Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a handheld fixing sleeve for a B-ultrasound sound-transmitting membrane. Background Art

[0002] Medical ultrasound is a medical imaging diagnostic technology based on ultrasound, which allows the visualization of muscles and internal organs, including their size, structure and pathological lesions. Among them, intracavitary ultrasound refers to the examination performed by inserting a special ultrasound probe into certain cavities of the human body. Some organs and lesions are located deep in the human body. In order to avoid the influence of other tissues, intracavitary detection methods are adopted, which can make the detected organs appear more clearly, such as esophageal ultrasound examination and rectal ultrasound examination.

[0003] The probe is an important part of the ultrasound scanner. During use, the probe needs to be inserted into the patient's body and directly contact the patient's examination site through the coupling agent, so it needs to be cleaned and disinfected regularly. At present, the ultrasound probe is generally disinfected by water washing-enzyme solution-disinfectant-secondary water washing. However, the process of disinfecting the ultrasound probe is cumbersome, time-consuming and labor-intensive; and using disinfectants for disinfection every time will accelerate the aging of the probe. Summary of the invention

[0004] The utility model aims to solve the existing problems and provide a handheld fixing sleeve for B-ultrasound sound-transmitting membrane. In order to achieve the above purpose, the technical solution adopted by the utility model includes a probe protective sleeve for wrapping the probe, a cylinder body and an end cover; the front end of the probe protective sleeve is sealed, and a fixing ring is provided at the opening of the rear end; a central hole is provided in the middle of the cylinder body and the end cover for the probe to pass through; the inner edge of the central hole on the front end surface of the cylinder body is bent toward the rear end along the axis to form a flange; the shape of the end cover corresponds to the cylinder body, wherein the inner edge of the hole and the end of the flange are separated by a spacing for the probe protective sleeve to extend out; after the cylinder body and the end cover are butted, the inner wall of the side wall of the cylinder body, the outer wall of the flange and the inner wall of the end cover form an annular cavity for accommodating the probe protective sleeve.

[0005] The flange is parallel to the side wall and has the same length.

[0006] Wherein, a circular guide groove is formed by a smooth transition between the flange of the cylinder and the first end surface of the cylinder.

[0007] The cylinder is provided with a cylindrical hole protruding toward the end cover; the end cover is provided with a cylindrical seat for corresponding assembly with the cylindrical hole.

[0008] Among them, the inner edge of the hole in the end cover is provided with a guide eaves bent and extended toward one side of the cylinder body.

[0009] Wherein, the outer wall of the end cover is provided with a hand-holding ring or a hand-holding handle.

[0010] Compared with the prior art, the utility model isolates the ultrasonic probe from the outside world through the matched cylinder, end cover and probe protection cover, which can completely realize the aseptic operation of ultrasonic detection in the human cavity and avoid cross infection; there is no need to disinfect the ultrasonic probe, which slows down the aging of the probe; the wearing process is simple and smooth, and the operation is convenient, which reduces the labor of medical workers, shortens the operation time and improves work efficiency.

DETAILED DESCRIPTION

[0016] The utility model will now be further described with reference to the accompanying drawings.

[0017] See also Figures 1 to 3 , Figures 1 to 3 What is shown is an embodiment of the utility model, which mainly includes a probe protective cover, a barrel and an end cover. The probe protective cover is wrapped around the outer wall of the probe, and its front end is sealed to isolate the ultrasonic probe from the outside world. A fixing ring is provided at the opening at the rear end of the probe protective cover, and the fixing ring is used to be placed in the annular space formed by the barrel and the end cover.

[0018] The cross section of the cylinder and end cap is C-shaped, with a central hole for the probe to pass through. Figure 1 The inner edge of the middle hole on the front end of the cylinder is bent along the axis of the cylinder toward the other end to form a flange; the flange is a C-shaped arc, parallel to the side wall, the same length, and the two are concentrically arranged. A space for accommodating a fixed ring is sandwiched between the flange and the side wall of the cylinder, which constitutes the main part of the annular space.

[0019] See also Figure 2 and Figure 3The shape of the end cover corresponds to that of the cylinder, and its cross section is also circular, with a central hole in the middle. The inner wall of the front end face of the end cover is butted and spliced ​​with the flange and side wall of the cylinder, and the inner edge of the central hole of the end cover and the end of the flange are radially separated by a distance for the sleeve of the probe protective cover to extend. The inner wall of the side wall of the cylinder, the outer wall of the flange, and the inner wall of the front end face of the end cover form an annular cavity for accommodating the probe protective cover.

[0020] As a preference, see Figure 1 The inner edge of the cylinder flange and the outer wall of the cylinder smoothly transition to form a circular guide groove, which is conducive to the placement of the fixing ring and plays a role in protecting the probe protective cover.

[0021] As a preference, see Figure 1 and Figure 3 As the assembly structure of the cylinder and the end cover, the inner wall of the front end face of the cylinder (outside the side wall) is provided with a plurality of cylindrical holes protruding toward the end cover (rear); the front end face of the end cover is provided with a cylindrical seat for corresponding assembly with the cylindrical holes. After the cylindrical holes are inserted into the cylindrical seat, the overall structure can be locked; after use, it can be disassembled. The C-shaped notch of the cylinder and the end cover is used to manually remove the inserted fixing ring after disassembly.

[0022] As a preference, see Figure 3 The end of the cylindrical end cover is provided with a guide guard extending toward a side away from the front end surface of the cylindrical end cover. The guide guard is C-shaped and is located at the spacing through which the probe protective cover passes. Its arc transition shape can prevent the probe protective cover from being cut by the sharp part.

[0023] As a preference, see Figure 2 The outer wall of the end cover is provided with a hand-held ring or a hand-held handle for the user to operate. Figure 4 When in use, first place the fixing ring of the probe protective cover between the flange and the side wall of the cylinder, with the cover side of the probe protective cover extending toward the rear. Then assemble and close the end cover and the cylinder correspondingly through the cylindrical hole and the cylindrical seat structure. At this time, insert the probe from the rear end of the probe protective cover to complete the wrapping. This embodiment isolates the ultrasonic probe from the outside world through the matched cylinder, end cover and probe protective cover, which can completely realize the aseptic operation of ultrasonic detection in the human cavity and avoid cross infection; further, there is no need to disinfect the ultrasonic probe, which slows down the aging of the probe.

[0024] The above describes the implementation mode of the utility model in combination with the drawings and embodiments. The structure given in the embodiments does not constitute a limitation of the utility model. Those skilled in the art can make adjustments as needed. Various deformations or modifications within the scope of the attached claims are within the scope of protection.
