Description

Technical Field

[0001] The utility model relates to the technical field of medicine mixing equipment in medical instruments, in particular to a medicine mixer with the functions of preventing misoperation and single-step installation. Background Art

[0002] In the field of medical devices, especially in the use of drug mixers, traditional designs usually include multiple steps, requiring medical staff to perform complex assembly before mixing and injection.

[0003] These operation steps are cumbersome and prone to misoperation, especially in emergency situations or high-frequency use scenarios, which makes the user experience extremely inconvenient. In addition, the common drug mixers in the prior art often lack effective anti-reverse installation devices in design, which can easily lead to reverse assembly of the drug mixer module, thus causing safety hazards and usage failures. For example:

[0004] 1. The complexity of multi-step operations still exists, and it is difficult for medical staff to quickly assemble the drug mixer in an emergency, resulting in waste of drug solution and operation delays.

[0005] 2. The existing drug mixers are not designed to prevent reverse installation. Users may install the drug mixer module in reverse due to improper operation during assembly. Although some designs introduce markings and prompts to help with correct installation, the problem of reverse assembly cannot be completely avoided, affecting the safety and reliability of use.

[0006] 3. Although the buckle design of the existing drug mixer can maintain a good locking effect in a static state, in actual use, due to frequent operation and high-pressure injection, the drug mixer head may still become loose or fall off. In order to ensure the safety and effectiveness of the mixed drug solution, the existing technology has also tried a variety of locking structures, but the design of these structures is complex, which increases the difficulty and cost of operation.

[0007] 4. Existing mixer designs also face challenges in terms of maintenance and cleaning. Traditional mixers are usually disposable and lack a detachable and reusable design, which makes the equipment prone to clogging during use, increasing the cost of use and the environmental burden. Although some designs have tried to introduce a removable structure, its complexity and inconvenience in operation make the actual application effect poor.

[0008] Therefore, how to simplify the operation process of the medicine mixer and improve the safety and reliability during the assembly process has become a technical problem to be solved by the utility model. Utility Model Content

[0013] The medicament mixing head module includes an upper end face guide groove, a connecting column hole, a clamping arm, and a lower end face threaded connection port.

[0014] The lower end face threaded connection port includes, but is not limited to, an inner Luer threaded connection port.

[0015] The clamping arm has a groove hole and a guiding inclined surface, and the guiding inclined surface is used to guide the cooperation between the clamping arm and the clamping bolt when the medicament mixing head module slides.

[0016] During the sliding process, the clamping arm cooperates with the clamping bolt through the guiding inclined surface, and the clamping arm undergoes elastic deformation and slides into the groove hole of the clamping bolt to form a locking structure.

[0017] The guide grooves and the clamping arms of the housing of the medicament mixer and the medicament mixing head module are designed to cooperate with each other, so that the user only needs to push the medicament mixing head module along the direction of the guide groove to complete the single-step operation installation of the medicament mixing head module.

[0018] As a further solution of the present utility model, the housing of the fixed module includes an asymmetric design to limit the installation direction of the medicament mixing head module through different heights and positions to ensure prevention of reverse assembly.

[0019] As a further solution of the present utility model, the distance between the inner sides of the clamping arms is less than the distance between the inner sides of the guide grooves, so that structural interference will occur during reverse assembly to prevent incorrect assembly.

[0020] As a further solution of the present utility model, two guiding inclined surfaces are provided on the clamping arm to guide the clamping bolt to slide into the groove hole, and a structure with increased thickness is provided on the clamping arm to enhance its strength.

[0021] As a further solution of the present utility model, the upper end face guide groove of the medicament mixing head module is connected by two U-shaped ribs. The U-shaped ribs present a semi-surrounding state, the top is open and hollow, and a clamping arm is provided at the hollow position.

[0022] As a further solution of the present utility model, the lower end surface of the mixing head module is provided with an inner Luer thread connection port for connecting a spray head, and the mixing head module and the syringe tip are sealed by slope fitting and snap locking.

[0023] As a further solution of the present utility model, the connection between the mixing head module and the fixing module can be elastically deformed when an external force is applied, enabling the mixing head module to be repeatedly disassembled and replaced.

