Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a balloon-type sterile protective sleeve. Background Technology

[0002] Transcavitary ultrasound is a commonly used ultrasound examination method in clinical practice, including transvaginal gynecological ultrasound and transrectal prostate ultrasound. It can effectively avoid the gas interference and other factors that affect image quality that are common during transabdominal examinations.

[0003] However, in practice, due to the nervousness of some patients or the lack of proficiency of the examiners, the friction between the probe and the cavity wall often increases, leading to pain and discomfort, and potentially even damage to the cavity mucosa. This is especially true when the probe is inserted directly. Furthermore, differences in operating habits among examiners make it difficult to standardize the procedure for transcavitary ultrasound examinations.

[0004] To reduce discomfort for patients and standardize transcavitary ultrasound examinations, the use of sterile protective covers and skin-friendly soft rubber materials has become a standard practice, but it is still difficult to reduce the discomfort caused by the probe to patients.

[0005] Therefore, there is an urgent need for a balloon-type sterile protective sleeve that can solve one or more of the above problems. Summary of the Invention

[0006] To address one or more problems existing in the prior art, the present invention provides a balloon-type sterile protective sleeve. The technical solution adopted by the present invention to solve the above problems is: a balloon-type sterile protective sleeve, comprising: an elastic valve, the elastic valve being provided with an insertion hole and an injection hole, the open end of the protective sleeve being sleeved and fixed to the outer surface of the elastic valve, the insertion hole and the injection hole communicating with the interior of the protective sleeve; The ultrasonic probe is inserted into the protective sleeve through the insertion hole, and the injection hole is used to inject acoustic conductive liquid into the protective sleeve; A balloon kit, wherein the balloon kit is provided with an annular hole, the elastic valve is inserted into the annular hole, the balloon kit is connected to the first end of a three-way connector through a pipeline, the second end of the three-way connector is connected to the inflation bladder through an adjusting valve, and the third end of the three-way connector is connected to the depressurization bladder through a control valve. The inflatable bladder is used to inflate the balloon assembly, the depressurization bladder is used to collect the gas discharged from the balloon assembly, and the regulating valve and the control valve are used to regulate the air flow and control the opening and closing.

[0007] In some embodiments, the inner wall of the insertion hole is provided with an elastic seal, which is used to seal the gap between the insertion hole and the ultrasonic probe.

[0008] Furthermore, the elastic seal is provided with a plurality of circumferentially arranged diaphragms.

[0009] In some embodiments, the opening end of the protective sleeve is provided with a tension ring, and the outer surface of the elastic valve is provided with a limiting groove, into which the tension ring is inserted.

[0010] In some embodiments, the outer surface of the resilient valve is provided with a limiting flange, which is used to limit the balloon assembly.

[0011] In some embodiments, the device further includes a plugging member for sealing the injection hole.

[0012] In some embodiments, a ring-shaped recess is formed on the outer surface of the balloon kit.

[0013] In some embodiments, the inflatable bladder is provided with a one-way inlet valve and a one-way outlet valve, the one-way outlet valve being connected to the regulating valve.

[0014] In some embodiments, the annular hole is a flared hole; the elastic valve is a circular rubber component.

[0015] The technical effects achieved by this invention are as follows: During transcavitary ultrasound examination, the inflatable and retractable balloon kit slowly expands the cavity opening to a suitable size, facilitating the slow insertion of the ultrasound probe and reducing discomfort for the patient. Fluid is injected into the protective sleeve through the injection port, causing it to expand and allowing for controlled-speed expansion of the cavity, facilitating further insertion of the ultrasound probe into the deeper parts of the cavity. During this process, the injected acoustic fluid promotes expansion, guides ultrasound, and provides cushioning, ultimately effectively reducing discomfort for the patient throughout the transcavitary ultrasound examination. Furthermore, the structure of this application is simple and convenient to assemble, use, and disassemble, enabling standardized and efficient operation of transcavitary ultrasound examinations.

Detailed Implementation

[0018] To make the above-mentioned objects, features, and advantages of the present invention more readily understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] This invention discloses a balloon-type sterile protective sleeve, combined with Figures 1-4 As shown, it includes: a resilient valve 1, the resilient valve 1 being provided with an insertion hole 10 and an injection hole 11, the open end of a protective sleeve 7 being sleeved and fixed on the outer surface of the resilient valve 1, the insertion hole 10 and the injection hole 11 being in communication with the interior of the protective sleeve 7; The ultrasonic probe 8 is inserted into the protective sleeve 7 through the insertion hole 10. The injection hole 11 is used to inject the acoustic conductive liquid 9 into the protective sleeve 7. After insertion, the probe body 80 of the ultrasonic probe 8 is located inside the protective sleeve 7. The balloon kit 3 is provided with an annular hole 30, the elastic valve 1 is installed in the annular hole 30, the balloon kit 3 is connected to the first end of the three-way connector 40 through the pipe 4, the second end of the three-way connector 40 is connected to the inflation bag 5 through the regulating valve 50, and the third end of the three-way connector 40 is connected to the depressurization bag 6 through the control valve 60. The inflatable bladder 5 is used to inflate the balloon assembly 3, the depressurization bladder 6 is used to collect the gas discharged from the balloon assembly 3, and the regulating valve 50 and the control valve 60 are used to regulate the air flow and control the opening and closing. The inflatable bladder 5 is equipped with a one-way air inlet valve and a one-way air outlet valve, and the one-way air outlet valve is connected to the regulating valve.

