Description

Technical Field

[0001] The invention relates to the technical field of vaccines, in particular to an electric vaccine dosing device. Background Art

[0002] Vaccines refer to biological products made from various pathogenic microorganisms for vaccination. With the development of society, people know more and more about viruses. In order to improve the body's immunity to viruses, people will get multiple vaccines in their lifetime to improve people's resistance to related viruses. Nowadays, vaccines have become one of the important means to prevent and control infectious diseases. By getting the designated vaccines on time, you can effectively protect your health. When administering a vaccine, the original vaccine solution and diluent are usually sucked into a syringe, and then the needle is inserted into the human vein. The diluted vaccine is then injected into the human body. At this time, as the vaccine combines with the cells in the human body, antibodies to the specified type of virus are produced in the human body, which increases people's resistance to the virus, or even directly immunizes against the virus. The emergence of vaccines helps prevent diseases, reduce infection rates and the risk of complications. When vaccinating, medical staff usually manually pull the sealing plug of the syringe to absorb the vaccine concentrate and diluent through the negative pressure principle. When injecting the vaccine, medical staff usually need to gently push the sealing plug to squeeze part of the vaccine out of the syringe through the sealing plug. In this way, the air in the syringe is discharged. However, in actual operation, since it is all done manually and the operation is relatively delicate, it is easy for medical staff to make mistakes in controlling the force after working for a long time, resulting in excessive force and squeezing out too much vaccine, which causes too little vaccine in the syringe and easy waste of vaccine. For this reason, we propose an electric vaccine dosing device. Summary of the invention

The present invention installs a vaccine bottle and a disinfection bottle on a mounting seat. When vaccination is carried out, the baffle on the side of the vaccine bottle is driven to rotate by a knob to open the liquid inlet cavity on the side of the vaccine bottle. At this time, the vaccine liquid will enter the infusion cavity and then into the sleeve. When the vaccination is completed, the baffle on the side of the disinfection bottle is opened by a knob. At this time, the disinfectant will enter the infusion cavity through the liquid inlet cavity on the same side as the disinfection bottle, and enter the sleeve for disinfection, which effectively improves the timely disinfection of the sleeve by the device, and is convenient for subsequent recovery of the sleeve without causing pollution to the surrounding environment due to excessive residual vaccine inside.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-9 The present invention provides a technical solution: an electric vaccine dosing device, comprising a sleeve 1, a liquid storage chamber 13 is provided at one end of the sleeve 1, the sleeve 1 is made of transparent plastic material, a butt joint 12 is fixedly connected to the sleeve 1 away from the opening of the liquid storage chamber 13, a plurality of scale bars 11 are provided on the top of the sleeve 1, an end of the butt joint 12 away from the sleeve 1 is fixedly connected to a mounting seat 6, an end of the mounting seat 6 away from the butt joint 12 is fixedly connected to an infusion needle 66, and the infusion needle 66 is screwed on the mounting seat 6 through a spiral structure, so as to facilitate its subsequent disassembly and classification and recycling.

[0019] Furthermore, the sleeve 1 can store and mix the vaccine concentrate and diluent by setting up a liquid storage chamber 13. The scale bar 11 on the sleeve 1 can more intuitively know the specific milliliters of the vaccine in the current sleeve 1, further improving the auxiliary role of the device for medical personnel. When injecting the vaccine, the infusion needle 66 is inserted into the vein of the person to be vaccinated. Then, through the movement of the sealing plug 3, the vaccine will pass through the sleeve 1 into the docking tube 12, and then enter the mounting seat 6, and finally be discharged from the infusion needle 66 to complete the vaccine injection.

