Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an infusion set for stroke emergency patients. Background Technology

[0002] Intravenous infusion is a common treatment method, with the infusion set utilizing gravity to deliver the fluid. Atmospheric pressure forces the fluid in the infusion bottle through the tubing into the drip chamber. When the pressure of the water column in the drip chamber exceeds the venous pressure, the fluid flows into the vein. Aseptically treated infusion devices establish a safe pathway between the vein and the medication. Stroke, also known as cerebrovascular accident, is an acute cerebrovascular disease caused by the blockage or rupture of blood vessels in the brain, leading to brain tissue damage and symptoms such as limb numbness, weakness, hemiplegia, aphasia, and altered consciousness. It has extremely high rates of disability and mortality. Timely and effective emergency treatment is crucial for reducing the mortality rate and alleviating the sequelae of stroke patients, and rapid, accurate, and safe intravenous infusion therapy is particularly critical in emergency situations.

[0003] Currently, infusion sets generally consist of an infusion bottle, infusion tubing, drip chamber, regulator, and needle. The infusion bottle stores the medication, the infusion tubing delivers the medication, the drip chamber buffers and monitors the drip rate, the regulator adjusts the drip rate according to the patient's condition, and the needle punctures the vein to allow the medication to enter the body. During infusion, medical staff will select the medication, determine the dosage and drip rate based on the patient's condition, age, and physical status, and will also regularly observe the infusion site for any abnormalities and address them promptly. Infusion devices are also equipped with safety features, such as air filters to prevent air embolism and flow regulators to ensure stable and accurate infusion.

[0004] However, current intravenous infusion technology still has shortcomings in dealing with special patients and special situations. Special patients, such as children, the elderly, and critically ill patients, have special physical conditions and high requirements for intravenous infusion. In public places or areas with scarce medical resources, patients receiving intravenous infusions may be unattended. Non-medical personnel coming into contact with the medication may contaminate the medication, affect its efficacy, and may also cause disputes. When patients lose consciousness, current devices lack body control and protective measures. Unconscious movements by the patient may pull on the infusion tubing, causing the needle to dislodge, interrupting the infusion, or even harming themselves or others. Utility Model Content

Detailed Implementation

[0041] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a full understanding of the implementation of embodiments of the present invention.

[0042] Existing infusion sets generally consist of an infusion bottle, infusion tubing, drip chamber, regulator, and needle. The infusion bottle stores the medication, the infusion tubing delivers the medication, the drip chamber buffers and monitors the drip rate, the regulator adjusts the drip rate according to the patient's condition, and the needle punctures the vein to allow the medication to enter the body. However, current infusion technology has shortcomings in dealing with special patients and situations. In public places or areas with limited medical resources, patients receiving infusions may be unattended, and non-medical personnel handling the medication could contaminate it, affect its efficacy, and potentially lead to disputes. When a patient is unconscious, existing devices lack body control and protective measures; unconscious movements by the patient may pull on the infusion tubing, causing the needle to dislodge, interrupting the infusion, or even injuring themselves or others.

[0043] To solve the above problems, refer to Figures 1-6 As shown, this embodiment provides an infusion set for stroke emergency patients, mainly including a fixing frame 1. The fixing frame 1 is designed as a multi-ring main frame, with a support frame 4 and a flexible tube 5 connected to the top of the inner wall. A fixing post 2 is provided on the inner side of the fixing frame 1. A thumb ring 3 is provided at the end of the fixing post 2 near the patient's hand, and a slow-release buckle 6 is provided at the end of the flexible tube 5 away from the support frame 4. The support frame 4 is placed inside the fixing frame 1 and is fixedly connected to the fixing post 2 to form a stable support structure. The flexible tube 5 is laid along the inner top wall of the fixing frame 1 and fixed to the support frame 4 by a snap-fit ​​method.

[0044] In this embodiment, the fixing frame 1 serves as the basic framework of the infusion set, providing stable support for the entire device. The cooperation between the support frame 4 and the fixing column 2 ensures the horizontal extension of the tubing 5, preventing swaying or displacement of the tubing 5 during infusion. The thumb ring 3 and the fixing frame 1 form a gripping area, allowing medical personnel to confine the patient's hand inside the fixing frame 1, preventing infusion errors caused by the patient's hand shaking. The tubing 5, as the drug delivery channel, is fixed to the support frame 4 by a snap-fit ​​mechanism, ensuring the stability of the tubing while facilitating disassembly and replacement.

