Technical Field

[0001] The present application belongs to the field of medical device technology, and specifically relates to an anesthesia gas catheter assembly. Background Art

[0002] Oral intubation is a type of endotracheal intubation, where the tube is inserted into the patient's trachea through the mouth. Oral intubation is a technique for endotracheal anesthesia and resuscitation, and is the most reliable means of maintaining upper airway patency.

[0003] The patient is older and the teeth in his mouth are prone to loosening. In addition, the tube passes through the patient's mouth, and the patient needs to keep his mouth open for a long time. The patient's teeth are tightly bitten on the first catheter. For patients with dental diseases, biting the first catheter for a long time can easily increase the patient's discomfort and cause the patient's teeth to loosen. In addition, the depth of the oral cavity of each patient is different. Therefore, when intubating, the required insertion depth of the first catheter is also different, so the position of the first catheter bitten by different patients is not fixed. Utility Model Content

[0004] In order to better protect the patient's teeth during anesthesia, reduce the damage to the patient's teeth caused by the first catheter during tracheal intubation, and ensure the patient's comfort when biting the first catheter, the present application provides an anesthesia gas catheter assembly.

[0005] A gas conduit assembly for anesthesia includes a working piece and a first conduit. The working piece includes two oppositely arranged occlusal surfaces and a working hole arranged between the two occlusal surfaces. The axis of the working hole is parallel to the occlusal surface.

[0007] In one embodiment of the present application, the extended shape of the engaging groove is an arc shape.

[0008] In one embodiment of the present application, the working piece includes an elastic sleeve arranged between two occlusal surfaces, the hole of the elastic sleeve is a working hole, and the side wall of the elastic sleeve is provided with a first notch connected to the working hole. The first notch penetrates the elastic sleeve along the axial direction of the working hole. The working piece can pass through the first notch along the radial direction of the working hole and be sleeved on the first conduit so that the working piece and the first conduit can be detachably connected.

[0009] In one embodiment of the present application, the first conduit includes a mating section, the working piece is slidably connected to the mating section, and the mating section is provided with multiple first clamping structures along its extension direction; the working piece is provided with a second clamping structure, and the second clamping structure can be connected to one of the first clamping structures.

[0010] In one embodiment of the present application, a plurality of snap-fit ​​protrusions are provided on the outer wall of the mating segment along the extension direction of the mating segment. The plurality of snap-fit ​​protrusions are arranged in an array along the extension direction of the mating segment. A snap-fit ​​groove is formed between adjacent snap-fit ​​protrusions. The snap-fit ​​groove is a first snap-fit ​​structure. The second snap-fit ​​structure is an elastic snap-fit ​​strip. The elastic snap-fit ​​strip can extend into one of the snap-fit ​​grooves to limit the movement of the working piece relative to the first conduit.

[0011] In one embodiment of the present application, the inner diameter of the working hole is equal to the outer diameter of the fitting section.

[0012] In one embodiment of the present application, a mating groove is provided on the inner wall of the working hole, the extension direction of the mating groove is parallel to the axial direction of the working hole, and the mating groove passes through the working hole along its extension direction.

[0014] In one embodiment of the present application, scales are provided on the outer side wall of the first conduit along the extension direction of the first conduit.

[0015] This application has at least the following beneficial effects:

[0016] 1. The patient's maxillary teeth and mandibular teeth can be respectively engaged on two occlusal surfaces. Both occlusal surfaces in the present application are provided with a deformable layer. The deformable layer has low-temperature thermoplasticity.

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present application, the specific implementation methods of the present application are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0028] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.

[0029] To simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled.

[0030] See Figures 1 to 5 Understand this application.

[0031] See also Figures 1 to 3 , an anesthesia gas catheter assembly, which includes a working piece 101 and a first catheter 201.

[0032] The working piece 101 includes two oppositely arranged occlusal surfaces and a working hole 102 arranged between the two occlusal surfaces. The axis of the working hole 102 is parallel to the occlusal surfaces. The working piece 101 is sleeved on the first catheter 201 through the working hole 102 and is slidably connected to the first catheter 201. The working piece 101 and the first catheter 201 are detachably connected. When in use, medical staff can first insert the first catheter 201 into the patient's trachea or bronchus so that the first catheter 201 is in a suitable position, and then connect the working piece 101 to the first catheter 201, and make the working piece 101 slide along the first catheter 201, adjust the working piece 101 to a suitable position, and facilitate the patient to bite the working piece 101.

[0033] Those skilled in the art of the present application will understand that there are many ways to achieve the detachable connection between the working piece 101 and the first conduit 201. For example, in one embodiment of the present application, the working piece 101 includes an elastic sleeve provided between two occlusal surfaces, the working hole 102 is provided in the elastic sleeve, the hole of the elastic sleeve is the working hole 102, and the side wall of the elastic sleeve is provided with a first notch 106 communicating with the working hole 102. The first notch 106 penetrates the working piece elastic sleeve along the axial direction of the working hole 102. The working piece 101 can be sleeved on the first conduit 201 along the radial direction of the working hole 102 through the first notch 106 that undergoes elastic deformation. So that the working piece 101 and the first catheter 201 are detachably connected, when the patient bites the working piece 101, the maxillary teeth can bite on one of the occlusal surfaces, and the mandibular teeth can bite on the other occlusal surface, thereby limiting the opening of the first notch 106, and preventing the first catheter 201 from leaving the working hole 102 through the first notch 106 when the patient bites the working piece 101. When the first notch 106 undergoes elastic deformation, the first notch 106 opens, and the first catheter 201 can leave the working hole 102 through the first notch 106. The working piece 101 is separated from the first catheter 201, which facilitates the subsequent withdrawal of the first catheter 201 by medical staff.

