Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary bracket for PICC dressing change. Background Art

[0002] In the medical field, especially in cancer chemotherapy, peripherally inserted central catheter (PICC) has been widely used to puncture the vein of the arm and directly insert the catheter into the superior vena cava close to the heart. This catheterization technology can avoid direct contact between chemotherapy drugs and arm veins, thereby significantly reducing drug stimulation to blood vessels, effectively protecting upper limb blood vessels, and improving patient treatment comfort and safety.

[0003] However, although PICC catheterization has shown its unique advantages in medical practice, there are still some urgent problems to be solved during its use, especially in the care of the puncture site. Specifically, in order to avoid infection at the puncture site, the puncture site needs to be strictly disinfected and replaced regularly.

[0004] In the existing technology, when changing PICC dressings, medical staff are usually required to lift the catheter with one hand to ensure that the catheter does not interfere with the disinfection and dressing change at the puncture site, and use the other hand to disinfect the puncture point. This process requires medical staff to have high operating skills and stability. Any carelessness may cause catheter displacement or infection at the puncture site. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an auxiliary stent for PICC dressing change, which is used to solve the technical problems mentioned in the above background technology.

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] See also Figure 1 The auxiliary bracket for PICC dressing change in the first embodiment of the utility model comprises a fixing frame 10 and an auxiliary clamp 20, wherein the fixing frame 10 comprises a main body 11 and elastic clamp arms 12 symmetrically arranged on both sides of the main body 11;

[0029] The auxiliary clamp 20 is fixed on the main body 11 . The auxiliary clamp 20 has two elastic clamps 21 arranged opposite to each other. The adjacent surfaces of the two elastic clamps 21 are respectively provided with clamping teeth 22 .

[0030] In actual application, the fixing frame 10 is fixed to the patient's arm, and the auxiliary clamp 20 clamps the catheter and slightly raises it to a certain angle, so that medical staff do not need to hold the catheter during the dressing change process, which significantly reduces the difficulty of operation. This design can greatly reduce the workload of medical staff, especially for the dressing change process that requires a long time or delicate operation. In addition, the two relatively arranged elastic clamps 21 of the auxiliary clamp 20 and the clamping teeth 22 arranged thereon can effectively clamp the catheter, ensuring that the catheter is not easy to loosen or shift during the dressing change process, thereby ensuring the safety and effectiveness of the dressing change process.

[0031] For details, see Figure 2 The elastic clamp 21 is fixed on the inner side of the main body 11, and a driving piece 30 opposite to the elastic clamp 21 is provided on the outer side of the main body 11. The two driving pieces 30 are extended outwards to form an inverted figure eight shape. In practical applications, when clamping a catheter, medical staff can pinch the two driving pieces 30 to drive the two elastic clamps 21 to open the bayonet, and then clamp the catheter between the two elastic clamps 21. After adjusting the lifting angle of the catheter, release the driving piece 30, and the two elastic clamps 21 will automatically close, thereby firmly fixing the catheter. At this time, medical staff can focus more on the dressing change operation itself without worrying about the catheter sliding or falling off, which not only improves the efficiency of dressing change, but also ensures the safety of operation.

[0032] It is worth mentioning that since the elastic clamp 21 is located on the inner side of the main body 11, after the fixing frame 10 is fixed to the patient's arm, a certain gap is left between the elastic clamp arm 12 and the patient's arm. This gap can allow the catheter to pass through and then be clamped by the auxiliary clamp 20.

[0033] For further information, see Figure 2 The elastic clamp arm 12 includes a support section 121 connected to the main body 11, and a clamping section 122 connected to the support section 121. In practical applications, the fixing frame 10 mainly relies on the clamping section 122 to clamp the two sides of the patient's arm to achieve fixation, while the support section 121 does not fit the patient's arm, and its main function is to prop up the auxiliary clamp 20 to a certain height to ensure that the catheter fixed on the auxiliary clamp 20 is lifted.

[0034] In this embodiment, the support section 121 and the elastic clamp 21 form an acute angle, which can be 60° or 70°. It can be understood that the clamping force of the two clamping sections 122 can be effectively adjusted by designing different angles. A smaller angle will increase the clamping force of the clamping section 122, while a larger angle will reduce the clamping force of the clamping section 122. This angle adjustment can be flexibly adjusted according to the thickness of the patient's arm.

[0035] Furthermore, the clamping section 122 is provided with a flexible protective cover (not shown), which can be made of silicone or rubber. The flexible protective cover is used to reduce the pressure exerted by the clamping section 122 on the arm, increase the comfort when wearing, and enable the patient to maintain a relatively comfortable state during long-term fixation.

[0036] In addition, the auxiliary stent for PICC dressing change in this embodiment is made of metal material and can be repeatedly used after disinfection. Of course, it can also be made of plastic integral injection molding as a disposable product, which can be adjusted as needed. This embodiment is only an example and not a limitation.

[0037] In summary, in the above-mentioned embodiment of the utility model, the auxiliary bracket for PICC dressing change, the fixing frame 10 is fixed to the patient's arm, and the auxiliary clamp 20 clamps the catheter and slightly raises it at a certain angle, so that the medical staff does not need to hold the catheter during the dressing change process, which significantly reduces the difficulty of operation. This design can greatly reduce the workload of medical staff, especially for the dressing change process that requires a long time or delicate operation. In addition, the two relatively arranged elastic clamps 21 of the auxiliary clamp 20 and the clamping teeth 22 arranged thereon can effectively clamp the catheter, ensuring that the catheter is not easy to loosen or shift during the dressing change process, thereby ensuring the safety and effectiveness of the dressing change process.

[0038] Please refer to Figure 3 The auxiliary bracket for PICC dressing change in the second embodiment of the utility model is different from the auxiliary bracket for PICC dressing change in the first embodiment in that: the two elastic clamps 21 are fixedly arranged on the outer side of the main body 11, and a pull ring 40 is provided on the side of the elastic clamp 21 facing away from the clamping teeth 22. It can be understood that the elastic clamp 21 in this embodiment is arranged on the outer side of the main body 11. Compared with the scheme in which the elastic clamp 21 is arranged on the inner side of the main body 11 in the first embodiment, direct contact between the elastic clamp 21 and the patient's arm can be avoided, so that the elastic clamp arm 12 can be completely fitted with the patient's arm, thereby improving the fixing effect of the fixing frame 10 on the patient's arm. Secondly, the catheter does not need to be inserted between the elastic clamp arm 12 and the patient's arm, and can be directly clamped and fixed by the two elastic clamps 21 on the outer side of the fixing frame 10, which is more convenient to operate.

[0039] In this embodiment, when clamping the catheter, the medical staff can pull the two pull rings 40 to drive the two elastic clamps 21 to open the clamping mouth, and then clamp the catheter between the two elastic clamps 21. After adjusting the lifting angle of the catheter, release the pull ring 40, and the two elastic clamps 21 will automatically close, thereby firmly fixing the catheter. At this time, the medical staff can focus more on the dressing change operation itself without worrying about the catheter sliding or falling off, which not only improves the efficiency of the dressing change, but also ensures the safety of the operation.

[0040] Furthermore, the pull ring 40 is connected to a position near the end of the elastic clamp 21. This design allows medical staff to open and close the elastic clamp 21 with less force.

[0041] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
