[0021] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0022] Example 1:

[0023] A cervical sampler with a protective film, such as Figure 1 , Figure 2 It includes a sampling handle 1, a sampling brush head 7, a protective film 2, and a protective film control assembly.

[0024] like Figure 2 , Figure 3 The sampling brush head 7 is located at the end of the sampling handle 1. The sampling brush head 7 can be consistent with the shape of a traditional cervical sampler, with the bristles gradually shortening from the middle to both sides.

[0025] The sampling handle 1 is provided with a receiving cavity 11, which extends to the shortest end of the sampling brush head 7, and the farthest end of the receiving cavity 11, that is, the end closest to the sampling brush head 7, has an opening.

[0026] The protective film control assembly includes a control wire 5, which is disposed in the receiving cavity 11 and connected to the center of the protective film 2. A sealing body 6 is disposed in the receiving cavity 11. The sealing body 6 is generally made of rubber or silicone sealing ring. The control wire 5 passes through the sealing body 6 and is press-fitted with the sealing body 6 to achieve a sealing effect.

[0027] The protective film 2 is a flexible film, which can be selected as a thermoplastic polyurethane film, PU film or other polymer medical film. When the protective film 2 is unfolded, it is preferably circular, and elastic ribs 21, such as rubber bands, can be provided at the edges.

[0028] When the protective film 2 is in the protective state, it covers the outside of the sampling brush head 7. In the sampling state, as... Figure 4 The protective film 2 is pulled into the receiving cavity 11 using the control wire 5.

[0029] A protective film positioning body 14 is provided on the sampling handle 1. When the protective film 2 covers the outside of the sampling brush head 7, the rib 21 cooperates with the protective film positioning body 14 to prevent it from falling off. In this embodiment, as shown... Figure 3 The protective film positioning body 14 is a positioning ring. The end face of the positioning ring away from the sampling brush head 7 is provided with a groove to accommodate the rib 21. When the center position of the protective film 2 is pulled by the control wire 5, the rib 21 falls out of the groove.

[0030] In other embodiments, the protective film positioning body 14 is an annular groove provided on the outer circle of the sampling handle 1, and the rib 21 achieves the positioning effect by being installed in the annular groove.

[0031] The protective film control assembly also includes a control element 3 mounted on the sampling handle 1. The control element 3 is connected to the control wire 5 and is used to control the control wire 5.

[0032] like Figure 2 The control component includes a slider 31, which is installed in a groove on the sampling handle 1 and can slide along the sampling handle 1. The control wire 5 is connected to the slider 31. After the sampling brush head 7 is in place, the protective film 2 is pulled into the receiving cavity 11 by moving the slider 31 towards the proximal end (hand-held operation end) of the sampling handle 1, at which time rotation sampling can be performed.

[0033] Example 2:

[0034] Unlike in Example 1, in this example, as Figure 5 The control component includes a rotary body 32 in the form of a knob, which is rotatably mounted on the sampling handle 1. The control wire 5 is wound around the rotary body 32, and the control wire 5 can be retracted by rotating the rotary body 32.

[0035] Preferably, a transparent area 12 is provided on the sampling handle 1. After the sampler is in place, before sampling, the protective film 2 is pulled into the receiving cavity 11 and then pulled to the position of the transparent area 12. The transparent area 12 is located on the side near the proximal end of the sampling handle 1. By observing the position of the protective film 2, it is ensured that the protective film 2 has been detached from the sampling brush head 7 before rotating sampling.

[0036] Example 3:

[0037] Based on Embodiment 1 or 2, the protective film control assembly further includes a locking mechanism 4, which is connected to the control component and used to lock the control component, preventing it from operating. Figure 1 The locking mechanism 4 can be a buckle body connected to the control component. It is locked by buckling onto the sampling handle 1. Before sampling is required, the buckle body is opened so that the control component can move or rotate, thereby controlling the control wire 5.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
