Technical Field

[0001] The invention belongs to the technical field of drug injection, in particular to a rapid injection device for drugs for treating acute coronary syndrome. Background Art

[0002] The rapid injection device for treating acute coronary syndrome drugs is a medical device specifically used to quickly and accurately inject therapeutic drugs into the patient's body in the emergency treatment scenario of acute coronary syndrome (ACS). Its main function is to use a specific mechanical or power structure to allow the drug to enter the patient's blood circulation system through the vein or other appropriate administration routes in a short time at a speed and dosage that meets the treatment requirements, so as to quickly relieve ACS symptoms and save the patient's life.

[0003] Traditional rapid injection devices for treating acute coronary syndrome drugs have shortcomings in the replacement of injection needles. Usually, the connection between the injection needle and the injection tube is relatively simple and lacks an effective stabilization mechanism. In actual use, especially when injection operations are frequently performed or in more complex medical environments, such as emergency sites, mobile medical vehicles, etc., the injection needle is easily loosened or even falls off due to external interference. This will not only prevent the drug from being accurately and continuously injected into the patient's body, affecting the treatment effect, but may also cause drug leakage, posing potential risks to the health of medical staff and patients. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention promotes the connection sleeve to move in the direction of the injection tube by arranging the cooperation of structures such as the auxiliary sleeve and the replacement part.

[0019] The present invention controls the electric slider to slide on the electric slide rail through the setting of the quantitative mechanism, so that the feed port of the quantitative tube is aligned with the feed tube, and the medicine in the storage bin flows into the quantitative tube through the feed tube. When the medicine in the quantitative tube reaches the required dose, the feed is stopped, and the electric slider is controlled to slide again, so that the sealing part of the quantitative tube contacts the feed tube. At this time, the feed port at the top of the quantitative tube is closed, and the rotary cover at the bottom of the quantitative tube is released from contact with the baffle, and the rotary cover rotates, so that the medicine in the quantitative tube can flow into the inside of the injection tube. The feed port of the quantitative tube is controlled to align with the feed tube, so that the medicine flows from the storage bin into the quantitative tube, and the feed is stopped when the medicine in the quantitative tube reaches the required dose. This design can accurately control the amount of medicine injected each time, and avoid medical problems caused by excessive or insufficient drug doses. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] 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.

[0029] like Figures 1 to 7 As shown, the present invention provides a rapid injection device for treating acute coronary syndrome, comprising an injection tube 1, on which a replacement part 2 and a quantitative mechanism 3 are respectively installed;

[0030] The replacement part 2 includes a limiting groove 21, a moving block 22, a limiting spring 23, a connecting sleeve 24 and an injection needle 25. The moving block 22 moves inside the limiting groove 21. The limiting spring 23 is fixedly connected to one end of the moving block 22. The injection needle 25 is fixedly connected to one end of the connecting sleeve 24.

[0031] The quantitative mechanism 3 includes a feed tube 31, a quantitative tube 32, an electric slide rail 33 and a baffle 34. The feed tube 31 is located above the quantitative tube 32. The bottom surface of the quantitative tube 32 is fixedly connected with an electric slider 35, and the electric slider 35 is slidably connected to the electric slide rail 33. The baffle 34 is fixedly connected between the two electric slide rails 33.

