Description

Technical Field

[0001] The invention belongs to the technical field of medical sampling, and in particular relates to a gynecological vaginal secretion sampling device. Background Art

[0002] Gynecological clinical instruments are widely used in medicine. In gynecological clinical practice, it is necessary to sample and test the secretions inside the vagina. Therefore, a vaginal secretion sampling device for gynecological clinical practice is needed to sample it. The existing sampling device design structure is too simple, and the sampling process is relatively single. It is not possible to perform stratified sampling of secretions at different depths of the vagina. Since the secretion content at different depths is different, the test results of the patient's vaginal secretions are often not accurate enough, and multiple samplings are required for testing. Not only is the operation very cumbersome and affects the detection efficiency, but frequent sampling operations can easily cause infection in the patient's vagina. Therefore, the overall convenience, efficiency and practicality are generally not high. Therefore, it is necessary to improve the existing vaginal secretion sampling device used in gynecological clinical practice, design a new vaginal secretion sampling device used in gynecological clinical practice to change the above-mentioned technical defects, and improve the overall practicality of the vaginal secretion sampling device used in gynecological clinical practice.

[0019] 2. Secondly, the present invention provides a first opening and a second opening. After sampling is completed, the first opening and the second opening are communicated by rotating the plug. At this time, the inner plate is pushed away from the inner wall of the supporting shell under the elastic action of the spring, thereby squeezing the expanded liquid sac, and the physiological saline in the liquid sac and the fixed tube will flow into the supporting shell, and the physiological saline will seep outward from the cylinder passing through the supporting shell, thereby dripping the physiological saline into the patient's vagina, thereby facilitating the subsequent use of a sterile cotton swab to clean the patient's vagina.

[0020] 3.

At the same time, after the sealing mechanism is placed in the outer shell together with the support mechanism and the sampling mechanism, the top of the outer shell will be blocked to further prevent the sample from being contaminated by contact with the outside world.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 10 As shown, an embodiment of the present invention provides a gynecological vaginal secretion sampling device, comprising a housing 1, and further comprising:

[0034] The capping mechanism 2 includes an inner cover 21 and an outer cover 22. The top surface of the inner cover 21 is provided with a plurality of centrally symmetrical through slots 24. The outer cover 22 is rotatably mounted on the outer side of the inner cover 21. The capping mechanism 2 is fixedly sleeved in the outer shell 1.

[0035] The support mechanism 3 includes a rubber head 31, the bottom surface of the rubber head 31 is in an arc shape, the top surface of the rubber head 31 is fixedly connected with a fixing tube 32 and a supporting shell 33, the fixing tube 32 is located at the center of the top surface of the rubber head 31, and the axis of the supporting shell 33 coincides with the axis of the fixing tube 32;

[0036] The sampling mechanism 4 includes a plurality of rubber plates 41 located outside the support shell 33 and an inner plate 44 located inside the support shell 33. The outer side of the rubber plate 41 is provided with a mounting groove 42. A mounting head 43 is rotatably mounted inside one end of the mounting groove 42 close to the rubber head 31. A rotating rod 46 is movably connected in the mounting groove 42. A plurality of sampling cotton blocks 47 are fixedly connected to the side of the rotating rod 46.

[0037] When the bottom surface of the inner cover 21 abuts against the top surface of the support shell 33 , the end of the rotating rod 46 away from the rubber head 31 passes through the through slot 24 .

[0038] In the present invention, by setting up a plurality of sampling mechanisms 4, after removing the shell 1 of the present invention, holding the fixing tube 32, inserting the support mechanism 3 and the sampling mechanism 4 into the lower body of the patient, and then injecting physiological saline into the fixing tube 32 through the injection tube 39. As the liquid is injected, the liquid bag 38 expands and becomes larger, thereby pushing the inner plate 44 to move toward the inner wall direction of the supporting shell 33, and then driving the rubber plate 41 to move outward. When the rubber plate 41 contacts the inner wall of the patient's vagina, the injection of physiological saline is stopped, and then the outer cover 22 is rotated. At this time, the outer cover 22 will drive the tooth block 28 to rotate, thereby driving the gear 29 to rotate, and the gear 29 drives the rotating rod 46 inside it to rotate, so that the sampling cotton block 47 rotates to dip the secretions in the patient's vagina. By setting up a plurality of sampling cotton blocks 47, a single rotating rod 46 samples the secretions of different depths of the patient, and the setting of multiple rotating rods 46 enables the device to sample secretions at different positions, thereby enriching the samples.

[0039] Secondly, the present invention provides a first opening 310 and a second opening 311. After sampling is completed, the first opening 310 and the second opening 311 are connected by rotating the plug 37. At this time, the inner plate 44 is pushed away from the inner wall of the support shell 33 under the elastic action of the spring 48, thereby squeezing the expanded liquid sac 38. The physiological saline in the liquid sac 38 and the fixed tube 32 will flow into the support shell 33, and the physiological saline will seep outward from the cylinder passing through the support shell 33, thereby dripping the physiological saline into the patient's vagina, thereby facilitating the subsequent use of a sterile cotton swab to clean the patient's vagina.

