Description

Diversion device and diversion method for intestinal excrement
Technical Field
The invention belongs to the field of medical treatment, and particularly relates to a diversion device and a diversion method for intestinal excrement.
Background
In the treatment of digestive system diseases, a treatment method known as temporary "stoma" is often used. The main principle is that the intestinal canal is dissociated through a surgical operation, one end of the intestinal canal is led out to the body surface, and an opening is formed, so that the excrement (excrement) of the body is discharged out of the body. The stoma is respectively provided with an input end (stoma near-end intestinal canal) and an output end (stoma far-end intestinal canal) of the stoma, the stoma near-end intestinal canal is connected with organs such as stomach, and the stoma far-end intestinal canal is connected with organs such as anus.
When the patient is treated for a period of time and the pathological factors of the patient are relieved, the reduction operation of the enterostomy (i.e. the intestinal tract of the patient is restored to the patient) needs to be considered. Before the operation of the stoma reduction operation, the examination of systems such as abdominal CT, intestinal radiography, enteroscopy and the like is generally carried out to confirm that the pathological factors of the intestinal tract at the far end of the stoma are relieved. However, even after sufficient examination, some patients still receive the stoma, and the disease will recur in the originally pseudo-healed part due to the stimulation of the excrement (feces) in the intestinal tract, such as intestinal inflammation, and the like, and the stoma is forced to be performed again, which not only increases the economic burden of the patients, but also causes great harm to the body and spirit of the patients.
Therefore, in the prior art, in order to detect whether the intestinal tract at the far end of the stoma of the patient is completely healed, the intestinal tract input end and the intestinal tract output end of the patient are communicated for a short time, so that excrement of the intestinal tract at the near end of the stoma of the patient flows into the intestinal tract at the far end of the stoma, and then whether the intestinal tract at the far end of the stoma is healed or not is judged by observing the reaction of a human body.
Disclosure of Invention
The invention provides a novel intestinal stoma excrement diversion device, which aims to detect whether the intestinal canal at the far end of a stoma of a patient is completely healed.
In order to achieve the above object, the present invention provides a diversion device for intestinal feces, comprising an injector and a receiver. The injector is respectively communicated with the peristomal proximal intestinal tract and the peristomal distal intestinal tract, so that excrement discharged from the intestinal tract can be partially injected into the peristomal distal intestinal tract through circulation of the injector.
After the excrement part enters the intestinal tract, whether the intestinal tract at the far end of the stoma is healed or not can be judged by observing whether the human body has adverse reactions or not. At the same time, in order to ensure that the excreta which is not completely discharged into the distal intestine of the stoma can be received, a receptacle is also connected to the injector. When excrement enters the injector, the residual excrement which is not completely injected into the intestinal tract at the far end of the stoma through the cannula enters the container, so that discomfort of a patient caused by overlarge pressure after the injector contains the overlarge excrement is avoided. The container can contain redundant excrement, and can also guide solid excrement in the intestinal tract into the container, so that the solid excrement is prevented from blocking the cannula.
Meanwhile, only by operating the injector, the human excrement can normally enter the intestinal tract. Thus, the health care provider can typically operate the injector for the duration of time to detect whether the patient has healed under predetermined conditions.
Further, the injector holds the chamber for elasticity, and elasticity holds the chamber and can take place to deform under the effect of external force to make and hold the inside excrement that holds the chamber and can inject into the intestinal of stoma distal end better.
The interior of the elastic containing cavity is communicated with the stoma, so that excrement discharged from the stoma can directly enter the elastic containing cavity. And then the excrement is injected into the intestinal tract at the far end of the stoma through the deformation of the elastic containing cavity.
Further, the injector is connected to the stoma distal intestine via a cannula. A cannula is housed in the infuser, the cannula connecting the interior of the infuser to the stoma distal bowel. The cannula is adapted to be inserted directly into the intestine distal to the stoma of the human body, thereby allowing the waste inside the injector to pass through the cannula into the intestine distal to the stoma.
Further, to facilitate insertion of the cannula into the intestine while reducing discomfort to the patient, the cannula is preferably a rubber hose.
Further, the injector is provided with an inlet which can cover the stoma, so that the interior of the injector is communicated with the intestinal stoma. Thus, when the excreta is discharged from the intestine near the stoma, the excreta directly enters the injector, thereby facilitating the injection of the excreta into the intestine at the distal end of the stoma.
