Abstract
Description
Technical Field
[0001] This utility model relates to the field of syringe technology, and more specifically, to a double-tube syringe booster. Background Technology
[0002] A syringe is a common medical device consisting of a syringe barrel with a small hole at the tip and a matching plunger. Syringes are used to inject or extract small amounts of liquid or gas into areas inaccessible by other methods. Liquid or gas is drawn in through the small hole at the tip of the syringe when the plunger is withdrawn, and expelled when the plunger is pushed back in. This process of drawing or injecting gas or liquid using a syringe and needle is called injection.
[0003] During their work, the inventors discovered the following problems with existing syringes: 1. When preparing medications in a hospital, it is usually necessary to use multiple syringes to inject different medications into the same container in sequence, which is time-consuming and may affect the preparation effect; 2. To prevent venous catheter blockage, flushing and sealing procedures are usually required. This requires medical staff to perform the procedures in steps, that is, to use one syringe to draw up flushing fluid and inject it into the catheter, and then use another syringe to inject sealing fluid into the catheter, which is relatively inefficient.
[0004] In view of this, the inventors invented a dual-tube syringe booster to solve the above problems. Utility Model Content
[0005] To address the problems existing in the prior art, a dual-tube syringe booster is provided.
[0006] The purpose and effect of this utility model are achieved by the following specific technical means: it includes a mounting block, a sleeve, and a syringe. Two sleeves are provided and fixed on both sides of the mounting block respectively. Two syringes are provided and embedded in the two sleeves respectively. It also includes a driving component for pushing the syringe, a booster and a T-shaped pressure plate of the driving component. The booster is mounted on the mounting block. The T-shaped pressure plate is rotatably connected to the end of the booster. Each syringe has a push rod that is sealed and slidably connected inside. The inner side of the T-shaped pressure plate has three limiting grooves that match the push rod.
[0007] The mounting block has a mounting hole at its upper end; The booster includes an electric push rod or an elastic telescopic component. The lower end of the electric push rod or elastic telescopic component is fixed in the mounting hole, and the upper end extends out of the mounting hole and is rotatably connected to the T-shaped pressure plate.
[0008] The elastic telescopic component includes a first sleeve, an inner rod, and a spring. The first sleeve is fixed in the mounting hole, the inner rod is slidably connected to the first sleeve, and the spring is sleeved on the outside of the inner rod, with the upper and lower ends of the spring contacting the T-shaped pressure plate and the first sleeve, respectively.
[0009] The mounting block is fitted with a battery, control panel, and switch via slots. The electric push rod, switch, and battery are connected in series, and the control panel and switch are electrically connected.
[0010] A pressure sensor is installed at the inner end of the push rod through a slot. The pressure sensor has a built-in button battery and is connected to the control panel for signal transmission.
[0011] The mounting block has through holes on its side and the inside of the two sleeves. The three through holes are interconnected. A limiting member for limiting the two syringes is installed in the middle through hole. The middle part of the limiting member protrudes from the surface of the mounting block.
[0012] The limiting component includes a second sleeve, a screw, and two threaded sleeves. The second sleeve is rotatably connected to the middle through hole and protrudes from the surface of the mounting block. The screw is fixed inside the second sleeve, and the two threaded sleeves are threaded onto both ends of the screw, and both threaded sleeves are slidably connected to the inner wall of the middle through hole.
[0013] The syringe has a needle installed at its lower end, and a tubing fitted around the needle is also attached to the lower end of the syringe. The tubing is curved.
[0014] The beneficial effects of this utility model are: The use of a booster and a T-plate enables this dual-barrel syringe booster to have a dual-mode injection system, as detailed below: Synchronous mode: Two syringes can be advanced or injected at the same speed, which is suitable for the simultaneous extraction of incompatible drugs, as well as flushing fluid and sealing fluid. Alternating mode: By rotating the T-shaped pressure plate, the T-tail of the T-shaped pressure plate is aligned with one of the push rods, which moves the push rod first. Then, the T-tail of the T-shaped pressure plate is aligned with the other push rod, which moves the push rod, thus achieving step-by-step injection. This mode is suitable for flushing and sealing intravenous catheters.
[0015] Both of these modes can greatly improve work efficiency. Attached Figure Description

Detailed Implementation
[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-7 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.