[0040] Finally, through the provided groove 35 and the accommodating opening 45, as the rotating outer cover 22 drives the rotating rod 46 to rotate, after the patient's secretions are extracted, the outwardly protruding part of the sampling cotton block 47 enters the accommodating opening 45 and the groove 35, and then the bracket mechanism 3 and the sampling mechanism 4 are placed in the outer shell 1, thereby preventing the sampling sample from being contaminated by the outside world during transportation. At the same time, after the sealing mechanism 2 is placed in the outer shell 1 together with the bracket mechanism 3 and the sampling mechanism 4, the top of the outer shell 1 will be blocked to further prevent the sample from contacting with the outside world and being contaminated.

[0041] Among them, a traction plate 25 is slidably connected in the through slot 24, a mounting hole 26 communicating with the through slot 24 is provided on the top surface of the traction plate 25, a traction column 27 is fixedly connected to the top surface of the traction plate 25, a plurality of centrally symmetrical tooth blocks 28 and gears 29 are arranged between the inner cover 21 and the outer cover 22, the gear 29 is fixedly sleeved on the rotating rod 46, an arc groove 211 is provided on the bottom surface of the tooth block 28, two limiting columns 210 are fixedly connected to the top surface of the tooth block 28, a plurality of groups of straight grooves 23 are provided on the bottom surface of the outer cover 22, the limiting columns 210 are slidably connected in the straight grooves 23, and the traction column 27 is slidably connected in the arc groove 211.

[0042] like Figures 4 to 7 As shown, the outer cover 22 of the sealing mechanism 2 is sleeved on the inner cover 21, and a plurality of through slots 24 communicating with the open slots 36 on the top of the support shell 33 are opened on the inner cover 21. After the installation of the rotating rod 46 is completed, one end of the rotating rod 46 passes through the through slot 24 and the mounting hole 26 and is fixedly sleeved in the gear 29. When physiological saline is injected into the fixed tube 32 later, as the liquid bag 38 expands, the sampling mechanism 4 moves outward as a whole. At this time, the rotating rod 46 slides in the through slot 24, driving the gear 29 to move together. Driven by the traction plate 25, the tooth block 28 moves with the gear 29, so that the tooth block 28 always keeps meshing with the gear 29, so that no matter where the rotating rod 46 moves to the through slot 24, the rotating outer cover 22 can always drive the rotating rod 46 to rotate, thereby making the application scope of the present invention wider.

[0043] The outer side surface of the support shell 33 is provided with a plurality of grooves 35 arranged vertically and symmetrically, the outer side surface of the rubber plate 41 is provided with a plurality of receiving openings 45 arranged vertically, the sampling cotton block 47 is located in the receiving openings 45, and the receiving openings 45 and the grooves 35 correspond one to one.

[0044] Through the provided groove 35 and the receiving port 45, as the rotating outer cover 22 drives the rotating rod 46 to rotate, after the patient's secretions are extracted, the outward protruding part of the sampling cotton block 47 enters the receiving port 45 and the groove 35, and then the device is placed in the outer shell 1 to complete the sampling and packaging of the secretions, preventing the secretions from excessive contact with the external environment and causing contamination.

[0045] Among them, the inner side surface of the rubber plate 41 is fixedly connected to the inner plate 44 through a cylinder penetrating the support shell 33, and a spring 48 is movably sleeved on the cylinder. A plurality of inner brackets 34 are fixedly connected inside the support shell 33, and a liquid capsule 38 is fixedly connected to the inner bracket 34, and the expansion surface of the liquid capsule 38 faces the corresponding inner plate 44.

[0046] like Figures 3 to 10As shown, after physiological saline is injected to drive the liquid sac 38 to expand, the liquid sac 38 drives the inner plate 44 and the rubber plate 41 to move outward, and as the inner plate 44 moves, the spring 48 is compressed, which makes the inner plate 44 move slower the closer it is to the inner wall of the support shell 33, thereby preventing the rubber plate 41 from moving too fast and quickly contacting the inner wall of the patient's vagina, thereby causing harm to the patient. At the same time, the spring 48 also plays a role in driving the sampling mechanism 4 to return after the sampling is completed.

[0047] Among them, the liquid bag 38 is connected to and communicated with the fixed tube 32, a plug 37 is clamped on the top of the fixed tube 32, an injection tube 39 is fixedly connected to the inner top surface of the plug 37, the injection tube 39 is communicated with the top surface of the plug 37, a first opening 310 is opened on the outer side surface of the fixed tube 32, a second opening 311 is opened on the outer side surface of the plug 37, and the inner plate 44 is penetrated by the connecting column between the inner bracket 34 and the support shell 33.

