Technical Field

[0001] The utility model relates to the technical field of cervical sampling, in particular to a side-push type cervical sampler with a sampling head storage and pollution prevention function. Background Art

[0002] The side-push cervical sampler is a device used to collect cervical cell samples from women. The collected samples are used to diagnose diseases. It can collect samples quickly and conveniently, and significantly improve the collection quality of cervical exfoliated cells.

[0003] The cervical collector mainly uses a flexible material sampling head to push deep into the channel of the cervix from the side, so that the brush on the sampling head can contact the external cervix. The sampling head is then rotated in the same direction for five weeks, and finally taken out and placed in a special preservation bottle. When the sampling head is placed in the preservation bottle, it needs to be broken to facilitate placement in the preservation bottle. However, the sampling head is easily contaminated during the breaking process, making the sample on the sampling head inaccurate in subsequent testing. In addition, there is a possibility of contaminating the hands when the sampling head is cut off by direct contact, and the hygiene of the sampling cannot be guaranteed.

[0004] In view of the above problems, an innovative design was carried out based on the original side-push cervical sampler. Utility Model Content

[0005] The utility model aims to provide a side-push cervical sampler with a sampling head storage and anti-pollution function. The device is used to work, thereby solving the problem that the existing cervical sampler requires medical staff to easily touch the sampling area and contaminate the sample when cutting off the swab.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a side-push type cervical sampler with a sampling head storage and anti-pollution function, comprising a protective tube, a disposable sampling rod for sampling is arranged inside the protective tube, and a rotating assembly for rotation is installed at one end of the disposable sampling rod, and pushing assemblies are arranged on both sides of the rotating assembly, and a separation assembly is arranged inside the protective tube;

[0007] The separation assembly comprises a connecting rod which is slidably connected to the outside of the protective cylinder, a blade is connected to one end of the connecting rod, and a button is connected to the other end of the connecting rod.

[0008] Furthermore, movement grooves are provided on both sides of the protective tube, and the inner diameter of the protective tube is larger than the diameter of the rotating component.

[0009] The rotating assembly includes a mounting rod installed at one end of the disposable sampling rod, and a fixing ring is movably connected to the outside of the mounting rod through a bearing, a knob is connected to the other end of the mounting rod, and the total length of the mounting rod and the disposable sampling rod is greater than the length of the protective tube.

[0010] The pushing component includes an extrusion plate hinged on the outside of the fixing ring, and a pushing block is connected to the outside of the extrusion plate. A spring 1 is connected to the extrusion plate and the outside of the fixing ring. Two groups of the pushing component are symmetrically distributed on the outside of the fixing ring.

[0011] The pushing block corresponds to the position of the moving groove, and the spring 1 squeezes the plate in an inclined shape to push the pushing block through the moving groove in an initial state, and the width of the pushing block is consistent with the width of the moving groove.

[0012] The disposable sampling rod is composed of a sampling head and a sampling rod, and a cut-off point is arranged on the sampling rod near the sampling head, and the sampling head is made of flexible material.

[0013] When the push block moves to the end of the moving slot, the blade is aligned with the truncation point on the disposable sampling rod, and two groups of separation components are arranged on the side of the truncation point.

[0014] The button is arranged outside the protective tube, and a silicone material is arranged at the front end of the protective tube, and a second spring is connected between the outside of the protective tube and the button.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The utility model proposes a side-push type cervical sampler with sampling head storage and anti-pollution function. The existing cervical sampler requires medical staff to cut off the swab and easily touch the sampling area to contaminate the sample; while the utility model uses a button, a connecting rod, a blade and a spring. After the disposable sampling rod is collected, the protective tube is slowly taken out of the cervix as a whole, the pushing block is moved to the end of the moving groove, and the preservation bottle is taken out. The sampling brush at the front end of the disposable sampling rod is put into the preservation bottle. In order to avoid direct contact with the disposable sampling rod and contamination of the disposable sampling rod after sampling, the buttons on both sides of the protective tube can be pressed inwards. As the pushing block moves When it reaches the very end, the cutoff point on the disposable sampling rod is aligned with the blade position. At this time, the button moves inward to push the connecting rod inward, and the spring 2 between the button and the outer wall of the protective tube is squeezed, which drives the blade to move inward when the connecting rod moves. The two sets of separation components operate simultaneously, so that the two blades and the cutoff point of the disposable sampling rod are cut off at the same time, completing the separation of the disposable sampling rod. The sampling head with the sample falls into the preservation bottle, which can properly preserve the sampling head to avoid contact with the sampling head during the direct breaking process, thereby improving the hygiene of the sampling and ensuring that both hands do not touch the disposable sampling rod during the sampling process to avoid contamination.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0026] Combination Figure 1-Figure 2 A side-push cervical sampler with a sampling head storage and anti-pollution function, comprising a protective tube 1, a disposable sampling rod 4 for sampling is arranged inside the protective tube 1, and a rotating assembly 2 for rotation is installed at one end of the disposable sampling rod 4, and pushing assemblies 3 are arranged on both sides of the rotating assembly 2, and a separation assembly 5 is arranged inside the protective tube 1;

[0027] The utility model is further described below in conjunction with embodiments.

[0028] Embodiment 1:

[0029] See also Figure 3-Figure 5 , moving grooves 11 are opened on both sides of the protective tube 1, and the inner diameter of the protective tube 1 is larger than the diameter of the rotating component 2, so that the moving grooves 11 can limit the moving direction.

