The embodiment provides a novel ultrasonic probe protective sleeve, as shown in fig. 1, the ultrasonic probe protective sleeve comprises a protective sleeve body 1, a couplant sac 2, a first catheter 3 and a second catheter 4; the protective sleeve body 1 is in a strip shape, one end of the protective sleeve body is an opening end, and the other end of the protective sleeve body is a closed end; the couplant bag 2 is connected in 1 open end of protective sheath body and is located outside the protective sheath body 1, first pipe 3 and second pipe 4 all have entry end and exit end, the entry end of first pipe 3 and second pipe 4 all with the couplant bag 2 is linked together, the 3 exit ends of first pipe are located the outside of protective sheath body 1, the exit end of second pipe 4 stretches into in the protective sheath body 1 and to the closed end extends.

The ultrasound probe protective sleeve of this embodiment may be a disposable, which may be folded and collapsed into a disposable degradable pouch package prior to use. When in use, the package is opened, and the ultrasonic probe protective sleeve is taken out and sleeved on the surface of the ultrasonic probe passing through the vagina or rectum; then, the couplant bag 2 is squeezed to enable the couplant in the couplant bag to flow out through the first catheter 3 and the second catheter 4 respectively, the couplant flowing out through the first catheter 3 flows to the outer surface of the protective sleeve body 1, the couplant flowing out through the second catheter 4 flows to the inner surface of the protective sleeve body 1, a medical worker with disposable gloves can rotate the protective sleeve body 1 to enable the couplant on the inner surface of the protective sleeve body 1 to be dispersed, and meanwhile the couplant on the outer surface of the protective sleeve body 1 is evenly smeared to all parts of the protective sleeve body 1.

After the ultrasonic probe protective sleeve is sleeved, a public couplant is not needed, only the couplant carried by the couplant bag 2 is used, so that the occurrence of cross infection is avoided, and the situation that the couplant slides to an examination bed, the clothes of medical staff or is infected with the vaginal wall of a patient is avoided without using the public couplant. And, all can the coating of protective sheath body 1 internal and external surface has the couplant, and then can get rid of the air between ultrasonic probe and the protective sheath body 1 and between protective sheath body 1 and vagina or the intestinal, can make the ultrasonic image more clear.

Example 2

The ultrasound probe protective sheath according to embodiment 1, as shown in fig. 1, the couplant balloon 2 comprises a first balloon 21 and a second balloon 22 which are isolated from each other by fluid, the first balloon 21 is in sealed communication with an inlet end of the first catheter 3, and the second balloon 22 is in sealed communication with an inlet end of the second catheter 4.

And then the couplants in the first catheter 3 and the second catheter 4 can be completely isolated and prevented from contacting with each other, so that the vagina or the intestinal tract is thoroughly prevented from contacting with the ultrasonic probe to cause infection, and the safety of ultrasonic detection is improved.

Example 3

According to the ultrasonic probe protective sleeve of embodiment 2, as shown in fig. 1, the first balloon 21 and the second balloon 22 are respectively opened with a first opening 9 and a second opening 10, and the first opening 9 and the second opening 10 are respectively detachably connected with a sealing cover.

If the doses of couplant stored in the first capsule body 21 and the second capsule body 22 are not enough to be used, the sealing covers on the first opening 9 and/or the second opening 10 can be opened, enough couplant is respectively filled into the first capsule body 21 and the second capsule body 22 through a disposable dropper or a syringe, then the sealing covers are covered, and normal use continues.

Example 4

According to the ultrasonic probe protective sleeve of embodiment 1, as shown in fig. 1 and 2, the first guide tube 3 and the second guide tube 4 are respectively provided with a check valve 5 for preventing liquid from flowing back to the couplant capsule 2, the check valve 5 includes a ring 53, a sealing sheet 51 and a connecting line 52, the ring 53 extends inward in a radial direction from the inner wall of the first guide tube 3 or the second guide tube 4, the outer diameter of the sealing sheet 51 is larger than the inner diameter of the ring 53 and smaller than the outer diameter of the ring 53, the sealing sheet 51 is located between the ring 53 and the outlet end, the connecting line 52 is multiple, and two ends of each connecting line 52 are respectively connected with the outer edge of the sealing sheet 51 and the ring 53.

When the ultrasonic probe protective sleeve of this embodiment is sleeved on an ultrasonic probe, the first capsule body 21 and the second capsule body 22 are squeezed to enable couplant in the first capsule body to flow to the first conduit 3 and the second conduit 4 respectively, the couplant can flow through a gap between the sealing sheet 51 and the inner wall of the conduit in the process that the couplant flows towards the outlet end of the conduit from the first conduit 3 or the second conduit 4, or the couplant can incline the sealing sheet 51 and then flow to the outlet end of the conduit rapidly, if the couplant flows reversely, the sealing sheet 51 can be gradually close to the ring body 53 under the pushing of the couplant and is covered on the ring body 53 to enable the couplant not to flow reversely to the inlet end of the conduit, so that the back flow of the couplant can be effectively prevented, and the outlet end of the first conduit 3 or the second conduit 4 can be kept to.

Example 5

The ultrasonic probe protection sleeve according to embodiment 1 is shown in fig. 1, wherein the first conduit 3 axially abuts against the outer surface of the protection sleeve body 1 in the length direction and extends, and the second conduit 4 axially abuts against the inner surface of the protection sleeve body 1 in the length direction and extends. First pipe 3 can be the flexible tube, and first pipe 3 can closely laminate protective sheath body 1 surface setting for ultrasonic probe protective sheath surface almost presents the smooth surface of easily inserting vagina or intestinal when using.

As another embodiment, the first conduit 3 may be axially attached to the inner surface of the protective sheath body 1 in the length direction and extend, but the outlet end of the first conduit 3 may be located outside the protective sheath body 1, specifically, the protective sheath body 1 may be provided with an opening for penetrating out of the outlet end of the first conduit 3, and the opening is hermetically connected to the tube wall of the first conduit 3, so that the couplant or the probe inside the protective sheath body 1 cannot contact the couplant, the vagina or the intestinal tract outside the protective sheath body 1 through the opening.