[0020] like Figure 2 As shown, it also includes: a sealing member 2, which is used to seal the injection hole 11. When needed, the sealing member 2 plugs the injection hole 11 to prevent the sound-conducting liquid 9 from flowing out directly.

[0021] It should be noted that the protective sleeve 7, the elastic valve 1, and the balloon assembly 3 are sterilized and individually packaged disposable items. The protective sleeve 7 can be a condom. They can be used with lubricant during use. Figure 2 , 3 As shown, the elastic valve 1 is a circular rubber part, and the balloon kit 3 is annular. To facilitate the insertion of the elastic valve 1 into the balloon kit 3, the annular hole 30 is a flared hole, and the side with the larger opening of the flared hole is the insertion port for inserting the elastic valve 1.

[0022] Specifically, in combination Figure 2 As shown, an elastic seal 100 is provided on the inner wall of the insertion hole 10, which is used to seal the gap between the insertion hole 10 and the ultrasonic probe 8. In some embodiments, the elastic seal 100 is provided with a plurality of circumferentially arranged diaphragms 101. The elastic seal 100 can be integrally formed inside the insertion hole 10 of the elastic valve 1. The elastic seal 100 ensures a tight connection between the inserted ultrasonic probe 8 and the elastic valve 1, preventing the injected acoustic fluid 9 from leaking out of the gap.

[0023] Specifically, in combination Figure 2 , Figure 4 As shown, the protective sleeve 7 has an elastic ring 70 at its open end, and the outer surface of the elastic valve 1 has a limiting groove 13. The elastic ring 70 is inserted into the limiting groove 13, thereby ensuring that the protective sleeve 7 is difficult to come out. The balloon kit 3 can press the protective sleeve 7 and part of the elastic ring 70 onto the outer surface of the elastic valve 1. Furthermore, a limiting flange 12 is provided on the outer surface of the elastic valve 1. The limiting flange 12 is used to limit the balloon assembly 3 and prevent the balloon assembly 3 from sliding out of the elastic valve 1.

[0024] Specifically, such as Figure 3 , Figure 4 As shown, the outer surface of the balloon kit 3 has a ring-shaped recess 31. When in use, the opening of the cavity is inserted into the recess 31, thereby preventing the balloon kit 3 from sliding directly out of the cavity opening or into the depth.

[0025] In use, the protective sleeve 7 and the elastic valve 1 are combined together. The protective sleeve 7 is guided through the balloon kit 3 using a medical guide rod. The balloon kit 3 is connected to the three-way connector 40 through the tube 4. The other two ends of the three-way connector 40 are also connected to the inflation bag 5 and the depressurization bag 6, respectively. The control valve 60 of the depressurization bag 6 is in the closed state. The medical guide rod passes through the insertion hole 10 and enters the protective sleeve 7. The medical guide rod is used to continue to insert the protective sleeve 7 into the cavity by about 5cm. The recess 31 of the balloon kit 3 is located near the cavity opening. Open the regulating valve 50 of the inflatable bladder 5, press the inflatable bladder 5 to inflate the balloon kit 3. During this process, pay attention to the inflation degree of the balloon kit 3, and control the air intake and air intake rate in a timely manner through the regulating valve 50. If the inflation is too high, the control valve 60 can be opened to connect the depressurization bladder 6 to depressurize until the inflation degree of the balloon kit 3 meets the requirements. Then stop inflating and depressurizing, and close the regulating valve 50 and the control valve 60. Remove the medical guide rod, insert the elastic valve 1 into the annular hole 30 of the balloon kit 3, and insert the ultrasound probe 8 into the protective sleeve 7 through the insertion hole 10. The ultrasound probe 8 is pre-inserted into the annular hole 30 of the balloon kit 3. Connect the injection tube or syringe to the injection hole 11 and then inject the sound-conducting liquid 9. During this process, depressurize in a timely manner through the depressurization balloon 6 to prevent abnormal expansion of the balloon kit 3. When the inner side of the balloon kit 3 slowly expands to the point where the ultrasound probe 8 can pass through, stop injecting the sound-conducting liquid 9. The ultrasonic probe 8 is pushed into the protective sleeve 7, and the ultrasonic probe 8 drives the protective sleeve 7 into the cavity until the inspection depth is reached. During this period, the acoustic fluid 9 is continuously injected. After the test is completed, the ultrasonic probe 8 is removed, and the sound-conducting liquid 9 inside the protective sleeve 7 is removed by opening the injection tube or using a syringe. During this process, the protective sleeve 7 slowly shrinks. Deflate the balloon kit 3 to gradually shrink it, disconnect the tubing 4 of the balloon kit 3 from the tee connector 40, remove the balloon kit 3, clean and disinfect the inflation bag 5 and the depressurization bag 6 and recycle them, clean other reusable equipment, and discard non-reusable equipment.

[0026] In summary, during transcavitary ultrasound examination, the expandable and contractible balloon kit slowly expands the cavity opening to a suitable size, facilitating the gradual insertion of the ultrasound probe and reducing patient discomfort. Fluid is injected into the protective sleeve through the injection port, causing it to expand and allowing for controlled-speed expansion of the cavity, facilitating further insertion of the ultrasound probe deeper into the cavity. The injected acoustic fluid promotes expansion, guides ultrasound, and provides cushioning, ultimately effectively reducing patient discomfort throughout the transcavitary ultrasound examination. Furthermore, the structure of this application is simple and convenient to assemble, use, and disassemble, facilitating standardized operation of transcavitary ultrasound examinations.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