[0020] Combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, one end of the sleeve 1 away from the docking tube 12 is fixedly connected to the limit ring 2, and the limit ring 2 is fixedly connected to the limit seat 21. A limit hole 22 is provided on the side of the limit seat 21 close to the sleeve 1, and the limit rod 33 can be limited by the limit hole 22, so that the rack plate 34 on the limit rod 33 is always in a state of mutual meshing with the gear 23, and the limit rod 33 is more stable when moving. The gear 23 is rotatably connected in the limit seat 21, and the top of the limit seat 21 is fixedly connected to the motor 24, and the output end of the motor 24 is fixedly docked with the top of the rotating shaft of the gear 23. The bottom of the limit seat 21 is fixedly connected to the installation box 26, and the installation box 26 is provided with a control element and a lithium battery. A plurality of heat dissipation holes 27 are provided on one side of the installation box 26. By installing and controlling the elements in 26, medical personnel can better control the switch and rotation direction of the motor 24, and the lithium battery provides sufficient power to the motor 24 to enable it to operate normally. During the operation of the parts in the installation box 26, the heat generated inside will be discharged through the heat dissipation holes 27, so that the temperature in the installation box 26 will not be too high, causing damage to the electronic devices inside it. A sealing plug 3 is slidably connected in the liquid storage chamber 13 of the sleeve 1, and a limiting rod 33 is fixedly connected to the side of the sealing plug 3 close to the limiting seat 21. The limiting rod 33 is located in the limiting hole 22 and is slidably connected thereto. A rack plate 34 is fixedly connected to the side of the limiting rod 33 close to the gear 23, and the rack plate 34 and the gear 23 are meshed with each other, and the rack plate 34 and the gear 23 are meshed with each other. In the process of the motor 24 driving the gear 23 to rotate, the gear 23 and the rack plate 34 can cooperate to drive the limiting rod 33 to move, thereby completing the transmission of the sealing plug 3. A fixing ring 8 is fixedly connected to the sleeve 1, and a handle 81 is fixedly connected to the bottom of the fixing ring 8. A plurality of control buttons 82 for controlling the motor 24 are arranged on one side of the handle 81.

[0021] Furthermore, when performing a vaccine injection, the medical staff can first hold the handle 81 and control the motor 24 to start it through the control button 82. At this time, the motor 24 drives the gear 23 to rotate, and the rotating gear 23 cooperates with the rack plate 34 to drive the sealing plug 3 to move toward the sleeve 1 through the limit rod 33. At this time, the sealing plug 3 moves toward the docking tube 12, thereby applying pressure to the vaccine in the sleeve 1, so that the vaccine in the sleeve 1 is discharged through the infusion needle 66. The stable driving force of the motor 24 can make the amount of vaccine discharged from the infusion needle 66 more accurate. At this time, since a small amount of vaccine is discharged from the infusion needle 66, it means that the air in the infusion needle 66 is discharged. Then the infusion needle 66 is inserted into the patient's vein and injected again. Start the motor 24, and the sealing plug 3 is driven by the motor 24 to continuously move toward the docking tube 12. At this time, the sealing plug 3 applies pressure to the vaccine liquid in the sleeve 1, so that the vaccine is discharged from the infusion needle 66 and injected into the patient's vein, and the vaccine injection and medication work can be completed. When the vaccine liquid or disinfectant is delivered into the sleeve 1, the motor 24 is driven to rotate in the opposite direction through the control button 82. At this time, the gear 23 rotating in the opposite direction can cooperate with the rack plate 34 to drive the limit rod 33 and the sealing plug 3 to move toward the opening of the liquid storage chamber 13 of the sleeve 1. At this time, a negative pressure state will be formed in the sleeve 1, thereby absorbing the vaccine liquid and disinfectant, which is convenient for subsequent vaccine injection and tool disinfection.

[0022] Combined with Figure 3 , Figure 5 and Fig. 9As shown, a receiving groove 31 is provided on the side of the sealing plug 3 close to the butt joint 12, and a rubber ring 32 is fixedly connected to the surface of the sealing plug 3 close to the inner wall of the sleeve 1. The sealing plug 3 is provided with a rubber ring 32 on its surface, which can improve the sealing between the sealing plug 3 and the inner wall of the sleeve 1, and avoid the problem that the vaccine liquid flows out through the gap between the sealing plug 3 and the inner wall of the sleeve 1 after entering the sleeve 1. A turntable 4 is rotatably connected in the receiving groove 31, and a plurality of spiral guide plates 41 are fixedly connected to the side of the turntable 4 close to the butt joint 12. By arranging the plurality of guide plates 41 in a spiral shape, the guide plates 41 rotate together during the rotation of the turntable 4. At this time, the guide plates 41 cooperate with each other to stir the liquid in the sleeve 1, so that the vaccine liquid can be The liquid and the diluent are mixed more fully, and when the sleeve 1 is filled with disinfectant, the disinfectant is driven to flow in the sleeve 1 through the guide plate 41, thereby improving the efficiency of the disinfectant in the sleeve 1. The side of the turntable 4 away from the butt pipe 12 is fixedly connected with a screw 42, and the side of the limit seat 21 close to the screw 42 is fixedly connected with an internal threaded collar 25, the screw 42 is located in the internal threaded collar 25 and is threadedly connected thereto, and a limiting plate is provided at one end of the screw 42 away from the sealing plug 3, by which the problem of the screw 42 falling off from the internal threaded collar 25 can be prevented. By setting the screw 42, while the turntable 4 moves with the sealing plug 3, the screw 42 cooperates with the internal threaded sleeve 25 to make the screw 42 rotate, thereby driving the turntable 4 to rotate.

