Description

Technical Field

[0001] This utility model belongs to the technical field of puncture auxiliary equipment, and in particular relates to a puncture device for intravenous drug administration. Background Technology

[0002] In recent years, with the increasing aging of the population, the proportion of elderly patients admitted to hospitals has also been increasing year by year. Elderly patients are characterized by relatively complex conditions, severe conditions, long hospital stays, and poor vascular conditions. Intravenous administration is an important route of drug treatment for elderly patients. Due to their special physiological conditions, nursing staff face greater challenges when administering intravenous therapy. The implantation of central venous catheters via peripheral veins and the implantation of medium and long catheters are nursing techniques to ensure the continuity of treatment and protect the patient's vascular access, so that drugs can be delivered into the patient's body more safely. During the implantation of PICC, medium-length catheters, and arm infusion ports, elderly patients often experience increased difficulty and reduced efficiency in puncture due to the loose skin, fat, and muscle tissue, as well as the narrow and poorly supported location of blood vessels. This not only increases the time required for nursing care but also increases patient suffering, the risk of catheter-related complications, and treatment costs. Utility Model Content

[0003] The purpose of this invention is to provide a puncture device for intravenous drug administration. By using a limiting block, it solves the problems of existing devices, which increase the difficulty of puncture, reduce the efficiency of puncture, increase the time of nursing work, increase the patient's pain, and increase the risk of catheter-related complications and the patient's treatment costs when using them due to the loose skin, fat and muscle tissue of elderly patients, the narrow position of blood vessels and poor support.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a puncture device for intravenous drug administration, comprising a gripper. The gripper is characterized by two sets arranged opposite each other, with each set of grippers having a corresponding clamping claw on its side. Two auxiliary support bars are fixedly installed on the outer walls of both sets of grippers. All four sets of auxiliary support bars are rotatably mounted through and outside a positioning shaft. Positioning discs for limiting support are correspondingly provided on the bottom and top outer walls of the positioning shaft. A torsion spring is sleeved on the outside of the positioning shaft, with its two fixed ends welded to the sides of two sets of positioning blocks. The two positioning blocks are fixedly installed on the sides of the two sets of grippers.

[0005] Furthermore, the two sets of grippers are configured as opposing arc-shaped plate structures, and the sides of the grippers are provided with auxiliary flattening mechanisms.

[0006] Furthermore, the auxiliary leveling mechanism includes an arc-shaped support pad, and two sets of arc-shaped support pads are provided. The two sets of arc-shaped support pads are respectively installed on the sides of the two sets of grippers. A first Velcro is embedded in the inner wall of the side of the gripper, and a second Velcro for aligning and pasting with the first Velcro is embedded in the outer wall of the side of the arc-shaped support pad.

[0007] Furthermore, both the first and second hook and loop fasteners are designed with an arc-shaped structure according to the shape of the gripper, and an assembly and disassembly mechanism is installed between the gripper and the gripper.

[0008] Furthermore, the assembly and disassembly mechanism includes a positioning T-shaped strip and a positioning T-shaped groove. The positioning T-shaped strip is fixedly installed on the side of the gripper, and the outer side wall of the gripper is provided with a positioning T-shaped groove for the positioning T-shaped strip to be inserted and installed.

[0009] Furthermore, the gripper has a first threaded groove symmetrically opened through the outer wall of the side of the positioning T-shaped groove, and the outer wall of the positioning T-shaped strip has two sets of second threaded grooves correspondingly opened through the side, and the first threaded groove and the second threaded groove are threadedly installed with the fastening bolt.

[0010] This utility model has the following beneficial effects: 1. This utility model, by setting up grippers, allows two sets of grippers to be clamped onto the outer side of the patient's loose skin during use, thereby fixing the puncture site on the patient's upper arm. At the same time, by installing an arc-shaped support pad on the inner side of the grippers, the friction between the device and the patient's outer wall is increased, allowing the entire device to be more firmly clamped onto the patient's outer arm. This smooths and tightens the patient's loose skin, making the puncture site fully exposed and flat, facilitating puncture.

[0011] 2. This utility model incorporates an assembly and disassembly mechanism. During use, the gripper and clamp are designed to be detachable, allowing the device to be fitted with the most suitable clamp size according to the patient's arm circumference. This ensures that the clamp size is appropriate while flexibly adapting to the patient's arm circumference, thus providing a guarantee for subsequent puncture procedures while ensuring patient comfort.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figure 1-5As shown, this utility model is a puncture device for intravenous drug administration, including a gripper 1. The gripper 1 is characterized by having two sets of grippers facing each other, and each set of grippers 1 has a corresponding claw 101 installed on its side. Two auxiliary support bars 102 are fixedly installed on the outer wall of each set of grippers 1. The four sets of auxiliary support bars 102 are rotatably installed through and on the outside of the positioning shaft 103. The bottom and top outer walls of the positioning shaft 103 are respectively provided with positioning discs for limiting support. A torsion spring 104 is sleeved and installed on the outside of the positioning shaft 103, and the two fixed ends of the torsion spring 104 are respectively welded to the side of two sets of positioning blocks 105. The two positioning blocks 105 are respectively fixedly installed on the side of the two sets of grippers 1.

