Detailed Description

As shown in fig. 1-4, the present invention includes a grinder; the grinder comprises a grinder outer tube 3 and a grinder push rod 9; the outer tube 3 of the grinder is in the shape of a syringe hollow tube, and a push rod 9 of the grinder is in a syringe push rod structure matched with the syringe hollow tube; the method is characterized in that:

a grinding cavity 4 is further arranged at the front end of the inner cavity of the outer tube 3 of the grinder, and a grinding head 7 is arranged in the grinding cavity 4; the front end part of the injector push rod-shaped structure is detachably connected with the grinding head 7;

when in use, the tablet is placed in the grinding cavity 4, and the injector push rod-shaped structure moves back and forth or rotates along the outer tube 3 of the grinder to drive the grinding head 7 to grind or grind the tablet into powder in the grinding cavity 4.

Preferably, the grinding head 7 is a dome-shaped structure, an inner wall of the dome-shaped structure is provided with an internal thread, an end of a push rod of the syringe push rod-shaped structure is provided with an external thread, and the dome-shaped structure and the syringe push rod-shaped structure are connected through a thread.

Preferably, the grinding chamber 4 is a shell with one open side, and a long rod is arranged in the inner cavity of the shell and extends out of the inner cavity; the end part of the long rod is provided with a spherical bulge, and the radius of the spherical bulge is larger than that of the long rod; a gap is formed between the grinding cavity 4 and the inner wall of the outer tube 3 of the grinder; a cavity with an open end is arranged at the end part of the grinder push rod 9, and a through hole is arranged at the center of the round cap-shaped structure of the grinding head 7; when in use, the long rod sequentially passes through the grinding head 7 and the grinder push rod 9 which are connected by threads until the long rod reaches the chamber of the grinder push rod 9, and the spherical bulge is left in the chamber of the push rod 9; the radius of the spherical bulge is larger than the width of a cavity of a push rod of the grinder; (the injection molding material has micro elasticity, so the spherical protrusion can enter the chamber and is not easy to fall off.) when the injector rod-pushing structure is pulled outwards from the grinder outer tube 3, the grinding cavity 4 is driven to move in the grinder outer tube 3.

Preferably, an O-ring 6 is disposed inside the grinding head 7 and sleeved on the long rod for preventing the solution or the medicine powder from entering the through hole of the grinding head 7 when the long rod of the grinding chamber drives the grinding head 7 to move. So that the interior of the push rod 9 chamber of the grinder is kept in a pollution-free state, and the grinder can be repeatedly used. In particular, the long rod of the grinding cavity can be prevented from entering gaps when being matched with the sealing rubber ring. The interior of the push rod cavity of the grinder is kept in a pollution-free state, and the effectiveness of the grinder which can be used repeatedly is improved.

Preferably, a buffer rubber sleeve 5 is further arranged between the grinder push rod 9 and the grinding head 7, and is used for filling the space between the grinding head 7 and the grinder push rod 9. The buffer rubber sleeve is made of rubber.

Preferably, a sealing rubber sleeve 8 for sealing is arranged between the grinder push rod 9 and the grinder outer tube 3.

Preferably, the dome-like structure of the grinding bit 7 is provided with protruding tips that facilitate grinding.

Preferably, grooves for assisting in flow guiding are arranged on the outer wall of the grinding cavity 4, the outer wall of the grinding head 7, the buffer rubber sleeve 5 and the sealing rubber sleeve 8. The device can make the solution enter and exit the grinder more smoothly in the processes of water absorption and injection.

Preferably, the outer wall of the grinder outer tube 3 is provided with scales, a specified amount of solution can be inhaled according to the scales to dissolve the medicine, the head of the grinder outer tube is the same as the size of a common injection needle tube, and the grinder outer tube can be matched with a syringe needle tube to perform work such as intravenous injection.

Preferably, the inner wall of grinding chamber 4 is provided with strip arch, and the pressure when can increasing the medicine and grind makes the process of grinding more laborsaving, and after smashing the medicine, rotatory mill push rod can further process into littleer granule rank with the medicine, and the grinding chamber afterbody is provided with the stock, can slide certain distance in the cavity of mill push rod. The groove arranged on the outer side can accelerate the flow of the solution when the solution is sucked and injected. And a strip-shaped bulge is arranged outside the grinding head 7 and is matched with the grinding cavity for grinding.

Specifically, the O-shaped ring 6, the buffer rubber sleeve 5 and the sealing rubber sleeve 8 are all of a butyl rubber structure, so that the device is highly corrosion-resistant, flexible and airtight, and the service life of the device is longer. The outer tube of the grinder is made of medical PP materials and has good rigidity and impact resistance.

The outer tube wall 3 of the grinder, the grinding chamber 4, the grinding head 7, the push rod 9 of the grinder are all formed by processing through an injection molding process, wherein the grinding chamber 4 and the grinding head 7 are 5.5mm in thickness and have the punching capability of grinding medicines, the scales on the outer tube wall of the grinder 3 are measured according to the actual absorbed water amount of the grinder, and after the outer tube wall is marked with a position, scale marks are printed by laser, the outer diameter of the outer tube wall 3 of the grinder is close to that of a medical common 60M L syringe, in the process of sucking and discharging the solution by the grinder, the solution cannot be discharged partially due to the fact that no gap exists between the grinding chamber 4 and the outer tube 3 of the grinder, and therefore 4 grooves are processed on the outer side of the grinding chamber 4.

In particular, the grinder may grind the drug powder and may be fused with a solution for injection into another vessel or patient's mouth. The working process comprises the following steps: firstly, pulling out a grinder push rod 9, placing medicines into a grinding cavity 4, placing one or more medicines at a time, then pushing the grinder push rod 9 inwards, when pushing to the bottom of an outer tube 3 of the grinder, starting to bear the force of the grinding cavity 4 and a grinding head 7, and then forcibly grinding the medicines into powder and accumulating the powder into the grinding cavity 4; insert the mill again in the solution that needs dissolve, pull mill push rod 9 to the outside, inhale the medicine to grinding chamber 4 in, according to the scale of mill outer tube 3 wall, inhale appropriate solution volume, rock mill 4, make the medicine fully dissolve. Pushing the grinder push rod 9 pushes the solution into another vessel or directly into the patient's mouth.

It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
