity, preventing the coughed sputum from accumulating at the tracheotomy tube interface and being repeatedly inhaled into the lungs by the patient; at the same time, when the sputum flows into the bottom of the protector, the arc-shaped inclined eaves structure above the concave platform can also prevent the sputum from flowing out easily. When there is a lot of sputum, the sputum at the bottom of the protector can be sucked out through the suction channel.

[0012] The protector is provided with a standard oxygen interface channel, which can be directly connected to the oxygen supply channel, avoiding the problem of unreliable and easy contamination by adhesive tape alone. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] Embodiment 1: In the clinical nursing process, a double layer of sterile moist gauze is often used to cover the tracheotomy tube opening of a tracheotomy patient to protect the airway. This method has great defects. To address these defects and problems, the utility model provides a tracheotomy incision protector installed on a tracheotomy tube connector, such as Figure 1 and Figure 2As shown, the protector mainly includes two parts, a protection cavity 2 installed on the connector of the plug 1 and an upper cover 3 for snapping on the protection cavity 2, wherein the protection cavity 2 is an annular cavity, the outer wall 203 of the annular cavity is set to be conical, and the inner side of the annular cavity is provided with an inner sleeve 204 that can be sleeved on the plug, and the inner diameter of the inner sleeve 204 matches the outer diameter of the plug.

[0018] The bottom of the protective cavity 2 is an annular bottom plate, the inner ring of the annular bottom plate is provided with an inner tube sleeve, the outer ring of the annular bottom plate is provided with the outer wall 203 of the protective cavity 2, the inner sleeve 204 is sleeved on the interface of the cannula 1, the height of the inner sleeve 204 is lower than the height of the interface, and the upper edge of the inner sleeve 204 is provided with an outwardly extending arc-shaped slanted eaves 205 structure, the upper surface of the arc-shaped slanted eaves 205 protrudes outward, and its lower surface is concave inward, and the arc-shaped slanted eaves 205 can be provided with a hydrophobic layer to prevent sticky sputum from sticking to its surface. When the sputum produced by the patient's cough is coughed out of the cannula, the sputum will slide along the upper surface of the arc-shaped slanted eaves 205 to the bottom of the protective cavity 2, and the arc-shaped slanted eaves 205 bent downward can prevent the sputum that has been collected in the protective cavity 2 from splashing into the cannula 1 again to the greatest extent, and prevent the coughed sputum from accumulating at the interface of the tracheotomy cannula 1 and being repeatedly inhaled into the lungs by the patient.

[0019] An adhesive layer is provided on the lower side of the annular bottom plate of the protection cavity 2, and the protection cavity 2 is adhered to the fixed wing 101 of the cannula through the adhesive layer on the lower side. A sealing layer 206 is provided between the inner sleeve 204 and the interface of the cannula. The sealing layer 206 can prevent sputum from flowing out from the joint between the inner sleeve 204 and the plug, and can also increase the friction between the two through the sealing layer 206, thereby ensuring that the protector can be stably installed on the plug.

[0020] The outer wall 203 adopts a tapered structure 208 that gradually expands outward from bottom to top, and a circular extension portion is provided on the upper side of the tapered structure 208. The outer wall 203 adopts transparent medical plastic, and the inner sleeve 204 can adopt opaque flexible medical rubber and plastic. The outer wall 203 is transparent to facilitate observation of sputum collection, and the opaque inner sleeve 204 can avoid affecting the accuracy of observation. The outer wall 203 adopts a tapered structure 208 in order to increase the capacity on the basis of cooperation with the intubation fixing wing 101, that is, to make a larger accommodation space through a smaller bottom.

[0021] like Figure 3 As shown, the upper cover 3 is buckled on the protective cavity 2 through the circular extension portion 209. The upper cover 3 is composed of a plastic cover covered with gauze. The upper cover 3 is provided with an internal thread. The circular extension portion 209 of the outer wall 203 is provided with an external thread 207. The upper cover 3 is installed on the protective cavity 2 through a threaded structure. The upper cover 3 is evenly provided with air holes 301.

[0022] The outer wall 203 is also provided with an oxygen interface channel 201, which is arranged at a high position of the outer wall 203 to prevent the collected sputum from blocking the oxygen interface channel 201. At the same time, if necessary, a suction channel 202 can be further provided on the outer wall 203 of the protective cavity 2, and the suction channel 202 is arranged at the lower side of the outer wall 203 and close to the annular bottom plate of the protective cavity 2, and the collected sputum is discharged through the suction device.

[0023] The specific usage is: connect the upper cover to the protective cavity through a spiral structure. When the protective cavity is connected to the upper cover, the airflow of coughing will not blow the gauze away, so the protective effect is achieved; connect the protective cavity to the tracheotomy tube; connect the oxygen inhalation pipeline (if necessary); observe the patient's breathing and the accumulation of sputum at the bottom of the transparent protector. If there is a lot of sputum, the sputum at the bottom of the protector can be sucked out through the suction channel 202, and the protector can be replaced according to the specific situation.
