Description

Technical Field

[0001] This utility model specifically relates to an ampoule opening device, belonging to the field of medical device technology. Background Technology

[0002] Ampoules are a type of heat-sealing hard glass container commonly used to store injectable drugs, vaccines, serums, etc. They are widely used in the modern medical field. To open an ampoule, the mouth needs to be broken off from the neck to separate the body from the mouth. Manual opening is often used, but it is not only slow but also prone to causing scratches. Some ampoule openers are now available on the market.

[0003] For example, Chinese Patent CN223280611U describes an ampoule opener, which includes a first cylinder, a second cylinder, and a cutting mechanism. The first and second cylinders are respectively provided with a first central hole and a second central hole. The first and second cylinders are coaxially arranged, and the lower end of the first cylinder is connected to the upper end of the second cylinder by a hinge. The lower end of the first cylinder has an installation groove, and the cutting mechanism is set in the installation groove. The cutting mechanism is equipped with a grinding wheel. The cutting mechanism is connected to the first cylinder by an adjustment mechanism. The overall structure is simple, easy to operate, and can be used for ampoules of different sizes, which reduces the risk of manual opening to a certain extent.

[0004] However, when using it, one needs to hold the ampoule body with one hand and the bottle opener with the other to apply force and break the bottle neck from the neck point. However, the break point is close to the hand holding the bottle body, so there is still a risk of scratching. In addition, when breaking it, one needs to open it one by one and apply a lot of force, which is labor-intensive. Moreover, when used in hospital intravenous preparation centers, a large number of ampoules need to be opened, and the opening efficiency is low when operating one by one. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an ampoule opening device that prevents hand injuries, reduces the workload of medical staff, and improves the efficiency of opening ampoules.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a bottle opening device for ampoules, comprising a frame and a support mechanism for placing ampoules. In use, a support mechanism matching the type of ampoule to be opened is selected, and the ampoules are inserted one by one into their designated positions on the support mechanism. The support mechanism is slidably engaged with the frame. A T-shaped slide rail is provided in the middle of the frame, and a gear is rotatably mounted inside the slide rail, meshing with the support mechanism. When the gear rotates, the support mechanism carries the ampoules along the slide rail. A swing arm is rotatably mounted on one side of the upper end of the frame, and a second electric telescopic rod is hinged to the upper end of the frame. The telescopic end of the second electric telescopic rod is hinged to the upper end of the swing arm. When opening the bottle, the second electric telescopic rod extends, and the swing arm swings down to an inclined state. A pushing structure is embedded inside the frame on one side of the swing arm, and the telescopic end of the pushing structure is connected to the swing arm. When opening the ampoule, because the swing arm is tilted, when the extension end of the push structure pushes the bottle mouth, the bottle mouth tilts towards the swing arm, causing the bottle mouth to break off at the neck point. The broken bottle mouth is then clamped between the extension end of the push structure and the swing arm. A cutting blade, which is either a grinding wheel or a diamond cutter, is threaded onto one side of the frame near the push structure. As the ampoule passes the blade of the cutting blade, the blade... The neck of the ampoule is cut with a slit to make it easier to break the bottle at the slit when the bottle opening is bent. During use, a collection box for waste collection can be placed on one side of the frame. After the bottle opening is broken off, the second electric telescopic rod retracts, the swing arm rotates along the upper end of the frame, and the telescopic end of the push structure continues to extend. When the bottle opening is above the collection box, the telescopic end of the push structure retracts, and the bottle opening falls into the collection box for automatic collection.

[0007] Furthermore, the lower end of the frame is fixedly equipped with a clamping component for clamping onto one side of the external workbench, which facilitates the overall fixation and improves stability during use. In addition, a notch is opened at the lower internal end of the frame, and the lower end of the bearing mechanism is engaged with the notch, which facilitates the limiting and guiding of the lower end of the bearing mechanism and improves the stability of the bearing mechanism moving on the frame.

[0008] Furthermore, a servo motor is fixedly installed at the lower end of the middle position of the frame. The output end of the servo motor is connected to the shaft end of the gear through a gearbox. When the servo motor is started, the gearbox causes the gear to rotate, which in turn moves the bearing mechanism on the slide.

[0009] Furthermore, the pushing structure includes a first electric telescopic rod, and a push plate is hinged to the end of the first electric telescopic rod. An elastic element is fixedly installed at both the upper and lower ends of one side of the push plate. The elastic element is either an elastic band or a spring. The other end of the elastic element is fixedly connected to the hinged position of the first electric telescopic rod and the push plate. A pressure sensor is installed at the position where the push plate connects to the first electric telescopic rod to detect the pushing force applied to the ampoule opening. Through the hinge, when the first electric telescopic rod extends, one side of the push plate better fits the ampoule opening, improving the uniformity of the applied force. And through the elastic element, the push plate automatically returns to a vertical state when contracted.

