Technical Field

[0001] This utility model relates to the field of drug grinding technology, specifically a drug grinding device for critical care. Background Technology

[0002] Critical care refers to the comprehensive monitoring, treatment, and care provided to patients with critical conditions and unstable vital signs. Critical care is typically conducted in the intensive care unit or a specialized intensive care ward. These patients may require ventilator support, circulatory support, nutritional support, and specific treatments for their illness or injury. When administering medication to critically ill patients, some lumpy medications need to be crushed before administration.

[0003] A search revealed a Chinese patent publication number, CN217221812U, which discloses a medication crushing device for intensive care. This patent utilizes a grinding mechanism to facilitate the grinding of medication tablets, reducing the workload of medical staff and improving the efficiency of tablet grinding. The use of a filter hole allows for the removal of larger-diameter granular medications, resulting in a qualified powdered medication that is easier for patients to take. The use of a return spring facilitates the lifting of the medication container, making it easier to remove and dispensing the powdered medication.

[0004] Although the aforementioned patent can filter larger powdered drugs, the aforementioned critical care drug crushing device still has the following problems: the drugs retained after filtration cannot be repeatedly ground, the degree of powdering of the ground tablets is limited, and the grinding quality is limited.

[0005] To address the aforementioned issues, a drug grinding device for critical care is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a drug grinding device for critical care, which solves the problems of limited powdering degree and limited grinding quality in the prior art.

[0013] As a further description of the above technical solution: the drive assembly includes a Z-shaped rod, which is fixedly connected to the right side of the rotating rod, and a rotating sleeve is rotatably connected to the other end of the Z-shaped rod.

[0014] By adopting the above technical solution, the Z-shaped rod is rotated along the rotating shaft by a hand-held rotating sleeve, reducing the force required and increasing the crushing speed.

[0015] As a further description of the above technical solution: the support assembly includes multiple connecting rods, each of which is fixedly connected to the outward side of the connecting plate, and the other end of each connecting rod is fixedly connected to a support plate.

[0016] By adopting the above technical solution, a fixed support plate is connected by a connecting rod to facilitate the support of the grinding device when it is cyclically ground by inverting up and down.

[0017] As a further description of the above technical solution: each of the support plates is provided with a sliding slot at one inward end, and a sliding seat is slidably connected in each sliding slot.

[0018] By adopting the above technical solution, the sliding base slides in the sliding slot to facilitate the sliding base to slide into and block the conical inlet and outlet, thereby preventing the medicine from leaking out during grinding.

[0019] As a further description of the above technical solution: a blower box is fixedly connected to the rear end of the mixing tank, and blower pipes are fixedly connected to both the upper and lower ends of the blower box.

[0020] By adopting the above technical solution, the blower box generates airflow and blows it out through the blower pipe to impact the powder on the pulverizer blade, preventing the powder from remaining on the pulverizer blade.

[0021] As a further description of the above technical solution: the other end of each air blower is located inside the mixing tank.

[0022] By adopting the above technical solution, the powder can be easily cleaned from the pulverizing blades by penetrating the mixing chamber through the air pipe.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. The present invention provides a drug grinding device for critical care. Firstly, the grinding device can be used for cyclic grinding by inverting the device through the support components provided at both the top and bottom.