[0048] like Figure 3 , Figure 4 and Figure 8 , Fig. 9 As shown, the plug 37 and the fixed tube 32 are interference fit and can be rotated, and the top of the injection tube 39 is made of rubber material that can be automatically closed. When the first opening 310 and the second opening 311 do not match, physiological saline is injected into the interior of the fixed tube 32, and the physiological saline enters the liquid capsule 38. After the sampling is completed, the plug 37 is rotated to make the first opening 310 and the second opening 311 match. At this time, the physiological saline in the liquid capsule 38 will be squeezed out under the action of the spring 48, thereby overflowing from the part of the support shell 33 penetrated by the cylinder and dripping into the patient's vagina, so that the sampling personnel can use a cotton swab to directly clean the patient's vagina after the sampling is completed, without the need to frequently dip in physiological saline.

[0049] The top diameter of the support shell 33 is larger than the bottom diameter. The top surface of the support shell 33 is provided with a plurality of centrally symmetrical open grooves 36 , and the open grooves 36 are communicated with the top side surface of the support shell 33 .

[0050] like Figure 8 As shown, when installing the rotating rod 46 on the sampling mechanism 4, first insert one end of the rotating rod 46 into the mounting head 43, then make the protruding part of the sampling cotton block 47 face the accommodating port 45 and put the rotating rod 46 into the open groove 36, then press the rotating rod 46 and make it snap into the mounting groove 42, so as to facilitate the installation of the rotating rod 46. At the same time, when the sampling mechanism 4 moves outward, the open groove 36 also guides the rotating rod 46 to prevent the rotating rod 46 from shaking during the sampling process, resulting in inaccurate sampling and injury to the patient.

[0051] The inner cover 21 and the outer cover 22 are both slidably sleeved on the outer side of the fixed tube 32, the top of the support shell 33 is interference fit with the inner cover 21, and when the bottom surface of the inner cover 21 abuts against the top surface of the support shell 33, the inner cover 21 cannot rotate.

[0052] After the rotating rod 46 is inserted into the mounting groove 42, the inner cover 21 and the outer cover 22 are sleeved on the fixing tube 32. After the rotating rod 46 is aligned with the inner ring of the gear 29, the sealing mechanism 2 is pushed. At this time, the rotating rod 46 is fixedly sleeved in the gear 29, and the inner cover 21 is stuck in the top protruding part of the supporting shell 33. By setting the two to be an interference fit, the inner cover 21 is prevented from rotating when the outer cover 22 is rotated, thereby preventing the rotating rod 46 from being deflected or broken due to rotation, thereby causing injury to the patient.

[0053] Working principle:

[0054] Before sampling, first remove the outer shell 1 from the other parts, then take out the rotating rod 46 with the sampling cotton block 47, and then insert one end of it into the mounting head 43, then make the raised part of the sampling cotton block 47 face the accommodating port 45 and put it into the corresponding open groove 36, then press the rotating rod 46 to make it embedded in the mounting groove 42, then put the inner cover 21 and the outer cover 22 on the fixed tube 32, align one end of the rotating rod 46 with the inner ring of the gear 29, press the inner cover 21 to close the support shell 33, and finally install the plug 37 into the top end of the fixed tube 32, while ensuring that the first opening 310 and the second opening 311 are staggered.

[0055] When using the device to sample the patient's vaginal secretions, the capping mechanism 2, the support mechanism 3 and the sampling mechanism 4 are sterilized and then inserted into the patient's vagina. Then, physiological saline is injected into the fixed tube 32 through the injection tube 39 by an infusion device such as a syringe. As the physiological saline enters the liquid bag 38, the liquid bag 38 expands and becomes larger, thereby pushing the inner plate 44 to move toward the inner wall of the support shell 33, thereby driving the rubber plate 41 to move outward. As the rubber plate 41 contacts the inner wall of the patient's vagina, the injection of physiological saline is stopped. Then, the fixed tube 32 is held with one hand, and the outer cover 22 is rotated with the other hand. As the outer cover 22 rotates, it drives the tooth block 28 to rotate through the limit column 210, so that The gear 29 is driven to rotate, and as the gear 29 rotates, the rotating rod 46 drives the sampling cotton block 47 to rotate and dip the patient's secretions. After the rotating rod 46 rotates an integer number of circles, the protruding end of the sampling cotton block 47 dipped in the secretions is located in the accommodating port 45 and the groove 35 to prevent direct contact with the supporting shell 33. Then the plug 37 is rotated to connect the first opening 310 and the second opening 311, so that the liquid in the liquid bag 38 flows into the supporting shell 33 due to the squeezing of the spring 48, and then overflows from the pierced part of the supporting shell 33 and drips into the patient's vagina. At this time, under the action of the spring 48, the sampling mechanism 4 is reset, and then the device is taken out and loaded into the outer shell 1, thereby completing the packaging of the sample.