[0020] like Figure 1 and 5As shown, a dual-tube syringe booster includes a mounting block 1, a sleeve 2, and a syringe 3. Two sleeves 2 are provided and fixed to both sides of the mounting block 1. Two syringes 3 are provided and embedded in the two sleeves 2 respectively. The sleeves 2 are made of transparent plastic. The mounting block 1 and the sleeves 2 can be connected by bolts, snap-fit connections, or integral molding. The device also includes a driving component for pushing the syringe 3, a booster 4, and a T-shaped pressure plate 5. The booster 4 is mounted on the mounting block 1, and the T-shaped pressure plate 5 is rotatably connected to the end of the booster 4. The booster 4 facilitates the stable movement of the T-shaped pressure plate 5. The T-head of the T-shaped pressure plate 5 can be aligned with two syringes 3, and the T-tail can be aligned with a single syringe 3. This design meets the needs of simultaneous injection by two syringes 3 or sequential injection by two syringes 3.
[0021] like Figure 2 and 6 As shown, the mounting block 1 has a mounting hole 12 at its upper end; the booster 4 includes an electric push rod 41 or an elastic telescopic component 42. The lower end of the electric push rod 41 or the elastic telescopic component 42 is fixed in the mounting hole 12, and the upper end extends out of the mounting hole 12 and is rotatably connected to the T-shaped pressure plate 5. The electric push rod 41 drives the T-shaped pressure plate 5 to move through electricity, so that the T-shaped pressure plate 5 automatically pushes the syringe 3, which saves time and effort and can be precisely controlled; the elastic telescopic component 42 and the T-shaped pressure plate 5 are used together and require manual operation to push the syringe 3. The operation is simple and the cost is low. It can be selected according to the needs.
[0022] Furthermore, a battery 13, a control panel 7, and a switch 8 are installed on the mounting block 1 through a slot. The electric push rod 41, the switch 8, and the battery 13 are connected in series. The control panel 7 is electrically connected to the switch 8. The battery 13 provides power to the control panel 7 and the electric push rod 41. The control panel 7 can control the opening and closing of the switch 8, or manually open and close the switch 8 to control the opening and closing of the electric push rod 41. The working time of the electric push rod 41 can be preset through the control panel 7 to achieve precise control of the injection volume of the syringe 3 by pressing.
[0023] like Figure 6-7 As shown, the elastic telescopic component 42 includes a first sleeve 421, an inner rod 422, and a spring 423. The first sleeve 421 is fixed inside the mounting hole 12. The inner rod 422 is slidably connected to the first sleeve 421. The spring 423 is sleeved on the outside of the inner rod 422, and the upper and lower ends of the spring 423 are in contact with the T-shaped pressure plate 5 and the first sleeve 421, respectively. The spring 423 always exerts a spring force on the inner rod 422 so that the T-shaped pressure plate 5 can return to its original position after the syringe 3 has finished injecting.
[0024] like Figure 2As shown, a push rod 31 is slidably connected inside the syringe 3. A pressure sensor 311 is installed at the inner end of the push rod 31 through a slot. The pressure sensor 311 has a built-in button battery and is connected to the control panel 7. The pressure sensor 311 is used to test the hydraulic pressure inside the syringe 3 and below the push rod 31. The control panel 7 can preset the hydraulic pressure value of the pressure sensor 311 so that the control panel 7 can accurately control the working time of the electric push rod 41. A needle 32 is installed at the lower end of the syringe 3. A conduit 9 is fitted around the needle 32 at the lower end of the syringe 3. The conduit 9 is curved.
[0025] Furthermore, the inner side of the T-shaped pressure plate 5 has three limiting grooves 51 that match the push rod 31. The setting of the limiting grooves 51 facilitates the limiting of the top of the push rod 31, which is beneficial for the drive component to stably push the push rod 31.
[0026] like Figure 2 and 3 As shown, through holes 11 are opened on the side of the mounting block 1 and the inner sides of the two sleeves 2. The three through holes 11 are interconnected. A limiting member 6 for limiting the two syringes 3 is installed in the middle through hole 11. The middle part of the limiting member 6 protrudes from the surface of the mounting block 1. The limiting member 6 includes a second sleeve 61, a screw 62 and two threaded sleeves 63. The second sleeve 61 is rotatably connected in the middle through hole 11 and protrudes from the surface of the mounting block 1. The screw 62 is fixed in the second sleeve 61. The two threaded sleeves 63 are respectively threaded onto the two ends of the screw 62, and the threaded sleeves 63 are slidably connected to the inner wall of the middle through hole 11.
[0027] Working principle: like Figure 1-3 As shown, in order to ensure that the syringe 3 is stably located in the sleeve 2, the medical staff can rotate the second sleeve 61. The second sleeve 61 will drive the screw 62 to rotate in the middle through hole 11. At the same time, the screw 62 will push the two threaded sleeves 63 to move towards the two syringes 3 respectively. When the second sleeve 61 is difficult to rotate, it means that the two threaded sleeves 63 have limited the two syringes 3 respectively.
