Description

Technical Field

[0001] The invention relates to the field of medical device products, in particular to a film sheath for a probe used for ultrasonic inspection and capable of preventing cross infection. Background Art

[0002] At present, hospitals or medical examination institutions use ultrasonic testing. When testing in vitro, the probe is mostly in direct contact with the skin. The operator may sterilize the ultrasonic probe before use to ensure hygiene. For some in vivo ultrasonic testing, such as gynecological examination, condoms are generally used for isolation and protection. Although it plays a role in preventing cross infection, because the material used is mostly rubber, its transmittance is about 84%, which will have a certain impact on the doctor's judgment.

[0003] TPU material is a kind of polymer material between rubber and plastic, and its name is thermoplastic polyurethane elastomer rubber. It is widely used in other fields, but it is used as a supporting auxiliary product for ultrasonic inspection equipment to prevent cross infection. At present, there is no such product. Summary of the invention

[0004] The purpose of the present invention is to provide a thin film sheath for ultrasonic inspection probe that can prevent cross infection. The thin film sheath is a disposable ultrasonic inspection protective sheath that is produced by secondary processing of a new environmentally friendly and degradable TPU material. The present invention solves the problem of cross infection caused by the exposed use of probes during ultrasonic inspection and the lack of protective measures between probes.

[0005] The technical solution of the present invention is: a thin film sheath for ultrasonic detection probe to prevent cross infection, including a TPU film sheath, and the thickness of the TPU film sheath is 2 to 8 threads. TPU material is difficult to form when the thickness is less than 2 threads, and the material is easily damaged if it is too thin. When the TPU material is less than 8 threads in thickness, its sound transmittance is ≥95%, which can completely not affect the doctor's judgment of the condition. Therefore, the optimal thickness size is 2 to 8 threads, that is, 0.02 to 0.08 mm, and the final size can be adjusted within this range according to the use requirements and processing requirements.

[0006] The TPU film cover includes a flexible cover body that is columnar when expanded. The TPU film cover is transparent and is layered or sheet-like as a whole when folded (refer to a fresh-keeping bag or a garbage bag).

[0007] At the same time, the flexible sleeve includes an open end and a closed end. When the TPU film sleeve is opened, the ultrasonic probe can be inserted into the flexible sleeve from the open end. The closed end is also the end surface of a TPU film, and the film surface needs to be relatively flat and uniform in texture. Because the film surface at the closed end is directly covered on the generating end of the ultrasonic probe, it is necessary to avoid problems such as reception interference or sleeve head damage as much as possible.

[0008] Furthermore, in order to increase the applicability of the TPU film sleeve and reduce the difficulty of the set, a thin wallpaper tube is padded at the closed end of the TPU film sleeve. At present, the thin wallpaper tube is required to have a slight hardness, generally 25~51g / m 2 The paper should be thick enough to support the TPU film cover. At the same time, it should not be too thick to damage the TPU film cover or affect the operation.

[0009] The thin wallpaper tube is deformed by opening or folding through the creases. The thin wallpaper tube can be bonded in the TPU film sleeve, or it can be horizontally supported in the TPU film sleeve according to the width size. Generally, the width of the thin wallpaper tube after folding is the same as the radial size of the flexible sleeve. This has a better fit, will not fall off or move, and has better operability.

[0010] For some special ultrasonic examinations, such as gynecological examinations, the shape of the corresponding ultrasonic probe is different due to the limitations of the operating area. According to such situations, a protruding front end portion is formed axially on the TPU film sleeve, which is also a columnar film body, and preferably extends in the axial direction of the flexible sleeve.

[0011] Correspondingly, the thin wallpaper tube is placed in the front end portion, and therefore, the closed end surface of the front end portion needs to be flat and uniform in texture.

[0012] The advantages of the present invention are: the structural body based on TPU material has reasonable shape arrangement and thickness requirements, and its sound transmittance is ≥95%, which does not affect the doctor's judgment on the condition at all. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0014] Figure 1 A schematic diagram of a preferred embodiment of the present invention;

[0015] Figure 2 A schematic diagram of another preferred embodiment of the present invention;

[0016] Wherein: 1. flexible sleeve; 2. thin wallpaper tube; 3. front end. DETAILED DESCRIPTION

[0017] Preferred embodiment 1 of the present invention:

[0018] TPU film sleeve, thickness is 2-8 threads. TPU material is difficult to form when the thickness is less than 2 threads, and the material will be easily damaged if it is too thin. When the TPU material is less than 8 threads, its sound transmittance is ≥95%, which will not affect the doctor's judgment of the condition at all.

[0019] The TPU film sleeve comprises a flexible sleeve body 1 which is in a columnar shape after being expanded, and the flexible sleeve body 1 comprises an open end 4 and a closed end, and the ultrasonic probe can be inserted into the flexible sleeve body from the open end. The closed end is an end surface of a TPU film, which directly contacts the generating end of the ultrasonic probe.

[0020] Preferred embodiment 2 of the present invention:

[0021] On the basis of Example 1, a thin wallpaper tube 2 is padded at the closed end of the TPU film sleeve. The thin wallpaper tube 2 is deformed by the creases to be stretched or folded. The TPU film sleeve can be stretched by squeezing the thin wallpaper tube 2 to facilitate the sleeve. At the same time, the thin wallpaper tube 2 can increase the tension on the surface of the front end of the TPU film sleeve to avoid wrinkles and overlap, which affects the test results. Moreover, the thin wallpaper tube 2 can increase the hardness of the front end of the TPU film sleeve, improve the stability of the TPU film sleeve stacked on the probe, and avoid the occurrence of rolling sleeves.

[0022] Preferred embodiment 3 of the present invention:

[0023] For some special ultrasonic examinations, such as gynecological examinations, the shape of the corresponding ultrasonic probe is different due to the limitation of the operating part. According to such a situation, a protruding front end portion 3 is formed on the TPU film sleeve along the axial direction, which is also a columnar film body, and preferably extends in the axial direction of the flexible sleeve.

[0024] Correspondingly, the thin wallpaper tube 2 is placed in the front end portion 3, so the closed end surface of the front end portion 3 needs to be flat and have a uniform texture.

[0025] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
