Description

Technical Field

[0001] The utility model belongs to the technical field of veterinary drug delivery devices, in particular to a portable solvent-type drug quantitative delivery device. Background Art

[0002] The veterinary drug dispenser is a tool specifically used to feed solvent-based drugs to animals. It is widely used and important. It can help veterinarians or breeders to feed solvent-based drugs to animals accurately and quickly, thereby effectively preventing and treating animal diseases. The veterinary drug dispenser not only improves the efficiency and accuracy of solvent-based drug feeding, but also reduces the risk of solvent-based drug waste and cross-infection.

[0003] When administering medication to rats or mice, the sharp teeth of the rats or mice may damage the guide hose, which requires frequent replacement of the hose or direct replacement of the entire medication dispenser. At the same time, due to the large number of rats or mice involved in the experiment, medication using existing medication dispensers becomes quite cumbersome. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a portable solvent-type drug quantitative dosing device, which has the advantages of being able to automatically administer drugs to rats or mice and preventing the guide tube from being bitten, thereby solving the problems existing in the prior art.

[0005] The utility model is implemented as follows: a portable solvent-type drug quantitative dosing device comprises a quantitative component and a catheter component, wherein the quantitative component is connected to the catheter component;

[0006] Wherein, a first accommodating chamber is provided in the quantitative component, a second accommodating chamber is provided in the catheter component, and the first accommodating chamber and the second accommodating chamber are communicated with each other;

[0007] The material of the catheter component is a hard material.

[0008] As a preferred embodiment of the present invention, the catheter assembly includes a hard tube body and a ball;

[0009] The lumen in the hard tube body is a second accommodating cavity, the openings formed at both ends of the hard tube body are a connecting opening and a flow opening, respectively, and the hard tube body at the connecting opening is connected to the quantitative component;

[0010] The ball is installed in the second accommodating cavity, the ball is located at the flow opening, and the ball is used to cover the flow opening.

[0011] As a preferred embodiment of the present invention, the quantitative assembly includes a syringe, which is located at the upper end of the hard tube body and is threadedly connected to the hard tube body;

[0012] Wherein, the lumen in the syringe is the first accommodating cavity.

[0013] As a preferred embodiment of the present invention, the quantitative component also includes a first airbag, which is located at the upper end of the syringe and fixedly connected to the syringe, and an air outlet of the first airbag is connected to the first accommodating cavity.

[0014] As a preferred embodiment of the present invention, the first airbag is cylindrical, and the upper side and the lower side of the first airbag are both made of hard materials.

[0015] As a preferred embodiment of the present invention, a fixing plate is installed on the upper end of the first airbag, and a driving plate is installed on the outer surface of the first airbag;

[0016] A plurality of springs are installed between the driving plate and the fixing plate.

[0017] As a preferred embodiment of the utility model, a positioning plate is fixedly connected to the outer surface of the syringe, and two symmetrical hook rods are installed on one side of the positioning plate.

[0018] As a preferred embodiment of the present invention, the hook rod is arc-shaped.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] When preparing solvent-based drugs for rats or mice, since they cannot operate the drug delivery device by themselves, we first need to have a professional insert the catheter partially into the container containing the drug. Then, by operating the dosing device, the suction it generates is used to extract the drug from the container. The drug is stored in two different areas in the catheter, namely the second receiving chamber and (in the case of excess) the first receiving chamber. After the extraction is completed, the professional removes or separates the catheter from the container.

[0021] When giving medicine to rats or mice, since they are usually kept in cages, we can hang the drug dispenser inside the cage. By utilizing the natural licking behavior of rats or mice, the catheter and the quantitative device work together to generate negative pressure in the second containing chamber, thereby prompting the rats or mice to absorb the medicine by themselves. This method not only simplifies the complexity of manual operation, but also improves the accuracy and efficiency of drug administration. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0030] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0031] See also Figures 1 to 6 A portable solvent-type drug dosing device provided by an embodiment of the utility model includes a dosing component and a catheter component, wherein the dosing component is connected to the catheter component; wherein a first accommodating chamber 1 is provided in the dosing component, and a second accommodating chamber 2 is provided in the catheter component, and the first accommodating chamber 1 and the second accommodating chamber 2 are communicated with each other; and the material of the catheter component is a hard material.