[0023] Furthermore, during the movement of the sealing plug 3, it can drive the turntable 4 and the screw 42 to move together. During the movement of the screw 42, since it is limited by the fixed internal threaded ring 25, the screw 42 will rotate synchronously when moving. At this time, the screw 42 will drive the turntable 4 to rotate, and the turntable 4 will drive the guide plate 41 thereon to rotate. During this process, the rotating guide plate 41 will rotate and stir the vaccine liquid and diluent located in the sleeve 1 to improve the mixing efficiency of the vaccine concentrate and the diluent. When the sleeve 1 is filled with disinfectant, the disinfectant will be stirred by the rotating guide plate 41, so that the disinfectant forms a flowing state in the sleeve 1, so that the disinfectant can be mixed with the residual vaccine liquid in the sleeve 1 more quickly, so that the disinfection effect of the disinfectant on the sleeve 1 is more obvious.

[0024] Combined with Figure 1 , Figure 3 and Figure 5As shown, one end of the limit rod 33 away from the sealing plug 3 is fixedly connected to a mounting frame 5, and the mounting frame 5 is located on the outside of the sleeve 1, and the side of the mounting frame 5 close to the sleeve 1 is fixedly connected to an indicating needle 51 for indicating the position of the scale bar 11, and the indicating needle 51 is located on the side of the sleeve 1 close to the scale bar 11. By the position of the scale bar 11 pointed by the indicating needle 51, the milliliter amount of the current vaccine liquid in the sleeve 1 can be more intuitively known.

[0025] Furthermore, during the movement of the limit rod 33, it will drive the mounting frame 5 to move synchronously. At this time, the mounting frame 5 will drive the indicator needle 51 to move along the outside of the sleeve 1. The specific milliliter volume of the vaccine liquid in the liquid storage chamber 13 can be intuitively known by the position of the scale bar 11 pointed by the indicator needle 51, thereby avoiding the traditional method of only marking the scale bar 11 on the sleeve 1, which leads to the problem that when the device is tilted, the milliliter volume of the vaccine liquid in the sleeve 11 is easily deviated by observing the scale bar 11 only.

[0026] Combined with Figure 1 , Figure 7 and Figure 8 As shown, an infusion cavity 61 for connecting the butt joint 12 and the infusion needle 66 is provided in the mounting seat 6, and two liquid inlet cavities 62 connected with the infusion cavity 61 are provided on the top of the mounting seat 6, and baffles 63 are rotatably connected in the liquid inlet cavities 62. Two knobs 65 are rotatably connected to one side of the mounting seat 6, and the knobs 65 are fixedly docked with one end of the rotating shaft of the baffle 63 on the same side thereof, and damping plates are provided between the knobs 65 and the mounting seat 6, and the friction between the knobs 65 and the mounting seat 6 can be increased by the damping plates to prevent the knobs 65 from rotating by themselves due to external force or accidental touch, and a rubber Pad 64, by arranging rubber pad 64 on baffle plate 63, the sealing performance of baffle plate 63 to liquid inlet cavity 62 can be improved, so as to avoid the problem that disinfectant enters into sleeve tube 1 during injection, causing damage to vaccine. The top of mounting seat 6 is respectively threadedly connected with vaccine bottle 7 and disinfection bottle 71, vaccine bottle 7 is filled with vaccine liquid, and disinfection bottle 71 is filled with disinfectant. By rotating baffle plates 63 at different positions, liquid inlet cavities 62 at different positions are opened, so that vaccine liquid or disinfectant can enter sleeve tube 1 respectively, and relevant vaccine injection or work is completed. The bottle mouths of vaccine bottle 7 and disinfection bottle 71 are respectively connected with liquid inlet cavity 62 on the same side thereof.

