Description

Technical Field

[0001] The present invention relates to medical-related fields, and in particular to a hospital nursing waste compression and storage device and a compression and storage method thereof. Background Art

[0002] Hospital nursing mainly includes three stages. The first is disease-centered care, which is mainly the initial stage of the establishment and development of modern nursing. The second is patient-centered care, which is mainly based on the new health concept and the bio-psycho-social medical model. Nursing has absorbed a large number of theories from related disciplines in its development, such as system theory, human needs hierarchy theory, theory of the relationship between man and environment, etc., which has brought about fundamental changes in nursing. The third is human health-centered care. Due to the rapid development of science and technology and the growing health needs, the spectrum of diseases threatening human health has changed, the trend of medical socialization and mass health has become increasingly obvious, and ensuring health has become a strong driving force for social development, giving the nursing profession a broader vision and practice field, and "nursing centered on human health" has become an inevitable choice.

[0003] In the prior art, there are still certain drawbacks in the process of collecting hospital nursing waste. Nursing waste is usually directly discarded into a storage device. For waste in the form of bottles or boxes, the volume is large during the storage process, and the incremental storage consumes more space. Summary of the invention

[0008] In a further embodiment, a fixed handle is provided above the front end of the storage bucket, a garbage bag positioning hoop is provided on the top of the storage bucket, and one side of the garbage bag positioning hoop is connected to the storage bucket by rotation.

[0009] In a further embodiment, the waste compression processing trough and the release trough are fixedly connected by triangular reinforcement plates, and the number of triangular reinforcement plates is not less than two.

[0010] In a further embodiment, the bottom surface of the waste compression platform is connected to the waste compression processing tank by sliding, and the guide frame is connected to the waste compression platform by welding through a connecting block.

[0011] In a further embodiment, the guide frame is fixedly connected to the electric telescopic rod via a balancing connecting plate, and the electric telescopic rod is fixedly connected to the nursing waste compression and storage body via a mounting foot plate.

[0012] In a further embodiment, the outer end of the automatic opening and closing plate is rotatably connected to the waste compression table by a fixed hinge, the inner end of the automatic opening and closing plate is connected to the waste compression table by inlaying, and the cross-section of the waste compression table is set to an L-shaped structure.

[0013] A method for compressing and storing hospital nursing waste, using the hospital nursing waste compression and storage device, comprises the following steps:

[0014] S1. Discard nursing waste from the disposal port into the waste compression table;

[0015] S2. The waste compression table is driven to slide to one end to the bottom of the compression plate by an electric telescopic rod, and the compression plate is driven downward by a cylinder to compress the nursing waste;

[0016] S3, the waste compression table is driven to slide to the other end by the electric telescopic rod, so that the waste compression table is aligned with the opening, and under the action of gravity, the automatic opening and closing plate is opened downward, so that the compressed waste slides into the slow-release groove, and then falls into the storage barrel in sequence for storage;

[0017] S4. The waste compression table is driven to slide to one end by the electric telescopic rod so that the waste compression table is aligned with the discarding port. At the same time, the automatic opening and closing plate is rotated upward and closed by the fixed hinge. When the storage bin is full, the fixed handle is held and the bin is pulled out effortlessly by the universal self-locking wheels to take out the waste stored inside.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: in the present invention, a compression plate is provided on the top of one side of the interior of the waste compression processing tank, and this structure can compress the nursing waste, so that the storage device has a compression function. Before the nursing waste is stored, it is first compressed to compress the waste into sheets or blocks, which can reduce the amount of storage and save space. More waste can be stored at one time, thereby reducing the storage cost, reducing labor, and being easier to operate. BRIEF DESCRIPTION OF THE DRAWINGS
