Abstract
Description
Technical Field
[0001] This application relates to the field of dispensing devices, and in particular to a dispensing device. Background Technology
[0002] During the medication dispensing process, pharmacists need to dispense the required amount of tablets according to the prescription. When dispensing, the pharmacist first unscrews the bottle cap, then tears off the sealing film at the bottle opening and pours out the tablets. Finally, the pharmacist counts and dispenses the required number of tablets based on the pharmacy's needs.
[0003] In response to the above situation, when there are many pills in the medicine bottle, pharmacists may pour out too many or too few pills, requiring them to frequently count and dispense the pills, which makes dispensing medication inconvenient and increases the pharmacist's workload. Summary of the Invention
[0004] To facilitate medication dispensing by pharmacists, this application provides a dispensing device.
[0005] The dispensing device provided in this application adopts the following technical solution:
[0006] A medicine dispenser includes a medicine dispensing tube, a medicine dispensing plate, and a pressing component;
[0007] The drug dispensing tube is transparent, and a drug dispensing channel is provided through the drug dispensing tube along its length. The inner diameter of the drug dispensing channel is greater than or equal to the diameter of the tablet.
[0008] The drug dispensing plate is provided in a plurality of manner, and the plurality of drug dispensing plates are distributed along the length direction of the drug dispensing tube, and the plurality of drug dispensing plates slide and cooperate with the drug dispensing tube along the axial direction of the drug dispensing tube.
[0009] The dispensing plate has dispensing holes extending through it along its thickness direction, and the inner diameter of the dispensing holes is greater than or equal to the diameter of the tablet.
[0010] The dispensing plate has both a partitioned state and a connected state;
[0011] When the dispensing plate is in the isolated state, the dispensing holes of the dispensing plate and the dispensing pipe are staggered; when the dispensing plate is in the connected state, the dispensing holes of the dispensing plate and the dispensing pipe are connected.
[0012] The pressing component is installed on the drug dispensing tube, and several of the dispensing plates are installed on the pressing component. Pressing the pressing component will switch the dispensing plates between an isolated state and a connected state.
[0013] By adopting the above technical solution, when dispensing medicine, the top of the dispensing tube is inserted into the sealing film of the medicine bottle, and then the end of the pressing member near the top is pressed, so that the dispensing plate at the top enters the communication state, thereby allowing the tablets inside the medicine bottle to pass through the dispensing hole and enter the interior of the dispensing tube.
[0014] After the tablet enters the dispensing tube, the pressure on the top of the pressing device is stopped, and the pressure on the bottom of the pressing device is changed. This causes the dispensing plate at the top to enter a blocking state, while the dispensing plate at the bottom enters a connecting state, allowing the tablet to fall out of the dispensing tube for the pharmacist to dispense.
[0015] When pressing the dispensing device, the number of tablets entering the dispensing tube is observed through the dispensing tube. Combined with the control of the pressing frequency and the amount of pressing, the number of tablets entering or leaving the dispensing tube can be accurately controlled, reducing the occurrence of pharmacists dispensing too many or too few tablets, thus making it easier for pharmacists to dispense the required number of tablets according to the prescription.
[0016] Optionally, the dispensing plates are divided into two groups, and the two groups of dispensing plates are distributed along the length of the dispensing tube, and each group of dispensing plates is provided with several.
[0017] The sliding direction of the dispensing plates in the same group is either facing away from each other or facing each other;
[0018] When the dispensing plates in the same group slide backwards, they will change from a connected state to an isolated state; when the dispensing plates in the same group slide towards each other, they will change from an isolated state to a connected state.
[0019] When all the dispensing plates in the same group are in a separated state, the dispensing holes of the dispensing plates in the same group are staggered; when all the dispensing plates in the same group are in a connected state, the dispensing holes of the dispensing plates in the same group are connected.