[0032] The above scheme is adopted: the limiting grooves 21 are opened on both sides of the auxiliary sleeve 101 to provide a moving track for the moving block 22, limit the movement direction of the moving block 22, so that the replacement process of the injection needle 25 can be carried out on a predetermined path, and the stability and accuracy of the operation are guaranteed. The moving block 22 moves in the limiting groove 21 and cooperates with the limiting spring 23 to achieve the fixation and release of the connecting sleeve 24 and the injection needle 25. When the injection needle 25 needs to be replaced, the moving block 22 can move under the external force to change the connection state with the connecting sleeve 24. One end of the limiting spring 23 is connected to the moving block 22, and the other end is connected to the fixing plate 26. Its function is to provide The elastic force of the spring makes the moving block 22 maintain a fixed position on the connecting sleeve 24 under normal conditions, ensuring that the injection needle 25 will not accidentally fall off during use. When the injection needle 25 needs to be replaced, the moving block 22 can release the connecting sleeve 24 by overcoming the elastic force of the spring. The connecting sleeve 24 connects the injection needle 25 and the auxiliary sleeve 101, and is a fixed carrier of the injection needle 25. The accommodating grooves 241 on both sides are used to accommodate the limiting spring 23, the moving block 22 and other components, making the structure more compact. At the same time, the connecting sleeve 24 is connected with the injection needle 25 to ensure that the drug can smoothly enter the injection needle 25 from the injection tube 1 through the connecting sleeve 24. The injection needle 25 is directly connected to the human body. The connecting sleeve 24 is used to contact tissue or blood vessels and is used to inject the medicine in the injection tube 1 into the body. By setting the cooperation of the auxiliary sleeve 101 and the replacement part 2 and other structures, the connecting sleeve 24 is pushed to move in the direction of the injection tube 1. During this process, the connecting sleeve 24 will press the moving block 22, so that the moving block 22 overcomes the elastic force of the limiting spring 23 and moves. The connecting sleeve 24 is rotated to allow the moving block 22 to rotate inside the limiting groove 21. At this time, the old injection needle 25 together with the connecting sleeve 24 can be smoothly removed from the auxiliary sleeve 101, and the new injection needle 25 with the connecting sleeve 24 is inserted into the auxiliary sleeve 101. The moving block 22 will move accordingly in the limiting groove 21 and then rotate again. The connecting sleeve 24 will drive the moving block 22 to continue moving in the limiting groove 21, and then the connecting sleeve 24 will be pulled outward until the moving block 22 and the limiting groove 21 are engaged with each other. At this time, the limiting spring 23 is in a stretched state, thereby further firmly fixing the moving block 22 and the limiting groove 21 to complete the replacement operation of the injection needle 25. When installing a new injection needle 25, by engaging the moving block 22 and the limiting groove 21 with each other and allowing the limiting spring 23 to be in a stretched state, the connecting sleeve 24 of the injection needle 25 can be firmly fixed, which can prevent the injection needle 25 from loosening or falling off due to external force during the injection process.

[0033] like Figures 1 to 3 and Figure 6As shown, the inside of the injection tube 1 is slidably connected with a piston 4, and the piston 4 is made of rubber, one end of the piston 4 is fixedly connected with a push rod 5, and the end of the push rod 5 away from the piston 4 is fixedly connected with a handle, the top of the injection tube 1 close to the replacement part 2 is provided with a groove, and the groove is used for the flow of the drug, and the end of the injection tube 1 close to the replacement part 2 is also installed with a ferrule 6, the top of the ferrule 6 is connected with a storage bin 7, and a top cover 71 is installed on the top of the storage bin 7, and a triangular plate is fixedly connected between the storage bin 7 and the ferrule 6, and The inner wall of the sleeve 6 is connected to the outer wall of the injection tube 1, and one end of the injection tube 1 is connected with the auxiliary sleeve 101, and the limit grooves 21 are symmetrically opened on both sides of the auxiliary sleeve 101. One end of the limiting spring 23 is fixedly connected with a fixing plate 26, and the fixing plate 26 is connected to the inner wall of the connecting sleeve 24. Both sides of the connecting sleeve 24 are provided with accommodating grooves 241, and the accommodating grooves 241 are opened for installing the limiting spring 23, the moving block 22 and the fixing plate 26. The connecting sleeve 24 and the injection needle 25 are connected.

[0034] The above scheme is adopted: the feed tube 31 is located above the quantitative tube 32 and is connected to the inner wall of the top cover 71. It is the channel for the drug to enter the quantitative tube 32 from the storage bin 7. The top blocking block 311 can be controlled to open and close by a knob. It is opened when it is necessary to discharge the drug so that the drug flows into the quantitative tube 32. It is closed at ordinary times to prevent drug leakage. The top half of the quantitative tube 32 has a feed port for receiving the drug from the feed tube 31, and the other half is sealed to prevent drug leakage. The relative position of the quantitative tube 32 and the feed tube 31 can be accurately controlled by sliding the electric slider 35 on the electric slide rail 33 to realize the quantitative discharge function. When the quantitative tube 32 slides to a specific position (the sealing part contacts the feed tube 31), it can also trigger the action of the rotating cover 321 to control the outflow of the drug. The setting of the quantitative tube 32 can accurately control the drug dosage of each injection, improve the accuracy and safety of the injection, and is particularly suitable for treatment scenarios with strict requirements on drug dosage. The electric slide rail 33 and the electric slider 35: the electric slide rail 33 provides a sliding track for the electric slider 35. The electric slider 35 is connected to the bottom surface of the quantitative tube 32. By sliding on the electric slide rail 33, the quantitative tube 32 is driven to move, and docking, separation and other position adjustments with the discharge tube 31 are achieved, thereby completing operations such as quantitative drug delivery and discharge control. The sliding position and speed can be accurately controlled by an external circuit or control system. The baffle 34 is fixedly connected between the two electric slide rails 33, which may protect the internal structure of the electric slide rail 33 and prevent foreign matter such as dust from entering the electric slide rail 33 and affecting its normal operation. At the same time, it may also play a certain supporting and positioning role in the overall structure to ensure the installation stability of the electric slide rail 33 and related components.

