DETAILED DESCRIPTION

[0028] The present application will be further described below in conjunction with the drawings and embodiments, and it should be noted that in the description of the present application, the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular way, and therefore cannot be understood as limiting the present application. The terms "first", "second", "third" and the like are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0029] As Figure 1 shown, the utility model provides a kind of installation device of probe head, including handle 1 for holding, one end of handle 1 is connected with the outer tube 2 for supporting probe head 5, outer tube 2 and handle 1 are equipped with movable inner tube 3;The other end of handle 1 is connected with the control member for controlling the movement of inner tube 3, and the connecting head of inner tube 3 and probe head 5 contact seal.

[0030] The working principle of the installation device is:

[0031] Handle 1 is used for operator to hold, and is used for supporting outer tube 2 and inner tube 3, to facilitate operator to use.External tube 2 is used for supporting probe head 5, and the connecting head of inner tube 3 and probe head 5 contact to achieve sealing effect.After the sealing connection of inner tube 3 and probe head 5, inner tube 3 will input negative pressure into probe head 5, so that probe head 5 is fixed inside birth canal.The connecting head of inner tube 3 and probe head 5 can be separated by the movement of inner tube 3, and the movement of inner tube 3 is controlled by control member, and after separation, negative pressure disappears, so that probe head 5 can be separated from inner tube 3, and then the installation device can be taken out.

[0032] In the above embodiment, by the setting of the installation device, handle 1 is convenient for operator to use and reliable in stress, and outer tube 2 can stably support probe head 5, compared with directly taking artificial finger, to avoid infection risk in operation.At the same time, the length of outer tube 2 can be designed in advance, to ensure the accuracy of placement position.Using the installation device, probe head 5 can be quickly and accurately installed into body, to reduce infection risk.

[0033] As Figure 2 and Figure 7As shown, the front end of the inner tube 3 contacts and seals with the O-ring 51 of the connector. That is, when the front end of the inner tube 3 contacts the O-ring 51, the inner tube 3 and the connector form a sealed connection, allowing negative pressure to be created inside the probe head 5 through the inner tube 3. When the front end of the inner tube 3 separates from the O-ring 51, there is no longer negative pressure inside the inner tube 3 and the connector, allowing the probe head 5 to remain inside the device before removing it. Simultaneously, the rear end of the inner tube 3 is threadedly connected to the control component, allowing the inner tube 3 to move axially when the control component rotates. In this embodiment, the control component is a knob 4 with internal threads, which engage with the inner tube 3. The inner tube 3 has a limiting block 31, and the handle 1 has a limiting rib 116 that engages with the limiting block 31, restricting the rotation of the inner tube 3. Specifically, the limiting rib 116 can be two ribs forming limiting grooves on the left and right shells as shown in the figure, or it can be one rib on each shell, but in opposite directions, effectively restricting the rotation of the inner tube 3. With the rotation of the inner tube 3 restricted, turning the knob 4 allows the inner tube 3 to move axially, thus enabling it to contact or separate from the O-ring 51. Simultaneously, a negative pressure connector 41 is located on the side of the knob 4 furthest from the inner tube 3. This connector 41 connects to a negative pressure suction device, which extracts air from the probe head 5, allowing the probe head 5 to adhere to the vaginal wall through its suction holes. Turning the knob 4 clockwise at this point moves the inner tube 3, disengaging it from the probe head 5. Once disengaged, the installation device can be pulled out.

[0034] like Figures 3 to 6 As shown, the handle 1 includes a right shell 11, a left shell 12, and a top shell 13 that are interlocked. The top shell 13 is located on top of the right shell 11 and the left shell 12. The interlocking structure facilitates installation and disassembly. Specifically, as... Figure 3 As shown, the inner edge of the right shell 11 is provided with a locking block 111, and the inner side of the right shell 11 near the edge is provided with a nail post 112. The inner side of the right shell 11 is provided with an arc-shaped support frame 113 and a reinforcing rib 114. The arc-shaped support frame 113 is used to install and fix the outer tube 2. Figure 4 As shown, the inner edge of the left shell 12 is provided with a slot 121 that mates with the locking block 111, and the inner side of the left shell 12 near the edge is provided with a locking pin 122 that mates with the pin post 112. The inner side of the left shell 12 is provided with an arc-shaped support frame 113 corresponding to the right shell 11. Figure 5 As shown, the top mating surfaces of the right shell 11 and the left shell 12 have slots for mounting the top shell 13; the edges of the slots in the right shell 11 and the left shell 12 have snap-fit ​​holes 115, and the inner side of the top shell 13 has snap-fit ​​connectors 131 that mate with the snap-fit ​​holes 115. In addition, the inner side of the top shell 13 has reinforcing ribs 114, and the top shell 13 has round holes 132 for mounting camera and video recording buttons.
