Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical delivery technology, and in particular relates to a micro-pump extension tube with adjustable length. Background Technology

[0002] A micro pump is a small pump used for precise control of liquid flow. It is typically used in applications requiring high precision and low flow rates, such as laboratory analysis, pharmaceutical delivery, chemical reaction control, and various industrial processes. The design of micro pumps enables stable liquid delivery over a very small flow range, typically from microliters to milliliters. A micro pump extension tube is an accessory used to connect the micro pump to other equipment or containers for better control of liquid delivery and distribution. In the field of medical delivery, the extension tube of a micro-infusion pump has a fixed size, which cannot meet the needs of patients' movement and changing positions. Currently, patients who need to receive pumped medication in clinical practice encounter two situations when connecting the micro-infusion pump extension tube: if the extension tube is too long, it will affect their movement; if it is too short, it will be easy to pull when turning over in bed. Therefore, we have proposed a micro-infusion pump extension tube that is easy to adjust in length. Utility Model Content

[0003] The purpose of this invention is to provide a micro-infusion pump extension tube with adjustable length. This solves the problem that existing equipment has a fixed size and cannot meet the needs of patients' activities and changes in body position. Currently, patients who need pumped medication in clinical practice encounter two situations when connecting the micro-infusion pump extension tube: the extension tube is too long and affects their activities, while it is too short and can easily be pulled when turning over in bed.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a micro-infusion pump extension tube with adjustable length, comprising a micro-infusion pump extension tube body. The extension tube body has its winding portion located inside the cavity of the protective upper and lower covers, with both ends outside the cavity. An auxiliary mounting plate is fixedly installed on the inner wall of the bottom of the lower cover, and a rotating part is rotatably mounted above the auxiliary mounting plate. A positioning post for mounting the center end of a spiral spring is provided at the center of the auxiliary mounting plate. The outer end of the spiral spring is connected to the inner wall of the rotating part. The micro-infusion pump extension tube body is wound around the outside of the rotating part. An auxiliary disassembly / reassembly mechanism is connected between the upper and lower covers.

[0005] Furthermore, the auxiliary disassembly mechanism includes an abutting clip and an abutting slot. The bottom outer wall of the protective upper cover is provided with an abutting clip, and the top outer wall of the protective lower cover is correspondingly provided with an abutting slot for the abutting clip to be inserted and installed.

[0006] Furthermore, the protective lower cover has two sets of positioning threaded grooves symmetrically opened on the outer walls of both sides of the contact slot, and the contact slot has two sets of mating threaded grooves symmetrically opened on the outer walls of both sides. The positioning threaded grooves and mating threaded grooves are threadedly installed with the fastening bolts, and a positioning clamping mechanism is installed below the protective lower cover.

[0007] Furthermore, the positioning and clamping mechanism includes a mounting base plate, which is fixedly installed below the protective lower cover and slidably installed on the side of the mounting frame. The mounting frame is configured as an "L" shaped structure, and the outer side wall of the mounting base plate is symmetrically provided with limiting T-shaped blocks.

[0008] Furthermore, the inner side wall of the mounting frame is symmetrically provided with two sets of limiting T-shaped grooves for sliding installation of the limiting T-shaped blocks. The top of the mounting base plate and the mounting frame are both provided with cylindrical grooves for the adjusting bolts to pass through, and an adjusting nut is rotatably installed below the adjusting bolts.

[0009] Furthermore, the outer surface of the adjusting nut at the rotating end is provided with vertical anti-slip texture, and the bottom outer wall of the mounting base plate and the top outer wall of the mounting bracket are both provided with elastic abutment pads.

[0010] This utility model has the following beneficial effects: 1. This utility model incorporates a spiral spring assembly. During device use, the spiral spring assembly enables the micro-pump extension tube to be designed as a retractable tube. This allows the extension tube to be adjusted according to the patient's actual medication needs, improving flexibility. Furthermore, the retractable extension tube can be shortened when not needed, reducing the risk of tangling and knotting during use. This maintains the patient's freedom of movement, providing better mobility and comfort, and allowing the patient to move more easily in daily life, reducing discomfort caused by intravenous infusion.

[0011] 2. By setting up an installation base plate and bolt adjustment assembly, this utility model allows the device to be positioned at any location on the bed according to the patient's actual medication pumping position requirements during use, without the device being completely encased inside the blanket. This ensures the stable placement of the device and guarantees the normal medication pumping of the micro-pump extension tube.

[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 Figures 1-5As shown, this utility model is a micro-pump extension tube with adjustable length, including a micro-pump extension tube body 1. The winding part of the micro-pump extension tube body 1 is located inside the cavity of the protective upper cover 101 and the protective lower cover 102, and both ends of the micro-pump extension tube body 1 are located outside the cavity. An auxiliary mounting plate 103 is fixedly installed on the inner wall of the bottom end of the protective lower cover 102, and a rotating part 104 is rotatably installed above the auxiliary mounting plate 103. A positioning post for installing the center end of the spiral spring 105 is provided at the center of the auxiliary mounting plate 103. The outer end of the spiral spring 105 is connected to the inner wall of the side of the rotating part 104, and the micro-pump extension tube body 1 is wound around the outside of the rotating part 104.