[0028] The booster 4 uses an electric push rod 41, such as Figure 1 and 2As shown, in the initial state, the tops of the two push rods 31 are embedded in the two limiting grooves 51 of the T-head of the T-shaped pressure plate 5. During use, medical personnel can first click on the control panel 7 to preset the working time of the electric push rod 41, i.e., preset the dosage of medicine drawn by the syringe 3. Then, insert the two needles 32 into the two medicine bottles respectively. Next, hold the T-shaped pressure plate 5 with one hand while simultaneously holding the two push rods 31 with two fingers. With the other hand, activate the electric push rod 41 by clicking on the control panel 7, and immediately grasp the mounting block 1 to prevent it from moving upwards. The electric push rod 41 will push the T-shaped pressure plate 5 upwards, simultaneously... Move the two push rods 31 upwards. During this process, the needle 32 will draw the medicine from the medicine bottle into the syringe 3 until the electric push rod 41 reaches its working time. Then, turn off the electric push rod 41 by switching off the control panel 7 with the switch 8. During the medicine drawing process, the electric push rod 41 operates in a start-stop state. Of course, during the above operation, medical staff can also manually turn on and off the switch 8 to start the electric push rod 41 or turn off the power of the electric push rod 41. This allows medical staff to use it according to the actual situation, so as to draw out equal amounts of two different medicines at the same time, saving time and accurately drawing out the dosage. After that, the needle 32 is pulled out from the medicine bottle. If you want to draw two different doses of medication at the same time, medical staff can preset two working periods, which are not continuous. That is, during the medication drawing process, the electric push rod 41 operates in the state of start-stop-start-stop, which makes it easy for medical staff to know that one medication has been drawn. Medical staff do not need to hold the corresponding push rod 31 anymore. Then the other medication will be drawn until it is drawn. Then the needle 32 is pulled out of the medication bottle, which can achieve the goal of drawing two different doses of medication at the same time. This can also achieve the goal of saving time and accurately drawing the medication. Next, the medication is prepared. The two needles 32 are aligned with a container, and the electric plunger 41 is activated again. This time, the electric plunger 41 moves the T-shaped pressure plate 5 downwards. During this process, the T-shaped pressure plate 5 pushes the two plungers 31 to move within the two syringes 3 respectively, allowing the two syringes 3 to quickly inject two different medications into the same container. This shortens the medication preparation time and ensures better efficacy. If the container opening is small, medical personnel can also place a curved catheter 9 over the outside of the needle 32 (e.g., Figure 2 As shown), the liquid ejected from the needle 32 is drained so that the injected liquid enters a container with a smaller opening.
[0029] When flushing and sealing an intravenous catheter, the flushing and sealing fluids can be aspirated simultaneously. The aspiration process will not be detailed here. Flushing and sealing must be performed separately. Figure 2 and 4As shown, the electric push rod 41 drives the T-shaped pressure plate 5 to continue moving upward, so that the T-shaped pressure plate 5 has enough space to rotate. When the T-head of the T-shaped pressure plate 5 is misaligned with the two push rods 31 and the T-tail of the T-shaped pressure plate 5 is aligned with the syringe 3 containing flushing fluid, the rotation stops. The electric push rod 41 continues to drive the T-shaped pressure plate 5 downward, and the T-shaped pressure plate 5 pushes the push rod 31 in the syringe 3 to move, performing a flushing operation on the intravenous catheter. After flushing, the electric push rod 41 drives the T-shaped pressure plate 5 upward. When the T-shaped pressure plate 5 moves above the syringe 3 containing sealing fluid, the T-shaped pressure plate 5 is rotated so that the T-tail of the T-shaped pressure plate 5 is aligned with the syringe 3 containing sealing fluid. Then, the electric push rod 41 continues to drive the T-shaped pressure plate 5 downward, driving the push rod 31 in the syringe 3 to perform a sealing operation on the intravenous catheter. Compared with the current method of performing flushing and sealing operations on intravenous catheters, the efficiency is improved by 40%.
[0030] Booster 4 uses a flexible telescopic component 42, such as Figure 5-7 As shown, the synchronous extraction and injection of drugs and the flushing and sealing of intravenous catheters are basically similar, and will not be described in detail here. The main description here is the working state of the elastic telescopic component 42 when in use. When medical staff manually press down the T-shaped pressure plate 5, the T-shaped pressure plate 5 will push the inner rod 422 downward and compress the spring 423 at the same time. It should be noted that the elastic telescopic component 42 has enough telescopic length for the push rod 31 to be used normally. After the syringe 3 finishes injecting, medical staff only need to release the T-shaped pressure plate 5. The compressed spring 423 will release its elastic potential energy and push the T-shaped pressure plate 5 upward. There is no need to manually push the T-shaped pressure plate 5, which is more convenient.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
