Description
Technical Field
The utility model belongs to the field of medical instruments, and particularly relates to a sterile isolation protective sleeve injected with a couplant through a body cavity ultrasonic probe.
Background
The ultrasonic diagnosis has the characteristics of high performance, multiple functions, high resolution, high definition and the like, so the ultrasonic diagnosis is widely applied in clinic. The ultrasonic probe can avoid lung qi, gastrointestinal qi and bone tissue through corresponding body cavity of human body, and approach to deep tissue to be probed, such as rectal probe for male prostate examination, vaginal ultrasonic probe for female visceral organ in pelvic cavity, especially for examination of uterus adnexal region; the transesophageal probe is used for detecting pathological changes of the esophageal mediastinum and the gastric cardia part and the like. In addition, ultrasound is widely used for interventional procedures, i.e., for diagnostic or therapeutic purposes by inserting or injecting a puncture needle, a drainage catheter or a drug into a lesion, a cavity, a body cavity, a duct or other specific part to be treated correctly under ultrasound guidance. When ultrasonic waves are incident on an interface of two different media (air and human soft tissue) in ultrasonic examination and diagnosis, the impedance difference between the two media is large, the reflection coefficient is large, and the sound energy which penetrates through the air interface and enters the other medium soft tissue is small. If the probe is in dry contact with the soft tissue of the human body, the emitted ultrasonic waves cannot reach and enter the soft tissue of the human body at all due to the strong reflection action of the thin air layer between the probe and the soft tissue of the human body, and the diagnosis or treatment effect cannot be achieved. Therefore, it is necessary to fill a space between the probe surface and the skin with a substance to expel air and form a channel for smooth and undistorted propagation of the ultrasonic waves.
The medical ultrasonic couplant as water polymer gel preparation has acoustic impedance similar to that of human soft tissue, and is medium filled and painted between skin and probe for transmitting sound wave in ultrasonic examination. Therefore, the filling of the couplant is closely related to the quality of the ultrasonic image, the ultrasonic energy is lost due to poor filling, the resolution is reduced, and the image is blurred. In addition, according to the requirements of national standards such as disinfection management method, hospital infection management method, medical institution disinfection technical standard and the like, the diagnosis and treatment instruments, appliances and articles contacting the complete skin mucosa are disinfected. In particular, the basic requirements of primary medical institution hospital infection management are definitely proposed: ultrasonic probes (ultrasonic examination of body cavities such as skin, mucous membrane or esophagus, vagina, rectum and the like) need to be used by one person with a disinfection or isolation membrane and the like. Therefore, in order to fill the coupling agent and avoid cross contamination in the ultrasonic probe through the body cavity, a sterile bag is used at the ultrasonic probe in actual operation. However, when the aseptic bag is used, the aseptic bag needs to be filled with medical coupling agent, and then the aseptic bag is coated with the ultrasonic probe for body cavity and inserted into the body cavity of a human body for ultrasonic examination. The sterile bags currently used have the following drawbacks: 1. the material is too thick, the acoustic impedance is greatly different from the human soft tissue, and the ultrasonic imaging quality is poor; 2. the aseptic bag is used for filling the coupling agent, so that bubbles or wrinkles are easily generated on the contact surface of the aseptic bag and the probe, and the image quality of ultrasonic inspection is influenced; 3. the whole diameter of the ultrasonic probe is increased due to the fact that the couplant is required to be filled in the aseptic bag, and discomfort is caused to a patient in the insertion process; 4. when the ultrasonic probe is inserted into a body cavity of a human body, the couplant in the sterile bag is extruded easily due to normal physiological reaction or tension of a patient, so that the couplant is not filled completely; 5. in the ultrasonic inspection process, the addition or reduction of the coupling agent cannot be carried out according to the actual inspection requirements; 6. the fixing process of the sterile bag and the ultrasonic probe is complicated, and the sterile condition is not suitable to be achieved; 7. part ultrasonic examination operation is complicated, and aseptic bag can't laminate with ultrasonic probe, influences the operation.