[0034] Of course, there are other ways to achieve detachable connection between the working piece 101 and the first conduit 201. For example, when one end of the first conduit 201 is not connected to other devices or components, one end of the first conduit 201 can be inserted into or removed from the working hole 102. This will not be repeated here.

[0035] The two occlusal surfaces of the working piece 101 are arranged relative to the working hole 102. The occlusal surfaces are provided with a deformable layer 104. The deformable layer 104 has low-temperature thermoplasticity, thereby connecting the heated working piece 101 to the first conduit 201. When the patient bites the working piece 101, the heated and softened deformable layer 104 can fit the patient's teeth and the shape of the patient's dental arch, adapting to the patient's tooth arrangement, preventing the working piece 101 from damaging the patient's teeth. At the same time, it ensures that the patient can firmly bite the working piece 101 and prevent the working piece 101 from falling off. Those skilled in the art of the present application will understand that the deformable layer 104 in the present application can be made of materials such as polycaprolactone.

[0036] In one embodiment of the present application, the occlusal surface is provided with an occlusal groove 103, which penetrates the occlusal surface along the extension direction of the occlusal surface. A deformation layer 104 is provided in the occlusal groove 103, so that when the teeth extend into the occlusal groove 103 and squeeze the deformation layer 104, the occlusal groove 103 can limit the deformation of the deformation layer 104, thereby preventing the deformation layer 104 from dispersing to the surroundings and causing uncontrollable deformation.

[0037] In one embodiment of the present application, the extended shape of the occlusal groove 103 is arc-shaped, so that the extension direction of the occlusal groove 103 can fit the shape of the dental arch, thereby improving the patient's comfort. When the patient's teeth extend into the occlusal groove 103, the teeth can limit the movement of the working piece 101 relative to the teeth through the occlusal groove 103, thereby improving the stability of the working piece 101 in the oral cavity, and further improving the stability of the first catheter 201 connected to the working piece 101, thereby preventing the first catheter 201 from leaving the appropriate intubation position.

[0038] In one embodiment of the present application, the first conduit 201 includes a mating section, the working piece 101 is slidably connected to the mating section, and the mating section is provided with multiple first clamping structures along its extension direction; the working piece 101 is provided with a second clamping structure, and the second clamping structure can be connected to one of the first clamping structures.

[0039] See also Figure 1 、 Figure 4 、 Figure 5In an embodiment of the present application, the outer wall of the fitting section is provided with a plurality of clamping protrusions 202 along the extending direction of the fitting section, the plurality of clamping protrusions 202 are arranged along the extending direction of the fitting section, and a clamping groove 203 is formed between adjacent clamping protrusions 202, the clamping groove 203 being a first clamping structure; a second clamping structure is an elastic clamping strip 105, the elastic clamping strip 105 being capable of extending into one of the clamping grooves 203 to limit the movement of the working piece 101 relative to the first conduit 201, so that when the working piece 101 moves along the first conduit 201, the elastic clamping strip 105 can elastically deform to leave the movement path of the working piece 101 relative to the clamping protrusions 202, and after the working piece 101 is located at a proper position relative to the first conduit 201, the clamping protrusions 202 are inserted into the clamping grooves 203 to lock the position of the working piece 101 relative to the first conduit 201 through the first clamping structure and the second clamping structure, so that the patient can lock the position of the first conduit 201 through the working piece 101 to avoid the movement of the first conduit 201 relative to the working hole 102.

[0040] In an embodiment of the present application, the inner diameter of the working hole 102 is equal to the outer diameter of the fitting section, and the outer wall of the first conduit 201 can be attached to the inner wall of the working hole 102 to facilitate the patient to hold the working piece 101 and limit the position of the first conduit 201 through the working piece 101.

[0041] Referring to Figure 2 In an embodiment of the present application, the inner wall of the working hole 102 is provided with a fitting groove 107, the extending direction of the fitting groove 107 being parallel to the axial direction of the working hole 102, and the fitting groove 107 extends through the working hole 102 along the extending direction thereof, so that when the working piece 101 moves relative to the fitting section, the clamping protrusions 202 can pass through the fitting groove 107 to avoid the collision between the clamping protrusions 202 and the hole opening of the working hole 102 when the working piece 101 slides along the first conduit 201, thereby limiting the movement of the working piece 101.

[0042] In an embodiment of the present application, the length of the clamping groove 203 is less than the length of the fitting groove 107, which facilitates the locking of the stability of the first conduit 201 relative to the working piece 101 through the elastic clamping strip 105 and the working hole 102, and at the same time, ensures that the clamping protrusions 202 are always located in the fitting groove 107 to limit the rotation of the first conduit 201 relative to the working hole 102, thereby facilitating the stability of the first conduit 201.

[0043] Those skilled in the art to which the present application pertains can understand that the first clamping structure and the second clamping structure in the present application also have other implementation manners, such as the first clamping structure being the elastic clamping strip 105 and the second clamping structure being the clamping groove 203, and of course, there are other implementation manners, which are not described herein.

[0044] Referring to Figure 1In one embodiment of the present application, a scale 204 is provided on the outer wall of the first catheter 201 along the extension direction of the first catheter 201 to facilitate medical staff to understand the insertion depth of the first catheter 201.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