[0024] As a further solution of the present utility model, two connection column holes are provided on the upper end surface of the mixing head module. The connection column holes are hollow cylinders matching Luer heads, and the lower end surface of the mixing head module has two independent flow channels for mixing liquid medicine at the outlet position.

Compared with existing mixers that require multiple steps of operation, the user experience is more friendly, especially suitable for medical staff in emergency or high-frequency use scenarios.

[0027] 2. Double locking and guiding design: The double locking structure between the mixing head module and the fixing module ensures that the mixing head does not fall off during injection through the cooperation of the snap arm and the clamping bolt. The double-layer guiding design of the guide groove and the guide rail further guarantees the installation accuracy and stability of the mixing head. Compared with the prior art, the present utility model has been significantly improved in terms of safety and reliability.

[0028] 3. Anti-reverse installation design: The asymmetric design of the fixing module shell restricts the mixing head module to be installed in the correct direction only through different heights and positions, effectively preventing failures and potential risks caused by reverse assembly.

[0029] 4. Repeated disassembly design: The connection between the mixing head module and the fixing module can be repeatedly disassembled and replaced through elastic deformation, solving the possible blockage problem of the mixer during use, extending the service life of the device, and improving the economy and maintenance convenience. Compared with traditional disposable or difficult-to-maintain mixers, the present utility model provides higher usage flexibility.

[0030] 5.

[0042] The housing 3 of the fixing module 1 includes an asymmetric design to ensure the installation direction of the medicine mixing head module 2 is restricted by different heights and positions to prevent reverse assembly. The distance between the inner sides of the clamping arms 7 is less than the distance between the inner sides of the guide grooves, so that structural interference will occur during reverse assembly to prevent incorrect assembly. There are two guiding inclined surfaces 15 provided on the clamping arm 7 to guide the clamping bolt 4 to slide into the groove hole 9, and a structure with increased thickness is provided on the clamping arm 7 to enhance its strength.

[0049] Embodiment 1:

[0050] This embodiment details the implementation manner of a medicine mixer with anti-misoperation and single-step installation functions in a specific application scenario, demonstrating the actual application effect of the technical solution of the present utility model in the medical scenario.

[0051] In a modern medical environment, medical staff often need to quickly and accurately mix drugs and inject them in emergency situations. The operation steps of traditional medicine mixers are cumbersome and prone to misoperation. Especially in emergency situations, the complex assembly process and the lack of an effective anti-reverse installation design pose great challenges to medical staff, which may lead to waste of liquid medicine and delay in treatment.

[0052] To solve these problems, the present utility model provides a medicine mixer with anti-misoperation and single-step installation functions. Its specific implementation manner is as follows:

[0053] In the emergency room, medical staff need to quickly inject a drug that needs to be mixed on-site for a patient. Using the medicine mixer of the present utility model, medical staff first provide a fixing module 1, which includes a housing 3 provided with a guide groove 14 extending in the Z direction and a clamping bolt 4 provided at the middle position of the housing 3. At the same time, a medicine mixing head module 2 is provided, which includes an upper end face guide groove 5, a connecting column hole 6, a buckle arm 7, and a lower end face inner Luer thread connection port 8. The buckle arm 7 has a groove hole 9 and a guiding inclined surface 15.

[0054] During the operation, medical staff align the mixing head module 2 with the guide groove of the fixing module 1. By sliding the mixing head module 2 along the direction of the guide groove, the buckle arm 7 is engaged with the clamping bolt 4. The guiding inclined surface 15 guides the buckle arm 7 to contact the clamping bolt 4, causing the buckle arm 7 to elastically deform and slide into the groove hole 9 of the clamping bolt 4, forming a stable locking structure. The whole process only requires one step, significantly simplifying the operation process.

[0055] Through the single-step blind installation operation design of the present utility model, medical staff can complete the installation of the mixing head module 2 without performing complex multi-step operations, significantly reducing the risk of misoperation and improving the operation efficiency. After the installation of the mixing head module 2 is completed, the mixing head module 2 is connected to the spray nozzle 12 through the internal Luer thread connection port 8 on the lower end surface to ensure a tight connection and prevent liquid medicine leakage.

[0056] In addition, the outer shell 3 of the fixing module 1 adopts an asymmetric design. By restricting different heights and positions, it ensures that the mixing head module 2 can only be installed in the correct direction, preventing the problem of reverse assembly and further improving the safety and reliability of use. During the disassembly process, medical staff only need to apply an external force to elastically deform the connection between the mixing head module 2 and the fixing module 1, and then the mixing head module 2 can be repeatedly disassembled and replaced, which is convenient for cleaning and maintenance.