[0020] By adopting the above technical solution, the medicine can only pass through the dispensing holes of the dispensing plate when all the dispensing plates in the same group are in a connected state. This allows the movement of the tablets to be controlled by multiple dispensing plates, which helps to ensure the accuracy of control.
[0021] Optionally, the pressing component includes a pressing plate and a return spring. The pressing plate is elastic and is mounted on the drug dispensing tube via the return spring.
[0022] By adopting the above technical solution, it is easy for the pressing component to quickly reset and remain stationary after being stopped being pressed, thereby facilitating the switching between the connected state and the isolated state of the two dispensing plates in the same group.
[0023] Optionally, the drug dispensing cannula is provided with drug dispensing scales, and all drug dispensing scales extend along the length of the drug dispensing cannula.
[0024] By adopting the above technical solution, pharmacists can easily identify the number of tablets by using the dispensing scale, thus making it easier to take out the required number of tablets from the dispensing tube.
[0025] Optionally, the top of the drug dispensing tube is provided with an insertion end, and the insertion end of the drug dispensing tube is set with a pointed angle.
[0026] By adopting the above technical solution, it is easy to insert the dispensing tube into the sealing film of the medicine bottle.
[0027] Optionally, the dispensing plate is movably fitted to the pressing element.
[0028] By adopting the above technical solution, it is easier to press the pressing parts smoothly and reduce the occurrence of pressing parts not being pressed in place.
[0029] Optionally, a connecting rod is provided between the dispensing plate and the pressing component, with both ends of the connecting rod rotatably engaged with the dispensing plate and the pressing component, respectively.
[0030] By adopting the above technical solution, it is easier to press the pressing parts more smoothly, and the occurrence of pressing parts not being pressed in place is further reduced.
[0031] Optionally, the material of the pressing element is a rubber material.
[0032] By adopting the above technical solution, it is easy to reduce the number of parts of the dispensing device, thereby reducing the structural complexity of the dispensing device.
[0033] Optionally, the top of the drug dispensing tube is provided with a drug dispensing groove, which is located on the outer surface of the drug dispensing tube and connected to the drug dispensing pipe, and the width of the drug dispensing groove is greater than or equal to the diameter of the tablet.
[0034] By adopting the above technical solution, the dispensing slot provides more space for the tablets to enter the dispensing tube, which is conducive to the tablets in the medicine bottle entering the inside of the dispensing tube, thus making it easier to enter the dispensing tube with a sufficient number of tablets after the number of tablets in the medicine bottle has decreased.
[0035] Optionally, the outer surface of the drug dispensing tube is provided with a snap-fit groove, which is used to snap the drug dispensing tube into the snap-fit groove.
[0036] By adopting the above technical solution, the drug dispensing tube can be more securely fixed to the sealing film after being inserted into the sealing film through the snap-fit groove.
[0037] In summary, this application includes at least one of the following beneficial technical effects:
[0038] 1. When dispensing medicine, insert the top of the dispensing tube into the sealing film of the medicine bottle, and then press the end of the pressing piece near the top to make the dispensing plate at the top enter the communication state, so that the tablet inside the medicine bottle can pass through the dispensing hole and enter the inside of the dispensing tube.
[0039] After the tablet enters the dispensing tube, the top of the pressing device is stopped, and the bottom of the pressing device is pressed instead. This causes the dispensing plate at the top to enter a blocking state, while the dispensing plate at the bottom enters a connecting state, allowing the tablet to fall out of the dispensing tube for the pharmacist to dispense.
[0040] When pressing the dispensing device, the number of tablets entering the dispensing tube is observed through the dispensing tube. Combined with the control of the pressing frequency and the amount of pressing, the number of tablets entering or leaving the dispensing tube can be accurately controlled, reducing the occurrence of pharmacists dispensing too many or too few tablets, thus making it easier for pharmacists to dispense the required number of tablets according to the prescription.
[0041] 2. It facilitates the rapid reset and static state of the pressing component after it stops being pressed, thereby facilitating the switching between the connected and disconnected states of the two dispensing plates in the same group.
