The medical disinfection couplant is a couplant with a disinfection function, and is an existing commercially available product, so that the components of the medical disinfection couplant are not described in detail.

Eighth embodiment of the ultrasonic probe protective sheath:

as shown in fig. 5, since the width of thesubstrate 1 in the vertical direction is smaller in the present embodiment, the contact area with the outer side wall of thesubstrate 1 after the medical staff grips thesubstrate 1 is smaller, and the force is also transmitted to thesubstrate 1 during the process of applying the force to the sealing film and therubber sleeve 5 by theultrasonic probe 10 in the ejection direction Z, in order to make it easier for the medical staff to grip thesubstrate 1, the present embodiment is improved in that: the outer side wall of thesubstrate 1 is of a waist drum-shaped structure, wherein the diameter d1 of the middle position of the outer side wall is smaller than the diameter d2 of the two end positions of the outer side wall. Namely, thesubstrate 1 is of a circular ring structure, the middle position of thesubstrate 1 along the axial direction is radially inwards concave to form a waist drum-shaped structure with the diameter smaller than the diameters of the two end positions, and when each finger of a medical worker is gripped on the outer side wall of thesubstrate 1, the axial acting force can be more easily resisted when the finger is subjected to the axial acting force, so that thesubstrate 1 can be gripped more easily and conveniently.

The first embodiment of the protective sheath installer is as follows:

Of course, in this embodiment, after the medical staff holds the tail end of theultrasound probe 10 and inserts the front end of theultrasound probe 10 into the workingchamber 102, the medical staff needs to take out theultrasound probe 10 and the ultrasound probe protection sleeve sleeved on theultrasound probe 10 from the workingchamber 102 for use in the ultrasound examination, at this time, if the medical staff exits from the upper port along the direction opposite to the insertion direction, the ultrasound probe protection sleeve in the workingchamber 102 should not be constrained by the workingchamber 102 along the direction opposite to the insertion direction of theultrasound probe 10.

The second embodiment of the protective sheath mounting device:

based on the first embodiment of the protective sheath installer described above, there is a risk that therubber sheath 5 is displaced relative to theultrasound probe 10 or even comes off theultrasound probe 10 during the process of withdrawing theultrasound probe 10 from the upper port, and therefore the improvement of this embodiment lies in: the outer side wall of thebarrel 100 is provided with aside opening 104 which is communicated with the workingcavity 102 and extends to anupper port 103, and the width L of theside opening 104 is matched with the size of theultrasonic probe 10, so that theultrasonic probe 10 and the protective sleeve of the ultrasonic probe can be translated to the outside of thebarrel 100 through theside opening 104. That is, after theultrasonic probe 10 is inserted into the workingchamber 102 from theupper port 103 in the axial direction, theultrasonic probe 10 can be translated to the right in the horizontal direction as shown in fig. 15 so as to be translated out of thebarrel 100 after passing through theside port 104. The advantage of doing so is that can makerubber sleeve 5 and the better laminating of the front end ofultrasonic probe 10 whenultrasonic probe 10 along the continuousejecting rubber sleeve 5 in the ultrasonic probe protective sheath of direction of insertion, then medical personnel exert horizontal direction's effort can withultrasonic probe 10 along with ultrasonic probe protective sheath slip out from workingchamber 102, this horizontal direction's effort can not causerubber sleeve 5 along axial slip, for this reason make can keep good laminating effect between thisrubber sleeve 5 and theultrasonic probe 10, and for ultrasonic examination, it is the important factor that influences ultrasonic examination effect to laminate closely and the zero clearance cavity between ultrasonic probe and therubber sleeve 5.