[0045] Traditional infusion sets lack effective restraint devices for the patient's hand, making it easy for the patient's hand to shake and cause infusion errors. This embodiment addresses this by incorporating a gripping area formed by a thumb ring 3 and a fixing frame 1. Utilizing the stability of the fixing frame 1 and the restraining effect of the thumb ring 3, the patient's hand is fixed in a specific position, ensuring smooth infusion. This enhances the stability of the infusion set, prevents infusion errors caused by patient hand movement, facilitates operation by medical staff, and improves infusion efficiency.

[0046] In some embodiments of this application, the deceleration buckle 6 is located at the distal end of the fixing frame 1 and connected to one end of the hose 5. The deceleration buckle 6 includes a knob structure, which has a compression device inside that matches the hose 5.

[0047] When it is necessary to adjust the drug flow rate, medical staff can rotate the knob of the slow-release buckle 6 to apply different levels of pressure to the tubing 5. By changing the cross-sectional area of ​​the tubing 5, the drug flow rate can be finely adjusted, while also preventing backflow and ensuring infusion safety.

[0048] When the drug flow rate is not precisely adjusted, it is generally difficult to meet the physical needs of special patients. This embodiment achieves precise adjustment of the drug flow rate by setting a slow-release button 6, adapting to the needs of more special patients, improving the controllability of the infusion process, and enhancing the applicability of the infusion set.

[0049] In some embodiments of this application, the thumb ring 3 is a semi-circular ring structure located at one end of the fixing frame 1. The inner surface of the thumb ring 3 is provided with anti-slip texture to increase friction with the patient's palm. The angle of the connection end between the thumb ring 3 and the fixing frame 1 is adjustable to accommodate different hand shapes and sizes of patients.

[0050] Medical staff place the patient's palm within the gripping area formed by the thumb ring 3 and the fixation frame 1. By adjusting the connection angle between the thumb ring 3 and the fixation frame 1, the patient's palm is better restrained. The anti-slip textured design further increases friction with the patient's palm, preventing the hand from slipping. This effectively restrains the palm. Simultaneously, by adjusting the connection angle between the thumb ring 3 and the fixation frame 1, the applicability of the infusion set is improved, accommodating the needs of different patients with varying hand shapes and sizes.

[0051] In some embodiments of this application, the support frame 4 has a U-shaped structure, with its two ends fixed to the inner wall of the fixing frame 1. The support frame 4 has openings at both ends, and the flexible hose 5 passes through these openings and is snapped into place on the support frame 4.

[0052] The U-shaped structure of the support frame 4 provides stable support for the ring-shaped structure of the fixing frame 1, while also restricting the position of the tubing 5 to prevent displacement or shaking during infusion. The tubing 5 passes through the opening of the support frame 4 and is secured with the support frame 4, ensuring the stability of the tubing and facilitating disassembly and replacement, thus improving the maintenance efficiency of the infusion set. It also further enhances the stability of the infusion set, preventing infusion errors caused by tubing displacement or shaking.

[0053] In some embodiments of this application, the medicine storage tank 8 is located at the top of the infusion set and is a cylindrical, vertically placed structure used to hold and store the medicine to be infused. The bottom of the medicine storage tank 8 is securely connected to the first infusion tube 71 via a snap-fit ​​mechanism, ensuring that the medicine can flow steadily into the next stage. The end of the first infusion tube 71 away from the medicine storage tank 8 is connected to a drip chamber 13, which buffers and regulates the flow rate of the medicine, ensuring that the medicine can be dripped evenly and stably into the patient's body.

[0054] The drip chamber 13 is equipped with a dropper 14, which is connected to the first infusion tube 71 to introduce the medicine solution from the first infusion tube 71 into the drip chamber 13. The bottom of the drip chamber 13 is also equipped with a sealing ring 15, which is made of elastic material and can fit tightly to the bottom of the drip chamber 13 to effectively prevent the medicine solution from flowing back from the drip chamber 13, thus avoiding medicine contamination and waste.

