Description

Technical Field

[0001] The utility model relates to the technical field of infusion tube adjustment, in particular to a novel catheter type fine adjustment for infusion. Background Technique

[0002] An infusion tube is a medical device used to deliver liquid drugs or nutritional solutions into a patient's body. It is usually made of soft materials such as polyvinyl chloride (PVC) or silicone, and has certain flexibility and durability.

[0003] However, in actual use, there are still the following deficiencies. For example, there are two mainstream infusion tube fine adjustment technologies on the market, namely flow channel type fine adjustment and catheter type fine adjustment. Among them, flow channel type fine adjustment is suitable for scenarios that require a wide range of flow rate adjustment, but is sensitive to temperature changes. While catheter type fine adjustment provides more precise flow control, but may require a trade-off between cost and design complexity. For different medical needs and application scenarios, choosing the appropriate fine adjustment technology can effectively improve the performance and safety of the infusion tube.

[0004] Therefore, the utility model provides a novel catheter type fine adjustment for infusion. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and provide a novel catheter type fine adjustment for infusion.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a novel catheter type fine adjustment for infusion, including an infusion tube, an infinitely variable adjustment component is fixedly connected to the outside of the infusion tube, and a heating component is fixedly connected to the top end of the infinitely variable adjustment component;

[0007] The infinitely variable adjustment component includes a box body, the inside of the box body is fixedly connected to the infusion tube, a regulating rotating column is rotatably connected to the inner wall of the box body, a sealing ring is fixedly connected to the top end of the regulating rotating column, a rotating handle is fixedly connected to the top end of the regulating rotating column, positioning blocks are fixedly connected to both sides of the inner wall of the box body, an adjusting slider is slidably connected to the inner wall of the box body, and elastic pieces are fixedly connected to one ends of the positioning blocks close to the regulating rotating column.

[0008] As a preferred implementation manner, the heating component includes a top cover, the bottom end of the top cover is fixedly connected to the top end of the box body, a sealing column is fixedly connected to the top end of the top cover, protective sleeves are fixedly connected to both sides of the box body, a constant temperature cavity is opened inside the box body, and an adhesive is fixedly connected to the bottom end of the box body.

[0009] The technical effects of adopting the above technical solution are as follows: on the one hand, it can achieve stepless speed regulation of the flow rate like the flow channel type fine adjustment; on the other hand, its flow rate can be controlled more accurately than that of the flow channel type fine adjustment, and the input liquid is heated to improve the comfort of infusion.

[0010] As a preferred embodiment, one end of the elastic piece away from the positioning block is fixedly connected to the adjusting slider.

[0011] The technical effect of adopting the above technical solution is: to ensure that the elasticity of the elastic piece can be transmitted to the adjusting slider.

[0017] The technical effect of adopting the above technical solution is: to achieve overall sealing.

[0018] Compared with the prior art, the advantages and positive effects of the present utility model are as follows;

[0019] The present utility model is based on an infusion tube by setting a stepless adjustment component and a heating component structure to ensure the smooth flow of the liquid. The adjusting rotating column cooperates with the handle to drive the slider to accurately displace under the action of the positioning block and the elastic piece, controlling the flow rate and flow volume. The positioning block and the elastic piece ensure the stable transmission of force, and the slider moves smoothly. After the rotating column releases the pressure, the elastic piece makes the slider rebound. When heating, hot water is injected into the through hole of the top cover, and the sealing column is engaged to prevent leakage. After tearing off the back glue, the mixture in the constant temperature cavity generates heat through the oxidation of iron powder, the heat release of salt dissolution, and the heat conductivity of activated carbon to maintain a constant temperature. Such a design can accurately adjust the displacement of the adjusting slider, achieve fine adjustment of the liquid flow rate and flow volume, and achieve the effect of constant temperature when heating the infusion liquid, providing a more comfortable infusion process. In this way, not only the problem that the flow channel type fine adjustment is sensitive to temperature changes is solved, but also the cost and design complexity of the catheter type fine adjustment are optimized.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] As Figure 1 - Figure 4 shown, this embodiment provides a technical solution: A novel catheter - type fine - tuning for infusion, including an infusion tube 1. The outer side of the infusion tube 1 is fixedly connected with a stepless adjustment component 2, and the top end of the stepless adjustment component 2 is fixedly connected with a heating component 3. First, the infusion tube 1 serves as the basis of the overall structure to ensure the smooth flow of the liquid. The function of the stepless adjustment component 2 is to allow the user to precisely control the flow rate and flow volume of the liquid through adjustment. The heating component 3 can heat the infusion liquid when needed to increase the temperature of the liquid to improve the comfort of infusion;