[0035] like Figure 2 , Figure 4 and Figure 7As shown, the outer wall of the feed tube 31 is connected to the inner wall of the top cover 71, and a sealing block 311 is clamped on the top of the feed tube 31, and a knob is fixedly connected to the top of the sealing block 311. The bottom surface of the quantitative tube 32 is hinged with a rotating cover 321 through a hinge, and the size of the rotating cover 321 is adapted to the size of the discharge port of the quantitative tube 32. A feed port is provided in half of the top of the quantitative tube 32, and the other half is sealed. The setting of the quantitative tube 32 can prevent the drug inside the feed tube 31 from flowing out during feeding. A feed port is provided in half of the top of the quantitative tube 32, and the other half is sealed. The setting of the quantitative tube 32 can prevent the drug inside the feed tube 31 from flowing out during feeding. The quantitative tube 32 is slidably connected to the electric slide rail 33 through the electric slider 35. When the quantitative tube 32 slides to the sealing part of the quantitative tube 32 through the electric slider 35 and contacts the feed tube 31, the rotating cover 321 can rotate ninety degrees.

[0036] The above scheme is adopted: the piston 4 is made of rubber and slides inside the injection tube 1. Its function is to push the medicine in the injection tube 1 through the connecting sleeve 24 and the injection needle 25 under the push of the push rod 5. The rubber material can ensure the sealing between the piston 4 and the inner wall of the injection tube 1 to prevent drug leakage, and has a certain elasticity to facilitate reciprocating movement in the injection tube 1. One end of the push rod 5 is connected to the piston 4, and the other end is connected to the handle to provide a force point for the user to facilitate pushing the piston 4 for injection operation.

[0037] The working principle and use process of the present invention are as follows: Check whether the components of the device are intact, such as whether the injection tube 1 is damaged, whether the piston 4 can slide normally, whether the injection needle 25 is sharp and not bent, etc. According to the treatment needs, select the injection needle 25 of appropriate specifications. When the injection needle 25 needs to be replaced, push the connecting sleeve 24 to move in the direction of the injection tube 1. During this process, the connecting sleeve 24 will press the moving block 22, so that the moving block 22 overcomes the elastic force of the limiting spring 23 and moves. Then rotate the connecting sleeve 24 to allow the moving block 22 to rotate inside the limiting groove 21. At this time, the old injection can be replaced. The injection needle 25 is smoothly removed from the auxiliary sleeve 101 together with the connecting sleeve 24. Then, a new injection needle 25 with the connecting sleeve 24 is inserted into the auxiliary sleeve 101. The moving block 22 will move accordingly in the limiting groove 21. Then, the connecting sleeve 24 is rotated again. The connecting sleeve 24 will drive the moving block 22 to continue to move in the limiting groove 21. Then, the connecting sleeve 24 is pulled outward until the moving block 22 and the limiting groove 21 are engaged with each other. At this time, the limiting spring 23 is in a stretched state, thereby further firmly fixing the moving block 22 and the limiting groove 21, and completing the replacement operation of the injection needle 25.

[0038] If it is necessary to use the medicine in the storage bin 7 or add auxiliary liquid, open the blocking block 311 on the top of the feeding tube 31 (rotate the knob to open the blocking block 311), control the electric slider 35 to slide on the electric slide rail 33, align the feed port of the quantitative tube 32 with the feeding tube 31, and the medicine in the storage bin 7 flows into the quantitative tube 32 through the feeding tube 31. When the medicine in the quantitative tube 32 reaches the required dose, stop feeding, control the electric slider 35 to slide again, make the sealing part of the quantitative tube 32 contact with the feeding tube 31, and at this time, the feed port on the top of the quantitative tube 32 is closed, and at the same time, the rotating cover 321 at the bottom of the quantitative tube 32 is released from contact with the baffle 34, and the rotating cover 321 rotates, and the medicine in the quantitative tube 32 can flow into the inside of the injection tube 1;

[0039] Insert the injection needle 25 into the injection site of the patient, the user holds the handle and pushes the push rod 5, the piston 4 moves forward in the injection tube 1, and the medicine in the quantitative tube 32 is injected into the patient's body through the connecting sleeve 24 and the injection needle 25. After the injection is completed, the injection needle 25 is pulled out of the patient's body and the discarded injection needle 25 is properly disposed of (put into a dedicated sharps collection container).
