Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a gastric tube fixer. Background Art

[0002] Clinically, all patients who cannot take food through the mouth need to have a gastric tube inserted, through which food and medicine are injected. In addition, patients with gastrointestinal obstruction caused by various reasons and patients undergoing gastric and esophageal surgery also need to have a gastric tube inserted for gastrointestinal decompression. The conventional method of fixing the gastric tube is to fix it on the cheeks and wings of the nose with adhesive tape. The adhesive tape is attached to the skin. Due to the high secretion of oil and sweat glands in the cheeks and wings of the nose, the adhesive tape is not firmly fixed and the gastric tube falls off. Conventional adhesive tape fixation requires repeated replacement of the tape. During the replacement process, the risk of accidental tube dislocation is increased, which brings troubles to caregivers and patients.

[0003] Therefore, a stomach tube fixer is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a gastric tube fixator to improve the stability of gastric tube fixation, reduce the probability of falling off, and avoid the discomfort caused to the patient by secondary or multiple intubations.

[0005] In order to solve the above technical problems, the utility model provides a gastric tube fixer, comprising a fitting block with a through hole on the outer facade, a limiting cylinder, a plastic clamping part and a sliding cylinder;

[0006] The fitting block is used to fit the philtrum of the patient and can be kept relatively fixed with the patient;

[0007] The limiting cylinder is arranged on the fitting block and communicated with the through hole;

[0008] The plastic clamping portion is annularly arranged on an end surface of the limiting cylinder away from the bonding block;

[0009] When the outer wall of the plastic clamping portion is squeezed by an external force, it can be deformed along the axial centerline direction of the limiting cylinder;

[0010] The sliding cylinder is slidably mounted on the outside of the limiting cylinder and can be relatively fixed with the limiting cylinder;

[0011] A truncated cone-shaped cavity for contacting the outer walls of the plurality of plastic clamping parts is arranged inside the sliding cylinder.

[0012] Furthermore, when the sliding cylinder slides in a direction close to the limiting cylinder, the inner wall of the truncated cone-shaped chamber can synchronously extrude the plurality of plastic clamping parts, so that the plurality of plastic clamping parts are deformed and offset along the axial direction of the limiting cylinder.

[0013] Furthermore, the inner diameter of the truncated cone-shaped chamber decreases gradually in a direction away from the limiting cylinder.

[0014] Furthermore, the minimum inner diameter of the truncated cone-shaped chamber is greater than the outer diameter of the gastric tube.

[0015] Furthermore, one end of the plastic clamping portion in contact with the truncated cone-shaped cavity is configured as a wedge-shaped structure.

[0016] Further, the sliding cylinder includes a cylinder body and a threaded ring;

[0017] The cylinder body is slidably plugged into the limiting cylinder;

[0018] The threaded ring is threadedly connected to the cylinder body and is threadedly connected to the outer wall of the limiting cylinder.

[0019] Furthermore, straps for connecting to the patient's ears are provided on both sides of the fitting block.

[0020] Furthermore, the fitting block is configured as an L-shaped structure;

[0021] The side of the fitting block that fits the philtrum of the patient is arranged in an arc shape.

[0022] Furthermore, the plastic clamping portion is made of plastic material.

[0023] Compared with the prior art, the utility model has at least the following beneficial effects:

[0024] By providing a fitting block, a limiting cylinder, a plastic clamping portion and a sliding cylinder that fit with the philtrum of the patient and can be relatively fixed, since the limiting cylinder is connected to the through hole of the fitting block, the gastric tube can pass through the limiting cylinder and the through hole in sequence to enter the patient's stomach, and then the truncated cone chamber provided in the sliding cylinder is used to make the sliding cylinder move relative to the limiting cylinder, and the plastic clamping portion is pulled to deform, so as to complete the clamping of the outer wall of the gastric tube, thereby achieving the locking of the gastric tube. Therefore, compared with the method of binding with adhesive tape in the prior art, the probability of the gastric tube falling off can be effectively reduced, so as to achieve the purpose of improving the stability of gastric tube fixation. In addition, it can also effectively avoid the discomfort caused to the patient by reinserting the gastric tube for two or more times. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The stomach tube fixer of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the present invention.

[0030] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0031] like Figures 1 to 3 As shown, an embodiment of the utility model provides a gastric tube fixer, comprising a fitting block 1 with a through hole 11 on the outer facade, a limiting cylinder 2, a plastic clamping portion 3 and a sliding cylinder 4.

[0032] The fitting block 1 is used to fit the philtrum of the patient and can remain relatively fixed to the patient, that is, the fitting block 1 serves as a supporting carrier so that the subsequent limiting cylinder 2 can remain relatively fixed to the patient during installation.

[0033] Specifically, straps 5 for connecting to the patient's ears are provided on both sides of the fitting block 1. By providing the straps 5 on the fitting block 1, the patient's ears and philtrum can be surrounded to form a triangular stable support area, so that when the gastric tube is inserted into the through hole 11, the gastric tube will not be detached due to the movement of the fitting block 1.

[0034] The limiting tube 2 is arranged on the fitting block 1 and is communicated with the through hole 11, that is, the gastric tube can pass through the limiting tube 2 and the through hole 11 in sequence and enter the human stomach.

[0035] The plastic clamping portion 3 is annularly arranged on the end surface of the limiting tube 2 away from the bonding block 1, and is used to limit and clamp the gastric tube so that the gastric tube cannot be easily pulled out, thereby effectively avoiding the occurrence of secondary or multiple intubations.

