Description

Technical Field

[0001] The invention relates to the technical field of anal dilators, in particular to anal dilators. Background Art

[0002] After anorectal surgery for hemorrhoids, anal fistulas, anal fissures, etc., there will be local surgical wounds. Because the anus is usually in a contracted state, the wound is in a squeezed state for a long time and cannot be in a normal circumference. If the wound is in this state for a long time, it will cause local wound fibrosis and adhesion, resulting in anal stenosis, which will lead to difficulty in defecation. Therefore, patients with anorectal surgery need anal dilation after surgery, that is, to expand the anal canal to prevent anal stenosis. When dilating the anus, the patient will have obvious swelling and pain, and the patient is very scared. At present, there are several methods for anal dilation: 1. Natural anal dilation: that is, to expand the anus by discharging formed stool. 2. Manual anal dilation: Generally, medical staff insert fingers into the anal canal, expand the anus back and forth, or put 2-3 fingers into the anus for a certain time to achieve the purpose of anal dilation. 3. Use an anal dilator to dilate the anus: Use a slightly blunt, cylindrical and hard anal dilator with a round head to dilate the anus and maintain it for a certain time to achieve the purpose of anal dilation. This anal dilator is composed of different diameters. The initial suitable anal dilator is selected according to different people and the degree of anal canal stenosis, and the diameter is gradually increased to reach the required size, thereby achieving a normal anal canal circumference. The current methods have the following shortcomings: 1. Natural anal dilation is achieved by one's own defecation, but the maintenance time is short and cannot reach the required anal dilation time. Most patients need to combine other anal dilation methods to prevent anal stenosis. 2. Manual anal dilation is mostly performed by medical staff, but the time that is prone to anal stenosis is mostly the recovery period after discharge. During this period, medical staff cannot intervene with manual anal dilation in time, which can easily cause anal stenosis. 3. Anal dilator anal dilation, the existing anal dilators are all rigid columnar anal dilators of fixed size, which are difficult and painful for patients to insert by themselves, and large-scale activities are prone to cause additional damage. They are large and fixed, inconvenient to carry, and the diameter cannot be adjusted at will. Summary of the invention

[0003] The object of the present invention is to provide an anal dilator to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions: An anal dilator, comprising: A gas injection seat, the gas injection seat is connected to the gas guide pipe; An air injection pipe, the air injection pipe is fixedly connected to the air injection seat, and a plurality of air outlet holes are arranged on the pipe wall; A rubber airbag is sleeved on the outside of the air injection tube and fixedly connected to the air injection seat, and is used to adjust the support size in coordination with the liquid or gas delivered by the syringe.

[0005] The limiting balloon is arranged outside the rubber airbag, surrounds the rubber airbag, and is fixedly connected to the air injection seat at the bottom. It is used to expand and shape with the expansion of the rubber airbag, while limiting the unlimited expansion of the rubber airbag to achieve an outward support effect.

[0006] An air guide tube, one end of which is fixedly connected to the air injection seat, and the other end of which is connected to the syringe.

[0007] As a further solution of the present invention: the gas injection seat also includes: an air guide tube limiting groove, which is arranged on the shell wall of the gas injection seat on the side away from the gas injection tube, and is used to achieve guiding and positioning of the gas guide tube.

[0008] As a further solution of the present invention: a retaining ring is fixedly connected to the outside of the gas injection seat near one end of the gas injection tube to limit the gas injection seat to be located outside the anus and limit the insertion depth of the gas injection tube into the anus.

[0009] As a further solution of the present invention: it also includes: a pushing frame, which is arranged on the outside of the gas injection seat and is clamped with the retaining ring to cooperate with the air guide tube limiting groove to limit the air guide tube and assist in pushing the device into the anus.

[0010] As a further solution of the present invention: it also includes: a protective cover, which is arranged on the outside of the air injection pipe and is threadedly connected to the retaining ring, and is used to cooperate with the retaining ring to achieve isolation and protection of the air injection pipe, the rubber airbag, and the limiting balloon.

