Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1, it is a schematic structural diagram of a self-service nursing device after anorectal stenosis according to embodiment 1 of the present invention (the positioning balloon and the dilation balloon are not filled with gas or liquid). As shown in fig. 2, the self-nursing device after anorectal stenosis operation according to embodiment 1 of the present invention is used (the positioning balloon and the dilation balloon are opened). As shown in fig. 1 and 2, the self-service nursing device of the present invention comprises: a central pipe column 1, a positioning air bag 2 and an expansion air bag 3 which are sequentially sleeved outside the central pipe column 1, and a first connecting pipe and a second connecting pipe (not shown); the positioning balloon 2 and the dilatation balloon 3 are in contact or close proximity. The central pipe column 1 is slender, and one end close to the positioning air bag 2 is bullet-shaped, so that the central pipe column can be conveniently extended into the anus of a patient after the anorectal stenosis. The positioning balloon 2 plays a positioning role to help the patient judge whether the device has crossed the stenosis and meets the insertion depth requirement.

Crohn's disease anorectal stenosis is one of the perianal lesions, and the stenosis is located in the anal canal and lower rectum. The stenosis is divided into membranous stenosis less than 2cm and tubular stenosis more than 2cm, the length of the tubular stenosis (the length of the proximal end of the stenosis from the anal margin) is more than 2-7cm, and generally not more than 10 cm; the diameter of the narrow tube cavity needing to be treated is mostly less than 1cm, the diameter of serious narrow can reach 0.2-0.5cm, and the diameter of the narrow part passing through the treatment can reach 1.2-1.5 cm.

Because the narrow postoperative of anal canal rectum, the doctor can inform the length of its narrow portion of patient, therefore, adopt the utility model discloses a during the device, can directly with the utility model discloses a device inserts the degree of depth that exceeds narrow length, behind the insertion device, opens location gasbag 2, makes the diameter of location gasbag 2 exceed the narrow portion diameter, if the patient does not have painful sensation, explain location gasbag 2 has crossed the narrow section, draw back the device this moment and stop when having the resistance (observe the depth of insertion and measure narrow length unanimous in the art), explain this moment to expand the gasbag and fix a position at narrow position, can open expansion gasbag 3, carry out complete anus expansion to narrow portion, realize expanding the rational use of anus ware.

The center pipe column 1 is hollow, a first injection port communicated with the positioning air bag 2 is arranged on the pipe wall, a second injection port communicated with the expansion air bag 3 is further arranged on the pipe wall of the center pipe column 1, the first injection port is connected with the gas injection device or the liquid injection device through a first connecting pipe stretching into the center pipe column 1, and the second injection port is connected with the gas injection device or the liquid injection device through a second connecting pipe stretching into the center pipe column 1. Therefore, the positioning balloon 2 and the expanding balloon 3 can be inflated with gas or liquid. The positioning air bag 2 and the expansion air bag 3 need to be connected with a gas injection device or a liquid injection device through different connecting pipes so as to be beneficial to the respective control of the positioning air bag 2 and the expansion air bag 3. The pressure of the air bag is controlled by the gas injection device or the liquid injection device, so that the expansion diameter can be controlled, the violent anus expansion is avoided, and the safety and painlessness are realized.

The positioning air bag 2 is in a cuboid shape, a square shape or a spherical shape or other shapes after being expanded, and the expansion air bag 3 is in a cylindrical shape after being expanded. The material of the dilatation balloon 3 may have a certain elasticity.

The gas injection device or the liquid injection device can select a needle cylinder, or can be a gas injection or liquid injection machine with a pressure display, and a patient can know the expansion sizes of the positioning air bag 2 and the expansion air bag 3 according to a pressure gauge.

The method of use of example 1 is illustrated below:

narrow postoperative patient of anal canal rectum according to the doctor instruction, uses every day the utility model discloses a self-service nursing device expands the anus. Before use, the first connecting pipe and the second connecting pipe are respectively connected with an air injection machine. The self-service nursing device is integrally slender and easily extends into the anus. After the patient stretches into the anus for a certain distance, the patient uses the air injection machine with the pressure gauge to open the positioning air bag 2 to the specified size, if the patient does not feel pain, the device is pulled back until resistance exists, and the device stops (the observation insertion depth is consistent with the stenosis length measured in the operation), and the situation shows that the expansion air bag is positioned at the stenosis part. The patient starts to inject gas into the expanding air bag 3, and whether the expanding air bag reaches the required diameter is judged through the pressure gauge. After the anus is expanded, the air in the positioning air bag 2 and the expanding air bag 3 is released, and the device is drawn out. The patient can reduce the recurrence rate of postoperative anal stenosis and the rate of need of proximal intestine tube stoma through anus dilatation.

Example 2

As shown in fig. 3, the self-nursing device after anorectal stenosis in example 2 is compared with the device in example 1 by adding an elastic balloon 4 sleeved outside the dilatation balloon 3.

The elasticity of the elastic balloon 4 is greater than that of the dilatation balloon 3; when the interior of the expansion bladder 3 is not filled with gas or liquid or when gas or liquid has been discharged, the elastic bladder 4 tightens the expansion bladder 3 outside the center pipe string 1.

The dilatation balloon 3 of example 2 is made of a material having a small elasticity. After the gas or liquid is filled, the shape and size of the expanding balloon 3 are stable, and the expanding diameter can be controlled according to the pressure. Since the expansion balloon 3 having a smaller elasticity is difficult to tighten on the outside of the center column, an elastic balloon 4 is designed for tightening the expansion balloon 3 on the outside of the center column. When the expanding balloon 3 is filled with gas or liquid, the elasticity of the elastic balloon 4 is large and does not affect the effect of expanding the balloon 3.

The device of embodiment 2 tightens expansion gasbag 3 in the center tube outside through elasticity gasbag 4, is favorable to alleviateing the misery that the device inserted in the anus, also is favorable to realizing the reuse of device.

In conclusion, the device of the utility model can control the pressure of gas injection or liquid injection, can be used by self, and is safe and painless; the positioning balloon is designed, so that the position needing anus expansion can be accurately positioned; the expansion air bag can be made of a material with smaller elasticity so as to better control the expansion diameter; the expansion air bag is tightened outside the central pipe column by the elastic air bag, so that the pain of the device inserted into the anus is relieved, and the device is reused.
