Description

A medicine grinding syringe

Technical Field

The present application relates to the technical field of medical devices, and in particular to a drug-grinding syringe.

Background Art

In modern medicine, patients often lose the ability to take care of themselves, especially those who temporarily lose the ability to swallow after surgery. They need the help of a nutrition tube to deliver nutrients to the stomach, and they also need drug-assisted treatment. However, some oral medications are too large to pass directly through the nutrition tube. At this time, a grinder is needed to grind the tablets into small pieces and then input them into the nutrition tube.

For example, the utility model patent with publication number CN208435980U specifically discloses a grinding syringe. When grinding, the medicine is put into the medicine inlet, and the piston rod is pushed forward until the first grinding block and the second grinding block contact each other. Then, the piston rod is rotated to grind the tablet into powder. This closed grinding method reduces the waste caused by splashing of medicine during grinding.

In the above-mentioned patent disclosure, the device sets two sets of grinding blocks inside the syringe, so that the tablets can be quickly ground by rotating the piston rod. However, this grinding method still requires manual grinding by nurses. When the patient's demand is large, the powder may not be ground in time, which may delay the patient's injection. Therefore, it is necessary to provide a syringe with a fast grinding function to solve the above problem.

It should be noted that the above information disclosed in this background technology section is only for understanding the background technology conceived of the present application, and therefore, it may contain information that does not constitute the prior art.

DETAILED DESCRIPTION

It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

As shown in Figure 1, the present application provides a drug grinding syringe, including a console 1, on which a drug grinding mechanism 2 is fixedly installed, and the drug grinding mechanism 2 includes a rotating device 3 and a syringe 4, wherein the syringe 4 is used to grind drug powder, and the rotating device 3 is suitable for driving the syringe 4 to rotate under the control of the console 1, so that the tablets in the syringe 4 are fully ground and then injected into the patient's body.

As shown in Figures 2 and 3, the syringe 4 includes an outer sleeve 41, which is set through and has an injection port 412 at one end. A triangular groove 411 is set at the top of the inner side of the outer sleeve 41, and a push rod 42 is slidably installed in the outer sleeve 41. The top of the push rod 42 is provided with a boss 421 that matches the groove 411. When it is necessary to grind tablets, the tablets are first placed in the outer sleeve 41, and then the push rod 42 is pushed into the outer sleeve 41 so that the tablets are between the groove 411 and the boss 421. At this time, the tablets can be ground into powder by rotating the push rod 42, which solves the problem of powder residue in traditional grinding equipment and ensures that all the powder is used for patients.

At the same time, a protective cap 43 is installed at one end of the outer sleeve 41 away from the push rod 42. The protective cap 43 is used to protect the syringe 4 from being contaminated and damaged. The inner side of the protective cap 43 is provided with a thread. At the same time, a rotating block adapted to the thread is provided at the outer end of the injection port 412. Through the cooperation of the thread and the rotating block, the protective cap 43 is fixedly installed on the outer side of the injection port 412.

The inner side of the protective cap 43 is recessed inward and is provided with an inner cone 431, which is matched with the size of the injection port 412. When the protective cap 43 is installed on the outer side of the injection port 412, the inner cone 431 is snapped into the injection port 412 to seal it, and an exhaust groove 432 is designed on the inner cone 431. When grinding medicine, the syringe 4 does not need to unscrew the protective cap 43, but only needs to directly pull out the push rod 42 and put the medicine into the outer sleeve 41 for grinding. At this time, the air in the outer sleeve 41 will be discharged through the exhaust groove 432.

As shown in FIG4 , the rotating device 3 includes a fixing frame 31, a bearing on one side of the fixing frame 31 is connected to a rotating shaft 32, one end of the rotating shaft 32 is provided with a mounting groove 321, the mounting groove 321 is adapted to the size of the push rod 42, and a clamping block 322 is provided on the top bolt of the mounting groove 321. When the push rod 42 is inserted into the mounting groove 321, the clamping block 322 is rotated to make it contact with the push rod 42, so that the push rod 42 is fixed in the mounting groove 321;

Meanwhile, a fixing groove 323 is provided on the other side of the fixing frame 31. The fixing groove 323 is provided through, and the through portion is adapted to the size of the outer jacket 41. The fixing groove 323 is used to fix the outer jacket 41 on the fixing frame 31.

At the same time, a transmission part 5 is arranged on one side of the rotating shaft 32. The transmission part 5 in this embodiment can be a rotating motor or a rotating handle. The transmission part 5 drives the push rod 42 to rotate, so that the tablets between the groove 411 and the boss 421 are ground, reducing the burden of manual crushing.

A container 6 is provided on one side of the fixing frame 31 on the console 1. The container 6 is used to hold water. A PVC pipe 7 is installed in the container 6. A liquid stop switch 71 is provided on the PVC pipe 7. When the powder is ground and water needs to be added to mix it into liquid medicine, one end of the PVC pipe 7 is inserted into the water and the other end is connected to the injection port 412. At this time, the syringe 4 automatically draws water to mix the powder and water.

In summary, the device is equipped with a transmission part 5 that can quickly rotate the push rod 42, so that the tablets in the syringe 4 can be ground into powder conveniently and easily, reducing the burden on the staff and increasing the practicality of the device.

The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
