Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an adjustable negative pressure drainage device fixer. Background Art

[0002] In clinical practice, negative pressure drainage devices are often connected to suction tubes to suction patients with a lot of sputum but who cannot expectorate on their own, thereby clearing the respiratory tract and improving the patient's blood oxygen partial pressure; after use, the negative pressure drainage device is disinfected and connected to an unused suction tube that has been tied to the bedside for fixation, but there is no dedicated equipment or instrument to fix the terminal pipeline of the negative pressure drainage device; the currently used fixing method is relatively simple, but there are many problems: 1. For every newly admitted patient who needs a suction tube, an unused suction tube will be used to fix the negative pressure drainage device, resulting in high medical costs; 2. For every newly admitted patient who needs a suction tube, an unused suction tube will be used to fix the negative pressure drainage device, resulting in high medical costs; 3. For every newly admitted patient who needs a suction tube, an unused suction tube will be used to fix the negative pressure drainage device, resulting in high medical costs; 4. For every newly admitted patient who needs a suction tube, an unused suction tube will be used to fix the negative pressure drainage device, resulting in high medical costs; 5. 1. The current fixing method is not convenient for the use of negative pressure drainage devices, and this method cannot be further improved when emergency situations require the time for obtaining items to be shortened as much as possible; 2. Due to the heavy clinical workload, medical staff cannot maintain sustained attention, especially for new employees who are not proficient in and do not follow standardized clinical operation procedures. Medical staff may not turn off the negative pressure device and directly place the negative pressure drainage tube next to the patient, causing the negative pressure drainage tube to continuously attract the patient's skin and mucous membranes with negative pressure, causing damage, thereby causing medical accidents. Summary of the invention

[0003] The purpose of the present invention is to solve the technical problem that there is no good fixed negative pressure drainage device at present, and to provide an adjustable negative pressure drainage device fixer. In order to solve the above technical problem, the technical solution adopted by the present invention is:

[0004] An adjustable negative pressure drainage device holder comprises a connecting portion, a coupling portion and a stretching portion, wherein one end of the coupling portion is fixedly connected to the connecting portion, and the stretching portion is inserted into the other end of the coupling portion. By configuring in this way, a pipeline at the end of the negative pressure drainage device can be better connected and fixed, thereby making it more convenient to use the negative pressure drainage device, avoiding an increase in medical costs and a waste of medical supplies, and greatly reducing the occurrence of medical accidents such as injuries to patients caused by the medical staff's own negligence.

[0005] Furthermore, the connecting part includes two No. 1 fixing clips and a cylindrical sleeve, and the two No. 1 fixing clips are symmetrically arranged on the panel of the closed end of the cylindrical sleeve. The two No. 1 fixing clips are used to fix the device to a stable position around the bed unit and can be clamped beside the patient's bed or on a treatment belt.

[0006] Furthermore, a spring is provided on the inner bottom surface of the cylindrical sleeve, so that when the device is used, when the stretching part hits the spring, it can be rebounded from the first smooth surface to the serrated surface by the spring.

[0007] Furthermore, the cylindrical sleeve and the coupling portion are threadedly connected, making disassembly and installation more convenient.

[0008] Furthermore, the cylindrical sleeve is configured as an internal thread, and the coupling portion is configured as an external thread.

[0009] Furthermore, a through hole penetrating the left and right panels is provided in the middle of the coupling part, and the inner wall of the through hole is arranged from left to right in sequence as a smooth surface No. 1, a serrated surface and a smooth surface No. 2, and a clamping ring is provided on the smooth surface No. 2. The provision of the clamping ring ensures that when the stretching part slides in the coupling part, the stretching part can be clamped by the clamping ring and will not slide out of the coupling part. If you want to adjust the angle of the stretching part, you can push the stretching part so that the serrated disk of the stretching part slides from the serrated surface to the smooth surface No. 1, and then rotate the stretching part 3 to place it in a convenient operating position (that is, the angle of the No. 2 fixing clip 302 is adjusted), loosen the stretching part 3 so that the spring 103 bounces the stretching part 3 from the smooth surface 202 to the serrated surface 203, and the serrated disk 301 is clamped by the clamping ring 205, that is, the angle adjustment of the stretching part is realized, thereby making the suction operation more convenient.

[0010] Furthermore, the stretching part includes a serrated disk and two No. 2 fixing clips, and the two No. 2 fixing clips are symmetrically arranged on one side of the serrated disk, and the serrated disk is located in the coupling part, and is used in conjunction with the serrated surface. The two No. 2 fixing clips can place the negative pressure drainage tube therein and ensure that it does not fall off and fall to the ground, preventing it from being contaminated and infecting the patient, and making the fixation of the negative pressure drainage tube more convenient and omitting cumbersome operations.

[0011] Furthermore, the sum of the height of the spring and the thickness of the serrated disk is greater than the width of the No. 1 smooth surface, and the thickness of the serrated disk is equal to the width of the serrated surface, ensuring that when the serrated disk slides to the No. 1 smooth surface, the spring has sufficient elastic force to bounce the serrated disk to the serrated surface, and when the spring is compressed to the minimum height by the serrated disk, the height of the spring and the thickness of the serrated disk are less than the width of the No. 1 smooth surface. At the same time, it also ensures that when the serrated disk is bounced to the serrated surface, the spring can also be slightly compressed by the serrated disk, so that the entire stretching part will not slide on the serrated surface.

[0012] Furthermore, the No. 1 fixing clip and the No. 2 fixing clip have the same structure, including a connecting rod and a hook. The hooks 304 of the two No. 1 fixing clips 101 and the two No. 2 fixing clips 302 in the stretching part 3 are two symmetrical semicircular rings. A rubber-like material is attached to the hooks 304 to prevent damage to the clamped objects. The bottoms of the two connecting rods 303 are each provided with a plurality of screw holes. The two No. 2 fixing clips 302 can be fixed by means of the plurality of screw holes and the serrated disk 301 (different screw holes can be selected during fixing so that the distance between the two No. 2 fixing clips 302 is different, thereby changing the size of the circular ring formed by the two hooks 304).

[0013] Furthermore, the length of the connecting rod is greater than the length of the coupling portion, ensuring that when the stretching portion slides in the coupling portion, the hook of the second fixing clip will not touch the clamping ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention comprises a connecting portion, a coupling portion and a stretching portion, and one end of the coupling portion is fixedly connected to the connecting portion, and the stretching portion is inserted into the other end of the coupling portion.

The provision of the clamping ring ensures that when the stretching part slides in the coupling part, the stretching part can be clamped by the clamping ring and will not slide out of the coupling part. If you want to adjust the angle of the stretching part, you can push the stretching part so that the serrated disk of the stretching part slides from the serrated surface to the smooth surface No. 1, and then rotate the stretching part 3 to place it in a convenient operating position (that is, adjust the angle of the No. 2 fixing clip 302), loosen the stretching part 3 so that the spring 103 bounces the stretching part 3 from the smooth surface 202 to the serrated surface 203, and the serrated disk 301 is clamped by the clamping ring 205, that is, the angle adjustment of the stretching part is realized, thereby making the suction operation more convenient.

[0019] 5. The stretching part of the present invention includes a serrated disk and two No. 2 fixing clips, the two No. 2 fixing clips are symmetrically arranged on one side of the serrated disk, and the serrated disk is located in the coupling part, and is used in conjunction with the serrated surface.
