Description

Technical Field

[0001] This utility model relates to the field of infusion set technology, specifically to an infusion set with adjustable infusion rate. Background Technology

[0002] Infusion sets are commonly used medical devices used to deliver various medications, blood, nutrients, etc., into the body according to the patient's condition. Adjusting the infusion rate is a fundamental nursing skill—the first task after successful intravenous puncture. Currently, because the infusion apparatus is directly external, it's easy for others to adjust the infusion rate themselves, potentially leading to safety issues. Furthermore, it's impossible to prevent others from adjusting the rate after medical staff have completed the initial adjustment.

[0003] For example, patent application number CN201921131257.5, this utility model belongs to the field of medical supplies technology, specifically relating to an infusion set that can precisely adjust the infusion rate and prevent backflow. This allows for a greater deformation range of the infusion tubing, improving the sensitivity of infusion rate adjustment. The pressure plate has a plate-like structure with a large contact area with the infusion tubing, resulting in good compression. However, during use, because the infusion adjustment mechanisms are directly external, it is easy for other personnel to adjust the infusion rate themselves, potentially causing safety issues. Furthermore, it is impossible to prevent other personnel from adjusting the rate after medical staff have completed the adjustment.

[0004] For example, patent application number CN202022194026.8 describes a light-proof, adjustable-speed infusion set specifically designed for HIV / AIDS. This design allows for precise control of the infusion flow rate while protecting the infusion from light and facilitating monitoring of the infusion status. It also avoids direct air venting of the infusion solution, preventing overflow and PICC line blockage. During infusion, because the infusion adjustment mechanisms are external, other personnel can easily adjust the infusion rate, potentially causing safety issues. Furthermore, it fails to prevent other personnel from adjusting the rate after medical staff have completed the initial adjustment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an infusion set with adjustable infusion rate. This solves the problem that during infusion, since the infusion adjustment mechanism is directly external, it is easy for other people to adjust the infusion rate themselves, which may cause safety issues. Furthermore, it is impossible to prevent other people from adjusting the rate after medical staff have finished adjusting it.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an infusion set with adjustable infusion rate, comprising an infusion tube, an adjustment mechanism provided on the outer side of one end of the infusion tube, and a drip chamber provided on the other end of the infusion tube, wherein a puncture element is provided on one end of the drip chamber, and the drip chamber is connected to the infusion tube at the connection point.

[0007] The adjusting mechanism includes a fixed plate, a sealing plate at the top of the fixed plate, and a lifting plate at the bottom of the sealing plate. The lifting plate contacts the inner wall of the fixed plate. The surface of the lifting plate has holes, and the bottom of the holes has grooves. The diameter of the holes is larger than the diameter of the grooves. A plastic bolt is installed inside the holes, with its bottom end extending into the grooves. A pressing plate is located at the bottom of the lifting plate. The downward movement of the plastic bolt allows it to contact a sleeve. Rotating the plastic bolt with a tool pushes the pressing plate downward, controlling the infusion rate. The lifting plate also allows the top of the plastic bolt to enter the holes, surrounding the bolt and reducing the need for other personnel to rotate it, thus preventing unauthorized control of the infusion rate.

[0008] Preferably, the sealing plate has multiple ball bearings on both sides of one end, and a positive Velcro strap is provided on the end of the sealing plate near the ball bearings. The ball bearings make it more convenient for the sealing plate to operate automatically.

[0009] Preferably, a negative hook and loop fastener is provided on one side of the positive hook and loop fastener. The positive hook and loop fastener and the negative hook and loop fastener are adhered to each other. When the positive hook and loop fastener moves, the distance between the positive hook and loop fastener and the negative hook and loop fastener decreases, and finally the positive hook and loop fastener and the negative hook and loop fastener come into contact.

[0010] Preferably, the top of the pressing plate is provided with a sleeve, which is threadedly connected to a plastic bolt, allowing the rotating plastic bolt to move and push the pressing plate downward.

[0011] Preferably, a connecting rod is fixedly provided at one end of the sleeve, and the sleeve is fixedly connected to the inner wall of the fixed plate through the connecting rod, which can improve the stability of the sleeve. The sleeve is in contact with the pressing plate to prevent the sleeve from moving downward with the pressing plate.

[0012] Preferably, a horizontal groove is provided on one end surface of the fixing plate, and the sealing plate passes through the horizontal groove and is in contact with the fixing plate.

[0013] Beneficial effects

[0014] This invention provides an infusion set with adjustable infusion rate. Compared with the prior art, it has the following advantages:

[0015] 1. This adjustable infusion set allows the plastic bolt to contact the sleeve by moving downwards. Rotating the plastic bolt with a tool pushes the pressure plate below downwards, controlling the infusion rate. The top of the plastic bolt enters the hole, and the lifting plate surrounds the plastic bolt, reducing the need for other personnel to rotate it and preventing them from controlling the infusion rate.