Alternatively, a connecting tube can also be provided directly on the injector. The connecting tube may be inserted directly into the intestine proximal to the stoma, thereby allowing fecal matter to pass through the connecting tube into the injector.
Further, when a mode in which an inlet is provided on the injector to collect excrement is used, then a connection part is further connected to the injector. The connection portion may fix the injector on the human body so that the injector does not fall off. Meanwhile, the entrance of the injector can be completely closed to cover the stoma, so that the leakage of excrement from the joint of the entrance of the injector and the human body is avoided.
Furthermore, the connecting part for fixing the elastic accommodating cavity on the human body can be an adhesive part, and the adhesive part is adhered to the human body, so that the elastic accommodating cavity is fixed to the human body.
Further, the flow of excrement towards the receptacle when the injector injects excrement into the intestine is avoided. A valve is then provided at the inlet of the receptacle. When the valve is closed, the passage between the receptacle and the injector is closed and no flow of waste is possible. When the excrement no longer flows to the container, the injector can inject the excrement into the intestinal tract at the far end of the stoma and discharge the excrement through the anus, and the excrement is prevented from flowing to the container and not flowing to the intestinal tract at the far end of the stoma.
Alternatively, the receptacle can be provided directly as a receiving bag which can be folded or clamped by a clamp to the inlet, so that the passage between the receptacle and the injector can be closed.
Further, in order to discharge the excrement stored in the receptacle, a drain outlet is provided on the receptacle. The drain can be opened, and then outwards discharge the inside excrement of container, guarantees that the container can use for a long time.
Or a detachable connection between the holder and the elastomeric injector may be provided. When the excrement is excessive, the container can be separated from the elastic injector and then replaced with a new one.
Another object of the present invention is to provide a diverting method using the above diverting device, comprising the following steps:
step one, excrement of the intestinal tract at the proximal end of the stoma directly enters the interior of the injector through the stoma or the connecting pipe.
And step two, inserting the cannula into the intestinal tract at the far end of the stoma of the human body.
Step three, as the cannula is communicated with the interior of the injector, the excrement contained in the injector can be injected into the intestinal canal at the far end of the stoma through the injector.
The invention has the beneficial effects that: 1. the human waste is received by the injector and then injected into the intestine distal to the stoma. Then, whether the intestinal canal at the far end of the stoma is healed or not can be judged by observing the adverse reaction of the human body.
2. In order to avoid that the injector is not timely guided into the intestinal canal at the far end of the stoma through the cannula after the injector receives too much excrement, so that the pressure of the injector is too high and the patient feels uncomfortable, the injector is also connected with a container. Besides the container can contain redundant excrement, the container can also shunt solid excrement in the intestinal tract into the container, and the pipeline is prevented from being blocked by the solid excrement.
3. The diverting device may be used as a temporary faecal containment device when detection of healing is not required. The injector is then operated to inject fecal matter into the patient's bowel when the patient needs to be examined.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments more apparent, the present invention is described in further detail below with reference to the accompanying drawings and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Embodiment substantially as shown in fig. 1 to 2, a diversion device for intestinal faeces comprises an injector 1 and a receptacle 2, the injector 1 being in communication with an inlet end (stoma proximal intestine) and an outlet end (stoma distal intestine) of a stoma of the intestine, respectively. Thus, when excreta is discharged from the stoma proximal intestine, the excreta directly enters the injector 1, and then the injector 1 injects the excreta into the stoma distal intestine through the cannula 3.
After the excrement is injected into the intestinal tract at the far end of the stoma, whether the human body has adverse reaction can be observed, and whether the pathological factors of the intestinal tract at the far end of the stoma are completely eliminated can be further confirmed. If the human body has no adverse reaction, the human body is recovered, and the enterostomy recovery operation can be carried out; if the human body has adverse reaction, the pathological factors of the intestinal tract at the far end of the stoma are not eliminated, and the human body still needs to continue the treatment and maintain the stoma state.
Also connected to injector 1 is receptacle 2, which receptacle 2 can receive excess waste, so as to avoid discomfort to the patient caused by excessive pressure after injector 1 receives too much waste. Meanwhile, when the excrement contains excessive solids or sticky matters, the container 2 can also timely contain the solids and the sticky matters, and the cannula 3 is prevented from being blocked.
