Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a mounting device for a detection head. Background Art

[0002] Currently, the cervical opening of pregnant women is checked manually by a finger. Because different doctors have different finger sizes, the test results vary. Furthermore, frequent prenatal checkups often result in a poor experience for pregnant women and increase pain and infection risks. Therefore, developing an accurate prenatal test instrument to replace manual finger examination has become a research direction in this field.

[0003] For example, Chinese patent number CN202211239837.2 discloses a prenatal testing instrument and system. The instrument, specifically a probe, can be used to replace fingertips to check for cervical dilation and other conditions. However, this prior art probe lacks a specific device for internal installation. Instead, the probe must be manually held and inserted into the birth canal. The placement of the probe also relies on the doctor's feel, resulting in low installation efficiency, a poor user experience for pregnant women, and inaccurate placement.

[0004] Therefore, those skilled in the art are committed to developing a mounting device for a probe head that can quickly and accurately mount a probe head inside a body. Summary of the Invention

[0005] In view of the above-mentioned defects of the prior art, the present invention discloses a mounting device for a probe head, and the technical problem to be solved is to provide a mounting device for a probe head that can quickly and accurately mount the probe head inside a body.

[0006] To achieve the above-mentioned purpose, the present invention provides an installation device for a probe head, comprising a handle for holding, one end of the handle being connected to an outer tube for supporting the probe head, and a movable inner tube being provided inside the outer tube and the handle; the other end of the handle being connected to a control member for controlling the movement of the inner tube, and the inner tube is in contact and sealed with the connector of the probe head.

[0007] Preferably, the front end of the inner tube contacts and seals the O-ring of the connector. That is, when the front end of the inner tube contacts the O-ring, the inner tube and the connector form a sealed connection, and only then can negative pressure be generated within the probe through the inner tube. When the front end of the inner tube separates from the O-ring, the negative pressure within the inner tube and the connector is no longer present, and the probe can then be left in the body and the mounting device removed.

[0008] Preferably, the rear end of the inner tube is threadedly connected to the control member, and the inner tube can move axially when the control member rotates.

[0009] Preferably, the control member is a knob with internal threads that mate with the threads of the inner tube; the inner tube is provided with a limiting block, and the handle is provided with a limiting rib that mates with the limiting block, and the limiting rib can limit the rotation of the inner tube. When the rotation of the inner tube is restricted, turning the knob allows the inner tube to move axially, thereby achieving contact or separation with the O-ring.

[0010] Preferably, a negative pressure connector is provided on the side of the knob away from the inner tube, which is used to connect to a negative pressure aspirator. The air inside the probe can be extracted through the negative pressure aspirator, and the probe is adsorbed on the inner wall of the vagina through the adsorption holes on it. At this time, turn the knob clockwise to drive the inner tube to move, separate the inner tube and the probe, and then pull out the mounting device.

[0011] Preferably, the handle includes a right shell, a left shell and a top shell that are clamped together, and the top shell is located on the top of the right shell and the left shell. The clamping structure is convenient for installation and disassembly.

[0012] Preferably, a clamping block is provided on the inner edge of the right shell, a nail column is provided on the inner side of the right shell near the edge, and an arc-shaped support frame and reinforcing ribs are provided on the inner side of the right shell, and the arc-shaped support frame is used to install and fix the outer tube.

[0013] Preferably, the inner edge of the left shell is provided with a slot that cooperates with the block, the inner side of the left shell near the edge is provided with a pin that cooperates with the nail column, and the inner side of the left shell is provided with an arc-shaped support frame corresponding to the right shell.

[0014] Preferably, a slot for mounting the top shell is provided at the top docking surface of the right shell and the left shell; a snap-fit hole is provided at the edge of the slot of the right shell and the left shell, and a snap joint matching the snap-fit hole is provided on the inner side of the top shell.

[0015] Preferably, the inner side of the top shell is provided with reinforcing ribs, and the top shell is provided with round holes for installing photo and video buttons.

[0016] The working principle of this installation device is:

[0017] The handle is used by the operator to hold the probe and supports the outer and inner tubes for ease of use. The outer tube supports the probe, and the inner tube achieves a seal when in contact with the probe connector. Once the inner tube and probe are sealed, the inner tube applies negative pressure to the probe, securing it within the birth canal. The connector can be separated by moving the inner tube, which is controlled by a control unit. Once separated, the negative pressure dissipates, allowing the probe to detach from the inner tube and the mounting device to be removed.