[0016] 2. In this adjustable infusion set, the sealing plate moves to the lifting plate via the transverse groove, causing the positive electrode hook and loop fastener to move. This reduces the distance between the positive and negative electrodes, eventually bringing them into contact. Because the positive and negative electrodes are bonded together, the sealing plate can be stably positioned on top of the plastic bolt, thus shielding the bolt and reducing manual operation, making it convenient for long-term use.

Detailed Implementation

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-24. This utility model provides a technical solution: an infusion set with adjustable infusion rate, including an infusion tube 1, an adjustment mechanism 2 is provided on the outer side of one end of the infusion tube 1, and a drip chamber 3 is provided on the other end of the infusion tube 1. A puncture element 4 is provided on one end of the drip chamber 3, and the drip chamber 3 is connected to the infusion tube 1 at the connection point.

[0024] The adjusting mechanism 2 includes a fixed plate 201, a sealing plate 202 is provided inside the top of the fixed plate 201, a lifting plate 203 is provided at the bottom of the sealing plate 202, the lifting plate 203 is in contact with the inner wall of the fixed plate 201, the surface of the lifting plate 203 is provided with a hole 204, the bottom of the hole 204 is provided with a groove 205, the diameter of the hole 204 is larger than the diameter of the groove 205, a plastic bolt 206 is provided inside the hole 204, the bottom end of the plastic bolt 206 extends into the interior of the groove 205, and a pressing plate 207 is provided at the bottom of the lifting plate 203.

[0025] A sleeve 211 is provided on the top of the pressing plate 207. The sleeve 211 is threadedly connected to the plastic bolt 206. A connecting rod 212 is fixedly provided at one end of the sleeve 211. The sleeve 211 is fixedly connected to the inner wall of the fixing plate 201 through the connecting rod 212. A transverse groove 213 is provided on one end surface of the fixing plate 201. The sealing plate 202 passes through the transverse groove 213 and is in contact with the fixing plate 201.

[0026] Please see Figure 1-3 The sealing plate 202 has multiple balls 208 on both sides of one end. A positive hook and loop fastener 209 is provided on the end of the sealing plate 202 near the balls 208, and a negative hook and loop fastener 210 is provided on one side of the positive hook and loop fastener 209. The positive hook and loop fastener 209 and the negative hook and loop fastener 210 are bonded together. When the sealing plate 202 is moved, it moves to the lifting plate 203 through the transverse groove 213, which also moves the positive hook and loop fastener 209, reducing the distance between the positive hook and loop fastener 209 and the negative hook and loop fastener 210, and finally bringing the positive hook and loop fastener 209 and the negative hook and loop fastener 210 into contact. Because the positive hook and loop fastener 209 and the negative hook and loop fastener 210 are bonded together, the sealing plate 202 can be stably positioned on the plastic bolt 206, covering the plastic bolt 206, reducing manual operation of the plastic bolt 206, and facilitating long-term operation.

[0027] During operation, the puncture device 4 comes into contact with the skin, allowing the medication to flow through the infusion tube 1 and into the drip chamber 3. The medication is then released through the puncture device 4, completing the infusion process. During infusion, because the fixing plate 201 is open, the plastic bolt 206 is moved downwards, allowing its bottom end to pass through the hole 204 and groove 205 and contact the sleeve 211. Then, the plastic bolt 206 is rotated. Since the plastic bolt 206 is threaded into the sleeve 211, its bottom end enters the sleeve 211 and contacts the lower pressure plate 207. The downward movement of the plastic bolt 206 pushes the pressure plate 207 downwards. Because the infusion tube 1 passes through the fixing plate 201 and contacts the pressure plate 207, it presses down on the infusion tube 1 below the pressure plate 207, controlling the infusion rate. During operation, the tip of the plastic bolt 206 is inserted into the hole 204, allowing it to contact the lifting plate 203. Since the plastic bolt 206 is rotated using a tool, the lifting plate 203 surrounds it, reducing the need for other personnel to manipulate its rotation and control the infusion rate. Subsequently, the sealing plate 202 moves via the transverse groove 213 onto the lifting plate 203, causing the positive electrode hook and loop fastener 209 to move, reducing the distance between it and the negative electrode hook and loop fastener 210 until they come into contact. This adhesion ensures the sealing plate 202 remains stably positioned above the plastic bolt 206, shielding it and reducing manual manipulation, thus facilitating prolonged operation.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
