Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the present invention provides a retention enema device for radiation enteritis, which aims to provide a retention enema device that can accurately deliver medicine to the damaged part and make the patient easily retain the medicine liquid. Specifically, the method comprises the following steps:

the retention enema device comprises an enema sheath 1 and a soft catheter 2, wherein the enema sheath 1 provides guidance for the soft catheter 2 inserted into the intestinal tract of a patient, and the enema sheath 1 can prevent liquid medicine in the intestinal tract of the patient from overflowing.

Example 1:

the enema sheath 1 comprises a guide sheath 101, a sheath head end 102 and a rubber filling bag 103, wherein the guide sheath 101 is of a hollow structure, the sheath head end 102 is arranged at the proximal end of the guide sheath 101, and the soft catheter 2 penetrates through the sheath head end 102 and extends to the hollow interior of the guide sheath 101 _.

When in use, the guide sheath 101 is firstly installed at the entrance of the intestinal tract, the soft catheter 2 is inserted into the guide sheath 101 from the sheath head end 102 at the proximal end of the guide sheath 101, the soft catheter 2 extends into the intestinal tract of a patient under the guiding action of the guide sheath 101, and the length of the soft catheter 2 entering the intestinal tract can be freely adjusted according to the position of a lesion of the patient. Specifically, the method comprises the following steps:

along the outer side wall of the flexible conduit 2 there is provided a graduation mark 202 extending along the wall of the conduit. The depth of the soft catheter 2 into the intestinal tract can be accurately known by observing the graduation marks 202 on the soft catheter 2 outside the sheath head end 102. The side wall of the far end of the soft catheter 2 is provided with a plurality of liquid seepage holes 201. The liquid medicine acts on the diseased part of the intestinal tract through the plurality of liquid seepage holes 201, so that the liquid medicine can be effectively absorbed.

Preferably, the length of the soft catheter 2 is 22-26 cm, and the soft catheter is suitable for the treatment of intestinal tracts of normal human bodies.

Preferably, a through hole 106 for penetrating the flexible catheter 2 is provided at a central portion of the sheath head end 102, and an outer sidewall of the sheath head end 102 is provided with an anti-slip gear structure. Since the intestinal tract is in a state of peristalsis at all times, the guide sheath 101 inserted into the inside of the intestinal tract is easily extruded. The anti-skid gear structure is beneficial to preventing the sheath head end 102 from rotating or laterally moving in the using process, so that the stability of the enema sheath 1 is improved, and the subsequent regulation of the soft catheter 2 cannot be interfered. The inner side wall of the sheath head end 102 is made of rubber. That is, the through hole 106 is made of rubber. The rubber material has elastic property and good sealing effect, and liquid between the through hole 106 and the soft catheter 2 is not easy to seep out.

Further, the length of the guide sheath 101 is 9-12 cm, preferably 10cm, and the length can ensure that a patient is in a comfortable state when the guide sheath 101 is inserted into an intestinal tract.

Example 2:

the rubber filling bag 103 is integrally formed and sleeved on the periphery of the guide sheath 101_ in a sleeving manner, an injection channel 105 communicated with the rubber filling bag 103 is arranged on one side of the rubber filling bag 103 close to the sheath head end 102, and a valve 107 is arranged on the injection channel 105. The valve 107 is closed to make the rubber-filled bag 103 in a closed state.

The physiological saline or gas is injected into the filling rubber bag 103 through the injection channel 105, so that the filling rubber bag 103 is expanded in a spherical shape to clamp the rectum at the far end of the guide sheath 101, and the functions of fixing and preventing the enema from being leaked are achieved.

Preferably, an injection tube hole 108 for the injection channel 105 to pass through is provided on the sheath head end 102. The rubber-filled sac 103 can be injected from the outside of the intestinal tract, and the interference to the affected part is reduced.

As a preferred embodiment: a limiting cylinder 109 is arranged at the outer end of the filling rubber bag 103, and a plurality of pressure equalizing holes 110 are uniformly distributed on the side wall of the limiting cylinder 109. Considering that if the filling rubber bag 103 is directly filled with gas or liquid, concentrated pressure is easily formed at the inlet of the intestinal tract to cause discomfort for the patient, the pressure after the filling rubber bag 103 is filled is uniformly distributed in the pressure equalizing hole 110 through the limit of the limiting cylinder 109, so that the pressure is uniformly distributed, and the comfort of the patient is improved.

In another embodiment, the sheath head 102 may be configured as a screw thread (not shown), and may be connected to a syringe or an enema bag, which the patient can self-enema at home.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
