Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an improved fixing device for a gastric lavage tube bite mouth. Background Art

[0002] Gastric lavage refers to pouring a certain component of liquid into the gastric cavity, mixing the gastric contents and then pumping them out. This process is repeated many times. The purpose is to remove the unabsorbed poisons in the stomach or clean the gastric cavity, and it is clinically used for preoperative preparation of gastric surgery and examinations. In the treatment of emergency gastric lavage patients, it is often necessary to install a bite mouth when inserting a gastric lavage tube through the mouth to prevent the patient from biting the gastric tube, which may cause blockage of the gastric tube, resulting in unsmooth gastric lavage or even asphyxia. Currently, the common medical bite mouth is a rubber sleeve with a simple structure, general fixation and adaptability to the gastric tube, and it is easy to be bitten or fall off due to mismatch.

[0005] An improved fixing device for a gastric lavage tube bite mouth includes an outer support ring, a gastric tube fixing ring and an elastic rope. The gastric tube fixing ring is arranged inside the outer support ring. The gastric tube fixing ring is composed of two upper and lower half rings. Each half ring is provided with a movable rod and a buffer plate on both sides. One end of the movable rod is hinged to the top of the half ring, and the other end is slidably connected to the buffer plate. The end of the buffer plate far from the half ring is connected to the outer support ring and is provided with a locking block. A spring is connected between the two corresponding buffer plates. The two ends of the elastic rope are respectively connected to both sides of the outer support ring close to the buffer plate.

[0006] Further, a plurality of springs are evenly distributed between the two buffer plates.

[0007] Further, the outer support ring is made of an elastic material.

[0008] Further, a rubber pad is arranged on the inner side of the gastric tube fixing ring.

[0009] Further, a chute is arranged on the buffer plate, and a locking head cooperating with the locking block is arranged at one end of the movable rod slidably connected to the chute.

[0010] Further, the two upper and lower half rings are in a separated state.

[0011] Further, the inner side of the half ring is arc-shaped.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model fixes the gastric tube by means of bite force and has a buffer structure, which can buffer part of the bite force after fixing the gastric tube, so that the bite mouth and the gastric tube are not easily bitten and damaged. Brief Description of the Drawings

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Generally, the components of the embodiments of the present application described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0019] In the description of the embodiments of the present application, it should be noted that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of this application is normally placed, or the orientation or positional relationship commonly understood by those skilled in the art. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present application.

[0020] In the description of the embodiments of the present application, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0021] Such as Figure 1As shown in the figure, an improved bite mouth fixing device for a gastric lavage tube includes an outer support ring 1, a gastric tube fixing ring, and an elastic cord 3. The gastric tube fixing ring is arranged inside the outer support ring 1. The gastric tube fixing ring is composed of two semi-rings 2 in a separated state up and down. The inner side of the semi-ring 2 is arc-shaped. On both sides of each semi-ring 2, there are movable rods 4 and buffer plates 5. One end of the movable rod 4 is hinged to the top of the semi-ring 2, and the other end is slidably connected to the buffer plate 5. The end of the buffer plate 5 away from the semi-ring 2 is connected to the outer support ring 1, and there is a chute on it. The end of the movable rod 4 slidably connected to the chute is provided with a locking head that cooperates with the locking block 6. A plurality of springs 7 are evenly distributed between the upper and lower corresponding buffer plates 5. As Figure 2 shown in the figure, when the fixing device is sleeved on the gastric tube 8, the patient bites the outer support ring 1 under the stimulation of the gastric tube 8. After the outer support ring 1 is compressed by the biting force, the two semi-rings 2 in the middle move relatively to clamp the gastric tube 8. A rubber pad is provided on the inner side of the gastric tube fixing ring, which can increase the friction between the gastric tube 8 and the gastric tube fixing ring. The movement of the semi-ring 2 will drive one end of the movable rod 4 to move along the chute on the buffer plate 5 to both sides until the locking head is clamped into the locking block 6, and the two semi-rings 2 just clamp and fix the gastric tube 8. When it is necessary to loosen the gastric tube 8 later, the clamping of the gastric tube fixing ring can be released by directly breaking the movable rod 4 or pulling the locking head out of the locking block 6.

[0022] The outer support ring 1 is made of an elastic material and is hollow inside. It has a certain elasticity itself, so that the patient has a certain biting buffer space when biting the outer support ring 1, avoiding biting the outer support ring 1 damaged. In addition, the springs 7 arranged between the buffer plates 5 can also play a buffering role to buffer the pressure brought by the bite to the gastric tube 8.

[0023] Both ends of the elastic cord 3 are respectively connected to both sides of the outer support ring 1 close to the buffer plate 5. The elastic cord 3 is sleeved on the patient's head to fix the whole device.

[0024] Certainly, the present utility model can also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and deformations according to the present utility model, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present utility model.