[0042] 3. It makes it easier for pharmacists to identify the number of tablets by using the dispensing scale, thus facilitating the removal of the required number of tablets from the dispensing tube. Attached Figure Description

Detailed Implementation
[0054] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.
[0055] Example 1:
[0056] Embodiment 1 of this application discloses a medicine dispenser. (Refer to...) Figure 1 The dispensing device includes a dispensing tube 1, a dispensing plate 2, and a pressing component.
[0057] Reference Figure 2 The dispensing tube 1 is entirely transparent, and an internal dispensing channel 101 is provided inside the dispensing tube 1. The inner diameter of the dispensing channel 101 is greater than or equal to the diameter of the tablet, so that the tablet located inside the dispensing channel 101 can be observed through the dispensing tube 1. The dispensing channel 101 extends through the length of the dispensing tube 1, allowing the tablet to enter from one end and exit from the other end. In addition, the outer surface of the dispensing tube 1 is provided with dispensing scales 11, which extend along the length of the dispensing tube 1, so that the number of tablets can be determined by the dispensing scales 11.
[0058] In this application, the end of the dispensing tube 1 that is inserted into the medicine bottle is designated as the top, and the end of the dispensing tube 1 that is furthest from the medicine bottle is designated as the bottom. (See reference...) Figure 1 and Figure 2 The top of the dispensing tube 1 is provided with an insertion end 102, which is set at a pointed angle to facilitate the insertion of the dispensing tube 1 into the sealing film of the medicine bottle. In this application, the sealing film can be aluminum foil or a film material that is also laminated with other materials such as paper or plastic film.
[0059] Reference Figure 2 The outer surface of the drug retrieval cannula 1 has four cannula grooves. The four cannula grooves are divided into two groups, and each group has two cannula grooves. The two groups of cannula grooves are distributed along the length of the drug retrieval cannula 1 and are respectively located near the top and bottom of the drug retrieval cannula 1.
[0060] There are four dispensing plates 2, each corresponding to a different insertion cannula groove. Specifically, the four dispensing plates 2 are divided into two groups, with two dispensing plates 2 in each group. The two groups of dispensing plates 2 are distributed along the length of the drug-retrieving insertion cannula 1 and are respectively positioned near the top and bottom of the drug-retrieving insertion cannula 1.
[0061] Four dispensing plates 2 slide along the axis of the dispensing tube 1 via respective insertion grooves, engaging with the dispensing tube 1. The sliding directions of two dispensing plates 2 in the same group are either facing each other or facing away from each other. Specifically, when two dispensing plates 2 in the same group slide towards each other, they move closer together; conversely, when two dispensing plates 2 in the same group slide away from each other, they move further apart.
[0062] The dispensing plate 2 has a dispensing hole 201 extending through it along the thickness direction. The inner diameter of the dispensing hole 201 is greater than or equal to the diameter of the tablet, so that the tablet can move from the top to the bottom of the dispensing tube 1 through the dispensing hole 201.
[0063] All four dispensing plates 2 have both isolated and connected states. When the dispensing plate 2 is in the isolated state, the dispensing holes 201 of the dispensing plate 2 are staggered from the dispensing pipe 101; when the dispensing plate 2 is in the connected state, the dispensing holes 201 of the dispensing plate 2 are connected to the dispensing pipe 101.
[0064] Furthermore, when both dispensing plates 2 in the same group are in a separated state, the dispensing pipe 101 and the two dispensing holes 201 in the same group are staggered, preventing the tablet from moving from the top to the bottom of the dispensing tube 1 through the two dispensing plates 2 in the same group. However, when both dispensing plates 2 in the same group are in a connected state, the dispensing pipe 101 and the two dispensing holes 201 in the same group are interconnected, allowing the tablet to move from the top to the bottom of the dispensing tube 1 through the two dispensing plates 2 in the same group.
