Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a portable prepuce dilator. Background Art

[0002] The statements herein only provide background art related to the utility model and do not necessarily constitute prior art.

[0003] Currently, in the urology department for treating male prepuce orifice stenosis, the prepuce is usually dilated by using a prepuce dilator to open the prepuce. The current prepuce dilator opens the prepuce through two structures for opening the prepuce. For example, patent application CN113318331A discloses a prepuce dilator, which includes a plurality of valve bodies and an adjusting member. The ends of the valve bodies are hinged and fixed, and the free ends of the valve bodies are provided with insertion parts that can extend into the prepuce. The adjusting member acts on the valve bodies and generates a force that makes the insertion parts of at least two valve bodies move away from each other. The inventor found that in the above prepuce dilator, since the prepuce and the prepuce dilator are in contact at two positions, and the valve bodies are made of rigid materials such as plastic, the whole prepuce is unevenly stressed, and the dilator is relatively heavy, which generates a large downward force on the patient when the patient carries it with him. The above factors will all lead to an increase in the pain, bleeding and other phenomena during the patient's surgical treatment, and the patient's use comfort is poor. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a portable prepuce dilator, which improves the patient's use comfort through flexible dilation.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] In a first aspect, an embodiment of the utility model provides a portable prepuce dilator, which includes an annular airbag. An inflation interface is arranged on the annular airbag, and a plug is arranged at the inflation interface. An annular flexible layer is fixed on the outer ring surface of the annular airbag, and the outer ring surface of the flexible layer is an inner concave surface that is concave towards the inside.

An annular flexible layer is fixed on the outer ring surface of the annular airbag, and a plurality of protrusions arranged in an array are arranged on the outer ring surface of the flexible layer.

[0009] Optionally, the protrusions are hemispherical protrusions.

[0010] In a third aspect, an embodiment of the present utility model provides a portable prepuce dilator, which includes an annular airbag. The annular airbag is provided with an inflation interface, and a plug is arranged at the inflation interface. An annular flexible layer is fixed to the outer ring surface of the annular airbag. The outer ring surface of the flexible layer is a concave surface that is recessed inward, and a plurality of protrusions distributed in an array are arranged on the surface of the concave surface.

[0011] Optionally, the concave surface adopts a concave arc surface that is recessed inward.

[0012] Optionally, the protrusions adopt hemispherical protrusions.

[0013] Optionally, the flexible layer is made of medical silicone or natural rubber.

[0014] Optionally, a flexible connection part is arranged between the plug and the outer side surface of the annular airbag.

[0015] Optionally, the plug adopts a conical structure, the diameter of its small end is smaller than the diameter of the inflation interface, and the diameter of its large end is larger than the diameter of the inflation interface.

[0026] Embodiment 1

[0027] This embodiment provides a portable prepuce dilator, as Figure 1 - Figure 2 shown, including an annular airbag 1. The annular airbag 1 is provided with an inflation interface 2. The annular airbag 1 is inflated through the inflation interface 2. A plug 3 is arranged at the inflation interface 2 to block the inflation interface 2. The outer ring surface of the annular airbag 1 is provided with an annular flexible layer 4. The inner ring surface of the flexible layer 4 is adhesively fixed to the outer ring surface of the annular airbag 1. The outer ring surface of the flexible layer 4 is a concave surface 5 facing inward, that is, the outer ring surface of the flexible layer 4 is a concave surface 5 concave towards the center of the flexible layer 4. When in use, the annular airbag 1 is inflated, the flexible layer 4 contacts the prepuce, and the prepuce is clamped by using the concave surface. The annular airbag 1 supports the flexible layer 4 and drives the flexible layer 4 to expand the prepuce.

[0028] Specifically, the annular airbag 1 is made of polyethylene material. Polyethylene is a polymer material with good performance, having the characteristics of high strength, wear resistance, corrosion resistance, and resistance to chemical substance erosion. It can be understood that the annular airbag 1 can also be made of polyurethane or nylon materials, which have good squeezability.

[0029] The inflation interface 2 is arranged on the outer end surface of the annular airbag 1, and a plug 3 is arranged at the inflation interface 2. In order to ensure the sealing performance, the material of the plug is the same as that of the annular airbag. The plug adopts a conical structure. The diameter of the small end of the plug 3 is smaller than the diameter of the inflation interface, and the diameter of the large end is larger than the diameter of the inflation interface 2. The plug can be stuck at the inflation interface 2 to seal the inflation interface 2.

[0030] Further, in order to prevent the plug 3 from being lost, a flexible connecting part 6 is arranged between the plug 3 and the outer side surface of the annular airbag 1. The material of the flexible connecting part 6 is the same as that of the annular airbag. One end of the flexible connecting part 6 is connected to the plug, and the other end is fixed to the outer side surface of the annular airbag.

[0031] A flexible layer 4 is arranged on the outer ring surface of the annular airbag 1. The flexible layer 4 is made of medical silica gel or natural rubber. While being able to deform, it also has a certain hardness and can realize fixation with the prepuce.

[0032] In order to increase the fixing stability between the flexible layer 4 and the prepuce, the outer ring surface of the flexible layer 4 is an inner concave surface 5 that is concave towards the inside. After the prepuce is sleeved on the outer periphery of the flexible layer 4, the protrusions formed on both sides of the inner concave surface 5 can be used for limiting, preventing the entire dilator from falling off the prepuce.

[0033] Preferably, in order to increase the comfort of use, the inner concave surface 5 is an arc-shaped inner concave surface.

[0034] The using method of the prepuce dilator in this embodiment is as follows: the prepuce is sleeved on the outer periphery of the flexible layer 4. After the annular airbag 1 is inflated, the annular airbag 1 expands, thereby driving the flexible layer 4 to expand, and the flexible layer 4 expands the prepuce.

[0035] In the dilator of this embodiment, since the annular airbag 1 and the flexible layer 4 are annular flexible structures, the prepuce is uniformly stressed along the circumference, rather than being stressed at two points like a traditional prepuce dilator. Through the setting of the annular airbag and the flexible layer, flexible expansion is realized, and the weakest point of the narrow part can be automatically found, reducing treatment complications such as surgical bleeding and surgical pain, improving the comfort of use of patients. Moreover, the annular airbag 1 is an inflatable structure, and the flexible layer is supported by the inflatable structure to realize the expansion of the prepuce. Compared with traditional prepuce dilators, the weight of the entire dilator is greatly reduced, the comfort of use when the patient carries it with him is improved, and it is convenient to carry and use.