[0018] In the diagram, one side of the micro-pump extension tube body 1 has a fixed length, while the other side has a telescopic design. When it is necessary to pull the micro-pump extension tube body 1 out of the device to achieve the effect of extending the length, the adjustable-length micro-pump extension tube body 1 is pulled directly. When the micro-pump extension tube body 1 is pulled out of the device, the rotating part 104 rotates above the auxiliary mounting plate 103 and sends the micro-pump extension tube body 1 out of the protective lower cover 102. At the same time, due to the rotation of the rotating part 104, the spiral spring 105 installed inside it tightens and stores energy so that the micro-pump extension tube body 1 can be retracted into the device later. For the specific principle and structural composition of how to position the micro-pump extension tube body 1 at the specified extension length, please refer to the single-sided pull-out telescopic data cable. Example

[0019] Among them, such as Figures 3-4 As shown, the auxiliary disassembly mechanism 2 includes an abutment clip 201 and an abutment slot 202. The bottom outer wall of the protective upper cover 101 is provided with an abutment clip 201, and the top outer wall of the protective lower cover 102 is provided with an abutment slot 202 for the abutment clip 201 to be inserted and installed. The outer walls of the protective lower cover 102 located at the abutment slot 202 are symmetrically provided with two sets of positioning threaded grooves 203. The outer walls of the abutment clip 201 are symmetrically provided with two sets of mating threaded grooves 204. The positioning threaded grooves 203 and the mating threaded grooves 204 are threadedly installed with the fastening bolts 205.

[0020] When it is necessary to remove the protective cover 101 from the top of the protective cover 102 for maintenance, the fastening bolt 205 should first be completely unscrewed from the inside of the positioning threaded groove 203, so that the contact clip 201 changes from the locked state to the movable state. Then, the protective cover 101 and the contact clip 201 can be removed together. The installation is the same. Example

[0021] Among them, such as Figure 5As shown, the positioning and clamping mechanism 3 includes a mounting base plate 301, which is fixedly installed below the protective lower cover 102 and slidably installed on the side of the mounting frame 302. The mounting frame 302 is configured as an "L" shaped structure. The outer side wall of the mounting base plate 301 is symmetrically provided with limiting T-shaped blocks 303. The inner side wall of the mounting frame 302 is symmetrically provided with two sets of limiting T-shaped grooves 304 for sliding installation of the limiting T-shaped blocks 303. The top of the mounting base plate 301 and the mounting frame 302 are provided with cylindrical grooves for the adjusting bolts 305 to pass through, and the adjusting bolts 305 are rotatably installed below them.

[0022] When the device needs to be positioned and clamped next to the hospital bed, the mounting base plate 301 and mounting bracket 302 should first be clamped onto the upper and lower sides of the bed rail, respectively. Then, the adjusting bolt 305 should be passed through the two sets of cylindrical grooves inside the mounting base plate 301 and mounting bracket 302, and the adjusting nut 306 should be screwed onto the outside of the adjusting bolt 305 from bottom to top. After the adjusting bolt 305 is fully tightened, the mounting base plate 301 and mounting bracket 302 can be firmly positioned on the side of the bed rail. When the mounting base plate 301 moves, it will cause the limiting T-block 303 to slide inside the limiting T-slot 304. The setting of the limiting T-block 303 and the limiting T-slot 304 also provides a limiting support effect for the mounting base plate 301. Example

[0023] Among them, such as Figure 5 As shown, the outer surface of the adjusting nut 306 at the rotating end position is provided with vertical anti-slip texture, and the bottom outer wall of the mounting base plate 301 and the top outer wall of the mounting bracket 302 are both provided with elastic abutment pads 307.

[0024] The vertical anti-slip texture here allows the user to rotate the adjusting nut 306 more steadily by increasing the external contact friction. The elastic abutment pad 307 is designed to generate elastic deformation under compression, so that the mounting base plate 301 and mounting bracket 302 can be installed more steadily on the side of the guardrail.

[0025] One specific application of this embodiment is: In the figure, one side of the micro-pump extension tube body 1 is set to a fixed length, while the other side of the micro-pump extension tube body 1 is set to be telescopic. When it is necessary to pull the micro-pump extension tube body 1 out of the device to achieve the effect of extending the length, the adjustable length side of the micro-pump extension tube body 1 is pulled directly. When the micro-pump extension tube body 1 is pulled out of the device, the rotating part 104 rotates above the auxiliary mounting plate 103 and sends the micro-pump extension tube body 1 out of the protective lower cover 102. At the same time, due to the rotation of the rotating part 104, the spiral spring 105 installed inside it tightens and stores energy so that the micro-pump extension tube body 1 can be retracted into the device later. For the specific principle and structural composition of how to position the micro-pump extension tube body 1 at the specified extension length, please refer to the single-sided pull-out telescopic data cable. When the device needs to be positioned and clamped next to the hospital bed, the mounting base plate 301 and mounting bracket 302 should first be clamped onto the upper and lower sides of the bed rail, respectively. Then, the adjusting bolt 305 should be passed through the two sets of cylindrical grooves inside the mounting base plate 301 and mounting bracket 302, and the adjusting nut 306 should be screwed onto the outside of the adjusting bolt 305 from bottom to top. After the adjusting bolt 305 is fully tightened, the mounting base plate 301 and mounting bracket 302 can be firmly positioned on the side of the bed rail. When the mounting base plate 301 moves, it will cause the limiting T-block 303 to slide inside the limiting T-slot 304. The setting of the limiting T-block 303 and the limiting T-slot 304 also provides a limiting support effect for the mounting base plate 301.