[0010] Furthermore, the supporting mechanism includes a frame, the upper end of which has a placement position with an internal rubber ring. When the ampoule is inserted into the placement position, the stability of the ampoule is improved due to the action of the internal rubber ring. After the ampoule is inserted, it forms a shape similar to a spring chain, which is convenient for opening one by one. A sensing point is installed on one side of the lower end of the frame, directly below the placement position, so that the frame can sense the position of the ampoule.

[0011] Furthermore, a sensor is embedded in one side of the lower end of the frame, and the sensor corresponds to the sensing point. The sensor is either a laser sensor or a through-beam sensor, used to sense the position of the ampoule. A control board is fixedly installed on one side of the upper end of the frame. The frame has a built-in circuit board and a battery. The control board is electrically connected to the circuit board to facilitate overall control.

[0012] Furthermore, a slide bar with teeth inside is fixedly installed on one side of the frame. The slide bar is slidably engaged inside the slide rail, and the gear meshes with the teeth inside the slide bar. The slide bar is engaged in the slide rail to prevent it from disengaging, and the teeth facilitate the gear to drive the frame, so that the frame can move carrying the ampoule.

[0013] Furthermore, a lifting plate is slidably installed inside the frame, with both ends of the lifting plate extending to the outside of the frame. After the bottle is opened and the liquid medicine inside is extracted, the lifting plate facilitates pushing the bottle out of the placement position for the next use.

[0014] Furthermore, hand handles are fixedly installed at both ends of the frame and at both ends of the lifting plate to facilitate the lifting of the lifting plate and push the bottle out.

[0015] Beneficial effects: By employing a carrier mechanism that holds multiple ampoules and allowing each ampoule to pass between a swing arm and a push structure to break off its cap, the ampoules can be opened automatically, reducing the workload of medical staff. Furthermore, the opening process requires no manual intervention, offering high protection against scratches. After the cap is broken off, waste material automatically falls off for easy collection, improving the efficiency of opening ampoules. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6As shown, an ampoule opening device includes a frame 3 and a support mechanism 1 for placing the ampoule. The support mechanism 1 is slidably engaged with the frame 3. A T-shaped slide rail 7 is provided in the middle of the frame 3. A gear 10 is rotatably installed inside the slide rail 7 and meshes with the support mechanism 1. A swing arm 5201 is rotatably installed on one side of the upper end of the frame 3. A second electric telescopic rod 5202 is hinged to the upper end of the frame 3. The telescopic end of the second electric telescopic rod 5202 is hinged to the upper end of the swing arm 5201. The second electric telescopic rod 5202 and the swing arm 5201 form a breaking structure 52. A pushing structure 51 is embedded inside the frame 3 on one side of the swing arm 5201. The pushing structure 51 and the breaking structure 52 form a... A breaking component 5, which breaks off the bottle necks in pairs, pushes the telescopic end of the structure 51 and the swing arm 5201 to open the ampoules. A cutting component 4, including a cutting blade 401, is threadedly connected to one side of the push structure 51 on the frame 3. The frame 3, the cutting component 4, and the breaking component 5 together form the bottle opening mechanism 2, used to break off the ampoule necks. In use, a waste collection box can be placed on one side of the frame 3 first. The frame 3 is then fixed to the edge of the external operating table by the clamp 6. A carrier mechanism 1 that matches the size of the ampoule to be opened is selected, and the ampoules are inserted one by one into the carrier mechanism 1, forming a chain-like shape. Then, the carrier mechanism 1 is inserted into the slide 7, and the carrier mechanism is opened by the rotation of the gear 10. 1. Moving along slide 7, as the ampoule moves, it passes the cutting blade 401. The blade of the cutting blade 401 scratches the neck (neck point) of the ampoule, meaning the blade of the cutting blade 401 can contact the neck point of the ampoule in placement position 102 and form a cut at the neck point. Then, the ampoule moves between the swing arm 5201 and the pushing structure 51. The telescopic end of the pushing structure 51 extends. Since the swing arm 5201 is in an inclined state, when the pushing mechanism extends, the pushing mechanism applies force to the bottle mouth, causing the bottle mouth to tilt and break off the bottle mouth from the neck point, separating the bottle mouth from the bottle body. After breaking off, the second electric telescopic rod 5202 retracts, the swing arm 5201 rotates at the upper end of the frame 3, and the telescopic end of the pushing structure 51 extends. The end continues to push, moving the broken bottle neck to the top of the collection box. Then, the retracting end of the pushing structure 51 retracts, and the bottle neck falls into the collection box for automatic collection. After the bottle neck falls, the swing arm 5201 and the pushing structure 51 reset, and the carrying mechanism 1 moves to open the next ampoule. After opening, the medicine inside the opened ampoule is extracted for use by holding the carrying mechanism 1. In the whole process, the ampoule only needs to be in contact with the carrying mechanism 1 when it is installed on the carrying mechanism 1 and when the carrying mechanism 1 is taken out to extract the medicine from the ampoule after it is opened. The opening process does not require manual contact by medical staff, which greatly reduces the risk of hand cuts. Moreover, the automatic opening and collection of the bottle neck also improves the opening efficiency, making it suitable for use in the inoculation center.