[0036] It should be noted that when the outer wall of the plastic clamping part 3 is squeezed by external force, it can be deformed along the axis of the limiting tube 2. Therefore, when multiple plastic clamping parts 3 are deformed synchronously along the axis of the limiting tube 2, the stomach tube can be clamped and fixed. The plastic clamping part 3 is made of plastic material, which is convenient for the plastic clamping part 3 to deform and clamp the stomach tube.

[0037] The sliding cylinder 4 is slidably mounted on the outside of the limiting cylinder 2 and can be relatively fixed with the limiting cylinder 2 .

[0038] The interior of the sliding cylinder 4 is provided with a truncated cone-shaped chamber 411 for contacting the outer walls of the plurality of plastic clamping parts 3. When the sliding cylinder 4 slides in a direction close to the limiting cylinder 2, the inner wall of the truncated cone-shaped chamber 411 can synchronously squeeze the plurality of plastic clamping parts 3, so that the plurality of plastic clamping parts 3 are deformed and offset along the axial direction of the limiting cylinder 2, thereby completing the clamping and limiting of the gastric tube.

[0039] In order to conveniently describe the operating principle of the device, a method for using the gastric tube fixator is also proposed, comprising the following steps:

[0040] First, place the fitting block 1 on the philtrum of the patient, and lock the fitting block 1 with the bandage 5;

[0041] Then the sliding cylinder 4 is sleeved on the outside of the limiting cylinder 2, and the truncated cone-shaped cavity 411 is not squeezed by the plastic clamping part 3;

[0042] Then, the stomach tube is passed through the sliding cylinder 4, the limiting cylinder 2 and the through hole 11 in sequence to enter the patient's stomach;

[0043] Then, the sliding cylinder 4 is moved again, so that the truncated cone-shaped chamber 411 presses against the outer wall of the plastic clamping part 3 to clamp the gastric tube;

[0044] Finally, the sliding cylinder 4 and the limiting cylinder 2 are kept relatively fixed to ensure the clamping of the gastric tube.

[0045] The device is provided with a fitting block 1, a limiting cylinder 2, a plastic clamping portion 3 and a sliding cylinder 4 which fit the philtrum of the patient and can be relatively fixed. Since the limiting cylinder 2 is connected to the through hole 11 of the fitting block 1, the gastric tube can pass through the limiting cylinder 2 and the through hole 11 in sequence to enter the patient's stomach, and then the truncated cone chamber 411 provided in the sliding cylinder 4 is used to make the sliding cylinder 4 pull the plastic clamping portion 3 to deform during the movement relative to the limiting cylinder 2, thereby completing the clamping of the outer wall of the gastric tube, thereby achieving the locking of the gastric tube. Therefore, compared with the method of binding with adhesive tape in the prior art, the probability of the gastric tube falling off can be effectively reduced, thereby achieving the purpose of improving the stability of the gastric tube fixation. In addition, it can also effectively avoid the discomfort caused to the patient by reinserting the gastric tube for two or more times.

[0046] It should be noted that the inner diameter of the truncated cone chamber 411 decreases in a direction away from the limiting cylinder 2, so that when the sliding cylinder 4 gradually feeds in a direction close to the limiting cylinder 2, the inner wall of the truncated cone chamber 411 can squeeze the plastic clamping portion 3 to deflect (such as Figure 3 shown).

[0047] It should also be noted that the end of the plastic clamping part 3 that contacts the truncated cone-shaped chamber 411 is configured as a wedge-shaped structure, and the wedge-shaped surface matches the inner wall of the truncated cone-shaped chamber 411, so as to prevent the plastic clamping part 3 from breaking due to hard contact during the docking process between the truncated cone-shaped chamber 411 and the plastic clamping part 3, thereby improving the stability of the device operation.

[0048] In addition, the minimum inner diameter of the truncated cone chamber 411 is set to be larger than the outer diameter of the gastric tube to avoid jamming of the gastric tube due to interference from the inner wall of the truncated cone chamber 411 when the gastric tube passes through the sliding cylinder 4, the limiting cylinder 2 and the through hole 11 in sequence.

[0049] In other embodiments, a specific sliding cylinder 4 is also provided to better achieve the control and self-locking of the plastic clamping portion 3 .

[0050] Specifically, the sliding cylinder 4 includes a cylinder body 41 and a threaded ring 42 .

[0051] The cylinder 41 is slidably plugged into the limiting cylinder 2 , and the truncated cone-shaped chamber 411 is disposed on the inner wall of the cylinder 41 .

[0052] Among them, the threaded ring 42 is threadedly connected to the cylinder 41 and to the outer wall of the limiting cylinder 2. When the cylinder 41 slides to a specified position (such as when the truncated cone chamber 411 squeezes multiple plastic clamping parts 3 and completes the fixation of the gastric tube), the threaded relationship between the threaded ring 42 and the cylinder 41 is utilized to prevent the cylinder 41 from moving relative to the limiting cylinder 2, so as to achieve the limitation of the cylinder 41 and ensure the clamping effect of the plastic clamping part 3 on the gastric tube.

[0053] In other embodiments, the fitting block 1 is also configured as an L-shaped structure so that a gap is reserved between the patient's nose and the fitting block 1 to ensure that the patient's breathing is not disturbed.

[0054] In addition, the side of the fitting block 1 that fits the philtrum of the patient is configured to be arc-shaped, thereby improving the fitting effect and reducing the patient's discomfort.

[0055] Preferably, a rubber pad is provided on the side of the fitting block 1 that fits the philtrum of the patient to further improve comfort.

[0056] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