[0018] The beneficial effects of the present invention are:

[0019] This installation device provides a convenient handle and reliable force, while the outer tube provides stable support for the probe tip. Compared to direct finger handling, this reduces the risk of infection during operation. Furthermore, the outer tube's length can be pre-designed to ensure accurate placement. This installation device allows for quick and accurate insertion of the probe tip into the body, reducing the risk of infection. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, in the description of the present invention, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific manner. Therefore, they should not be construed as limiting the present invention. The terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figure 1 As shown, the present invention provides a mounting device for a probe head, including a handle 1 for holding, one end of the handle 1 is connected to an outer tube 2 for supporting the probe head 5, and a movable inner tube 3 is provided in the outer tube 2 and the handle 1; the other end of the handle 1 is connected to a control component for controlling the movement of the inner tube 3, and the inner tube 3 is in contact and sealed with the connector of the probe head 5.

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

[0031] The handle 1 is used by the operator to hold and supports the outer tube 2 and inner tube 3, making it convenient for the operator to use. The outer tube 2 supports the probe 5. The inner tube 3 and the connector of the probe 5 are in contact to achieve a sealing effect. After the inner tube 3 and the probe 5 are sealed together, the inner tube 3 applies negative pressure to the probe 5, securing the probe 5 within the birth canal. The connector between the inner tube 3 and the probe 5 can be separated by moving the inner tube 3. The movement of the inner tube 3 is controlled by the control unit. After separation, the negative pressure disappears, allowing the probe 5 to be separated from the inner tube 3, and the installation device can then be removed.

[0032] In the above embodiment, through the provision of this installation device, the handle 1 is convenient for the operator to use and provides reliable force, while the outer tube 2 stably supports the probe 5, thus reducing the risk of infection during operation compared to direct finger handling. Furthermore, the length of the outer tube 2 can be pre-designed to ensure accurate placement. Using this installation device, the probe 5 can be quickly and accurately installed within the body, reducing the risk of infection.

[0033] like Figure 2 and Figure 7As shown, the front end of the inner tube 3 is in contact and sealed 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. Only then can negative pressure be generated within the probe 5 through the inner tube 3. When the front end of the inner tube 3 separates from the O-ring 51, the negative pressure within the inner tube 3 and the connector is no longer present. The probe 5 can now remain within the body and the installation device can be removed. Simultaneously, the rear end of the inner tube 3 is threadedly connected to a control member, allowing the inner tube 3 to move axially when the control member is rotated. In this embodiment, the control member is a knob 4 with internal threads that threadably mate with the inner tube 3. A limiting block 31 is provided on the inner tube 3, and a limiting rib 116 is provided within the handle 1 to mate with the limiting block 31. The limiting rib 116 restricts the rotation of the inner tube 3. Specifically, the limiting rib 116 can be two ribs forming a limiting groove in each of the left and right shells as shown, or a single rib in each shell, but in opposite directions, to precisely limit the rotation of the inner tube 3. When the rotation of the inner tube 3 is restricted, the inner tube 3 can be moved axially by turning the knob 4, thereby achieving contact or separation with the O-ring 51. At the same time, a negative pressure connector 41 is provided on the side of the knob 4 away from the inner tube 3. The negative pressure connector 41 is used to connect to a negative pressure suction device, through which the air inside the probe 5 can be extracted, and the probe 5 is adsorbed on the inner wall of the vagina through the adsorption holes on it. At this time, turn the knob 4 clockwise to move the inner tube 3, separate the inner tube 3 and the probe 5, and then pull out the installation device.

[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 mutually clamped. The top shell 13 is located on the top of the right shell 11 and the left shell 12. The clamping structure is convenient for installation and disassembly. Figure 3 As shown, a block 111 is provided on the inner edge of the right shell 11, a nail column 112 is provided on the inner side of the right shell 11 near the edge, and an arc-shaped support frame 113 and a reinforcing rib 114 are provided on the inner side of the right shell 11. 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 matches the block 111, the inner side of the left shell 12 is provided with a nail 122 that matches the nail column 112 near the edge, and 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 surfaces of the right and left shells 11, 12 are provided with slots for mounting the top shell 13. The edges of the slots are provided with snap-fit holes 115, and the inside of the top shell 13 is provided with snap-fit joints 131 that mate with the snap-fit holes 115. Furthermore, the inside of the top shell 13 is provided with reinforcing ribs 114, and the top shell 13 is provided with circular holes 132 for mounting the camera and video buttons.
