Description

Technical Field

[0001] The utility model belongs to the technical field of anal dilators, and particularly relates to an autonomously adjustable anal dilator component. 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 squeezed 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, anorectal surgery patients 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 afraid.

[0003] Currently, there are several methods for anal dilation: 1. Natural anal dilation: it is to use the discharge of formed stool to dilate the anus; natural anal dilation is achieved by one's own defecation, but the maintenance time is short and the required anal dilation time cannot be achieved. Most patients need to combine other anal dilation methods to prevent anal stenosis; 2. Manual anal dilation: generally, medical personnel insert fingers into the anal canal to dilate the anus back and forth, or put 2-3 fingers into the anus for a certain time to achieve the purpose of anal dilation; natural anal dilation is achieved by one's own defecation, but the maintenance time is short and the required anal dilation time cannot be achieved. Most patients need to combine other anal dilation methods to prevent anal stenosis; 3. Anal dilation with an anal dilator: generally, a slightly blunt, cylindrical and hard anal dilator with a slightly blunt head is placed in the anus to dilate the anus and maintain it for a certain time to achieve the purpose of anal dilation. This anal dilator has multiple sizes. According to different people and the degree of anal canal stenosis, the initial suitable anal dilator is selected, and the diameter is gradually increased to reach the required size, thereby achieving a normal anal canal circumference; this anal dilator is difficult and painful to insert, and large-scale movement is likely to cause additional damage. It is large and fixed, inconvenient to carry, and the diameter cannot be adjusted at will;

[0004] At present, there is also an air-bag anal dilator, which is generally filled with water to make the air bag expand continuously to achieve anal dilation. This air-bag anal dilator is generally connected to a medical syringe, through which the syringe injects water into the inside, and multiple injections are performed at intervals to achieve a normal anal canal circumference; however, there are differences between different individuals, and excessive water injection often causes discomfort. How to achieve autonomous adjustment is the problem we want to solve. Utility Model Content

[0005] The utility model provides an autonomously adjustable anal dilator assembly, which can solve the problems pointed out in the background technology.

[0006] An autonomously adjustable anal dilator assembly comprises an anal dilator, wherein a connecting end of the anal dilator is connected to one end of a main connecting pipe, a reversing valve and a flow control valve are sequentially arranged on the main connecting pipe according to the flow direction, the reversing valve is connected to one end of a bypass pipe arranged in parallel, and the other end of the bypass pipe is connected to the main connecting pipe, and the connection point is located behind the flow control valve.

[0007] Preferably, the flow control valve is a one-way control valve.

[0008] Preferably, the anal dilator is an air bag type anal dilator.

[0009] Preferably, a flow stop clamp is provided on the connecting tube of the anal dilator.

[0010] Beneficial effects: The utility model provides an autonomously adjustable anal dilator assembly, which can be autonomously adjustable, improve applicability and comfort, and the patient can operate it by himself according to his feeling and adjust it as needed, which can greatly reduce the patient's discomfort and improve the product's performance.

[0014] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0015] Example: Figure 1 As shown, an autonomously adjustable anal dilator assembly includes an anal dilator 1, which is specifically an airbag anal dilator. The connecting end of the anal dilator 1 is connected to one end of a main connecting pipe 2. The main connecting pipe 2 has two connecting ends, both of which can be connected in a plug-in manner, one end is plug-connected to the connecting pipe of the anal dilator 1, and the other end can be plug-connected to the liquid outlet end of a medical syringe 7. A reversing valve 3 and a flow control valve 4 are provided on the main connecting pipe 2 in sequence according to the flow direction. The flow control valve 4 can be a one-way control valve. The reversing valve 3 is connected to one end of a bypass pipe 5 arranged in parallel, and the other end of the bypass pipe 5 is connected to the main connecting pipe 2, and the connection point is located behind the flow control valve 4. The reversing switch is realized by the reversing valve 3 to meet the actual operation needs.

[0016] A flow-stop clamp 6 is provided on the connecting tube of some of the anal dilators 1. The flow-stop clamp 6 plays a role in maintaining pressure and stopping flow and is generally used as a backup.

[0017] The working principle or operation method of the utility model: according to Figure 1 Connect all components as shown, switch the reversing valve 3 to the direction of the flow control valve 4, slowly inject liquid through the medical syringe 7, and the liquid continuously enters the airbag anal dilator after passing through the flow control valve 4, so that the airbag anal dilator continues to expand. If the patient feels uncomfortable or too much liquid is injected during the process, switch the reversing valve 3 to the direction of the bypass pipe 5. At this time, the liquid in the airbag anal dilator will flow in the opposite direction under the action of pressure and flow back to the medical syringe 7 through the bypass pipe 5. The patient feels that the discomfort is alleviated or disappears, and switch the reversing valve 3 to the direction of the flow control valve 4 again, maintain the pressure for a period of time to dilate the anus, inject liquid again, repeat the above operation, and dilate the anus multiple times at intervals to achieve a normal anal canal circumference.

[0018] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