[0020] As a technical optimization of this utility model, a clamping component 6 for clamping onto one side of an external workbench is fixedly installed at the lower end of the frame 3. The clamping component 6 uses a screw, a clamping plate, and a nut in cooperation. The screw is fixedly installed on one side of the bottom of the frame 3, the clamping plate is sleeved on the screw, and the nut is screwed onto the screw. The upper side of the nut is pressed tightly against the clamping plate. When fixed, the bottom of the frame 3 and the clamping plate are clamped to the edge of the external table or workbench. The bottom of the frame 3 and the upper surface of the clamping plate are treated with anti-slip material to improve the stability after the whole is fixed. The lower end of the internal part of the frame 3... A notch 11 is provided, and the lower end of the supporting mechanism 1 is engaged with the notch 11. A servo motor 9 is fixedly installed at the lower end of the middle position of the frame 3. The output end of the servo motor 9 is connected to the shaft end of the gear 10 through the gearbox. In use, the servo motor 9 drives the gear 10 to rotate through the gearbox. The gear 10 pushes the supporting mechanism 1, thereby causing the supporting mechanism 1 to slide inside the slide 7, which drives the ampoule to move. When moving, the notch 11 limits the bottom of the supporting mechanism 1, and the slide 7 limits one side of the supporting mechanism 1, improving the stability when the bottle mouth is broken.

[0021] As a technical optimization of this utility model, the pushing structure 51 includes a first electric telescopic rod 5102, and a push plate 5101 is hinged to the end of the first electric telescopic rod 5102. When hinged, it is connected by a hinge member, and a pressure sensor is installed between the hinge member and the push plate 5101 to sense the pressure applied by the push plate 5101 to the ampoule. One side of the push plate 5101 is made of a rubber pad material that is bonded together. Elastic members 5103 are fixedly installed at the upper and lower ends of one side of the push plate 5101. The elastic element 5103 is either an elastic band or a spring. The other end of the elastic element 5103 is fixedly connected to the hinge position of the first electric telescopic rod 5102 and the push plate 5101. When the mouth of the ampoule is broken off, the swing arm 5201 is in an inclined state, while the first electric telescopic rod 5102 extends, causing the push plate 5101 to apply force to the mouth of the ampoule, breaking off the mouth at the neck point. After resetting, the push plate 5101 returns to a vertical state due to the pulling of the elastic element 5103.

[0022] As a technical optimization of this utility model, the supporting mechanism 1 includes a frame 101. The upper end of the frame 101 has a placement position 102 with a built-in rubber ring. That is, the placement position 102 is a circular hole structure with an embedded rubber ring. When placing an ampoule, the ampoule body is inserted into the placement position 102, and the built-in rubber ring improves the stability of the ampoule after insertion. Multiple sensing points 104 are installed on one side of the lower end of the frame 101, directly below the placement position 102, and are arranged along the length of the frame 101. A sensor 8 is embedded on one side of the lower end of the frame 3. Located at the lower end of the slide rail 7 on the frame 3, and with an embedded installation, sensor 8 corresponds to sensing point 104. When sensor 8 detects sensing point 104, servo motor 9 stops, indicating that the ampoule is between swing arm 5201 and push plate 5101, improving the accuracy of opening the ampoule. Control board 12 is fixedly installed on the upper end of the frame 3 on the inclined surface. The frame 3 has a built-in circuit board and battery. Sensor 104 is electrically connected to servo motor 9 through the built-in circuit board of the frame 3. Control board 12 is electrically connected to the built-in circuit board and battery of the frame 3, improving the automation effect during use. One side of the frame 101... A sliding bar 105 with internal teeth is provided in the direction of the slide. The sliding bar 105 is slidably engaged inside the slide rail 7, and the gear 10 meshes with the teeth on the sliding bar 105. Thus, the sliding bar 105 engages one side of the frame 101 inside the slide rail 7 to prevent disengagement. The teeth also facilitate the movement of the frame 101 inside the slide rail 7 when the gear 10 rotates. For ampoule displacement, a lifting plate 103 is slidably installed inside the frame 101. A rubber pad is fixedly installed on the upper surface of the lifting plate 103 directly below the placement position 102 to provide a cushioning effect. Both ends of the lifting plate 103 extend to the outside of the frame 101. Hand-held ears 106 are fixedly installed at both ends of the frame 101 and at both ends of the lifting plate 103 for holding with both hands. After the liquid in the ampoule is drawn out by the syringe, the hand-held ears 106 on the frame 101 and the lifting plate 103 are pinched by the thumbs and forefingers of both hands respectively, so that the lifting plate 103 moves towards the placement position 102, which makes it easier to push out the ampoule body in the placement position 102. That is, when the lifting plate 103 rises, the ampoule located in the placement position 102 is pushed out for medical waste disposal. There is no need to manually touch the ampoule, which is convenient to operate and prevents scratches. In addition, a handle is fixedly installed on one side of the frame 3 for easy handling of the whole.
