Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tablet grinding and drug delivery device. Background Art

[0002] Drugs come in many forms, the most common ones are tablets, capsules, granules and pills. Pharmaceutical companies generally determine the drug's form based on its ingredients, effects and applicable population.

[0003] Some patients in the hospital who temporarily lose their ability to swallow independently, or who eat with the help of a nasogastric tube, cannot swallow tablets or capsules directly. The outer coating of capsule drugs can be removed, and the granules or powder in the capsule can be dissolved in water before feeding. For tablets and drugs with larger particles, the routine operation is to put them in a bowl and soak them in water, or place the tablets in a mortar and crush them, then mix them with water and feed them.

[0004] However, the operation method of soaking tablets and large-particle drugs is easy to be confused with other patients' medicine soaking containers, and there is a risk of taking the wrong medicine. The mortar pounding method requires the container to be cleaned every time to avoid cross-contamination between drugs. It cannot be used by one person for one purpose, and there is a greater risk of drug contamination. Therefore, a tablet grinding and dosing device is proposed. Utility Model Content

[0007] Preferably, the grinding dispenser comprises a grinding cylinder movably connected to the three-way valve, and a grinding push rod is movably connected in the grinding cylinder.

[0008] Preferably, the grinding cylinder includes an integrally formed loading section, an internal thread section, and a pagoda head, the pagoda head is movably connected to the three-way valve, the grinding push rod includes an integrally formed push rod body, a push plate, an external thread section, and a grinding head, the grinding head is movably connected to the inner wall of the loading section, the internal thread section is threadedly connected to the external thread section, a grinding ridge is provided on one side of the loading section close to the pagoda head, and the grinding head is movably connected to the grinding ridge.

[0009] Preferably, the loading section is a transparent plastic sleeve, and scale lines are provided on its surface.

[0010] Preferably, a support plate is provided on a surface of the internal thread section close to the grinding push rod.

[0011] Preferably, the push plate is in a petal shape.

[0012] Preferably, a sealing ring is provided at the connection between the grinding head and the inner wall of the loading section.

[0013] Preferably, a valve core is provided in the middle of the three-way valve, the top of the valve core is located outside the three-way valve, and an integrally formed on mark and a closed mark are provided on the top of the valve core.

[0014] Preferably, a liquid-stop clamp is fixedly installed in the middle of the hose.

[0015] The working principle of the tablet grinding and drug delivery device of the utility model is as follows: a three-way valve connects a syringe, a hose and a grinding and drug delivery device, a valve core is arranged on the three-way valve to change the conduction condition of the structure connected on the three-way valve, tablets or large-particle drugs are placed in the loading section, the grinding push rod is rotated, and the grinding head is rotated and pushed forward, so that the drugs are rubbed and ground on the grinding ridges, so that the tablets or large-particle drugs are ground into powder, the three-way valve is used to connect the syringe and the grinding cylinder, and the outlet on one side of the hose is closed, and the solution in the syringe is pushed into the grinding cylinder to mix with the drug powder, the three-way valve then connects the grinding cylinder and the hose, and the outlet on one side of the syringe is closed, and the drug solution in the grinding cylinder is pushed into the hose to complete the drug delivery, the push plate is in the shape of a petal, which can play a good anti-slip role, and the force of the grinding and drug delivery operations is better, and the liquid stop clamp on the hose can squeeze the hose to block the drug delivery and prevent the drug from leaking when the device is not connected to the patient.

[0016] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0017] 1. The medicine is ground by the provided grinding and dosing device. The three-way valve connects the syringe, the grinding and dosing device and the hose. By changing the conduction structure of the three-way valve, the medicine grinding, dissolving and delivery can be achieved. The dosing device can be better used by one person to prevent the medicines of different patients from being contaminated with each other, which is beneficial to improving the practicality of the device.

[0018] 2. By connecting the external thread section on the grinding push rod with the internal thread section on the grinding cylinder, when the grinding push rod is rotated, the grinding push rod will move into the grinding cylinder, thereby extruding and grinding the medicine. Compared with directly pushing the grinding push rod, the grinding effect is better, further improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
