Problems solved by technology

Traditional anal drug delivery devices generally use ordinary syringes, but when the liquid medicine is injected into the rectum, if the muscles in the anus lose their ability to tighten, the liquid medicine will flow out quickly and cannot exert its efficacy
In addition, if the syringe is used to inject medicine into the rectum through the catheter, if the syringe needs to be used to draw new medicine several times, the medicine in the rectum will flow back along the catheter during the medicine taking
General medical staff will use meta

Abstract

The invention discloses an anus administration device, and belongs to the field of medical appliances. The anus administration device is characterized by comprising a flushing pipe and a check valve; the flushing pipe comprises a liquid injecting end and a liquid outlet end; a flushing hole is formed in the side wall of the liquid outlet end of the flushing pipe; an expanding device sleeves the middle part of the flushing pipe, and is communicated with an outer sleeve; the check valve comprises a primary check valve and a secondary check valve; the primary check valve is mounted at the front end of the flushing pipe or the middle part of a pipe body; the secondary check valve is mounted on the outer sleeve. The anus administration device can prevent a medicinal liquid from leaking outwards or returning along a pipeline while facilitating rectal administration, and ensure that the medicinal liquid fully plays a pharmacological function in a rectum; the second technical problem to be solved by the anus administration device is that the temperature and the speed of the medicinal liquid which is injected into the rectum are appropriate through a heat exchange effect, so that an uncomfortable reaction caused by a patient cannot be caused, and the anus administration device is favorable to giving full play to the pharmacological function.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an anal drug delivery device. Background technique [0002] Rectal administration refers to the drug delivery method that sends the drug into the intestine through the anus, enters the large circulation through the rapid absorption of the rectal mucosa, and exerts the drug effect to treat systemic or local diseases. [0003] The way of rectal administration generally requires the assistance of an anal administration device. Traditional anal drug delivery devices generally use ordinary syringes, but when the liquid medicine is injected into the rectum, if the muscles in the anus lose their ability to tighten, the liquid medicine will flow out quickly and the drug effect will not be exerted. In addition, if the syringe is used to administer medicine to the rectum through the catheter, if the syringe needs to be used to draw new medicinal liquid several times, the medic...
