Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a connecting tube fixing clamp for artery puncture. Background Art

[0002] When replacing the access route, the connecting tube of the arterial puncture needle requires medical staff to clamp the tube with forceps to seal the tube to prevent blood from spilling. However, this method requires medical staff to continuously exert force to maintain the clamping state, which is time-consuming and labor-intensive and inconvenient to use. Utility Model Content

[0003] The utility model aims to provide a connecting tube fixing clamp for arterial puncture, so as to solve the problem in the prior art that when replacing the connecting tube passage of the arterial puncture needle, medical staff need to use pliers to continuously apply force to seal the connecting tube, which is time-consuming and labor-intensive.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The basic technical solution provided by the utility model is: a connecting tube fixing clamp for arterial puncture, comprising a mounting belt and a mounting seat, the mounting seat is fixedly connected to the mounting belt, the two ends of the mounting belt are respectively fixedly connected with Velcro surface A and Velcro surface B, the mounting belt is fixed to the Velcro surface B through the Velcro surface A, the mounting seat is provided with a mounting groove, the mounting seat is rotatably connected with a pressure plate, the pressure plate is clamped with the mounting groove, the mounting seat is fixedly connected with a slide seat, the mounting seat is slidably connected with a clamping block through the slide seat, a tension spring is arranged between the clamping block and the slide seat, and the clamping block is used to fix the pressure plate.

[0006] The principle of the basic technical solution: the fixing belt is fixed to the patient's arm through the cooperation of Velcro A side and Velcro B side, and the connecting tube of the puncture needle is installed on the mounting groove. When the connecting tube needs to change the passage, the connecting tube is squeezed to seal the tube by rotating the pressure plate, and the pressure plate is fixed by the clamping block. After the connecting tube has completed the passage change, the clamping block is pulled to separate it from the pressure plate, and the pressure plate can be rotated to separate it from the connecting tube to make it unobstructed.

[0007] The beneficial effects of the basic technical solution are: through the design of Velcro, the device can adapt to patients with different arm thicknesses, and has a wide range of adaptability. The connection tube can be easily squeezed to seal it through the cooperation of the pressure plate and the mounting groove. The pressure plate is fixed through the cooperation of the tension spring and the card block, so that the connection tube continues to maintain a sealed state, which solves the problem in the prior art that when replacing the connection tube passage of the arterial puncture needle, medical staff need to use pliers to continuously apply force to seal the connection tube, which is time-consuming and labor-intensive. At the same time, the design of the mounting groove is conducive to improving the stability of the connecting tube, thereby reducing the risk of the puncture needle falling off due to the movement of the connecting tube.

[0008] Preferably, the lower surface of the clamping block is parallel to the upper surface of the pressing plate, and the upper surface of the clamping block is tangent to the lower surface of the pressing plate.

[0009] With the above arrangement, when the pressing plate rotates downward, the pressing plate generates a tangential force on the clamping block, causing the clamping block to move towards the sliding seat to disengage from the pressing plate, and at the same time stretching the tension spring; when the pressing plate moves below the clamping block, the tension spring pulls the clamping block to move above the pressing plate, thereby fixing the pressing plate. The structure is simple and beneficial for use.

[0010] Preferably, a pull plate is fixedly connected to the clamping block.

[0011] With the above arrangement, pulling the clamping block through the pull plate is beneficial for the patient to use.

[0012] Preferably, a buffer layer is fixedly connected to the mounting belt.

[0013] With the above arrangement, through the setting of the buffer layer, the comfort of the patient is improved.

[0014] Preferably, the mounting belt is made of textile cotton, and the buffer layer is made of hydrogel.

[0015] With the above arrangement, the textile cotton material ensures the quality of the mounting belt, and the hydrogel has strong water absorption, avoiding the accumulation of the patient's sweat on the patient's skin, thus ensuring the cleanliness of the patient's face.

[0016] Preferably, multiple groups of ventilation holes are provided in both the mounting belt and the buffer layer.

[0017] With the above arrangement, through the design of the ventilation holes, the skin of the patient is kept well ventilated. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below in conjunction with the drawings and embodiments:

[0023] like Figures 1 to 3 As shown, a connecting tube fixing clamp for arterial puncture comprises a mounting belt 1 and a mounting seat 6, the mounting seat 6 is fixedly connected to the mounting belt 1, and the two ends of the mounting belt 1 are respectively fixedly connected with Velcro A surface 3 and Velcro B surface 4, the mounting belt 1 is fixed with Velcro A surface 3 and Velcro B surface 4 through Velcro B surface 3, the mounting belt 1 is fixedly connected with a buffer layer 2, and the mounting belt 1 and the buffer layer 2 are both provided with multiple groups of air holes 5, the mounting belt 1 is made of textile cotton material, and the buffer layer 2 is made of hydrogel material, the mounting seat 6 is provided with a mounting groove 7, the mounting seat 6 is rotatably connected with a pressing plate 8, the pressing plate 8 is clamped with the mounting groove 7, the mounting seat 6 is fixedly connected with a slide seat 12, the mounting seat 6 is slidably connected with a clamping block 9 through the slide seat 12, a tension spring 10 is arranged between the clamping block 9 and the slide seat 12, the clamping block 9 is used to fix the pressing plate 8, the clamping block 9 is fixedly connected with a pulling plate 11, the lower surface of the clamping block 9 and the upper surface of the pressing plate 8 are parallel to each other, and the upper surface of the clamping block 9 is tangent to the lower surface of the pressing plate 8.

[0024] The specific implementation process is as follows:

[0025] When using the present invention, firstly, the fixing belt is fixed on the patient's arm through the cooperation of the Velcro A surface 3 and the Velcro B surface 4, and the connecting tube of the puncture needle is installed on the mounting groove 7. When the passage of the connecting tube needs to be replaced, the pressing plate 8 is rotated to squeeze the connecting tube to achieve the effect of sealing the tube. In the process of rotating the pressing plate 8, the lower surface of the pressing plate 8 is tangent to the upper surface of the clamping block 9, and the pressing plate 8 generates a tangential force on the clamping block 9 to make the clamp detach from the pressing plate 8, and at the same time, the tension spring 10 is stretched to generate a tension. When the pressing plate 8 is below the clamping block 9, the tension of the tension spring 10 pulls the clamping block 9 to make it clamped on the top of the pressing plate 8, thereby fixing the pressing plate 8 and keeping the connecting tube in a sealed state. After completing the work of replacing the connecting tube, the clamping block 9 is pulled out of the pressing plate 8 by the pulling plate 11, and then the pressing plate 8 is rotated to make it detach from the connecting tube to make it unobstructed. The present device has high stability and is relatively simple to operate, which is conducive to use.