[0057] The double locking and guiding structure of the present utility model ensures that the mixing head will not loosen or fall off during the injection process through the cooperation of the buckle arm 7 and the clamping bolt 4, providing a reliable locking effect. The double sealing design ensures the safety and effectiveness of the liquid medicine during the injection process through the slope fitting and buckle locking between the mixing head module 2 and the tip of the syringe 13, preventing liquid medicine leakage and enhancing the safety and reliability of the product.

[0058] In summary, in the application scenario of the emergency room, the guiding buckle mixer of the present utility model, through innovative designs such as single-step blind installation operation, anti-reverse installation design, repeatable disassembly structure, and double sealing, significantly simplifies the operation process, improves the safety and reliability of the operation, solves many problems existing in the use of traditional mixers, and provides a highly efficient, safe, and reliable mixing solution for medical staff.

[0059] Embodiment 2:

[0060] In the emergency room or ward, medical staff need to quickly prepare a syringe 13 with a mixed drug for the patient. The traditional mixer design often requires multiple steps for assembly, and problems such as waste of liquid medicine due to excessive force or complex operation are likely to occur, affecting the efficacy and treatment efficiency. The guiding buckle mixer of the present utility model provides a simplified solution.

[0061] In actual use, medical staff first take out the fixing module 1 and the medicine mixing head module 2. The fixing module 1 includes a housing 3 provided with a guide groove 14 extending in the Z direction and a clamping bolt 4 provided at the middle position of the housing 3. The medicine mixing head module 2 includes an upper end face guide groove 5, a connecting column hole 6, a clamping arm 7 and a lower end face inner Luer thread connection port 8. The clamping arm 7 has a groove hole 9 and a guiding inclined surface 15.

[0062] Medical staff fix the syringe 13 filled with liquid medicine in the housing 3 of the fixing module 1 and ensure that the tip of the syringe 13 is aligned with the connecting column hole 6 of the fixing module 1. At this time, the two column holes of the medicine mixing head module 2 are exactly aligned with the tip of the syringe 13. Then, medical staff slide the medicine mixing head module 2 along the direction of the guide groove, making it gradually approach the tip of the syringe 13. The guiding inclined surface 15 guides the clamping arm 7 to contact the clamping bolt 4, and the clamping arm 7 will undergo elastic deformation when it contacts the clamping bolt 4 and slide into the groove hole 9 of the clamping bolt 4, thus achieving locking.

[0063] During this process, the cooperation between the guide groove and the guide rail ensures the precise positioning and smooth sliding of the medicine mixing head module 2. Under the guidance of the guide rail, the medicine mixing head module 2 accurately slides into the tip position of the syringe 13, and through the cooperation between the groove hole 9 of the clamping arm 7 and the clamping bolt 4, a stable locking structure is formed. The entire assembly process only requires one step, simplifying the operation process and reducing the possibility of misoperation.

[0064] During the installation process, the housing 3 of the fixing module 1 through an asymmetric design ensures that the medicine mixing head module 2 can only be installed in the correct direction, preventing reverse assembly. The tip of the syringe 13 and the connecting column hole 6 of the medicine mixing head module 2 form a sealing structure to ensure that the liquid medicine does not leak.

[0065] If it is necessary to replace the medicine mixing head module 2, medical staff only need to apply an external force in the Z direction to make the clamping arm 7 undergo elastic deformation and disengage from the clamping bolt 4, and then the medicine mixing head module 2 can be easily pulled out. This repeatable disassembly design not only facilitates the cleaning and maintenance of the device but also solves the usage problems caused by the blockage of the medicine mixing head.

[0066] Through the guiding and clamping medicine mixer of the present utility model, medical staff can quickly and accurately complete the assembly of the medicine mixer, significantly improving work efficiency and operation safety. The double locking and guiding structure ensure the stability and reliability of the medicine mixing head during the injection process, prevent the leakage of liquid medicine, and improve the treatment effect. The asymmetric design and the repeatable disassembly structure further enhance the usability and maintainability of the product, providing an efficient, safe and reliable medicine mixing solution.