And a sewage draining outlet is also arranged on the container 2. The drain outlet may discharge excrement out of the receptacle 2 when the excrement in the receptacle 2 is excessive.

The inlet of the receptacle 2 is provided with a valve. When the valve is open, the waste can pass directly into the receptacle 2; when the valve is closed, then there is no communication between injector 1 and receptacle 2, so as to avoid the flow of excrement into receptacle 2 when injector 1 injects it into the intestine.
Alternatively, the receptacle 2 can be provided directly as a receiving bag, which can be folded or the mouth of which can be clamped by a clamp, so that the receptacle 2 and the injector 1 are closed.
The injector 1 is embodied as an elastic containing cavity, which is a sealed cavity for containing excrement discharged from the proximal intestine of the stoma (i.e. the end connected to the organs such as the stomach). The elasticity holds the chamber and makes for plastics, and it can take place to deform under the effect of external force (being operator's extrusion force), and then makes the inside excrement of elasticity holding chamber discharge from the elasticity holding intracavity.
Inside the flexible containment chamber is arranged a cannula 3, the cannula 3 being intended to be inserted from an injector into the intestine distal to the stoma (i.e. the end connected to the anus). When the cannula 3 is inserted into the intestine distal to the stoma, the cannula 3 guides the excreta inside the flexible receiving chamber into the intestine distal to the stoma for discharge via the anus.
Since the cannula 3 is fixedly mounted in the inner wall of the injector 1, the cannula 3 is further provided with a first connection port and a second connection port on the side wall in order to communicate the inside of the cannula 3 with the inside of the injector 1. The first port is located on the cannula 3 in the area where the injector 1 is received and the second port is located on the cannula 3 in the area where it is inserted into the human intestine.
In order to enable the cannula 3 to conform more to the human intestine and also to relieve pain in the human body, the cannula 3 is then preferably a rubber hose. And the intubation tube 3 is preferably in a circular arc shape, so that the intubation tube can be better attached to the intestinal tract of a human body.
The injector 1 is provided with an inlet, which is fixed to the human body by a connection 4. While the inlet encloses the stoma and thus enables the discharge of waste from the stoma directly through the inlet into the injector 1.
Or the injector 1 is further provided with a connecting tube which can be directly inserted into the intestinal tract at the proximal end of the stoma, so that the excrement discharged from the proximal end of the stoma directly enters the injector 1 through the connecting tube.
When the manner of providing an inlet on the injector 1 for collecting excrement is used, the stoma is covered in order to enable the injector 1 to be fixed. The inlet of the injector 1 is then also fixedly connected to the connection 4, which connection 4 is intended to be directly connected to the body, so that the injector 1 is fixed to the body.
Meanwhile, after the injector 1 is fixed on the human body, the connecting part 4 can be directly attached to the human body tightly, so that the leakage of the excrement discharged from the stoma is avoided.
Connecting portion 4 specifically is bonding portion, and bonding portion is the ring shape, and bonding portion middle part holds the chamber with elasticity and is connected. The bonding part can be directly bonded on the human body, and simultaneously, the bonding part is connected with the elastic containing cavity, so that the elastic containing cavity is fixed on the human body.
A diversion method applying the diversion device comprises the following steps:
in step one, excrement discharged from the intestine near the stoma can directly enter the injector 1 through the stoma or the connecting pipe. While excess excrement as well as solid excrement enters the receptacle 2.
Step two, the cannula 3 is inserted into the intestinal tract at the distal end of the stoma.
Step three, since the cannula 3 communicates with the inside of the injector, the excreta contained in the inside of the injector 1 is injected into the intestine at the distal end of the stoma by pressing the injector 1 to be discharged through the anus.
The following is further detailed by the specific embodiments: human waste enters the injector 1 from the intestine near the stoma, and the injector 1 injects the waste in the injector 1 into the intestine far from the stoma through the cannula 3.
When too much excrement is discharged from the intestine at the proximal end of the stoma, in order to avoid that the injector does not timely guide the excrement into the intestine at the distal end of the stoma through the cannula after the injector receives the too much excrement, so that the pressure of the injector is too high, discomfort is caused to a patient, and redundant excrement or solid and viscous excrement can be directly received in the container 2. Reference may be made in particular to fig. 2.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