[0065] When two dispensing plates 2 in the same group slide in opposite directions, both dispensing plates 2 in the same group will change from a connected state to an isolated state; when two dispensing plates 2 in the same group slide in opposite directions, both dispensing plates 2 in the same group will change from an isolated state to a connected state.
[0066] Therefore, by moving the two dispensing plates 2 at the top of the dispensing tube 1 toward each other, the tablets can enter the interior of the dispensing channel 101, that is, the area of the dispensing channel 101 between the two dispensing plates 2. Then, moving the two dispensing plates 2 at the top of the dispensing tube 1 away from each other will prevent more tablets from entering the interior of the dispensing tube 1. Next, moving the two dispensing plates 2 at the bottom of the dispensing tube 1 toward each other will allow the tablets to fall out of the dispensing channel 101 to the outside of the dispensing tube 1. Finally, moving the two dispensing plates 2 at the bottom of the dispensing tube 1 away from each other will prevent excessive tablets from leaving the interior of the dispensing tube 1, thus facilitating the pharmacist's control over the number of tablets dispensed.
[0067] Reference Figure 1 The device includes two pressing components, located on either side of the dispensing tube 1. Each pressing component comprises a pressing plate 3 and two return springs 4, distributed along the length of the dispensing tube 1. The pressing plate 3 is made of an elastic material such as plastic, and both ends of the pressing plate 3 are fixedly mounted to the dispensing tube 1 via the two return springs 4. Specifically, one end of each return spring 4 is fixedly connected to the dispensing tube 1 via an interference-fit mounting ring, and the other end of each return spring 4 is fixedly connected to the pressing plate 3.
[0068] Reference Figure 1 and Figure 2 The dispensing plates 2 located on the same side of the dispensing tube 1 are rotatably fitted with the pressing plate 3. Two dispensing plates 2, located at the top and bottom of the dispensing tube 1 respectively, are positioned close to the top and bottom of the pressing plate 3, allowing the pressing plate 3 to move each dispensing plate 2. Therefore, by overcoming the elastic force of the return spring 4 and the pressing plate 3, pressing the top or bottom of the two dispensing plates 2 simultaneously will cause the two dispensing plates 2 at the corresponding positions to move towards each other, allowing the tablet to pass through the dispensing hole. When the simultaneous pressing of the top or bottom of the two dispensing plates 2 stops, the return spring 4 and the pressing plate 3 will reset, causing the two dispensing plates 2 at the corresponding positions to move away from each other. Therefore, by pressing different positions of the pressing component, each dispensing plate 2 can be switched between an isolated state and a connected state.
[0069] The implementation principle of a dispensing device in Embodiment 1 of this application is as follows: (Refer to...) Figure 3 When dispensing medicine, insert the insertion end 102 at the top of the dispensing tube 1 into the sealing film of the medicine bottle, and then press the top of the two pressing plates 3 simultaneously, so that the two dispensing plates 2 at the top move towards each other and enter the communication state, thereby allowing the tablets inside the medicine bottle to pass through the dispensing hole 201 and enter the interior of the dispensing tube 101.
[0070] After the tablet enters the dispensing tube 101, the pressing of the top of the two pressing plates 3 is stopped, and the bottom of the two pressing pieces is pressed simultaneously. This causes the two dispensing plates 2 at the top to enter a separated state, and the two dispensing plates 2 at the bottom to enter a connected state, so that the tablet can fall out of the dispensing tube 1 for the pharmacist to dispense.
[0071] When the pressing plate 3 is pressed, the number of tablets entering the dispensing pipe 101 can be observed through the transparent dispensing tube 1. By controlling the pressing frequency and the amount of pressing, the number of tablets entering or leaving the dispensing pipe 101 can be accurately controlled, thereby reducing the occurrence of pharmacists dispensing too many or too few tablets and making it more convenient for pharmacists to dispense the required number of tablets according to the prescription.
