Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a medicine crushing device for critical care. Background Art

[0002] Clinically, care for critically ill patients is extremely important. Most critically ill patients have difficulty swallowing, coma, etc. When patients need to take medicine, taking medicine in the form of tablets may cause the tablets to get stuck in the throat or respiratory tract, causing a dangerous situation of suffocation. In addition, the physical condition of critically ill patients may affect the absorption and metabolism of the medicine, thereby affecting the treatment effect. Therefore, when critically ill patients need to take medicine, the medicine needs to be crushed and taken in the form of powder by mouth, nasogastric feeding, enema, etc.

[0003] When using the medicine crushing device in the prior art, the tablets are usually placed in a grinding jar, and then the medicine is ground with a handheld grinding pestle. After the grinding, the medicine powder is poured out. During the grinding process, a small amount of medicine will remain on the grinding jar and the grinding pestle, resulting in insufficient dosage of medicine taken by the patient, affecting the patient's medication effect. Therefore, in response to the above problems, we propose a critical care medicine crushing device. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a critical care medicine crushing device. After the medicine is ground, the grinding surface of the medicine crushing device can be directly scraped clean to avoid medicine residues that affect the dosage of the medicine taken by the patient.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a critical care medicine crushing device, comprising a grinding cylinder and a grinding pestle located inside the grinding cylinder, the upper end of the grinding pestle is connected to a rotating rod, one end of the rotating rod extends to the outside of the grinding cylinder and is rotatably connected to the top of the grinding cylinder, a scraper is provided inside the grinding cylinder, the outer wall of the scraper is in contact with the inner wall of the grinding cylinder, the scraper is located above the grinding pestle, the scraper comprises a scraper ring, a brush provided on the inner wall of the scraper ring and a shovel ring connected to the bottom of the scraper ring, the scraper ring, the shovel ring, the grinding pestle and the grinding cylinder have the same central axis, a connecting piece is provided at the upper end of the scraper ring, one end of the connecting piece extends to the outside of the grinding cylinder and is slidably connected to the top of the grinding cylinder, and a spring is connected between the upper end of the connecting piece and the outer wall of the top of the grinding cylinder.

[0006] The beneficial effects of the utility model are as follows: the grinding pestle is driven to rotate in the grinding cylinder by the rotating rod to grind the medicine; after the medicine is ground into powder, the scraping member is moved downward by pressing the connecting rod multiple times to scrape the inner wall of the grinding cylinder clean; then the rotating rod is rotated to make the brush brush the medicine powder on the surface of the grinding pestle off, thereby avoiding the medicine residue on the grinding surface and affecting the dosage of the medicine taken by the patient.

[0007] In order to increase the friction between the grinding pestle and the tablet;

[0008] As a further improvement of the above technical solution: a plurality of grinding grooves are arranged on the upper end of the grinding pestle, and the plurality of grinding grooves are arranged equidistantly along the central axis of the grinding pestle.

[0009] The beneficial effect of this improvement is that by setting the grinding grooves on the upper end of the grinding pestle, the tablets can be better initially ground when entering the grinding cylinder and starting to be ground, thereby improving the grinding effect and speed. Then, the remaining drug residue after grinding falls into the gap between the grinding pestle and the inner wall of the grinding cylinder, and the smooth grinding between the two makes the drug powder ground more finely.

[0010] In order to facilitate the downward movement of the scraper, the shovel ring can enter the gap between the grinding pestle and the inner wall of the grinding cylinder;

[0011] As a further improvement of the above technical solution: the maximum thickness of the shovel ring is smaller than the minimum gap between the grinding pestle and the inner wall of the grinding cylinder.

[0012] The beneficial effect of this improvement is that after the tablets are ground, the grinding piece moves downward, and the shovel ring enters the gap between the grinding pestle and the inner wall of the grinding cylinder, shoveling off the powder on the inner wall of the grinding cylinder and the grinding pestle, thereby reducing the residual powder.

[0013] In order to completely scrape off the powder on the inner wall of the grinding cylinder;

[0014] As a further improvement of the above technical solution: the inner height of the scraper is greater than the height of the grinding pestle.

[0015] The beneficial effect of this improvement is that when the scraper moves downward, the grinding pestle is wrapped inside the scraper, and the bottom of the shovel ring is flush with the bottom of the grinding cylinder, so that the powder on the inner wall of the grinding cylinder can be completely scraped off.

[0016] In order to facilitate the placement of tablets between the inner wall of the grinding cylinder and the grinding pestle for grinding;

[0017] As a further improvement of the above technical solution: a drug inlet is provided on the outer wall of the grinding cylinder, a drug inlet channel is opened on the grinding cylinder, the drug inlet is connected to the grinding cylinder through the drug inlet channel, and the drug inlet channel is located below the scraper.

[0018] The beneficial effect of this improvement is that the tablets are placed in the medicine inlet and enter the grinding cylinder through the medicine inlet channel. At this time, since the medicine inlet channel is below the scraper, the tablets will not be blocked by the scraper and can enter the grinding cylinder smoothly for grinding.

[0019] In order to collect the powder in time;

[0020] As a further improvement of the above technical solution: the bottom of the grinding cylinder is threadedly connected with a collecting cup for collecting medicine powder.

[0021] The beneficial effect of this improvement is that the ground medicine powder will fall into the collection cup from the gap between the inner wall of the grinding cylinder and the grinding pestle, and then the collection cup can be rotated away from the grinding cylinder to provide the patient with the medicine powder.

[0022] In order to increase the friction between the grinding cylinder and the hand;

[0023] As a further improvement of the above technical solution: an anti-skid sleeve is provided on the outer wall of the grinding cylinder, and a plurality of anti-skid lines are provided on the anti-skid sleeve.

[0024] The beneficial effect of this improvement is that the provision of the anti-slip sleeve can increase the friction between the grinding cylinder and the hand when grinding the tablets, thereby increasing the tablet grinding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
