Description

Disposable transesophageal ultrasonic probe sheath

Technical Field

The utility model relates to an improvement of a medical ultrasonic probe auxiliary appliance structure, in particular to a disposable transesophageal ultrasonic probe sheath, belonging to a medical auxiliary appliance.

Background

Transesophageal echocardiography is an examination method in which an ultrasound probe is placed in the esophagus or at a suitable position in the stomach, and the internal structure of the heart is observed from the back or below of the heart at a short distance. The examination approach is not shielded by the lung and the chest rib, the image is clearer, and some anatomical structures and subtle lesions which cannot be displayed by transthoracic ultrasound can be observed due to a special visual angle and higher resolution. As this technology matures and develops, more and more patients will receive transesophageal ultrasound examinations.

When the ultrasonic probe is subjected to ultrasonic examination by the esophagus, the ultrasonic probe needs to be contacted with body fluid of an examined person, so that thorough disinfection and safety protection of the ultrasonic probe are indispensable, the disinfection operation is complicated and time-consuming, and a plurality of factors can influence the effect of the ultrasonic probe. Through esophagus ultrasound as an invasive examination in contact with body fluid of a patient, if each patient uses a disposable sheath, the safety, sanitation, convenience and rapidness in operation of the examination can be ensured, the disinfection effect is exact, and the disposable sheath is more suitable for clinical application. However, the currently used imported or domestic disposable sheaths far from meeting the requirements exist in practical use: the sheath and the front end of the probe cannot be completely attached, so that the imaging effect is interfered; the middle section of the sheath is loose, so that the friction in the placing and moving process is increased, the probe is not convenient to move, and even the esophageal mucosa of a patient is injured; the ultrasonic probe is difficult to sleeve and withdraw the sheath, which wastes time and labor and is inconvenient to operate; high cost, poor use effect and the like.

Disclosure of Invention

The utility model aims at the aforesaid is not enough, provides a simple structure, with low costs, the formation of image is effectual, little, the flexible convenient disposable through esophagus ultrasonic probe sheath of use operation of patient's damage.

Realize the utility model discloses the technical scheme of purpose is: the disposable transesophageal ultrasonic probe sheath is composed of a cylindrical sheath body and an opening cover at one end of the sheath body, and is characterized in that the other end of the sheath body is fixedly connected with a probe sleeve matched with the shape of the esophageal ultrasonic probe, and one side of the probe sleeve is provided with a plane transparent detection window corresponding to an ultrasonic probe wafer; an elastic isolation ring is arranged between the probe sleeve and the sheath body; the end of the opening cover is provided with an insertion mark corresponding to the detection window; the opening cover is provided with a one-way valve which is communicated with a conduit extending into the probe sleeve and provided with an opening at the tail end; the connecting part of the outer part of the opening cover and the sheath main body is provided with an annular locking buckle.

The utility model is flexible and convenient to use and operate, and the couplant is injected at the detection window part of the probe sleeve or the ultrasonic probe wafer before detection; aligning the ultrasonic probe wafer to the insertion mark position of the end of the opening cover, inserting the ultrasonic probe wafer into the opening cover, and inserting the ultrasonic probe wafer into the detection window part of the probe sleeve to align the wafer of the ultrasonic probe to the detection window; then, the check valve is used for communicating negative pressure to pump out air in the sleeve through the guide pipe, so that the detection window is tightly compounded on the wafer of the ultrasonic probe, and simultaneously the air in the whole sleeve is pumped out to enable the main body of the sheath to be tightly wrapped on the pipe body of the ultrasonic probe, and the elastic isolation ring is firstly tightly hooped above the wafer by the elasticity of the elastic isolation ring in the pumping process to prevent the injected couplant from being excessively pumped out; after the redundant air in the jacket is sucked out, the locking buckle is closed to lock the jacket main body. Then the ultrasonic probe sleeved with the probe sheath is sent into the esophagus for ultrasonic cardiogram examination. After the ultrasonic inspection is finished, the probe sheath and the ultrasonic probe are pulled out from the esophagus together, the locking buckle is opened, the negative pressure disappears, and the probe sheath is gradually withdrawn from the ultrasonic probe tube body.

In order to improve the function of the catheter, besides the opening at the tail end of the catheter, at least one air suction hole can be formed in the wall of the catheter, so that the efficiency of sucking air in the whole sheath is improved, and the sheath body can be quickly and tightly wrapped on the tube body of the ultrasonic probe.

In order to be more convenient and faster to withdraw the sheath, a withdrawing and snapping hand along the axial direction of the opening cover can be pressed at the position where the opening cover is inserted with the mark, and an opening line embedded in the sheath body along the axial direction is fixedly connected to the withdrawing and snapping hand. After the sheath and the ultrasonic probe are pulled out of the esophagus together after the examination is finished, the negative pressure of the locking buckle is opened and disappears, the sheath is broken off by hands and pulled to be withdrawn from the breaking-off hands, and the sheath can be torn along the opening line by pulling downwards, so that the probe sheath is quickly withdrawn from the ultrasonic probe tube body.

The ultrasonic examination of the transesophageal tract is very convenient to operate, and the probe sheath can be quickly sleeved on the ultrasonic probe; the probe sleeve at the most front end of the probe sheath is matched with the wafer part at the front end of the ultrasonic probe in shape, so that the wafer of the ultrasonic probe can accurately correspond to the detection window which is transparent on the plane, and the wafer is tightly attached to the detection window through negative pressure suction, thereby obviously improving the imaging quality of ultrasonic inspection; the probe sleeve is tightly coated on the tube body, so that the probe sleeve is convenient to place and move, and a patient does not feel uncomfortable; the design of withdrawing the hand and the opening line can facilitate the operation of a single inspector and quickly take down the probe sleeve; the probe sheath is sterilized and is disposable, so that the direct contact between the ultrasonic probe and the body cavity of a patient can be effectively avoided, and the possibility of infection of viruses and germs is avoided; the ultrasonic probe can be effectively protected, the abrasion of the ultrasonic probe is prevented, and the service life of the ultrasonic probe is prolonged.
