Description

An inflatable medical anal dilator

technical field

The utility model relates to a medical device, in particular to an inflatable medical anal expander.

Background technique

Defecation is a collection of multiple complex physiological activities. The ability to maintain anorectal control of stool is mainly accomplished by the rectum, pelvic floor muscles and anorectal sphincter. The myenteric plexus of newborns is immature after birth, and intrauterine hypoxia can also lead to a delay in the maturation of the myenteric plexus, and this maturation process does not end until the age of 5. In this case, children may experience relaxation and disappearance of the internal sphincter, anorectal peristalsis disorder or even disappearance, and children may present with constipation, and in severe cases, symptoms of intestinal obstruction may occur. Usually, the voluntary control of reflex defecation is after the baby is 18 months old and the development of the central nervous system of defecation is relatively mature. Therefore, it is very meaningful for the baby to perform defecation training before and after learning to walk. The theoretical basis of anal expansion and defecation training, through the passive biofeedback training of anal expansion, stimulates the tissue next to the puborectalis muscle and the expansion receptors of the puborectalis itself, causing the desire to defecate and normal defecation.

Existing anal dilators are all made of metal rods, aluminum alloy rods and plexiglass rods with large conical radians at the top and no curvature. The straight rod has no certain curvature, and you will feel pain and discomfort when dilating the anus. If the operation is not done properly, the anal dilator will easily slide into the intestinal cavity, and surgery is required to remove it. The patent number is "ZL 200430014800.6", and the Chinese patent titled "Medical Anal Expander" is a straight rod-shaped anal expander made into a curved cylinder according to the physiological curvature of the rectum. The body is parallel and fixed, which can prevent the anal expander from rotating up and down, left and right, and avoid intestinal perforation; there is also a round hole at the end that can be threaded to prevent the anal expander from sliding into the intestinal cavity. However, the anal expander only acts on the anorectal sphincter and the pelvic floor muscle, and cannot stimulate the rectal wall, and the existing anal expander is easy to fall off, and cannot adjust the diameter.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described. An inflatable medical anal dilator as shown in Figures 1 to 5 is a curved cylinder made according to the physiological curvature of the rectum, and its top is conical, and the arc tangent of the cylinder 1 starts from the The rear end of the anal organ measures 1/3 of the length of the cylinder, the angle β between the tangent and the cylinder is 8° to 16°, the cone angle α at the top of the anal expander is 20° to 55°, and the diameter of the anal expander is 11° to 50°. 27MM, length 19~20CM, can be set into different models, adults and children can use it. And there is a scale layer 8 on the surface of the curved cylinder 1, the scale value range of the scale layer 8 is 9-11cm, the initial scale is set at the top of the cone, and the use length can be known without measuring during use. easy and convenient. An inflatable air bag 2 is fixedly set at a position 4-6 cm long at the front end of the curved cylinder 1, an inflatable tube 3 is provided in the cylinder 1, and an inflatable port 4 is provided at the part of the cylinder 1 placed on the inflatable air bag 2, One end of the inflation tube 3 communicates with the inflation port 4, and the other end stretches out from the afterbody of the cylinder 1, and an inflation joint 10 is provided at the tail end of the inflation tube 3 for convenient inflation.

As shown in Figures 1 and 2, an annular groove 5 is provided at a position 4-6 cm long at the front end of the curved cylinder 1, and the mouth of the inflatable airbag 2 is sealed in the annular groove 5. When this method is adopted, In order not to affect the normal use of the anal dilator, the inflatable air bag uses a relatively thin soft rubber sleeve, which can be made of a material similar to a condom. When it is not inflated, it can be attached to the anal dilator and lubricated. Insertion is easy and does not cause undue discomfort to the patient.

As shown in Fig. 3, a 4-6cm long airbag sleeve part 6 can also be provided at the insertion end of the curved cylinder 1, the diameter of the airbag sleeve part 6 is 0.4-1cm smaller than the diameter of the tail end of the cylinder 1, An inflatable airbag 2 is provided on the outside of the airbag sleeve part 6, and the mouth of the inflatable airbag 2 is sealed and connected with the cylinder 1 through the connecting ring 7. When this method is adopted, the inflatable airbag 2 can adopt a rubber sleeve with a slight thickness, such as Pressure rubber balls, rubber gloves and other materials can first fix the opening of the inflatable air bag 2 on the connecting ring 7, and then set the connecting ring 7 on the connection between the anal expander air bag sleeve part 6 and the tail end without the air bag sleeve place, and seal it, the connecting collar can use a threaded collar, which is convenient to tighten and remove for replacement. In the uninflated state, as shown in Figure 4, the front end of the inflatable airbag 2 is conical with the same radian as the insertion end of the cylinder 1, and forms an integral body with the part of the cylinder 1 where the inflatable airbag 2 is not provided. In the inflated state, as shown in FIG. 5 , the inflated airbag 2 forms an inflated ball.

In order to control the use length of the anal expander, an annular ferrule 9 can be provided on the anal expander, the annular ferrule 9 shown can be a rubber sleeve, and the annular ferrule 9 is arranged on a cylinder whose length is 9-11 cm from the top. space, and can move on the cylinder 1 to prevent the anal dilator from slipping into the intestinal cavity and reduce medical accidents.

In order to prevent the anal expander from slipping into the intestinal cavity during use, a half-section is formed from the starting point of the rear end of the anal expander to 3.5 cm from the rear end, and a perforation 11 for a tether is provided on the half-section.

When the utility model is used, the anus is continuously expanded for 30 minutes every day, which can effectively relax the rectal stenosis. In the biofeedback training of defecation, not only the anorectal sphincter and pelvic floor muscles are stimulated, but also the rectal wall is stimulated. More fully achieve the stimulation of the three parts of the human body to maintain the anal canal and rectum to control the stool, and can better complete the biofeedback training process, stimulate intestinal peristalsis, increase the intensity of intestinal peristalsis, accelerate intestinal transportation, and smooth stool and gas Discharge, solve the constipation problem, and also reduce the occurrence of preoperative and postoperative complications (mainly enterocolitis). Anal dilation for postoperative anastomotic stenosis or rectostomy stenosis can relax the snout and mouth; for neonatal Hirschsprung children with constipation, abdominal distension, and poor physical condition, conservative treatment with different types of anal dilators can make the Newborns pass through the initial dangerous stage, improve the general condition, and prepare for the operation at an appropriate time in the future. According to our research and literature reports: most children with early mild NID (homologous Hirschsprung’s disease) were treated conservatively through anal dilation, and satisfactory results were obtained.

In addition, in order to achieve a one-time disinfection effect, we will design a disposable plastic finger cot that matches with the anal expander.

The indications for the treatment of the said anal dilator include: chronic constipation, ultra-short-segment type, short-segment type Hirschsprung’s disease, early mild NID, abdominal distension, tight anal sphincter or anal stenosis, post-congenital anal atresia, Anastomotic stenosis after Hirschsprung operation, and enterostomy stenosis. Conservative treatment with anal expander will be widely used in pediatric surgery, anorectal surgery and chronic constipation patients nationwide.