[0011] Compared with the prior art, the present invention has the following beneficial effects: When the device is in operation, the air injection tube with a rubber airbag and a limiting balloon is inserted into the anus inside the anus, and the syringe inputs liquid or gas into the air injection seat through the air guide tube to realize the gradual expansion of the rubber airbag and the limiting balloon. The expansion size is controlled according to actual needs. Compared with the prior art, this application has the following problems: 1. The natural anal dilation of feces is short-lived and cannot reach the required anal dilation time, and the expansion force is not enough. Most patients need to combine other anal dilation methods. 2. Manual anal dilation is mostly performed by medical staff, but the time that is prone to anal stenosis is mostly the recovery period after discharge. During this period, medical staff cannot intervene in manual anal dilation in time; manual anal dilation is fast and large in amplitude, and the anal pain and distension are severe, which can easily cause extreme tension and fear in patients. 3. Anal dilator with fixed size. Existing anal dilators are all rigid columnar anal dilators with fixed size. This type of anal dilator is composed of multiple anal dilators with different diameters. The initial suitable size of the anal dilator is selected according to the different degrees of anal canal stenosis. As the anus is gradually dilated, the diameter size is gradually increased to reach the required size, thereby achieving the purpose of anal dilation; but it is difficult and painful to insert, and large-scale movements are prone to cause additional damage. It is large and fixed, inconvenient to carry, and the diameter cannot be adjusted at will. This self-controlled adjustable anal dilator is equipped with a rubber airbag, a limit balloon, and cooperates with an injection tube and an injection seat. It can be inserted into the anus in a small size first, and liquid or gas is injected with a syringe. The rubber airbag and the limit balloon gradually expand slowly, and at the same time, the anus and anal canal are gradually stretched and expanded. The slow process allows the patient's anus to adapt, and the entire anal dilation process can be controlled by the patient himself, avoiding the patient's pain and tension, so that the patient can complete the anal dilation in a more comfortable process.

As the rubber air bag 8 is filled and expanded, the limiting balloon 9 is filled, expanded and shaped accordingly, so that the force-applying part is stretched outward to play an expansion role.

[0019] In this embodiment, one end of the airway tube is connected to the gas injection seat 1, and the other end is connected to the syringe, wherein a regulating valve is provided at the connection between the syringe and the airway tube, and the regulating valve can infuse liquid or gas into the inside of the airway tube when the syringe is injected. When the syringe is pulled out, the regulating valve is automatically closed to achieve the closure of the airway tube, thereby preventing the rubber airbag 8 from leaking. The liquid or gas discharged during injection enters the inside of the gas injection seat 1 along the airway tube and is discharged from the air outlet 7 on the air injection tube 6. The discharged liquid or gas can achieve the gradual expansion of the rubber airbag 8. After the rubber airbag 8 is expanded, it presents a columnar structure under the constraint of the limiting balloon 9. When the device is running, the air injection tube 6 with the rubber airbag 8 and the limiting balloon 9 is inserted into the inside of the anus, and the syringe infuses liquid or gas into the inside of the gas injection seat 1 through the airway tube to achieve the gradual expansion of the rubber airbag 8 and the limiting balloon 9, and the expansion size is controlled according to actual needs. Compared with the prior art, the present application has the following advantages: 1. The natural anal dilation of feces is short-lived and cannot reach the required anal dilation time, and the dilation force is not enough. Most patients need to combine other anal dilation methods. 2. Manual anal dilation is mostly performed by medical staff, but the time when anal stenosis is most likely to occur is the recovery period after discharge. During this period, medical staff cannot intervene in time with manual anal dilation; manual anal dilation is fast and has a large amplitude, and the anal pain and distension are severe, which can easily cause extreme tension and fear in patients. 3. Fixed-size anal dilator anal dilation. The existing anal dilators are all fixed-size rigid columnar anal dilators. This type of anal dilator is composed of a plurality of anal dilators of different diameters. The initial suitable size of the anal dilator is selected according to the different degrees of anal canal stenosis. As the anus is gradually dilated, the diameter size is gradually increased to reach the required size, thereby achieving an anal dilation purpose; but it is difficult and painful to insert, and large-scale movements are prone to cause additional damage. It is large and fixed, inconvenient to carry, and the diameter cannot be adjusted at will. This self-controlled adjustable anal dilator is provided with a rubber airbag 8 and a limiting balloon 9, and cooperates with an injection tube 6 and an injection seat 1. It can be inserted into the anus in a small size first, and liquid or gas is injected with a syringe.

[0025] The anal dilator, by providing a rubber airbag 8, a limiting balloon 9, in combination with an injection tube 6 and an injection seat 1, can be inserted into the anus in a small size first, and then the rubber airbag 8 and the limiting balloon 9 gradually expand as liquid or gas is injected, so that the anus and anal canal are also gradually stretched and expanded. The slow process can adapt the patient's anus and can continue to expand the anus. The entire anal expansion process can be controlled by the patient, avoiding the patient's pain and tension, so that the patient can complete the anal expansion in a more comfortable process. By providing an airway limiting groove 2, the airway can be limited to avoid entanglement of the pipeline, ensuring the smooth progress of the liquid or gas injection process, which is conducive to improving the stability of the device when in use.