[0055] The end of the drip chamber 13 furthest from the first infusion tube 71 is connected to a second infusion tube 72, which further delivers the medication. The second infusion tube 72 is connected to the end of the tubing 5 furthest from the slow-release buckle 6, and the tubing 5 is used to directly deliver the medication into the patient's body.

[0056] The slow-release buckle 6 can adjust the flow rate of the medication in the tubing 5 as needed to meet the infusion requirements of different patients. After the medication is stored in the storage tank 8, it flows naturally into the first infusion tube 71 by gravity, and then, after being buffered and regulated by the drip chamber 13, it drips through the dropper 14 into the lower closed ring 15, forming a stable drip. These drops then flow into the tubing 5 through the second infusion tube 72 and are finally administered to the patient. The design of the closed ring 15 not only effectively prevents the medication from flowing back into the drip chamber 13, but also improves the stability and safety of the entire infusion process.

[0057] This embodiment improves the storage capacity and stability of the medication by designing the medicine storage tank 8 as a cylindrical, vertically placed structure. Secondly, the design of the drip chamber 13 and the dropper 14 ensures that the medication is delivered evenly and stably to the patient, avoiding discomfort caused by excessively fast or slow flow rates. Furthermore, the closed-loop design 15 effectively prevents backflow of the medication, avoiding contamination and waste. Finally, the addition of the slow-flow buckle 6 allows medical staff to adjust the flow rate according to the patient's specific condition, improving the flexibility and safety of the infusion.

[0058] In some embodiments of this application, the regulator 16 is located below the drip chamber 13, making it easy to operate without interfering with the normal function of the drip chamber 13. One end of the regulator 16 is snapped into the end of the second infusion tube 72 away from the drip chamber 13. This snap-fit ​​connection ensures a secure connection that is not easily detached, while also facilitating quick assembly and disassembly. A rubber sealing ring 19 is provided at the connection point between the top of the regulator 16 and the second infusion tube 72. The main function of this sealing ring is to prevent liquid leakage from the connection point, thereby enhancing the sealing performance of the entire infusion system.

[0059] The other end of the regulator 16 is connected to the third infusion tube 73 via a connector. The third infusion tube 73 is directly connected to the end of the tubing 5 furthest from the slow-release buckle 6, making the infusion process smoother and reducing resistance in the infusion line. Simultaneously, the slow-release buckle 6 on the tubing 5 can adjust the infusion rate as needed, increasing the flexibility of the infusion system. The inner wall of the regulator 16 is specially designed with a moving groove 17, within which a pulley 18 is slidably mounted. The pulley 18 design makes adjusting the infusion rate with the regulator 16 easier and smoother, reducing friction during adjustment and improving the accuracy of the adjustment.

[0060] Furthermore, the pulley 18 can also reduce the impact on the infusion system caused by adjustment operations to a certain extent, protecting the integrity of the infusion tubing. In summary, the regulator 16 and its related structural design in this embodiment not only improve the stability and sealing of the infusion system, but also optimize the adjustment operation through the pulley 18, making the entire infusion process safer, more efficient, and more convenient.

[0061] In some embodiments of this application, the drip chamber 13 is a cylindrical transparent container located on the first infusion tube 71. The inner top wall of the drip chamber 13 is vertically and fixedly connected to the dropper 14. This design ensures that the drip chamber 13 can stably receive and store the medication flowing in from the first infusion tube 71. The sealing ring 15 is made of silicone, and its outer diameter is press-fitted with the inner wall of the drip chamber 13 to form a tight connection, effectively preventing medication leakage.

[0062] After the medication flows into the drip chamber 13 from the first infusion tube 71, it drips at a steady rate through the dropper 14 into the lower closed ring 15. The interference fit between the closed ring 15 and the inner wall of the drip chamber 13 not only ensures the smooth dripping of the medication but also forms an effective seal, preventing backflow and avoiding waste and potential contamination. Medical staff can monitor the drug flow rate by observing the dripping situation in the drip chamber 13. This intuitive and real-time monitoring method significantly improves the controllability of the infusion process.

