Description

Disposable medicine feeder

Technical Field

The invention relates to the technical field of an extruder, in particular to an extruder of a disposable drug delivery device.

Background

Hemorrhoid, also called hemorrhoid, is the most common anal disease in clinical practice, often speaking, "nine hemorrhoids in ten men" and ten hemorrhoids in ten women ", which is seen in the wide range of patients with hemorrhoids. Hemorrhoids are well documented in traditional chinese medicine. The recent concept of hemorrhoids was proposed by Thomson in 1975: hemorrhoids are pathologically enlarged pads at the lower end of the rectum. Hemorrhoids can be classified into internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids, depending on the location of the affected part. Internal hemorrhoids are currently believed to be pathological changes or displacements in the supporting structure of the anal pad (anal canal vascular pad), vascular plexus and arteriovenous anastomotic support. The well-developed parts of the internal hemorrhoid are 3, 7 and 11 points of the lithotomy. The main manifestations are bleeding and prolapse. A common clinical symptom of internal hemorrhoids is bleeding after intermittent defecation. Some patients may have difficulty defecation. Pain occurs when internal hemorrhoids are complicated by thrombosis, incarceration, and infection. External hemorrhoids are pathological dilations or thromboses of the subcutaneous vascular plexus distal to the dentate line. The mixed hemorrhoid is a mixture of internal hemorrhoid and external hemorrhoid. However, in the process of hemorrhoid conservative treatment, the affected part needs to be coated with the medicine, which is very inconvenient, and meanwhile, the attachment effect of the coated medicine is poor, which further influences the treatment of the patient.

Compared with the prior art, the invention has the following beneficial effects:

1. the medicine storage bottle like toothpaste or the bellows type medicine storage bottle is connected below the threaded connector, the extruding head is inserted into the anus, and the medicine storage bottle is extruded, so that the medicine in the medicine storage bottle enters the rectum of a human body through the extruding head, and the use of a patient is facilitated.

2. The inclined angle of forty-five to ninety degrees between the annular baffle and the extrusion head of the invention accords with the physiological structure of human body, is beneficial to the attachment of medicine, ensures the use safety, simultaneously, the diameters of the middle ends of nine to thirteen inner cavities are medicine extrusion holes between one and two millimeters, and are uniformly distributed from ninety degrees to one hundred twenty degrees in the same plane, so that the medicine can be uniformly extruded and distributed to be attached to the affected part, and simultaneously, the capability of preventing the extruded medicine from flowing back can be achieved under the influence that the diameter of the outer end of the inner cavity of the medicine extrusion hole is larger than the diameter of the inner end of the inner cavity of the medicine extrusion hole.

3. The fool-proof hole is in a fool-proof design, so that a user can conveniently and correctly recognize the insertion direction of the squeezer, and meanwhile, the threaded joint of M10X 1.25 can be in standard connection with other medicine storages, so that the fool-proof hole is convenient to popularize.
