Description

Technical Field

[0001] The utility model relates to the technical field of medical sampling, in particular to a side-pushing cervical sampler. Background Art

[0002] Cervical cytology is currently the basic method for screening cervical lesions, and a cervical sampler is usually required. At present, cervical exfoliated cell sampling is usually performed in medical institutions by doctors and other professionals, who use a vaginal dilator to expose the cervix and use a cervical scraper, cervical brush or sampling swab to collect cervical epidermal exfoliated cells / secretions. In order to reduce the difficulty of sampling and protect privacy, many cervical samplers have appeared on the market that allow users to operate directly without the help of medical staff and the use of dilators, such as the cervical sampler with patent publication number CN217566127U.

[0003] Most of the above samplers are of the direct-insertion self-spinning type. When in use, the rotating rod at the bottom of the sampler is rotated to drive the sampling head to rotate and telescope along the axial direction through the thread, and the sampling head is used for sampling. However, there are the following technical problems: this transmission method will cause the sampling head to rotate synchronously when moving in the vagina, which is easy to increase the scratching of the sampling head on the vaginal wall and cause discomfort to the user; during operation, one hand needs to hold the fixed disk and the other hand to rotate the rotating rod, and the operation process is relatively cumbersome; in addition, the user cannot accurately sense whether the sampling head has reached the sampling position.

[0004] It can be seen that the above sampling method still has defects and needs to be improved. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a side-push type cervical sampler.

[0006] The solution adopted by the utility model to solve its technical problems is: a side-push type cervical sampler, including a sampling head, a front sleeve, a telescopic rod and a rear sleeve, wherein the sampling head is fixed at the front end of the telescopic rod, the front sleeve is a hollow structure with openings at both ends, a conical opening is arranged at the front end, and an arc-shaped baffle is arranged at the rear end, the front end of the telescopic rod is sleeved in the front sleeve, and the rear end is sleeved in the rear sleeve, the rear sleeve is a hollow structure with one end open and the other end closed, the open end of the rear sleeve is sleeved with the front sleeve, and a slide groove is arranged on the side wall of the rear sleeve.

[0007] A sampling head is installed at the front end of the telescopic rod, a breaking groove is arranged on the rear side of the sampling head, a conical limiting boss is arranged on the rear side of the breaking groove, a supporting platform is arranged on the rear side of the conical limiting boss, a clamping claw is arranged on the supporting platform along the direction of the rod, a limiting ring is arranged at the tail end of the telescopic rod, the limiting ring extends outward through the sliding groove on the rear sleeve and has a push button, and the telescopic rod is pushed to slide and retract in the front and rear sleeves through the push button.

[0008] Furthermore, the sampling head is a sponge or flocking head, and the sampling head is fixed on the telescopic rod by gluing or hot pressing.

[0009] Furthermore, an annular groove is provided in the middle of the front sleeve, and a claw in the middle of the telescopic rod can be buckled with the annular groove.

[0010] Furthermore, a square protrusion protruding inward is arranged on the inner side of the rear end of the front sleeve, the rear sleeve is sleeved in the front sleeve, and the square protrusion is clamped in the sliding groove of the rear sleeve.

[0011] Furthermore, a rotating part is provided at the tail end of the rear sleeve, and strip-shaped grooves are evenly provided along the axial direction on the rotating part to increase the friction when contacting the user's hand.

[0012] Furthermore, the bottom of the push button is a square structure, and its upper surface is inclined downward toward the tail end of the rear sleeve. The surface of the push button is provided with a cylindrical protrusion to increase the friction between the push button and the user's fingers.

[0013] Beneficial effects of the utility model: The utility model provides a side-push cervical sampler. On the one hand, the sampling head of the sampler does not rotate when moving in the vagina, which can reduce the scratching of the inner wall of the vagina when the sampling head moves, and relieve the discomfort of the patient. At the same time, when reaching the predetermined position, in addition to the sampling head being unable to continue to extend or retract axially, the user will also hear a "ticking" sound. On the other hand, sampling can be completed with only one hand during operation, which is easy to operate.

[0014] The side-push cervical sampler has a limiting device, so that the telescopic rod can only move axially along the front and rear sleeves, so that the sampling head can only slide axially in the vagina, thereby reducing the scratching of the brush head on the inner wall of the vagina.

[0015] The claw-type claws arranged symmetrically on the support ring in the middle of the telescopic rod contact the inner walls of the front and rear sleeves to produce elastic deformation and generate a certain resistance to prevent the sampling head from extending too quickly and causing discomfort to the user. When the telescopic rod reaches the limited position, in addition to being unable to continue axial movement, the claws return to their original shape and hit the inner wall of the groove of the front sleeve, making a "ticking" sound, reminding the user that the designated sampling position has been reached.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below.

