DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Embodiment 1:

[0028] The technical problem addressed by this embodiment is as shown in the background technology: since there is no protective device on the outside of the gastric lavage tube 2, when it is in the oral position, the patient's mouth is easily closed, which causes the gastric tube to be compressed, causing deformation of the tube body, which is easy to affect injection or cause reflux;

[0029] In order to solve this technical problem, the present embodiment provides a gastric lavage device, which provides an anti-bite fixed expansion component 4 on the outside of the gastric lavage tube 2 to provide corresponding oral support according to the needs of different patients. It not only avoids the gastric lavage tube 2 from being crushed during the oral closure process, but also makes it easy to maintain the oral cavity open, thereby facilitating gastric lavage.

[0030] Reference Figure 1 and Figure 4 A gastric lavage device comprises a gastric lavage syringe 1 and a gastric lavage tube 2, and also comprises a firm fitting component 3 and an anti-bite fixed expansion component 4. One end of the gastric lavage tube 2 is provided with a firm fitting component 3, the gastric lavage tube 2 is connected to the gastric lavage syringe 1 through the firm fitting component 3, and the outer side of the gastric lavage tube 2 is slidably connected with the anti-bite fixed expansion component 4;

[0031] The gastric lavage tube 2 includes a sliding sleeve 10, a carrying box 11, an elastic support member and a contact support plate 17. The outer side of the gastric lavage tube 2 is slidably connected to the sliding sleeve 10, the top and bottom ends of the sliding sleeve 10 are fixedly connected to the carrying box 11, the inner side of the carrying box 11 is provided with an elastic support member, and the top end of the elastic support member is fixedly connected to the contact support plate 17.

[0032] The elastic support member includes a light rod 12, a guide slider 13, a spring 14, a force unloading push rod 15 and a separation pressure block 16. The light rod 12 is fixedly connected to both sides of the carrying box 11, and both ends of the light rod 12 are slidably connected to the guide slider 13. One end of the guide slider 13 is fixedly connected to the spring 14, and the end of the spring 14 away from the guide slider 13 is fixedly connected to the carrying box 11. The lateral rotation of the guide slider 13 is connected to the force unloading push rod 15, and the top end of the force unloading push rod 15 is rotationally connected to the separation pressure block 16.

[0033] The top end of the separation pressing block 16 is fixedly connected to the contact support plate 17 .

[0034] A medical silicone pad is provided on the top of the contact support plate 17 .

[0035] Before use, the gastric lavage tube 2, the firm fitting component 3 and the anti-bite fixed expansion component 4 should all be placed in a dust-free and sterile protective bag and taken out when in use. The anti-bite fixed expansion component 4 can be disinfected and sterilized in the same way as medical forceps and the same way as the oral components removed by the patient. The firm fitting component 3, the gastric lavage tube 2 and the gastric lavage syringe 1 are all disposable items.

[0036] During use, the gastric lavage syringe 1 and the gastric lavage tube 2 are assembled and connected by the stable fitting component 3, the anti-bite fixed expansion component 4 is sleeved on the outside of the gastric lavage tube 2, and the sliding sleeve 10 slides on the outside of the gastric lavage tube 2, so that the anti-bite fixed expansion component 4 slides to a suitable position as a whole, so that the anti-bite fixed expansion component 4 is in a closed position of the oral cavity;

[0037] At this time, the patient's upper and lower teeth respectively contact the contact support plate 17, avoiding direct contact with the gastric lavage tube 2. When the patient wants to move the oral muscles, the force in the upper and lower closing process is transmitted to the separation pressure block 16 through the contact support plate 17. The separation pressure block 16 is used to distribute the force to the unloading push rod 15. The force is squeezed to the distribution slide block 13 through the folding distribution of the unloading push rod 15. The distribution slide block 13 slides on the outside of the light rod 12 to distribute the force to the spring 14, forming a divided force unloading. In this way, the comfort of use is improved.

[0038] Embodiment 2:

[0039] This embodiment further improves the connection stability between the gastric lavage syringe 1 and the gastric lavage tube 2 by adding a stable fitting component 3 at the connection position between the original gastric lavage syringe 1 and the gastric lavage tube 2, improves the anti-separation stability during the gastric lavage process, and avoids accidental separation.

[0040] See also Figure 1 - Figure 3The stable fitting assembly 3 includes a connecting sleeve 5, an outer ring sleeve 6, a rotating plate 7, a threaded rod 8 and a pressing plate 9. One end of the gastric lavage tube 2 is fixedly connected to the connecting sleeve 5. A fitting hole is opened at one end of the connecting sleeve 5. The outer side of the connecting sleeve 5 is fixedly connected to the outer ring sleeve 6. The inner side of the outer ring sleeve 6 is connected to the threaded rod 8 through threads. The top end of the threaded rod 8 is fixedly connected to the rotating plate 7. The bottom end of the threaded rod 8 is rotatably connected to the pressing plate 9.

[0041] A medical silicone ring is arranged on the inner side of the fitting hole.

[0042] In order to further reduce economic expenditure, in different embodiments, the outer ring plate 6, the rotating plate 7, the threaded rod 8 and the clamping plate 9 can be processed by 3D printing.

[0043] The gastric lavage syringe 1 is inserted into the inner side of the fitting hole, and a medical silicone ring is used to provide better friction for the insertion connection. After the connection, the rotating plate 7 is rotated to drive the threaded rod 8 to complete the rotation. The rotation of the threaded rod 8 causes the clamping plate 9 to descend, and the outer side of the connection position is clamped, thereby achieving a better fastening effect.
