Description

A drug grinding syringe

technical field

The utility model relates to the field of medical equipment, in particular to a drug grinding syringe.

Background technique

Patients are often unable to take medicine by themselves due to the influence of disease.

detailed description

The utility model will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the utility model and are not intended to limit the scope of the utility model.

As shown in Figure 1, a drug grinding syringe is mainly composed of a syringe 1 and a grinding part 2 arranged on the outer wall of the syringe and communicated with the inner cavity 11 of the syringe. As shown in Figure 2, the grinding part 2 includes a grinding chamber 21, a grinding rod 22 and a grinding Cover 23, the grinding cover 23 is arranged on the grinding chamber 21, and is adapted to the mouth of the grinding chamber 21, the center of the grinding cover 23 is provided with a through hole 24 adapted to the grinding rod 22, and the grinding rod 22 passes through the through hole 24 into the grinding chamber 21. In clinical operation, first open the grinding cover 23, put the medicine to be ground into the grinding chamber 21, then close the grinding cover 23, and then use the grinding rod 22 to grind the medicine. After the grinding is completed, put the syringe After the piston 12 is pulled to the grinding part 2, the ground drug enters the inner cavity 11 of the syringe, and enters the gastric tube through the injection port 13 of the syringe under the action of the piston 12. In this embodiment, the grinding cover 23 and the grinding chamber 21 are connected by threads, but those skilled in the art can also use other conventional connection methods, such as buckle connection and the like.

In order to be able to grind the medicine and to facilitate the control of the ground medicine entering the inner cavity 11 of the syringe, the medicine grinding syringe also includes a movable partition 25 arranged at the bottom of the grinding chamber 21, and the partition 25 is arranged at the bottom of the grinding chamber 21. And the position of the side wall of the grinding chamber 21 corresponding to the spacer 25 is provided with a hole matching the spacer, and the sliding end of the spacer 25 is provided with a pull rod 26. The spacer 25 can slide out of the grinding chamber 21 under the action of the pull rod 26, Before the grinding of the drug is completed, the septum 25 is closed (see Figure 1) to separate the grinding part 2 from the inner cavity of the syringe. The tab 25 is removed (see FIG. 3 ) so that the ground drug can enter the syringe lumen 11 .

In addition, in order to improve the grinding efficiency of the medicine and make the tablet grind more finely, as shown in Figure 4, another preferred solution of the medicine grinding syringe is: it also includes a motor 3 and a grinding blade 32, and the grinding blade 32 is arranged in the grinding chamber 21 , and driven by the motor 3, the operation button 31 of the motor 3 is arranged on the grinding part 2, after the tablet is put into the grinding cavity 21, the grinding cover 23 is closed, then the operation button 31 of the motor 3 is pressed, and the grinding blade 32 Driven by the motor, the tablet is rotated and ground in the grinding chamber 21 .

Due to the different sizes of the ground drug particles, in order to prevent larger particles from entering the gastric tube and blocking the gastric tube, a filter 27 is provided at the connection between the side wall of the syringe 1 and the grinding part 2 .

In this embodiment, a rubber gasket is provided in the through hole 24 of the grinding cover 23 to prevent the medicine in the grinding chamber from spilling out during the grinding process.

The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