[0063] In some embodiments of this application, the movable groove 17 of the regulator 16 is a strip-shaped groove located on the inner sidewall of the regulator 16. A pulley 18 is located within the movable groove 17 and can slide freely within it. This design allows medical personnel to easily adjust the cross-sectional area of ​​the lumen of the third infusion tube 73 by sliding the pulley 18. A rubber sealing ring 19 covers the joint between the regulator 16 and the third infusion tube 73, enhancing the seal between them.

[0064] When it is necessary to adjust the drug flow rate, medical staff only need to slide the pulley 18 within the moving groove 17 to change the cross-sectional area of ​​the lumen of the third infusion tube 73, thereby achieving precise control of the drug flow rate. The sliding of the pulley 18 adjusts the drug flow rate by pressing or releasing the third infusion tube 73; the operation is simple and the effect is significant. The design of the rubber sealing ring 19 further ensures the sealing between the regulator 16 and the third infusion tube 73, effectively preventing drug leakage and contamination, and improving the controllability and safety of the infusion process.

[0065] In some embodiments of this application, the top of the medicine storage tank 8 is provided with a threaded top cover 9. This design allows the top cover 9 to be easily connected to the top of the medicine storage tank 8 via a thread, facilitating the opening and closing of the medicine storage tank 8 to add or remove the medicine. A protective disc 10 is fixed to the top of the top cover 9, and the top cover 9 and the protective disc 10 are coaxially arranged. The protective disc 10 is used to prevent dust or foreign objects from falling into the medicine storage tank 8, ensuring the purity of the medicine.

[0066] The top of the medicine storage tank 8 is also equipped with a hanging ring 11. The ring 11 is a ring-shaped metal structure that is sturdy and durable, making it easy for medical personnel to carry and operate the infusion set. The bottom of the medicine storage tank 8 is equipped with a sealing cap 12, which is connected to the medicine storage tank 8 by a threaded seal to ensure the airtightness of the medicine solution and prevent leakage and contamination.

[0067] In some embodiments of this application, a needle assembly is also included, comprising a suction tube 20, a specification label 21, and a needle 22. One end of the suction tube 20 is connected to a slow-release buckle 6, and the other end is fixedly connected to the needle 22 via the specification label 21. The suction tube 20 is a transparent flexible tube, a design that allows medical personnel to visually observe the flow of the medication, ensuring the smooth progress of the infusion process.

[0068] Specification label 21 is a flat piece with graduations, used to indicate the specifications of the infusion set and the dosage of medication, facilitating accurate infusion information for medical staff. After the medication flows from the tubing 5 into the suction tube 20, it is administered to the patient through specification label 21 and needle 22. The transparent design of the suction tube 20 and the graduations on specification label 21 together enhance the practicality and reliability of the infusion set.

[0069] As can be seen from the above embodiments, the working steps of the infusion set for stroke emergency patients provided in this application are as follows:

[0070] First, medical staff will place a restraint brace on the patient's arm to restrict movement and prevent secondary injury during the infusion process. Next, a thumb ring will be placed over the patient's hand to prevent the needle from dislodging due to movement. Then, the medical staff will check for foreign objects in the infusion tubing and tubing, and verify that the medicine tank, drip chamber, and regulator are connected by the infusion tubing. They will also check that the tubing connected to the bottom of the regulator is connected to the tubing and that the specifications are correct. Once all checks are completed and found to be normal, the top cap will be opened by rotating it. The medication will then be placed in the medicine tank. The flow rate can be monitored through the drip chamber; if the flow rate is abnormal, it can be adjusted using the regulator. Finally, the medication will flow through the tubing until it reaches the needle. If medication is observed flowing from the needle, the needle can be inserted into the patient to begin the infusion.

[0071] The intravenous infusion set for stroke emergency patients provided in this application features a fixed frame and a fixed post, which makes the device more secure when restricting the patient's arm, preventing damage to the device and secondary injury. The fixed frame and the thumb ring help medical staff to more easily restrict the patient's palm during infusion, avoiding infusion errors caused by the patient's hand shaking. The fixed frame, tubing, and support frame allow medication to be delivered through the tubing, and the support frame protects the tubing from compression during medication delivery, preventing delivery difficulties. The support frame also restricts the position of the tubing, facilitating infusion by medical staff. The tubing and the slow-release buckle effectively limit the drug flow rate, reducing the flow rate and preventing backflow.

[0072] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the disclosure in the specification and the embodiments. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