[0072] Example 2:
[0073] Embodiment 2 of this application discloses a medicine dispenser, referring to... Figure 4 The main difference from Example 1 is that the number of insertion grooves and dispensing plates 2 are both changed to two, and the number of pressing parts is changed to one.
[0074] When the tablet needs to enter the dispensing tube 101, only the top of the pressing plate 3 needs to be pressed; there is no need for the dispensing holes 201 of the two pressing plates 3 at the top of the dispensing tube 1 to be interconnected. Similarly, when the tablet needs to fall out of the dispensing tube 101 to the outside of the dispensing tube 1, only the bottom of the pressing plate 3 needs to be pressed; there is no need for the dispensing holes 201 of the two pressing plates 3 at the bottom of the dispensing tube 1 to be interconnected, resulting in a simpler structure.
[0075] Example 3:
[0076] Embodiment 3 of this application discloses a connection structure between a dispensing plate and a pressing plate, which can be used to replace the connection method of the dispensing plate 2 and the pressing plate 3 of the dispensing device described in Embodiment 1 or Embodiment 2.
[0077] Reference Figure 5 and Figure 6 A connecting rod 5 is provided between the dispensing plate 2 and the pressing plate 3, and the two ends of the connecting rod 5 are respectively rotatably engaged with the dispensing plate 2 and the pressing plate 3 of the pressing component, so that the dispensing plate 2 is smoother when pressed by the pressing component, and the occurrence of needing to overcome the elasticity of the pressing plate 3 is reduced.
[0078] Example 4:
[0079] Embodiment 4 of this application discloses a medicine dispenser, referring to... Figure 7 The differences from Example 1 include:
[0080] Difference 1: The number of pressing parts is changed to one, and the pressing part is fixedly connected to the drug dispensing tube 1. The pressing part is made of elastic materials such as rubber and silicone.
[0081] Difference 2: The ends of the four dispensing plates 2 furthest from the dispensing tube 1 are all fixedly connected to the pressing component.
[0082] In addition to the differences one and two mentioned above, the medicine dispenser described in Embodiment 4 of this application also includes the following technical features:
[0083] The pressing part has an observation hole 301 extending through it along the thickness direction. The observation hole 301 faces the medicine dispensing scale 11 so as to clearly observe the number of pills in the medicine dispensing channel 101.
[0084] The implementation principle of the dispensing device in Embodiment 4 of this application is as follows: the pressing element relies entirely on its own elasticity to drive the dispensing plate 2 to move along the axial direction of the dispensing tube 1, which makes the structure simpler.
[0085] Example 5:
[0086] Embodiment 5 of this application discloses a drug dispensing cannula, which can be used to replace the drug dispensing cannula 1 of the drug dispenser described in Embodiments 1, 2, or 4. In addition to all the technical features of the drug dispensing cannula 1 of the drug dispenser described in Embodiment 1, the drug dispensing cannula 1 of Embodiment 5 also includes the following technical features:
[0087] Reference Figure 9 The top of the dispensing tube 1 is provided with a dispensing groove 103. The dispensing groove 103 is located on the outer surface of the dispensing tube 1 and is connected to the dispensing pipe 101. The width of the dispensing groove 103 is greater than or equal to the diameter of the tablet, so that the medicine bottle can enter the dispensing pipe 101 through the dispensing groove 103 in addition to entering the dispensing pipe 101 through the insertion end 102 of the dispensing tube 1.
[0088] Additionally, refer to Figure 10 The outer surface of the dispensing tube 1 is provided with a snap-fit groove 104. The snap-fit groove 104 is located at the bottom of the dispensing groove 103 and is used to snap the dispensing tube 1 into the snap-fit groove 104 so that after the dispensing tube 1 is inserted into the sealing film of the medicine bottle, the sealing film snaps into the snap-fit groove 104, thereby making it difficult for the dispensing tube 1 to fall off the medicine bottle.
[0089] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