[0030] The rotating assembly 2 includes a mounting rod 22 installed at one end of the disposable sampling rod 4, and a fixing ring 23 is movably connected to the outside of the mounting rod 22 through a bearing, and a knob 21 is connected to the other end of the mounting rod 22. The total length of the mounting rod 22 and the disposable sampling rod 4 is greater than the length of the protective tube 1, which can ensure that the mounting rod 22 drives the disposable sampling rod 4 to rotate.

[0031] The pushing assembly 3 includes an extrusion plate 31 hinged on the outside of the fixed ring 23, and a pushing block 32 is connected to the outside of the extrusion plate 31, and a spring 33 is connected to the outside of the extrusion plate 31 and the fixed ring 23. There are two groups of pushing assemblies 3 symmetrically distributed on the outside of the fixed ring 23, so that the fixed ring 23 can be pushed by the pushing assemblies 3 on both sides, thereby extending the disposable sampling rod 4 into the sampling site.

[0032] The push block 32 corresponds to the position of the moving groove 11, and the spring 1 33 squeezes the plate 31 in an inclined state in the initial state to push the push block 32 through the moving groove 11, and the width of the push block 32 is consistent with the width of the moving groove 11, which is convenient for pushing the push block 32 to move, and the fixing ring 23 can be removed at the same time.

[0033] The push block 32 is initially squeezed by the inner wall of the protective tube 1 so that the spring 33 is shortened. When the push block 32 moves to the moving groove 11 area, the squeezing force of the spring 33 disappears. The squeezing plate 31 is used to push the push block 32 into the moving groove 11 area. In the movable groove 11, the sampling head of the disposable sampling rod 4 is arranged inside the protective tube 1, which can prevent the sampling head from contacting other parts of the body before reaching the sampling area, avoid contaminating the sampling head, and better store the unused sampling heads. When sampling is needed, the front end of the protective tube 1 is first inserted into the cervical channel head, and then the pushing block 32 is pushed to move forward along the movable groove 11. The pushing block 32 uses the extrusion plate 31 to drive the fixing ring 23 to move. The fixing ring 23 is movably connected to the mounting rod 22, so the mounting rod 22 follows the movement, thereby driving the disposable sampling rod 4 to move deep into the cervix. The moving distance is adjusted according to personal circumstances. When the disposable sampling rod 4 moves to the specified position, the knob 21 is rotated, and the knob 21 uses the mounting rod 22 to drive the disposable sampling rod 4 to rotate to collect the external cervical sample. After rotating five times in the same direction, the collection work is completed, which can ensure that the disposable sampling rod 4 does not contact other skin when in use, ensure the quality of collection, and prevent the disposable sampling rod 4 from being contaminated.

[0034] Embodiment 2:

[0035] See also Figure 6 The separation assembly 5 includes a connecting rod 52 slidably connected to the outside of the protective tube 1, and one end of the connecting rod 52 is connected to a blade 53, and the other end of the connecting rod 52 is connected to a button 51, which can enable the connecting rod 52 to drive the blade 53 to move.

[0036] The disposable sampling rod 4 is composed of a sampling head and a sampling rod, and a truncation point is arranged on the sampling rod near the sampling head. The sampling head is made of flexible material, so that the disposable sampling rod 4 can be cut into a suitable length and put into the storage bottle.

[0037] When the pushing block 32 moves to the end of the moving groove 11, the blade 53 is aligned with the truncation point on the disposable sampling rod 4, and the separation component 5 is provided with two groups on the side of the truncation point to ensure the quality of truncation. The blades 53 on both sides move at the same time, and the separation component 5 will not enter the inside of the cervix.

[0038] The button 51 is arranged outside the protective tube 1, and a silicone material is arranged at the front end of the protective tube 1. A spring 54 is connected between the outside of the protective tube 1 and the button 51, which can automatically reset the button 51 and reduce the pain when the protective tube 1 made of silicone material contacts the body.

[0039] Specifically, when the disposable sampling rod 4 has completed the collection, the protective tube 1 is slowly removed from the cervix as a whole, the pushing block 32 is moved to the end of the moving groove 11, and the preservation bottle is taken out, and the sampling brush at the front end of the disposable sampling rod 4 is placed in the preservation bottle. In order to avoid direct contact with the disposable sampling rod 4 and contamination of the disposable sampling rod 4 after sampling, the buttons 51 on both sides of the protective tube 1 can be pressed inwardly. Since the truncation point on the disposable sampling rod 4 is aligned with the position of the blade 53 when the pushing block 32 moves to the end, the button 51 moves inwardly to push the connecting rod 52 to move inward. When the button 51 and the outer wall of the protective tube 1 are moved, the spring 54 between the button 51 and the outer wall of the protective tube 1 is squeezed, and the blade 53 is driven to move inward when the connecting rod 52 moves. The two sets of separation components 5 operate simultaneously, so that the two blades 53 and the truncation points of the disposable sampling rod 4 are cut off at the same time, and the separation work of the disposable sampling rod 4 is completed. The sampling head with the sample adhered falls into the preservation bottle, which can properly preserve the sampling head and avoid contact with the sampling head during the direct breaking process, thereby improving the hygiene of sampling and ensuring that both hands do not touch the disposable sampling rod 4 during the sampling process to avoid contamination.
