Description

A protective device for an ultrasonic probe

technical field

The utility model relates to the technical field of ultrasonic testing equipment, in particular to a protection device for an ultrasonic probe.

Background technique

In recent years, ultrasonic exploration has become more and more widely used, especially in rescue and field environments. However, in the above cases, the environmental conditions are usually harsh, roads and fields are uneven, and the matching layer of the ultrasonic probe is easily damaged, and the matching layer of the probe is used as an ultrasonic probe. The important parts of the probe, once damaged, will seriously affect the normal detection of ultrasonic equipment. At the same time, in the process of using ultrasonic equipment, ultrasonic couplant is also essential. The main purposes of using ultrasonic couplants include: (1) filling the tiny gaps between the contact surfaces to prevent the trace air in these gaps from affecting the penetration effect of ultrasound; (2) through the "transition" effect of the couplant, the probe and the The acoustic impedance between the skin is reduced, thereby reducing the reflection loss of ultrasonic energy at this interface; (3) it plays a "lubricating" role, reducing the friction between the probe surface and the skin, so that the probe can slide flexibly for exploration.

Ultrasound detection as interventional therapy is a new discipline that has developed rapidly in recent years, integrating imaging diagnosis and clinical treatment. At the same time, through the guidance and monitoring of ultrasonic imaging equipment, puncture needles, catheters and other interventional equipment are used to enter the natural orifices or tiny wounds of the human body to introduce specific instruments into the diseased parts of the human body for minimally invasive treatment.

However, the ultrasonic testing equipment in the prior art, especially the ultrasonic probe, still has certain technical defects when used under the above-mentioned harsh environmental conditions, mainly including:

(1) At present, the ultrasonic probe does not have a special protective cover, and the user needs to be very careful when carrying it to protect the matching layer from vibration and other influences.

(2) Even if the palm ultrasonography or portable ultrasound needs to work normally, an additional bottle of couplant needs to be carried, which increases the burden, and the items are too fragmented. It is inconvenient to use, and on the other hand, it is easy to be forgotten on the spot.

(3) In rescue and field environments, when acute pericardial effusion and acute pleural and ascites are encountered, bedside ultrasound is often used to guide puncture, but during operation, there is a deviation between the angle of needle insertion and the sound beam angle of ultrasound, resulting in puncture failure It happens from time to time, and it largely depends on the technical level and experience of the doctor who performs the puncture. It needs to be repeated many times, which brings great pain to the patient. The existing ultrasonic probe puncture frame is inconvenient to disassemble, and the parts Fragments are not easy to carry in field or rescue environments.

Therefore, for the technical problem of how to protect the ultrasonic probe, avoid damage to the probe matching layer, and at the same time ensure the convenient use of the couplant and the precise operation of the puncture needle, no corresponding solution has been proposed so far.

Utility model content

In view of this, the present invention proposes a protective device for an ultrasonic probe, which is used to protect the ultrasonic probe, and can also accommodate a couplant and locate a puncture needle. Wherein, the protection device includes a shell that shields the ultrasonic probe, a couplant release structure and a puncture needle guide structure; one side wall of the shell is a hollow structure, the outer side of the side wall is provided with a couplant inlet and outlet, and the couplant inlet and outlet are connected to the side wall. The hollow structure is connected; the couplant release structure is arranged in the hollow structure of the side wall, and the couplant release structure is communicated with the couplant inlet and outlet through the couplant release channel; Guided positioning through holes.

The ultrasonic probe protection device of the utility model can protect the ultrasonic probe from vibration, drop and wear when it is used in a special field environment.

At the same time, a puncture needle guiding and positioning channel is provided to ensure that the puncture needle can be accurately positioned and fixed during the use of the puncture needle, thereby improving treatment accuracy and medical efficiency. The integrated ultrasonic probe protection device ensures the convenience of carrying and use.

In order to solve the above-mentioned technical problems, the utility model is realized through the following technical solutions, specifically:

Optionally, the housing of the protection device includes a top cover covering the top of the probe and a casing disposed outside the probe body, the top cover and the casing are correspondingly arranged together; the couplant release structure is arranged in the top cover.

Optionally, the top cover includes an inner bottom plate and an outer top plate, the edge of the inner bottom plate is connected to the edge of the outer top plate, a cavity for accommodating the couplant releasing device is formed between the bottom plate and the top plate, and the top plate is elastic, so that the couplant can be released by squeezing the top plate.

Further, the entire shell of the protection device can be made of elastic materials, such as silica gel materials with certain strength.

The matching design of the shell and the couplant release device highlights two important beneficial effects: on the one hand, the ultrasonic probe is covered by the shell structure, so as to avoid bumping and falling of the ultrasonic probe due to the lack of protection during the use of the ultrasonic probe in the field environment. The damage of the parts, especially the matching layer, affects the quality of ultrasonic scanning; on the other hand, the couplant release device is arranged in the protection device, which provides space for the storage of the couplant, and avoids forgetting to carry it during the process of transferring the environment and working place or missing couplant.

When ultrasound scans are performed in special environments in the field, if the couplant needs to be carried separately, it will be easily forgotten, or it will be lost when the environment is transferred. With the protection device of the present invention, because the cavity is opened and closed by the cover plate, the couplant can be filled into the protection device in advance, and the probe can be carried and protected, and at the same time, it can also avoid forgetting to carry the couplant for scanning.
