Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary articles for catheter placement, and particularly relates to a hemostatic cuff for PICC. Background Art

[0002] PICC catheterization, also known as peripherally inserted central catheterization, is to puncture a vein in the peripheral arm using a catheter, and the catheter reaches a large vein close to the heart, avoiding direct contact between chemotherapy drugs and arm veins. Coupled with the very fast blood flow rate in the large vein, chemotherapy drugs can be quickly diluted, preventing drug irritation to blood vessels. Therefore, it can effectively protect the upper limb veins, reduce the occurrence of phlebitis, relieve the pain of patients, and improve the quality of life of patients.

[0003] After catheterization, to avoid touching and pulling the exposed catheter during dressing or arm movement, most patients will wear an elastic cuff to wrap the area of the catheter and the puncture site. However, the structure of this cuff is relatively simple, and it can only play a role in covering the catheter and the puncture site during use. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a hemostatic cuff for PICC. An openable covering towel is arranged inside the cuff. When bleeding occurs at the puncture site, a squeezing bladder or other convex object can be placed at this position. After covering the covering towel and the binding band, the squeezing bladder just placed inside can play a role in pressing the bleeding point. Compared with the traditional cuff, it has stronger practicability, and no other hand is needed as an auxiliary during pressing, solving the problem that when bleeding occurs at the traditional puncture site, another hand is needed for pressing, resulting in restricted movement.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A hemostatic cuff for PICC includes a cuff sleeved on the arm. The outer side of the cuff is provided with a hook-and-loop fastener A surface. A covering towel is arranged at the middle position of the cuff. A binding band adhered to the hook-and-loop fastener A surface is wound outside the covering towel. One end of the covering towel is provided with an adhesive tape adhered to the hook-and-loop fastener A surface. A gasket is pasted on the inner side of the cuff.

[0007] Further, a circular sticker B surface is arranged on the outer side of the gasket, and a squeezing bladder is arranged on the inner side of the gasket. A catheter is arranged at the upper end of the squeezing bladder. By injecting gas or liquid into the squeezing bladder through the catheter, the gasket can squeeze the bleeding point.

[0008] Further, a plurality of vertical sticker A surfaces adhered to the circular sticker B surface are arranged on the inner side of the covering towel. The gasket can be adhesively fixed to the inner side of the covering towel according to the position of the bleeding point by the adhesion between the circular sticker B surface and the vertical sticker A surface.

[0009] Furthermore, one end of the drawstring and the inner side surface of the adhesive tape are both provided with a Velcro B surface adhered to the Velcro A surface, so that the drawstring and the covering towel can be firmly fixed to the sleeve, so that the gasket can effectively press the bleeding point.

[0010] Furthermore, a connector with a non-return function is provided at the upper end of the catheter to prevent the liquid or gas injected into the extrusion bag from flowing out.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The gasket in the utility model can inject gas or cooler liquid into the squeezing bag through a catheter, thereby propping up the squeezing bag, thereby pressing the bleeding point to stop bleeding. When using the squeezing bag, it will not affect the patient's activities, and when a cooler liquid is injected, it can further play an analgesic and coagulation role on the bleeding point. It is more comfortable to use and reduces the pain and discomfort caused by the bleeding point.

[0013] 2. In the utility model, the drawstring and adhesive tape are connected to the sleeve by Velcro, and the covering towel can be opened by pulling the drawstring and adhesive tape. When there is no need to press the bleeding point, the gasket with the extrusion bag pasted on the inner side of the covering towel can be removed, so that the device can be used as an ordinary sleeve; when it is needed, the gasket only needs to be pasted on the appropriate position of the bleeding point on the inner side of the covering towel by adhering the vertical strip sticker on the A side and the round sticker on the B side, and then the covering towel is fixed in position by the drawstring and adhesive tape. The operation is simple and convenient, and no other hand is needed for assistance when pressing, which solves the problem that bleeding at the traditional puncture point requires another hand to press and the movement is restricted.

[0020] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As shown in the Figures 1-4 appendix.

[0022] A hemostatic cuff for PICC includes a sleeve 1 that is sleeved on the arm. A covering towel 2 is connected to the middle position of the sleeve 1. A strap 3 with a magic tape B surface laid on the inner side is wound around the middle position on the outer side of the covering towel 2. The strap 3 is tightly adhered to the sleeve 1 through the magic tape B surface. One end of the covering towel 2 is connected with a sticky tape 4 that is adhered to the magic tape A surface 11 provided at the middle position on the outer side of the sleeve 1. The sticky tape 4 is tightly adhered to the sleeve 1 through the magic tape B surface provided on the inner side, playing a role in fastening the strap 3. The covering towel 2 is adhered to the B surface circular sticker 61 provided on the outer side of the gasket 6 through 8 - 10 A surface vertical strips 5 laid on the inner side.

[0023] An extrusion bladder 62 for pressing the bleeding point is provided inside the gasket 6. One end of the extrusion bladder 62 is communicated with a catheter 63 with a check valve function at one end. Liquid or gas can be injected into the extrusion bladder 62 through the catheter 63. The liquid with a lower temperature can play a role in relieving pain and reducing swelling at the bleeding point. Propping up the extrusion bladder 62 can squeeze and fix the bleeding point to stop bleeding. The connection head with a check valve function provided on the catheter 63 can prevent the liquid or gas in the extrusion bladder 62 from flowing out, avoiding affecting the extrusion of the bleeding point by the gasket 6.

[0024] Embodiment 1:

[0025] First, put the sleeve 1 on the patient's arm. When in use, first pull the strap 3 outwards to separate the B-side of the Velcro on the inner side of the strap 3 from the A-side of the Velcro 11, and then pull the adhesive tape 4 outwards to separate the B-side of the Velcro on the inner side of the adhesive tape 4 from the A-side of the Velcro 11. Open the covering towel 2, and then according to the position of the bleeding point, place the gasket 6 in the appropriate position, so that the gasket 6 is adhered to the A-side vertical strip sticker 5 through the B-side round sticker 61 on the outer side, so that the gasket 6 is fixed inside the covering towel 2. Then pull the covering towel 2 and the adhesive tape 4 inwards to fix and adhere the adhesive tape 4 to the A-side of the Velcro 11, so as to fix the positions of the covering towel 2 and the sleeve 1, and thus fix the gasket 6, squeeze the bleeding point, and then pull the strap 3 inwards to fix and adhere the strap 3 to the A-side of the Velcro 11, reinforce the position of the covering towel 2, and increase the squeezing and fixing of the gasket 6 on the bleeding point. Then inject a liquid with a lower temperature into the extrusion bladder 62 through the catheter 63. Then the extrusion bladder 62 is propped up, and the gasket 6 fixes and presses the bleeding point of the syringe, which is convenient for the patient to dress and move. At the same time, the connector with a backflow prevention function provided at one end of the catheter 63 can prevent the liquid in the extrusion bladder 62 from flowing out.

[0026] When it is not necessary to press the bleeding point, first pull the strap 3 outwards to separate the B-side of the Velcro on the inner side of the strap 3 from the A-side of the Velcro 11, and then pull the adhesive tape 4 outwards to separate the B-side of the Velcro on the inner side of the adhesive tape 4 from the A-side of the Velcro 11.