[0022] Example 1: Figure 1 and 2 As shown, the utility model provides a side-push cervical sampler, which includes four parts: a sampling head 1, a front sleeve 2, a telescopic rod 3, and a rear sleeve 4. The sampling head 1 is fixed to the front end of the telescopic rod 3; the front sleeve 2 is a hollow structure with two ends open, wherein the front end is set as a conical opening 21, and the rear end is provided with an arc-shaped baffle 23; the front end of the telescopic rod 3 is sleeved in the front sleeve 2, and the rear end is sleeved in the rear sleeve 4; the rear sleeve 4 is a hollow structure with one end open and the other end closed, and the front end is provided with an annular protrusion 41, which is coaxially sleeved with the rear end of the front sleeve 2, and a slide groove 42 is opened in the hollow part, and the slide groove 42 runs through the open end of the rear sleeve 4, and the rear end is evenly provided with grooves along the axial direction, which serve as the rotating part 43 of the sampler.

[0023] The front end of the front sleeve 2 is a tapered opening to prevent the front sleeve 2 from scratching the inner wall of the vagina when inserted and used, causing discomfort; Figure 3 and Figure 4 As shown, an annular groove 22 is provided in the middle of the inner side of the front sleeve 2. When the telescopic rod 3 is extended to a limited length, it is buckled with a claw 34 provided in the middle of the telescopic rod 3. In addition to limiting the telescopic rod 3 to retract into the inside and outside of the front and rear sleeves 4 during sampling, the claw 34 resumes its free state here, and makes a "ticking" sound when hitting the groove, reminding the user that the designated sampling position has been reached; an arc-shaped baffle 23 is provided at the rear end to limit the depth of the sampler inserted into the vagina, and a square protrusion 24 is provided on the inner side of the rear end, which is sleeved with the slide groove 42 of the rear sleeve 4 to ensure the synchronous rotation of the front and rear sleeves 4.

[0024] The front end of the telescopic rod 3 is provided with a breaking groove 31, and the depth of the breaking groove 31 is one-fourth of its diameter; the front end is also provided with a conical limiting boss 32 to assist in supporting the front end of the telescopic rod 3; a support ring 33 is provided in the middle, and two claws 34 are evenly distributed on the support ring 33. The side-push type cervical sampler described in the utility model is made of medical plastic, and its claws 34 have a certain elasticity. After the telescopic rod 3 is sleeved in the front and rear sleeves 4, the claws 34 always abut against the inner walls of the front and rear sleeves 4 and produce elastic deformation, so that the telescopic rod 3 has a certain resistance when moving axially, preventing it from moving too fast and causing discomfort to the user. A limiting ring 35 is provided at the tail end, which, together with the limiting boss, ensures that the telescopic rod 3 slides coaxially in the front and rear sleeves 4 to prevent the telescopic rod 3 from swinging when it is extended, causing discomfort to the user.

[0025] The limiting ring 35 is provided with a T-shaped push button 36, the bottom of which is a square structure, which is slidably connected in the slide groove 42 of the rear sleeve 4 to prevent the telescopic rod 3 from rotating when the telescopic rod 3 moves axially. The upper part of the push button 36 is provided with a cylindrical protrusion to increase the friction between the user's fingers.

[0026] Under normal conditions, the sampling head 1 is completely retracted into the front and rear sleeves 4 together with the telescopic rod 3. When in use, first insert the front sleeve 2 of the sampler into the vagina until the baffle contacts the vaginal opening. At this time, the user can hold the rear sleeve 4 with one hand and slowly push the push button 36. Under the restriction of the slide groove 42, the sampling head 1 can only move axially along the front and rear sleeves 4 until the outer surface of the limiting boss contacts the inner surface of the opening. At the same time, the claw 34 moves to the groove, recovers from deformation, hits the inner wall of the groove, and makes a "ticking" sound to remind the user that the sampling position has been reached. Then, by holding the rotating part 43, the entire sampler rotates clockwise / counterclockwise to complete the sampling of the cervix.

[0027] Embodiment 2: Based on Embodiment 1, the sampling head 1 is a sponge or flocking head, and the sponge sampling head 1 is fixed on the telescopic rod 3 by gluing or hot pressing.

[0028] At the same time, if Figure 2 As shown, the front end of the rear sleeve 4 is provided with an annular protrusion 41, which is interference fit with the opening at the rear end of the front sleeve 2; a strip-shaped slide groove 42 is provided on one side of the middle part of the rear sleeve 4 along the barrel of the sleeve, and the slide groove 42 close to the opening end of the rear sleeve 4 is clamped on the outside of the square protrusion 24 of the front sleeve 2 to prevent the open end of the rear sleeve 4 from excessive shrinkage and deformation, resulting in the front and rear sleeves 4 cannot be firmly fixed; a rotating part 43 is provided along the sleeve at the rear end, and strip-shaped grooves are evenly provided along the axial direction on the rotating part 43 to increase the friction when in contact with the user's hand.

[0029] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
