Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary instruments, in particular to a wrench for a sheath fixing clamp. Background Art

[0002] The main purpose of the sheath is to establish a channel, and it needs to be firmly fixed during puncture surgery or catheter operation. It is usually fixed by applying tape, but the glue will adhere to the sheath, increasing the difficulty of subsequent cleaning. Therefore, the sheath is supported by a sheath clamp, and then the clamp is attached to the patient using medical tape. The addition of the sheath clamp makes the entire device larger, especially the wrench area, which can easily cause the sheath to loosen due to accidental contact. Therefore, we propose a wrench for the sheath clamp to reduce the probability of the sheath loosening due to accidental contact with the wrench. Utility Model Content

[0003] The main purpose of the utility model is to provide a wrench for a sheath fixing clamp, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A wrench for a sheath fixing clamp comprises two connecting seats respectively fixedly connected to two clamp arms, the two clamp arms being hingedly connected to form a sheath fixing clamp, and the sheath fixing clamp being affixed to the patient via medical tape, a wrench arm being rotatably connected within the connecting seat, and the two clamp arms being driven to open by the two wrench arms moving towards each other, the shape of the wrench arm matching the shape of the clamp arm, and a pressure plate being installed at the end of the wrench arm away from the connecting seat.

[0006] Preferably, a cavity matching the shape of the sheath is formed between the two clamp arms, an expansion plate is installed at the lower end of the clamp arm, the expansion plate is used to increase the contact area between the sheath fixing clamp and the medical tape, and a plug-in slot is provided at one end of the clamp arm close to the connecting seat.

[0007] Preferably, a plug-in block is installed at one end of the connecting seat close to the clamping arm, and the plug-in block is engaged with the plug-in slot.

[0008] Preferably, the pressure plate includes a top pressing part, which is fixedly connected to the wrench arm, and side pressing parts are installed at both ends of the top pressing part. When the wrench arm rotates toward the direction close to the clamp arm, the top pressing part and the side pressing part are in contact with the medical tape.

[0009] Preferably, the upper end of the expansion plate is engraved with lines, the extending direction of the lines forms an angle with the medical tape, and the lower end of the expansion plate is installed with a soft pad.

[0010] Preferably, a spring is sleeved on the hinge shafts of the two clamping arms, and two ends of the spring are respectively in contact with the two clamping arms.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The sheath clamp can be opened and closed by setting a rotatable lever arm. When the sheath is fixed, the lever arm is rotated toward the clamp arm so that it fits on the outside of the clamp arm. This not only reduces the volume of the entire sheath clamp but also hides the lever arm, greatly reducing the chance of it being accidentally touched.

[0013] 2. When the wrench arm rotates to completely fit the clamp arm, the pressure plate just presses the medical tape, thereby improving the connection firmness between the medical tape and the sheath clamp. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-Figure 4 As shown, a wrench for a sheath fixing clamp includes two connecting bases 2 respectively fixedly connected to two clamp arms 1. The two clamp arms 1 are hinged to form a sheath fixing clamp. The sheath fixing clamp is affixed to the patient through medical tape 6. A wrench arm 3 is rotatably connected inside the connecting base 2. The two wrench arms 3 move closer to each other to drive the two clamp arms 1 to open. The shape of the wrench arm 3 matches the shape of the clamp arm 1. A pressure plate 4 is installed at the end of the wrench arm 3 away from the connecting base 2.

[0023] In the initial state, the wrench arm 3 is at the position farthest from the clamp arm 1, which is convenient for holding. The two wrench arms 3 are driven by external force to move towards each other, and the two wrench arms 3 drive the two clamp arms 1 to move away from each other, and then the sheath is placed between the two clamp arms 1. The external force is then removed, and the two clamp arms 1 form a support and fixation for the sheath. The clamp arms 1 are pasted on the patient's body using medical tape 6. Finally, the wrench arm 3 is rotated to make the pressure plate 4 move above the medical tape 6, squeezing the medical tape 6 to improve the connection firmness between the medical tape 6 and the sheath fixing clamp.

[0024] A cavity matching the outer shape of the sheath tube 5 is formed between the two clamping arms 1 , and a spring 12 is sleeved on the hinge shafts of the two clamping arms 1 , with both ends of the spring 12 respectively abutting against the two clamping arms 1 .

[0025] In order to increase the contact area between the medical tape 6 and the clamp arm 1 , an expansion plate 13 is installed at the lower end of the clamp arm 1 in this embodiment. The expansion plate 13 is used to increase the contact area between the sheath fixing clamp and the medical tape 6 .

[0026] Building on the above solution, to further increase the friction coefficient between medical tape 6 and expansion plate 13, this embodiment features grooves 14 engraved on the upper end of expansion plate 13. These grooves extend at an angle to medical tape 6, thereby increasing the friction coefficient. Furthermore, to alleviate the pressure of expansion plate 13 on the patient's skin, a cushion 15 is installed on the lower end of expansion plate 13, providing a cushioning effect.

[0027] In order to increase the contact area between the pressing plate 4 and the medical tape 6, the pressing plate 4 includes a top pressing portion 41, which is fixedly connected to the wrench arm 3. Side pressure portions 42 are installed at both ends of the top pressing portion 41. When the wrench arm 3 rotates toward the direction close to the clamp arm 1, the top pressing portion 41 and the side pressure portion 42 are in contact with the medical tape 6.

[0028] If rotating the wrench arm 3 to overlap with the clamping arm 1 still affects subsequent operations, the wrench arm 3 can be removed. Specifically, a plug-in slot 11 is provided at one end of the clamping arm 1 close to the connecting seat 2; a plug-in block 21 is installed at one end of the connecting seat 2 close to the clamping arm 1, and the plug-in block 21 is snap-fitted to the plug-in slot 11. The connecting seat 2 can be quickly disassembled and assembled by snapping, thereby improving practicality.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
