Description

A rotary push type sausage enema

technical field

The utility model relates to a hand-held sausage enema, in particular to a rotary-push sausage enema.

Background technique

The enema method is to use a catheter from the anus through the rectum to insert liquid into the colon to achieve the effects of laxative exhaust, cooling, ql induced labor, dilution of intestinal toxins, reduction of absorption, health care, etc. In addition, it can also achieve the effects of supplying drugs, nutrition, Moisture and other therapeutic purposes. Enema can be divided into cleaning enema, retention enema, etc. Enema is also called enema bag and bowel cleanser. The name approved by the State Food and Drug Administration is called defecation and bowel cleanser. The drip-type enema bag uses the principle of high-level drop pressure to transport the enema liquid from the high-level enema bag through a transparent catheter to the enema head inserted into the anus, so as to achieve the purpose of treatment and health care. The existing enema device can be divided into three parts, consisting of a bag for containing the solution, a polymer transparent catheter connected together, and a flexible pipe inserted into the anus. In clinical practice, under the influence of the patient’s own intestinal factors (such as fecal factors, intestinal spasm, peristalsis, tumor compression, poor anal sphincter strength, etc.), psychological factors, and external force factors (posture, etc.), feces or Leakage of enema liquid pollutes the operating area, and the traditional enema method is complicated to prepare materials, requires too much operating space, and the enema bag travel is too long, which will easily cause waste of medicine.

The infusion pipe is tightly connected with the liquid outlet pipe through the threaded joint, and is not easy to fall off.

The above perfusion plug joint is hollow cylindrical, the head of the perfusion plug joint protrudes radially outwards to form a stop and stop part, the outer surface of the head of the perfusion plug joint is an arc surface, A first perfusion hole is opened on the end face of the head of the perfusion plug joint, and at least two second perfusion holes are opened along the length of the wall of the perfusion plug joint, and the tail of the perfusion plug joint shrinks radially inward , forming a pipeline interface at its tail end, and the pipeline interface is connected with the liquid outlet end of the perfusion tube. With this design, the perfusion plug joint is easy to insert into the anus and is not easy to fall off, and the medicinal liquid can be poured through the first perfusion hole and the second perfusion hole.

An anti-leakage pad is sheathed on the above-mentioned perfusion pipe, and the anti-leakage pad is close to the liquid outlet end of the perfusion pipe. With the above solution, during enema, the anti-leakage pad can be adjusted according to the activity of the perfusion tube to prevent the leakage of feces or enema liquid.

The above-mentioned perfusion pipe and perfusion plug joint are integrally formed. This solution facilitates the production of the filling tube and the filling plug.

The above-mentioned perfusion tube is a transparent plastic tube. The transparent plastic tube is convenient for observing the liquid medicine inside.

Beneficial effects: adopting a rotary push type sausage enema device of the utility model, the injection pump can be manually operated for enema, the perfusion amount can be adjusted in real time, and the perfusion progress can be controlled. The switch of the valve assembly can control the opening and closing of the perfusion tube, which is convenient for dressing change The piston rod can precisely control the dosage of medicine. The new type has the advantages of simple and compact structure, few components, small operating space required, and less likely to cause waste of medicines.
