Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a PICC catheter protection sleeve. Background Art

[0002] PICC catheterization, fully known as peripherally inserted central catheter, is a catheterization technique that punctures through a peripheral vein (usually a thick superficial vein in the elbow, such as the basilic vein, median cubital vein, cephalic vein, etc.) and inserts a catheter into a large vein near the heart (such as the superior vena cava or subclavian vein). This technique is mainly used for patients who need long-term intravenous infusion, repeatedly receive irritating drugs (such as chemotherapy drugs), highly permeable or highly viscous drugs, and need rapid infusion or repeatedly receive blood products.

[0003] PICC catheterization is usually simply fixed by a transparent dressing, without a special protection device. However, due to the long PICC catheterization time, during the catheterization process, the patient's body movement, arm swing, dressing or bathing may all rub against the PICC catheter, and it is easy to cause the catheter to become dislodged due to accidental touch or pulling, affecting the treatment effect, and re-catheterization will increase the patient's pain. Summary of the Utility Model

[0004] In view of the technical problem that the existing PICC catheter is not protected, is exposed for a long time, and is easily accidentally touched or pulled to cause the catheter to become dislodged, the utility model provides a PICC catheter protection sleeve.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A PICC catheter protection sleeve includes a soft sleeve main body with an opening and a fixing band detachably connected inside the sleeve main body. The sleeve main body includes a first sleeve body and a second sleeve body both made of elastic materials and arranged at intervals, and a main sleeve body provided between the first sleeve body and the second sleeve body. A zipper for circumferentially limiting the sleeve main body is connected at the opening position; a window communicating with the inside is provided on the main sleeve body, and a sealing band for controlling the opening or closing of the window is provided at the edge of the window; a foldable PVC waterproof sleeve is fixedly connected to the outer periphery of the second sleeve body. When the PVC waterproof sleeve is fully unfolded, it can wrap the main sleeve body, the first sleeve body and the second sleeve body, and a plurality of restraint mechanisms for defining the position of the folded PVC waterproof sleeve are provided around the outer periphery of the second sleeve body;

[0007] A tube fixing sleeve for the passage of a pipeline is provided on the contact surface of the fixing band, and an insertion pocket for accommodating a PICC connector is provided on the other opposite end surface. When the fixing band is fixed to the patient, the insertion pocket is all or partially exposed at the window position.

[0008] Furthermore, two ventilation holes which are arranged at intervals and communicate with the interior are formed in the main sleeve body. A ventilation fan detachably connected to the main sleeve body is provided above each ventilation hole. A plurality of male fasteners are provided on the bottom surface of the ventilation fan, and female fasteners corresponding to the plurality of male fasteners one by one are provided on the main sleeve body.

[0009] Furthermore, the end of the main sleeve body connected to the first sleeve body is defined as the first end, and the end connected to the second sleeve body is defined as the second end. The opening extends from the end of the first sleeve body towards the second end of the main sleeve body.

[0010] Furthermore, one end of the sealing belt is fixedly connected to the main sleeve body, and the other opposite end is adhesively bonded to the main sleeve body through a magic tape.

[0011] Furthermore, air bags are provided on the inner walls of the first sleeve body and the second sleeve body. The air bag connected to the first sleeve body extends from the first end to the second end of the opening; the air bag connected to the second sleeve body is annular, and a layer of silica gel waterproof layer covers the outer surface of the air bag.

[0012] Furthermore, the inner diameter of the first sleeve body is smaller than the inner diameter of the second sleeve body.

[0013] Furthermore, the first end of the PVC waterproof sleeve is fixedly connected to the outer wall of the second sleeve body. A drawstring sleeve is provided on the outer periphery of the second end of the PVC waterproof sleeve. The drawstring sleeve is arranged around the outer periphery of the PVC waterproof sleeve and is close to the end of the PVC waterproof sleeve. A hollow threading cavity for a drawstring to pass through is formed inside the drawstring sleeve, and both ends of the drawstring extend out from the two ports of the threading cavity respectively.

[0014] Furthermore, all the restraint mechanisms include an elastic restraint band with the first end fixedly connected to the end of the second sleeve body, and a connecting support band fixedly connected to the second end of the elastic restraint band. The connecting support band is adhesively bonded to the outer wall of the main sleeve body through a magic tape. When the connecting support band is adhesively bonded to the main sleeve body, the elastic restraint band can press the folded PVC waterproof sleeve inside.