[0018] When it is necessary to clamp the claws 101 on the outside of the patient's arm to flatten the loose skin, the medical staff first need to manually lift and flatten the skin on the outside of the patient's arm. Then, they simultaneously pinch the two sets of grippers 1, which bring the two sets of grippers 1 closer together and simultaneously drive the two sets of claws 101 to open. At this time, the torsion spring 104 is in a tightened state as the two sets of grippers 1 move. Then, the two sets of claws 101 in the open state are directly clamped on the outside of the patient's arm. The skin in the area that the medical staff manually flattened is flattened by clamping. After the two sets of claws 101 are clamped, the reaction force generated by the compression of the torsion spring 104 can stably place the claws 101 on the outside of the patient's arm. Example

[0019] Among them, such as Figure 1 As shown, the two sets of grippers 1 are configured as arc-shaped plate structures that open in opposite directions; This technical feature allows the gripper 1 to extend the jaws 101 to their maximum angle with the shortest travel distance, while also allowing medical personnel to apply force more effectively when using the device. Example

[0020] Among them, such as Figure 2-3 As shown, the auxiliary leveling mechanism 2 includes an arc-shaped support pad 202. Two sets of arc-shaped support pads 202 are provided, and the two sets of arc-shaped support pads 202 are respectively installed on the sides of the two sets of grippers 1. A first hook and loop fastener 201 is embedded in the inner wall of the side of the gripper 101, and a second hook and loop fastener 203 for aligning and sticking with the first hook and loop fastener 201 is embedded in the outer wall of the side of the arc-shaped support pad 202. The first hook and loop fastener 201 and the second hook and loop fastener 203 are both set to an arc-shaped structure according to the shape of the gripper 101. The curved support pad 202 is designed to increase the friction between the device and the patient's outer wall, allowing the device to be more securely clamped to the outside of the patient's arm. The first Velcro 201 and the second Velcro 203 provide a portable and replaceable feature for the curved support pad 202. Since the curved support pad 202 is in contact with the patient's skin, it is designed to be replaceable to facilitate the subsequent disinfection and cleaning process of the device. Example

[0021] Among them, such as Figure 4-5 As shown, the assembly and disassembly mechanism 3 includes a positioning T-shaped strip 301 and a positioning T-shaped groove 302. The positioning T-shaped strip 301 is fixedly installed on the side of the gripper 101, and the outer side wall of the gripper 1 is provided with a positioning T-shaped groove 302 for the positioning T-shaped strip 301 to be inserted and installed. The outer side wall of the gripper 1 located at the positioning T-shaped groove 302 is symmetrically provided with a first threaded groove 303. The outer side wall of the positioning T-shaped strip 301 is provided with two sets of second threaded grooves 304. The first threaded groove 303 and the second threaded groove 304 are threadedly installed with the fastening bolt 305. When it is necessary to replace the gripper 101 with one of the appropriate size according to the patient's arm thickness, simply adjust the gripper 101 to the appropriate position and insert the positioning T-shaped strip 301 on its side from top to bottom into the corresponding positioning T-shaped groove 302. When the positioning T-shaped strip 301 moves to the bottom of the positioning T-shaped groove 302, the position of the first threaded groove 303 coincides with the position of the second threaded groove 304. Then, simply pass the fastening bolt 305 through the first threaded groove 303 and screw it to the bottom of the second threaded groove 304 to complete the installation. Disassembly is the same.

[0022] One specific application of this embodiment is: When the clamp 101 needs to be clamped on the outside of the patient's arm to flatten the loose skin, the medical staff first need to manually lift and flatten the skin on the outside of the patient's arm. Then, they simultaneously pinch the two sets of grippers 1, which bring the two sets of grippers 1 closer together and simultaneously drive the two sets of clamps 101 to open. At this time, the torsion spring 104 is in a tightened state as the two sets of grippers 1 move. Then, the two sets of clamps 101 in the open state are clamped on the outside of the patient's arm, which can flatten the skin in the area that the medical staff manually smoothed through clamping. After the two sets of clamps 101 are clamped, the reaction force generated by the compression of the torsion spring 104 can stably place the clamps 101 on the outside of the patient's arm. The arc-shaped support pad 202 here increases the friction between the device and the patient's outer wall, so that the whole device can be clamped more stably on the outside of the patient's arm.
