Description

Technical Field

[0001] The utility model relates to a hemodialysis auxiliary accessory, in particular to a hemodialysis pipeline fixer. Background Art

[0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and the electrolyte solution (dialysate) containing similar concentrations to the body are exchanged through diffusion / convection inside and outside the hollow fibers to remove metabolic wastes, maintain electrolyte and acid-base balance, remove excess water from the body, and return the purified blood. The whole process is called hemodialysis.

[0003] During hemodialysis, see Figure 7 As shown, blood flows out to the dialyzer through one tube, and the blood after dialyzation by the dialyzer flows back into the patient's body through another tube; in the actual puncture process, the puncture point is located on the patient's arm, but in the actual dialysis process, the puncture point uses tape to fix the needle. However, if the patient's arm moves, the two tubes swing. At this time, the needle is easily removed from the patient's arm under the drive of the two tubes, posing a safety hazard. Utility Model Content

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figure 1-Figure 7 The present application provides a hemodialysis tubing fixer, comprising: a base and a connector; the base is used to connect to the patient's top, and the connector is plug-connected to the base; at least two annular buckles are arranged on the connector, one of the buckles is used to fix the inflow pipeline of the hemodialysis pipeline, and the other buckle is used to fix the outflow pipeline of the hemodialysis pipeline.

[0025] In this embodiment, the base can be made of hard silicone material, which is convenient for disinfection of the base. Of course, the connector can also be made of hard silicone material, which is convenient for disinfection of the connector. The base can be connected to the patient's top in the following ways: a Velcro surface is provided on the shoulder of the patient's top, a Velcro is provided on the back of the base, and the base is directly installed on the shoulder of the patient's top by Velcro bonding; or a through hole is provided on the bottom side of the base, and the base is directly sewn to the patient's top with needle and thread; of course, other ways can also be used, such as pinning the base to the patient's top with a pin, etc. This application does not limit the connection method between the base and the patient's top.

[0026] In this embodiment, the connector and the base can be connected by opening a limit groove on the base and directly inserting the connector into the limit groove. The cross-sectional shape of the limit groove can be regular or irregular. Correspondingly, the shape of the connector is adapted to the shape of the limit groove, so that the connector can be inserted into the limit groove, so that the connector and the base can be snap-fitted and assembled.

[0027] In this embodiment, the present application does not limit the number of annular buckles, and the shape of the annular buckles can be as follows: Figure 3 The shape shown is a semi-open annular structure. During the assembly process, the hemodialysis tubing can be crimped into the annular buckle, which is simple to operate and easy to use.

[0028] During use, the base is fixed on the patient's shirt, and then the connector is clipped into the base, and the inlet pipe of the dialysis pipeline is fixed on one buckle, and the outlet pipe of the dialysis pipeline is fixed on another buckle. There is a certain distance between the fixed position of the buckle and the needle at the patient's puncture point. At this time, the pipeline between the buckle and the patient's puncture point will be fixed relative to the patient's arm. At this time, when the patient's arm moves, the needle will not be directly affected by the driving force of the pipeline, so that the needle is not easy to fall off the patient's arm, thereby reducing the possibility of safety hazards.

[0029] In a specific embodiment, a Velcro surface is provided on the patient's top; Velcro is provided on the bottom surface of the base; and the base is bonded to the Velcro surface via the Velcro.

[0030] In the present embodiment, the method of bonding with Velcro and Velcro surface is adopted to make the operation simple. During use, the Velcro of the base can be directly pressed onto the Velcro surface to complete the connection between the base and the patient's top. The bonding position of the base and the patient's top can be adjusted by changing the position of the Velcro surface on the patient's top. It should be noted that the design purpose of the present application is to avoid the direct driving of the needle due to the swing of the pipeline. Therefore, the present application replaces the buffer section by designing an annular buckle. During the movement of the patient's arm, the swing of the dialysis tubing will drive the connection position between the buckle and the dialysis tubing, and the dialysis tubing will not directly drive the needle to swing.

[0031] In a specific embodiment, it also includes: a ring; the ring is used to be sleeved on the patient's arm, and the base is fixed on the outer side of the ring.

[0032] In this embodiment, see Figure 2 As shown, the purpose of the above-mentioned ring is to avoid modifying the patient's top. The ring can be directly set to be sleeved on the patient's arm. In order to ensure the comfort of the patient wearing the ring, the material of the ring can be selected as an elastic material, and as shown in FIG. Figure 2 As shown, the cross section of the collar can be set to a wider width, which can further improve the wearing comfort of the patient.

[0033] In a specific embodiment, Figure 2 As shown, a limit slot is provided on the base; the shape of the connector is adapted to the limit slot, and the connector can be inserted into the limit slot, thereby enabling the connector to be clamped in the base.

[0034] It should be noted that the cross-sectional shape of the limiting slot is compatible with the outer shape of the connector, and during the assembly process, the connector can be directly inserted into the limiting slot.

[0035] In a specific embodiment, Figure 1 As shown, the collar includes a semi-circular support portion and an elastic band; one end of the semi-circular support portion is connected to one end of the elastic band, and the other end of the semi-circular support portion is connected to the other end of the elastic band; the base is fixed on the outer surface of the semi-circular support portion. In this way, on the one hand, the semi-circular support portion supports the base to avoid unstable installation of the base, and on the other hand, the elastic band is provided to adapt to the wearing of patients' arms with different diameters.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
