Description

Disposable colorectal irrigation and drainage catheter

technical field

The utility model relates to a disposable irrigation and drainage tube, in particular to a disposable colorectal irrigation and drainage tube.

Background technique

Rectal and anal canal injuries are common in trauma or iatrogenic injuries. Due to their anatomical and physiological characteristics, there are often formed feces in the rectum with high bacterial content. After injury, feces pollute the wound surface and easily lead to infection, leading to diffuse peritonitis in the abdominal cavity or post-infection. Not easy to localize, even endanger the patient's life. Due to the complexity of the condition after injury, there are many clinical treatment methods, which are generally divided into surgical treatment and non-surgical treatment. But no matter what kind of treatment is adopted, fast and effective removal of feces in the intestinal tract, reducing local pollution and pressure in the intestinal tract is a necessary measure for successful surgery or conservative treatment.

In order to quickly and effectively remove feces in the intestinal tract of the injured part, reduce local pollution and pressure in the intestinal tract, the traditional method is to perform a cleansing enema. Although there is a method of oral whole intestinal lavage, it is not suitable for rectal and anal canal injuries that require fasting and drinking.

For such patients, the currently used cleansing enema method is to use the anal canal to carry out cleansing enema. The anal canal is a circular tube, one end is the lavage fluid inlet, and the other end is the lavage fluid outlet. There is a through hole on the tube wall near the lavage fluid outlet. When there is formed feces in the intestinal tract, The outlet of the lavage fluid may be blocked. At this time, the side hole can be used as the outlet of the lavage fluid, so that the lavage fluid can be perfused into the intestinal tract smoothly. The operation process is as follows: the patient lies on the left side with knees bent, the end of the anal canal is lubricated and inserted into the anus 7cm to 10cm. Repeat this until the excrement is clear and free of dung. This method of repeated intubation and multiple irrigations requires more operations, which is likely to cause congestion and edema of the intestinal mucosa, and also increases the probability of damage to the perianal skin and intestinal mucosa; and due to the large amount of lavage, most patients with With abdominal wounds, it is extremely inconvenient for patients to defecate in bed, which may easily cause contamination of bed sheets and clothes; at the same time, it also increases the workload of nursing care and cannot improve work efficiency.

The lavage chamber communicates with the lavage fluid inlet tube fixed on the drainage tube body.

The irrigation fluid inlet tube is located outside the drainage cavity.

The lavage chamber and the drainage chamber are formed by dividing the lumen of the drainage tube body by the partition wall.

The lavage chamber and the drainage chamber are formed by separate pipes, and the pipes constituting the lavage chamber are fixed on the pipes constituting the drainage chamber to form a drainage tube body.

The pipeline forming the lavage cavity is inserted into the pipeline forming the drainage cavity.

The outlet end of the lavage chamber exceeds the inlet end of the drainage chamber.

There are more than two side holes.

The side holes are distributed on the pipe section with an axial length of 5-10 cm from the end surface of the inlet end of the drainage cavity.

The diameter of the side hole is 0.8-1.0 cm.

The beneficial effect of the utility model is that only one intubation is needed, and the patient can achieve the purpose of comfortable defecation and intestinal cleaning without defecating, and the operation is simple, pain-free, and high in efficiency.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figure 1, the existing anal canal has only one tube, which is used for infusing lavage fluid, which requires repeated intubation and multiple irrigations, which causes severe pain to the patient and increases the workload of nursing.

As shown in Figure 2, the disposable colorectal irrigation and drainage tube of the present invention adopts a double-chamber design, which includes a drainage tube body 1, and the drainage tube body 1 has a lavage cavity 3 and a drainage cavity that are separated from each other and flow in opposite directions. 4. The opposite flow direction means that the flow direction of the lavage chamber 3 is from the outside to the body, while the flow direction of the drainage chamber 4 is from the body to the outside. Hole 2, the effect of side hole 2 is equal to the effect of side hole 13 in existing anal canal 10, and lavage cavity 3 imports lavage liquid from outside to body, and drainage cavity 4 then leads out the waste mixed with feces from inside to outside. Liquid can be performed continuously without interruption, without repeated intubation, simple operation, low pain, and high efficiency.