The inside of the box body 21 is fixedly connected to the infusion tube 1 to ensure a firm connection and stability. There is an adjustment rotating column 22 on the inner wall of the box body 21. The function of this rotating column is to control the liquid flow rate through rotation adjustment. The top end of the adjustment rotating column 22 is fixedly connected with a sealing ring 23, which ensures that no liquid leakage occurs during the adjustment process and maintains the safety of the system. First of all, the box body 21 is the core of the overall structure, and its inside is fixedly connected to the infusion tube 1 to ensure the stability and fixity of the infusion tube 1. The adjustment rotating column 22 allows the user to control the flow rate and flow volume of the liquid by adjusting its position. The sealing ring 23 is to ensure that no liquid leakage occurs during the adjustment process and maintain the safety and stability of the entire device. The rotating handle 24 is the interface for user operation. By rotating the rotating handle 24, the hand can achieve fine-tuning of the flow rate and flow volume, making the infusion process more accurate. The function of the positioning block 25 is to ensure the correct position of the adjustment slider 26 inside the box body 21 and prevent it from shifting or detaching due to external forces. And the adjustment slider 26 cooperates with the positioning block 25 and the elastic sheet 27 to ensure that the force of the adjustment rotating column 22 can be stably transmitted. The elastic sheet 27 provides additional feedback force and stable support, making the movement of the adjustment slider 26 smoother and more controllable;

[0031] To solve the discomfort caused by the relatively cold liquid to the human body during infusion, such as Figure 1 - Figure 3As shown: In this solution, the heating component 3 includes a top cover 31. The top end of the sealing ring 23 is fixedly connected to the bottom end of the top cover 31. The bottom end of the top cover 31 is fixedly connected to the top end of the box body 21. A sealing column 32 is fixedly connected to the top end of the top cover 31. The outside of the sealing column 32 is engaged with the groove at the top end of the top cover 31. Protective sleeves 33 are fixedly connected to both sides of the box body 21. The inner wall of the protective sleeve 33 is fixedly connected to the outside of the infusion tube 1. A constant temperature chamber 34 is provided inside the box body 21. An adhesive 35 is fixedly connected to the bottom end of the box body 21. First, the top cover 31 is fixedly connected to the top end of the box body 21. The bottom end of the sealing ring 23 is closely connected to the bottom end of the top cover 31 to ensure the safety and sealing of the heating component 3.

The engagement of this sealing column 32 with the groove at the top end of the top cover 31 further enhances the sealing when hot water is added to the box body 21, preventing liquid leakage. The protective sleeve 33 provides an additional protective layer to prevent damage caused by friction between the infusion tube 1 and the box body 21. The constant temperature chamber 34 is used to accommodate specific mixtures such as iron powder, salt, and activated carbon to achieve a constant heating effect. When the adhesive 35 is torn off, the role of these mixtures is to generate heat and maintain a specific constant temperature state through the oxidation reaction of iron powder, the heat release from the dissolution of salt, and the thermal conductivity of activated carbon. And the adhesive 35 can prevent it from being stably placed at a stable support point.

[0032] Working principle:

[0033] As Figure 1 - Figure 4 shown:

[0034] When in use: First, the infusion tube 1 serves as the basis of the overall structure to ensure the smooth flow of liquid in the tube. Subsequently, through the cooperation of the internally fixed adjustment rotating column 22 and the rotating handle 24, the adjustment slider 26 is driven to perform precise displacement under the coordinated action of the positioning block 25 and the elastic piece 27, thereby achieving precise control of the liquid flow rate and flow volume. The settings of the positioning block 25 and the elastic piece 27 ensure that the force of the adjustment rotating column 22 can be stably transmitted, making the movement of the adjustment slider 26 smoother and more controllable. When the adjustment rotating column 22 releases the pressure on the adjustment slider 26, the adjustment slider 26 can be rebounded by the elastic piece 27. When it is necessary to heat the infusion liquid, first, hot water is injected through the through-hole on the top cover 31. Subsequently, the sealing column 32 is engaged with the through-hole at the top end of the top cover 31 to prevent liquid leakage. At this time, when the adhesive 35 is torn off, the mixture in the constant temperature chamber 34 generates heat and maintains a specific constant temperature state through the oxidation reaction of iron powder, the heat release from the dissolution of salt, and the thermal conductivity of activated carbon.
