Description

Technical Field

[0001] The utility model belongs to the technical field of medical suction equipment, and in particular relates to a closed sputum suction tube which is easy to operate. Background Art

[0002] The function of the suction tube is to clear the sputum or viscous secretions in the patient's respiratory tract or chest cavity. The principle of suction is to suck out the patient's sputum or viscous secretions through the suction tube by means of a negative pressure device or the like, thereby ensuring the patency of the patient's respiratory tract and facilitating the treatment of the patient. Among the medical supplies currently used for clearing respiratory secretions, the main one used is a closed suction tube. With this treatment method, the entire suction operation can be carried out in a relatively closed space, which can effectively avoid cross infection between the patient's respiratory tract and medical staff. During operation, the suction tube needs to be inserted into or withdrawn from the patient's respiratory tract. However, the existing closed suction tube directly operates the suction tube across the entire film. Since the contact surfaces between the suction tube and the film are relatively smooth, when the suction tube is inserted into or withdrawn, the suction tube is prone to relative sliding with the film, affecting the operation. Therefore, in response to the above problems, we propose a closed suction tube that is easy to operate. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model will be further described below in conjunction with the accompanying drawings.

[0027] Reference Figure 1-Figure 6 As shown, the embodiment of the present invention is a closed type sputum suction tube which is easy to operate, and comprises a first joint assembly 1, a second joint assembly 2, a sputum suction tube 3, a film sleeve 4 and a friction assembly 5.

[0028] In this embodiment, the first joint assembly 1 specifically includes a first mounting seat 11, a suction tube connecting pipe 12 and a suction control valve 13. The rear end of the suction tube 3 is fixedly connected to the front end of the first mounting seat 11. The suction tube connecting pipe 12 is fixedly connected to the rear end of the first mounting seat 11 and is connected to the suction tube 3. The suction control valve 13 is arranged on the suction tube connecting pipe 12, and the rear end of the film sleeve 4 is fixedly connected to the front end of the first mounting seat 11.

[0029] In this embodiment, the second joint assembly 2 specifically includes a second mounting seat 21, a trachea connecting tube 22 and a ventilator connecting tube 23. The second mounting seat 21 is provided with a through groove for the suction tube 3 to pass through. The trachea connecting tube 22 is fixedly connected to the front end of the second mounting seat 21, the front end of the film sleeve 4 is fixedly connected to the rear end of the second mounting seat 21, and the ventilator connecting tube 23 is connected and communicated with the trachea connecting tube 22.

[0030] The structures shown in the above two joint assemblies are presented as specific structures of the two joint assemblies, and their functions and usages are consistent with the functions and usages of the corresponding structures of the closed sputum suction tube in the prior art, and will not be repeated here.

[0031] In this embodiment, there are at least two friction components 5. The friction components 5 specifically include a friction member 51 and a control member 52. The friction member 51 and the control member 52 are respectively located on the inner and outer sides of the film sleeve 4, and the friction member 51 is magnetically fixed to the control member 52 through the film sleeve 4, so that the friction component 5 and the film sleeve 4 can be fixed. The two friction components 5 can be respectively fixed to the upper and lower sides of the film sleeve 4 on the sputum suction tube 3, so that the sputum suction tube 3 can be clamped by the two friction components 5 through the film sleeve 4.

[0032] In this embodiment, a plurality of protrusions 512 are evenly arranged on the side of the friction member 51 away from the control member 52, and the friction member 51 is made of silicone material. This arrangement is to increase the roughness of the surface of the friction member 51 so that the friction member 51 and the suction tube 3 can be in stable contact.

[0033] When pumping the suction tube 3 through the film sleeve 4, the medical staff can control the two friction members 51 located on the inner side of the film sleeve 4 to clamp the suction tube 3 through the two control members 52 located on the outer side of the film sleeve 4, and then drive the suction tube 3 to be pumped in this clamping manner. Since the friction coefficient between the friction member 51 and the suction tube 3 is greater than the friction coefficient between the film sleeve 4 and the suction tube 3, the friction member 51 and the suction tube 3 can maintain stable contact, thereby preventing the two from sliding, so that the medical staff can stably pump the suction tube 3.

[0034] It is worth mentioning that this solution will not change the structural shape of the various parts of the closed sputum suction tube in the prior art, so the various parts can still be produced using conventional production methods.

[0035] Further, in this embodiment, a finger ring buckle 521 is fixedly connected to the side of the control member 52. The finger ring buckle 521 is provided so that the user can insert a finger so that the control member 52 can be worn on the finger of the medical staff, so that the medical staff can control the control member 52 to move.

[0036] Furthermore, in this embodiment, a friction member receiving groove 522 is provided on the side of the control member 52, and the friction member 51 is magnetically fixed in the friction member receiving groove 522 via the film sleeve 4. The cross-sectional shape of the friction member 51 is circular, the shape of the friction member receiving groove 522 matches the shape of the friction member 51, and the axial length of the friction member 51 is greater than or equal to the depth of the friction member receiving groove 522. This arrangement allows the friction member 51 and the control member 52 to clamp the film sleeve 4 more stably, and at the same time can prevent the friction member 51 and the control member 52 from sliding relative to each other in the lateral direction.

[0037] Furthermore, in this embodiment, a magnet is provided at the bottom of the friction member receiving groove 522, and an iron sheet is provided on the side of the friction member 51 close to the control member 52, so that the friction member 51 can be adsorbed and fixed in the friction member receiving groove 522. In addition, in other embodiments, an iron sheet can be provided at the bottom of the friction member receiving groove 522, and a magnet can be provided on the side of the friction member 51 close to the control member 52, so that the friction member 51 can be adsorbed and fixed in the friction member receiving groove 522.

[0038] In summary, the utility model discloses a closed suction tube that is easy to operate. A friction component that can stably hold the suction tube is arranged on the film sleeve of the closed suction tube. Holding the suction tube by the friction component can prevent the suction tube from sliding, so that medical staff can stably pump the suction tube.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