[0032] The above scheme is adopted: when in use, first, since rats or mice themselves cannot operate the drug dispenser, before feeding the solvent-based drug, the staff can insert the catheter assembly into the medicine tank or medicine bottle with the solvent-based drug solution in advance, and then the staff can operate the quantitative assembly to use the negative pressure generated by the quantitative assembly to draw the solvent-based drug in the medicine tank or medicine bottle. After the solvent-based drug is drawn, the solvent-based drug is at least contained in the second accommodating chamber 2 located in the catheter assembly. In the case where too much solvent-based drug is drawn, part of the solvent-based drug will be contained in the second accommodating chamber 2, and the other part will be contained in the first accommodating chamber 1. After the solvent-based drug is drawn, the staff can take the catheter assembly out of the medicine tank or medicine bottle or separate the catheter assembly from the medicine tank or medicine bottle.

[0033] When it is necessary to feed solvent-based drugs to rats or mice, since rats or mice are usually placed in cages, the staff can hang the drug dispenser in the cage, and use the natural licking behavior of rats or mice to generate negative pressure in the second accommodating chamber 2 through the interaction between the catheter assembly and the quantitative assembly, so that the solvent-based drugs are absorbed by the rats or mice themselves. This process not only reduces the cumbersome steps of manual operation, but also improves the accuracy and efficiency of drug administration. In addition, since the catheter assembly is made of hard materials, it effectively prevents rats or mice from biting the catheter during the licking process, ensuring the stability and continuity of the drug administration process.

[0034] Furthermore, the catheter assembly includes a hard tube body 3 and a ball 4; wherein the tube cavity inside the hard tube body 3 is a second accommodating cavity 2, and the openings formed at both ends of the hard tube body 3 are respectively a connecting port and a flow port, and the hard tube body 3 at the connecting port is connected to the quantitative assembly; the ball 4 is installed in the second accommodating cavity 2, and the ball 4 is located at the flow port, and the ball 4 is used to cover the flow port.

[0035] The above scheme is adopted: during use, when it is necessary to feed solvent-based drugs to rats or mice, the drug dispenser has been fixed in the cage and can enable the rats or mice to touch the position of the hard tube body 3, and then the natural licking behavior of the rats or mice is utilized. Since part of the ball 4 is in the second accommodating chamber 2 and the other part is exposed, when the rats or mice lick the ball 4, the ball 4 is driven and moves along the direction from the flow port to the connecting port, so that a gap is generated between the surface of the ball 4 and the flow port, and then the solvent-based drug in the second accommodating chamber 2 flows out from the gap or the solvent-based drug adheres to the surface of the ball 4 exposed at the flow port, so that the solvent-based drug can be licked by the tongue of the rats or mice.

[0036] It should be noted that the lower end of the hard tube body 3 is inclined, thereby restricting the ball 4 .

[0037] Furthermore, the quantitative component includes a syringe 5, which is located at the upper end of the hard tube body 3 and is threadedly connected to the hard tube body 3; wherein the tube cavity in the syringe 5 is the first accommodating cavity 1.

[0038] Furthermore, the quantitative component also includes a first airbag 6 , which is located at the upper end of the syringe 5 and fixedly connected to the syringe 5 , and an air outlet of the first airbag 6 is connected to the first accommodating chamber 1 .

[0039] Furthermore, the first airbag 6 is cylindrical, and the upper side and the lower side of the first airbag 6 are both made of hard materials.

[0040] Furthermore, a fixing plate 7 is installed at the upper end of the first airbag 6 , and a driving plate 8 is installed on the outer surface of the first airbag 6 ; a plurality of springs 9 are installed between the driving plate 8 and the fixing plate 7 .

[0041] The above scheme is adopted: when in use, when it is necessary to draw the solvent-type medicine in the medicine tank or medicine bottle, at this time, the staff can press the driving plate 8 to compress the first airbag 6, so that the first airbag 6 gradually changes from the expanded state to the compressed state, so that the gas in the first airbag 6 is pushed into the second accommodating chamber 2, and then the hard tube body 3 can be placed in the medicine tank or medicine bottle. After the hard tube body 3 enters the medicine bottle or medicine tank, the driving plate 8 is released, and the spring 9 resets the driving plate 8 and drives the first airbag 6 to expand again, and the gas is extracted from the first accommodating chamber 1 or the second accommodating chamber 2, so as to form a negative pressure in the first accommodating chamber 1 or the second accommodating chamber 2. This negative pressure acts on the solvent-type medicine in the medicine tank or medicine bottle through the circulation port, and sucks it into the second accommodating chamber 2. At the same time, the ball 4 automatically adjusts its position according to the flow of the solvent-type medicine, allowing the solvent-type medicine to pass through. If the solvent-type medicine is no longer drawn, the ball 4 falls and continues to cover the circulation port.

