Compared with the prior art, the beneficial effects of the utility model are:

The utility model provides an enema device for intestinal administration. After the medicine is poured into the enema bag from the feeding port, the air is squeezed into the enema bag through a compressed air pump, thereby forcing the medicine to flow out from the hose, which can be used for The enema administration of the viscous medicine solves the problem that the viscous medicine cannot be enema-administered smoothly. The utility model is provided with a first one-way valve and a second one-way valve. When the air pump is compressed, the first one-way valve is closed and the second one-way valve is opened. The gas in the air pump enters the enema bag. When the air pump relaxes , the first one-way valve is opened, the second one-way valve is closed, and the air enters the air pump from the intake pipe, so repeated compression of the air pump can ensure that the air pump continuously pumps air into the enema bag, providing pressure for the medicine to flow out And power, so that more viscous drugs can also be administered through the hose. Moreover, since the screw cap and the feeding port are provided with matching threads, the screw cap is not easy to collapse even under the internal pressure of a large sausage bag after being covered on the feeding port, which can prevent the medicine from accidentally flowing out from the feeding port. cause waste. Moreover, the nut is connected to the enema bag by the first connecting piece, and there is no need to worry about the accidental loss of the nut when the nut is unscrewed, which has the advantage of being convenient to use. In addition, when the pressure inside the enema bag is too high, the excess air can be discharged through the exhaust pipe, and the exhaust valve on the exhaust pipe can also regulate the exhaust flow, thereby preventing the enema bag from leaking or leaking due to excessive internal pressure. The explosion ensures the safety of the enema administration process.

Further, the utility model is provided with a funnel, the funnel can be installed on the feed port, when the medicine is too viscous to be poured into the enema bag, it can be poured through the funnel, which is convenient for filling the medicine, and the funnel is connected to the enema bag through the second connecting piece. On the enema bag, it is very convenient to take. There is also a needle injection port with a cover on the enema bag. When it is necessary to add medicine, the needle can be used to add medicine to the enema bag through the needle injection port; After the medicine is extracted, it is injected into the enema bag through the injection port of the needle tube, so that the viscous medicine can also be poured into the enema bag, so as to ensure the smooth progress of the enema administration in the next step. The volume scale on the enema bag is convenient for observing the amount of medicine infused. The air intake flow valve on the trachea can control the flow rate of air entering the enema bag, so that the pressure in the enema bag can be maintained at an appropriate level. The discharge flow valve on the hose can control the outflow speed of the drug, thereby controlling the drug delivery speed, ensuring the residence and action time of the drug, and improving the curative effect. The end of the hose is coated with lubricating oil, which can avoid accidental scratches caused by inserting the hose into the patient's intestinal tract, facilitate the smooth insertion of the hose, and avoid the steps of applying lubricating oil on site by medical staff, saving time, and the protective film can Protects hoses and lubricating oil, clean and hygienic. Side holes at the end of the hose allow for even dosing. The length scale on the hose is convenient for knowing the insertion depth of the hose, so as to control the administration position more accurately. Therefore, the enema device provided by the utility model has good safety, high control ability to the enema administration process, convenient use, simple structure, and low cost. The perfusion can take many ways, which can be selected according to the actual situation. It has a wide range of applications and has a good clinical application prospect.