Further, in order to reliably and conveniently introduce the lavage fluid, the lavage cavity 3 communicates with the lavage fluid inlet pipe 5 fixed on the drainage tube body 1, and the drainage tube can be connected with the irrigation fluid through the irrigation fluid inlet tube 5. Storage device connection.

Usually, the irrigation fluid inlet pipe 5 is selected to be located outside the drainage chamber 4 so as not to affect the smooth discharge of the waste fluid.

As shown in FIG. 2 , the lavage chamber 3 and the drainage chamber 4 are formed by separating the lumen of the drainage tube body by a partition wall 6 .

In addition, the drainage tube in the following form can also be used: the lavage chamber 3 and the drainage chamber 4 are formed by separate pipes respectively, and the pipes forming the lavage chamber 3 are fixed on the pipes forming the drainage chamber 4 to form the main body of the drainage tube 1, so that drainage can be performed with only one effective intubation operation.

In the above structure, it is preferable that the pipeline constituting the lavage cavity 3 is inserted into the conduit constituting the drainage cavity 4, so that the outer contour of the insertion section of the drainage tube body 1 is relatively smooth, so as to weaken the discomfort of the patient.

Preferably, the outlet of the lavage chamber 3 exceeds the inlet end of the drainage chamber 4, so as to ensure that the lavage fluid can reach the intubation position, so that the lavage fluid can be reliably introduced.

Preferably, there are more than two side holes 2, so that the irrigation tube is less likely to be blocked.

According to clinical experience, the side holes 2 are distributed on the pipe section with an axial length of 5-10 cm from the inlet end surface of the drainage chamber 4, which can ensure smooth drainage.

According to clinical experience, the diameter of the side hole is 0.8-1.0 cm, which can ensure smooth drainage.

In the above case, the side holes 2 can be symmetrically distributed with respect to the centerline of the drainage tube body, which is convenient for the hole processing of the side holes. Of course, the distribution can also be asymmetrical.

Example:

As shown in Figure 2, the disposable colorectal lavage and drainage tube of the present invention includes a drainage tube body 1, and the inner cavity of the drainage tube body 1 is separated by a partition 6 into a lavage cavity 3 and a drainage cavity 4 that are separated from each other and flow in opposite directions. The lavage chamber 3 communicates with the lavage fluid inlet pipe 5 fixed on the drainage tube body 1, and the side hole 2 with a diameter of 1 cm is provided with six symmetrically arranged through holes on the wall of the inlet end of the drainage chamber 4. The outlet end of the lavage chamber 3 is 3 mm beyond the inlet end of the drainage chamber 4, and the wall of the drainage chamber 4 near the inlet end is provided with six side holes 2 symmetrically arranged on both sides, and the distribution length of the side holes is L1=8cm.

The operation process is as follows: the patient takes the knee-bend position on the left side, slowly inserts the disposable colorectal irrigation drainage tube from the anus upwards, and inserts the drainage tube 4 into the drainage cavity above the wound according to the injured part and degree of damage of the rectum and anal canal About 10 to 15 cm away; fix the colorectal irrigation and drainage tube around the anus; connect the outlet of the drainage chamber 4 with the drainage bottle; connect the irrigation fluid inlet tube 5 with the irrigation fluid storage device, turn on the switch of the storage device, Put in the lavage solution to achieve continuous lavage until the intestinal tract is discharged without fecal residue.

Its advantages are: first, the drainage tube has a double-lumen structure, which can be continuously lavaged and has high efficiency; second, the multi-side hole design of the drainage tube body can prevent feces from blocking the tube, resulting in poor drainage; third, feces It is directly discharged from the outlet of the drainage tube body, and the patient does not need to defecate frequently, which is conducive to the recovery of the injured patient; fourth, because only one intubation is required, the congestion and edema of the intestinal mucosa, and the damage to the perianal skin and intestinal mucosa of the patient are greatly reduced The probability of; fifth, reducing the workload of nursing, effectively improving work efficiency.
