Description

Ultrasound Probe Sterile Protective Cover

technical field

The utility model belongs to the field of devices for ultrasonic diagnosis, in particular to a sterile protective cover for an ultrasonic probe.

Background technique

Ultrasound is a sound wave with a frequency higher than 20,000 Hz. It has good directionality and strong penetrating ability. It is easy to obtain concentrated sound energy and has a long distance in water. It can be used for distance measurement, speed measurement, cleaning, welding, and stone breaking. , Sterilization, etc. There are many applications in medicine, military, industry, and agriculture.

Ultrasonic diagnostic instrument has the characteristics of high performance, multi-function, high resolution and high definition; the basic components include five components including transmitting, scanning, receiving, signal processing and display, which are divided into two major parts, namely the main unit and the probe . The probe is a traditional Chinese medicine connecting device between the main body and the ultrasonic diagnostic instrument.

Ultrasonic diagnostic instruments are widely used clinically. Ultrasonic probes are used repeatedly. Due to the high price of ultrasonic probes, the requirement of one probe per person cannot be met. In order to avoid cross-contamination, the usual operation is to repeatedly disinfect the ultrasonic probe, or use it without using it at the ultrasonic probe. Fungus bag. Repeated disinfection can easily cause the ultrasonic probe to be corroded and damaged by the disinfectant; while using a sterile bag, you need to apply a medical coupling agent before use, and the sterile bag is likely to generate air bubbles on the contact surface with the probe, which will affect the image quality of the ultrasonic examination. The process of fixing the bag and the ultrasonic probe is cumbersome, and it is not suitable to achieve sterile conditions. Therefore, during anesthesia invasive operations, such as: deep vein puncture catheterization and ultrasound-guided nerve block, etc., the process is difficult to meet the aseptic requirements, and in order to ensure sterility, the operation process is complicated, and the imaging quality is affected by air bubbles, which leads to poor imaging quality. unstable.

Utility model content

The silicone head is filled with ultrasonic coupling agent; the coupling agent is a water-soluble polymer colloid, which is used to exclude the air between the probe and the measured object, so that the ultrasonic wave can effectively penetrate the measured object to achieve effective detection purposes . The end of the fixed part is an open end, and the connection between the silicone head and the connecting part is provided with a first elastic band; the open end of the fixed part is set on the rod of the ultrasonic probe, and the first elastic band sets the silicone head on the ultrasonic probe. Probe head and fixed. The tail of the fixed part is provided with a second elastic band, the elastic elongation of the first elastic band is less than the elastic elongation of the second elastic band; the second elastic band fixes the fixed part to the rod of the ultrasonic probe, and the second elastic band The elastic elongation of the elastic elongation is greater than that of the first elastic belt, because the second elastic belt acts as the fixing part for fixing the protective cover body, while the first elastic belt only plays the role of preliminary fixing. , the ultrasonic probe is inserted into the silicone head through the fixing part and the connecting part, therefore, the elastic elongation of the first elastic band does not need to be very large.

The working principle and beneficial effects of the utility model are as follows: the ultrasonic probe passes through the fixed part and the connecting part of the protective cover body, and the head of the ultrasonic probe is inserted into the silicone head, the head of the ultrasonic probe can be coated with coupling agent, and the silicone head The part is coated with coupling agent so that no air bubbles intervene between the detection body and the ultrasonic probe; the second elastic band fixes the fixed part to the rod of the ultrasonic probe, and the first elastic band fixes the silicone head to the tail of the ultrasonic probe. Since the protective sheath body is sterile and disposable, it can ensure sterility. When using it, it is only necessary to put the protective sheath body on the ultrasonic probe. The silicone head of the protective cover body can be detected by coating the coupling agent. The operation is simple, and there is no need to sterilize the ultrasonic probe every time. The operation is simple and the sterility is guaranteed. The gel ensures no bubbles, and the surface between the silicone head and the ultrasonic probe head and between the silicone head and the collective is relatively smooth, so only a small amount of coupling agent needs to be applied, so the imaging quality is guaranteed and the imaging quality is stable.

Further, the outer and inner walls of the silicone head, the connecting part and the fixing part are all provided with protective films. The protective film can be touched by hand during the sleeve setting. After the sleeve is completed, the protective film can be torn off to ensure sterility.

Further, the silicone head has a width of 7-8 cm and a thickness of 2-3 cm. The usual ultrasonic probe is 7.5cm wide and 2cm thick. The width and thickness of the silicone head are comparable to the head size of the ultrasonic probe. If the gap is too large, it needs to be filled with a large amount of couplant.

Further, the fixing part is provided with fastening pieces on the outside. The fastening piece can strengthen the fixing effect of the fixing part.

Further, the protective film is a tearable plastic film. Tearable plastic film, low cost and stable quality, easy to process.

Further, the silicone head has a width of 7 cm and a thickness of 2 cm. The size is basically the same as that of the existing ultrasonic probe, relying on the elastic sleeve of the silicone itself, so as to ensure that the gap between the silicone head and the ultrasonic probe is small enough and the protective cover body can be set outside the ultrasonic probe.

Further, the fastening piece includes an elastic protrusion and an elastic groove matched with the elastic protrusion, the elastic groove and the elastic protrusion are connected to the outer wall of the fixing part, and the elastic groove is opposite to the elastic protrusion. The elastic connection is realized by the cooperation of the elastic protrusion and the elastic groove, so that the fixing part of the protective cover body is fixed more firmly.