[0027] Furthermore, when performing vaccine injection, the knob 65 close to the side of the vaccine bottle 7 is rotated to drive the baffle 63 connected thereto to rotate, so that the liquid inlet cavity 62 on this side is opened. At this time, the vaccine liquid in the vaccine bottle 7 will enter the infusion cavity 61 through the liquid inlet cavity 62, and then the motor 24 drives the sealing plug 3 to move toward the opening of the liquid storage cavity 13. At this time, the sealing plug 3 moves to generate negative pressure in the liquid storage cavity 13, so that the vaccine liquid in the infusion cavity 61 can be sucked into the sleeve 1, and then the knob 65 is rotated in the opposite direction, and the liquid inlet cavity 62 is blocked by the baffle 63, and then the vaccine can be injected. The vaccine injection work is carried out. When the vaccine injection work is completed, the knob 65 near the side of the disinfection bottle 71 is turned to drive the baffle 63 connected thereto to rotate, so that the liquid inlet cavity 62 near the side of the disinfection bottle 71 is opened. At this time, the disinfectant in the disinfection bottle 71 will enter the infusion cavity 61 through the liquid inlet cavity 62, and then the sealing plug 3 is moved to drive the disinfectant 71 to flow in the sleeve 1. The impact force of the disinfectant 71 during flow flushes the inner wall of the sleeve 1, and then the disinfectant 71 is squeezed out from the infusion needle 66, thereby completing the preliminary disinfection in the sleeve 1, which is convenient for subsequent recovery.

[0028] Working principle: First, when performing vaccine injection, turn the knob 65 near the side of the vaccine bottle 7 to drive the baffle 63 connected thereto to rotate, so that the liquid inlet cavity 62 on this side is opened. At this time, the vaccine liquid in the vaccine bottle 7 will enter the infusion cavity 61 through the liquid inlet cavity 62, and the motor 24 is driven to rotate in the opposite direction through the control button 82. At this time, the gear 23 rotating in the opposite direction can cooperate with the rack plate 34 to drive the limit rod 33 and the sealing plug 3 to move toward the opening of the liquid storage cavity 13 of the sleeve 1. At this time, a negative pressure state will be formed in the sleeve 1, thereby absorbing the vaccine liquid and; Then, the knob 65 is rotated in the opposite direction, and the baffle plate 63 is used to block the liquid inlet chamber 62. Then, the vaccine injection work can be carried out. The motor 24 is controlled to start by the control button 82. At this time, the motor 24 drives the gear 23 to rotate. The rotating gear 23 cooperates with the rack plate 34 to drive the sealing plug 3 to move toward the sleeve 1 through the limit rod 33. At this time, the sealing plug 3 moves toward the docking tube 12, thereby applying pressure to the vaccine in the sleeve 1, so that the vaccine in the sleeve 1 is discharged through the infusion needle 66. At this time, a small amount of vaccine is discharged from the infusion needle 66, which means that the air in the infusion needle 66 is discharged. Then, the infusion needle 66 is inserted into the patient's vein, and the motor 24 is started again. At this time, the sealing plug 3 is driven by the motor 24 to continue to move toward the docking tube 12. At this time, the pressure applied by the sealing plug 3 to the vaccine liquid in the sleeve 1 causes the vaccine to be discharged from the infusion needle 66 and injected into the patient's vein, thereby completing the vaccine injection and administration work; When the vaccine injection is finished, the knob 65 near the disinfection bottle 71 is turned to drive the baffle 63 connected thereto to rotate, so that the liquid inlet cavity 62 near the disinfection bottle 71 is opened. At this time, the disinfectant in the disinfection bottle 71 will enter the infusion cavity 61 through the liquid inlet cavity 62, and then the disinfectant 71 is driven to flow in the sleeve 1 by moving the sealing plug 3. The inner wall of the sleeve 1 is flushed by the impact force of the disinfectant 71 during the flow, and then the disinfectant 71 is squeezed out from the infusion needle 66, so that the preliminary disinfection in the sleeve 1 can be completed, which is convenient for subsequent recovery; In specific operation, when the sealing plug 3 moves, it can drive the turntable 4 and the screw 42 to move together. During the movement of the screw 42, since it is limited by the fixed internal threaded ring 25, the screw 42 will rotate synchronously when moving. At this time, the screw 42 will drive the turntable 4 to rotate, and the turntable 4 will drive the guide plate 41 thereon to rotate. During this process, the rotating guide plate 41 will rotate and stir the vaccine liquid and diluent located in the sleeve 1 to improve the mixing efficiency of the vaccine concentrate and the diluent. When the sleeve 1 is filled with disinfectant, the disinfectant will be stirred by the rotating guide plate 41, so that the disinfectant forms a flowing state in the sleeve 1, so that the disinfectant can be mixed with the residual vaccine liquid in the sleeve 1 more quickly, so that the disinfection effect of the disinfectant on the sleeve 1 is more obvious.
