Description

Flushing head device and flusher

Technical Field

The utility model belongs to the technical field of flushing devices related to medical treatment. In particular to a flushing or medication device suitable for anus-related irrigation in anorectal surgery, in particular to a disposable anus flushing head device and an anus flusher.

Background

The anus is one of the important excretory organs of the human body, and most of toxins are discharged through the anus; cleaning of the anus is one of the important environmental conditions for maintaining the health of the anus.

Nowadays, most people have a habit of sedentary work; due to the fact that modern people have high working pressure, mental stress, irregular work and rest for a long time and poor eating habits, more and more people are prone to suffering from diseases such as hemorrhoids, constipation, anal sinusitis and proctitis and sub-health diseases related to anorectal pain. Pregnant women are also a high-risk group of such conditions. In the rehabilitation process of sub-health conditions such as hemorrhoids and constipation, the anus needs to be flushed regularly to keep clean, or the rectum is filled with medicine through the anus to induce defecation, the whole process usually needs a long time, and the work burden of patients and medical care is increased if professional medical care is needed for a long time. The simple devices are particularly needed to enable ordinary non-professional personnel to wash or fill the anus by themselves, and the simple devices can be operated at home by themselves, so that privacy can be protected, and medical resources can be saved.

In practice, there is a continuing need for anal and intestinal wound cleansing and administration to those who have undergone anal or intestinal surgery. Cleaning and applying medicine to the anus and intestinal wounds are usually performed by medical workers during or shortly after surgery; these cleaning processes can be very professional and are not prone to damage to the anus and the intestine. However, in the subsequent rehabilitation stage, the patient is generally discharged and then returns to the hospital for washing and dressing change, so that the burden of the patient and medical care is increased; and because near anus portion relates to the privacy, if can let the patient clean and go up the medicine by oneself, can not only protect patient's privacy, can also save patient's energy, alleviate medical personnel's work burden.

Some of the irrigation heads and irrigators of the prior art for women generally do not have a lubrication device and are shaped and sized for women only and are not suitable for patients to clean and apply medicine to the anus and intestinal wounds by themselves. The washing head and the washing device in the prior art have no structures for preventing backflow and liquid leakage, so that a plurality of problems exist in the self operation of a patient; one phenomenon is reflux phenomenon, which is the phenomenon that substances in the rectum enter the flushing head and the flushing device through the liquid medicine outlet after the flushing head and the flushing device are inserted into the anus; the second is that the leakage and dripping phenomena are easy to occur, and the situations that the administration is not in place and the dosage is insufficient can occur; thirdly, the rectum is easily damaged due to overlarge pressure of liquid medicine output outwards by a liquid medicine container in a common flushing head and a flushing device, the liquid medicine cannot be delivered to a specified position due to the overlarge pressure, the liquid medicine cannot easily stay at the stay position and can leak downwards along a gap when the pressure is not proper, substances in the rectum are usually carried in leaked liquid, and the operation position and an operator are easily polluted due to the unclean liquid.