[0042] When rats or mice naturally lick the ball 4, as the solvent-based drug in the second accommodating chamber 2 decreases, negative pressure will gradually be generated in the first accommodating chamber 1 or the second accommodating chamber 2. Since the first air bag 6 is connected to the first accommodating chamber 1, this negative pressure effect will be transmitted to the first air bag 6, causing its volume to decrease or deform. The generation of negative pressure will also promote the dissolution and mixing of the solvent-based drug in the first accommodating chamber 1 or the second accommodating chamber 2, further improving the utilization efficiency of the solvent-based drug.

[0043] It should be noted that: first, when the first accommodating chamber 1 generates negative pressure, the first airbag 6 will also be deformed. At this time, an external hose can be connected to the tank body with a cleaning liquid. When the first airbag 6 gradually changes from a deformed state to an initial state, the cleaning liquid can be transmitted to the first airbag 6 through the hose. When there is no solvent-based medicine in the first accommodating chamber 1 and the second accommodating chamber 2, the first airbag 6 can be compressed again to allow the cleaning liquid to enter the first accommodating chamber 1 and the second accommodating chamber 2 through the air outlet, thereby cleaning the first accommodating chamber 1 and the second accommodating chamber 2. Second, a one-way valve can be installed at the connection between the first accommodating chamber 1 and the air outlet of the first airbag 6 to control the outflow of the cleaning liquid or gas. Third, a sliding block is also slidably installed on the outer surface of the syringe 5, and a plurality of support rods are installed between the sliding block and the drive plate 8 to support the drive plate 8.

[0044] Furthermore, a positioning plate 10 is fixedly connected to the outer surface of the needle cylinder 5 , and two symmetrical hook rods 11 are installed on one side of the positioning plate 10 .

[0045] Furthermore, the hook rod 11 is arc-shaped.

[0046] Adopting the above scheme: when in use, the staff only needs to hang one end of the hook rod 11 on the cage, and then let the hook end slide naturally into the cage structure until it is fully inserted and remains stable, so as to easily complete the fixation of the drug dispenser, ensure the smooth progress of the drug administration process, and prevent the safety hazard caused by the accidental falling of the drug dispenser, thereby improving the overall safety.

[0047] When the dispenser needs to be moved, the staff can hold the hook rod 11 with their hands and move the dispenser, which not only improves the portability of the dispenser, but also enables the staff to quickly and easily carry the dispenser to the designated location when needed, thereby improving work efficiency and flexibility.

[0048] The working principle of this utility model:

[0049] First, since experimental animals (such as rats or mice) cannot operate the drug delivery device by themselves, when preparing solvent-based drugs, the staff needs to connect the catheter assembly to the medicine can or bottle containing the solvent-based drugs in advance. Then, by operating the quantitative assembly, the drug is extracted from the medicine can or bottle using the negative pressure generated. In this process, the solvent-based drug is first stored in the second accommodating chamber 2 of the catheter assembly. If the amount of drug exceeds this capacity, the excess will enter the first accommodating chamber 1. After completing the drug extraction, the staff can disconnect or remove the catheter assembly from the medicine can or bottle.

[0050] Next, when it is necessary to administer medication to the experimental animals, since they are usually placed in cages, the staff can hang the medication dispenser in the cages. By utilizing the natural licking behavior of the experimental animals, the synergistic effect of the catheter assembly and the quantitative assembly forms a negative pressure in the second accommodating chamber 2, so that the solvent-based medication is inhaled into the body by the experimental animals. This method simplifies the medication process and improves the accuracy and efficiency of medication.

[0051] In addition, the catheter assembly is designed with hard materials, which effectively prevents experimental animals from damaging the catheter during licking, ensuring the stability and continuity of the drug administration process.
