Technical Field

[0001] This invention relates to the field of sampling device technology, specifically to a gastroenterology vomitus sampling device with compartments. Background Technology

[0002] Vomitus can reflect a variety of diseases, such as nervous vomiting, acute gastritis, pyloric obstruction, and duodenal obstruction. In the process of gastroenterology nursing, it is often necessary to take samples of the patient's vomitus for testing in order to further determine the symptoms.

[0003] Most current vomit sampling devices have the following drawbacks: they require excessive human intervention, and negative pressure is created manually to collect vomit samples, but prolonged close contact with vomit can easily lead to infection risks. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide a gastroenterology vomit sampling device that can automatically collect vomit samples and is easy to replace the sampling tube.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gastroenterology vomitus sampling device, comprising a base and a controller, and further comprising: A top plate, which is disposed above the base and is fixedly connected to the base by a fixed shaft; A rotating cylinder, which is sleeved on the outside of the fixed shaft and rotatably connected to the base; A drive assembly for controlling the rotation of the rotating cylinder; Multiple sampling mechanisms are provided, each corresponding to one of the guide grooves. Each sampling mechanism includes a guide rod, a slider, a spring, a lifting block, and a sampling assembly. The guide rod is arranged longitudinally and its two ends are fixedly connected to the rotating cylinder. The slider is disposed on the guide rod and slidably connected to the guide rod. The spring causes the slider to have an upward tendency. The lifting block is fixedly installed on the slider. The top of the lifting block forms a horizontally extending first horizontal surface and a downwardly inclined first inclined surface. A guide plate is disposed on the outside of the rotating cylinder and is fixedly connected to the top plate by a connecting plate. The bottom of the guide plate has a horizontally extending second horizontal surface and an upwardly inclined second inclined surface, the second inclined surface being adapted to the first inclined surface. The lifting component is used to control the sampling component to extract vomit when the first horizontal plane is in contact with the second horizontal plane.

[0006] Furthermore, the sampling assembly includes a sampling cylinder, a piston, a piston rod, and a pull plate. The sampling cylinder is arranged longitudinally and inserted into the lifting block. A liquid inlet pipe is fixedly installed at the bottom of the sampling cylinder. The piston is disposed inside the sampling cylinder and slides in contact with the inner wall of the sampling cylinder while maintaining a seal. The pull plate is fixedly installed at the top of the piston rod.

[0007] Furthermore, the lifting assembly includes a movable rod, a limiting block, a guide shaft, a guide member, and a first motor; The movable rod passes longitudinally through the connecting plate and is slidably connected to the connecting plate. The limiting block is fixedly installed at the bottom of the movable rod. The limiting block has a T-shaped groove that runs horizontally through it and communicates with its bottom. The T-shaped groove is adapted to the pull plate and the piston rod. The guide shaft is arranged horizontally above the connecting plate and is connected to the movable rod. The first end of the guide member is rotatably connected to the top plate. The second end of the guide member has a guide groove that runs horizontally through it. The inner wall of the guide groove is in contact with the guide shaft. The first motor is electrically connected to the controller and is used to control the rotation of the first end of the guide member.

[0008] Furthermore, the guide shaft is rotatably connected to the movable rod, and the guide shaft makes rolling contact with the inner wall of the guide groove.

[0009] Furthermore, a baffle is fixedly installed on the guide shaft to prevent the guide shaft from disengaging from the guide groove.

[0010] Furthermore, the drive assembly includes a gear ring, a second motor, and a gear. The gear ring is fixedly mounted on the inner wall of the rotating cylinder, the second motor is fixedly mounted on the base and electrically connected to the controller, and the gear is fixedly mounted on the second motor and meshes with the gear ring.

[0011] Furthermore, the outer circumferential surface of the rotating cylinder has multiple longitudinally extending grooves, and both the guide rod and the slider are located within the grooves.

[0012] Furthermore, the spring is sleeved on the guide rod, with the first end of the spring fixedly connected to the inner wall of the groove and the second end of the spring fixedly connected to the slider.

[0013] Furthermore, a sheath is provided on the inlet pipe, and the sheath is threadedly connected to the inlet pipe.

[0014] Furthermore, a handle is fixedly installed on the top plate.

[0015] The beneficial effects of this invention are as follows: This invention provides a vomitus sampling device for gastroenterology. Under the action of a guide plate, the slider and lifting block move the sampling cylinder downwards until the inlet tube extends into the vomitus. Then, the lifting assembly is activated, moving the pull plate, piston rod, and piston upwards. At this time, the negative pressure formed inside the sampling cylinder draws the vomitus into the sampling cylinder, thus automatically completing the sampling of the vomitus. Furthermore, in this invention, the sampling cylinder is inserted into the lifting block and located outside the device, making it very easy to replace the sampling cylinder.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly defined.

[0022] like Figures 1-8 As shown, this invention provides a vomitus sampling device for gastroenterology, including a base 10, a power supply, and a controller. A support leg 11 is fixedly installed at the bottom of the base 10. The base 10, power supply, and controller are all prior art, and their specific structures will not be described in detail here. The device also includes a top plate 20, a rotating cylinder 30, a drive assembly 40, a sampling mechanism 50, a guide plate 60, and a lifting assembly 70.

[0023] The top plate 20 is positioned horizontally above the base 10 and is fixedly connected to the base 10 via a fixed shaft 22.

[0024] The rotating cylinder 30 is sleeved on the outside of the fixed shaft 22 and rotatably connected to the base 10. Specifically, the bottom of the rotating cylinder 30 has an annular groove 31, and an annular guide rail 12 is fixedly installed on the base 10. The rotational connection between the rotating cylinder 30 and the base 10 is achieved through the cooperation of the annular groove 31 and the annular guide rail 12.

[0025] The drive assembly 40 is used to control the rotation of the rotating cylinder 30.

[0026] There are multiple sampling mechanisms 50, each corresponding to a specific guide groove 741. Each sampling mechanism 50 includes a guide rod 51, a slider 52, a spring 53, a lifting block 54, a sampling cylinder 55, a piston 56, a piston rod 57, and a pull plate 58. The guide rod 51 is longitudinally positioned on the outer side of the rotating cylinder 30, with both ends fixedly connected to the rotating cylinder 30. The slider 52 is mounted on the guide rod 51 and slidably connected to it. The spring 53 causes the slider 52 to tend to move upwards. The lifting block 54 is fixedly mounted on the slider 52, and its top has a horizontally extending first horizontal surface 541 and a downwardly inclined first inclined surface 542. The sampling cylinder 55 is longitudinally positioned on the side of the lifting block 54 and is inserted into the lifting block 54. Specifically, an insert block 551 is fixedly installed on the outer circumferential surface of the sampling cylinder 55, and a slot 543 corresponding to the insert block 551 is opened on the lifting block 54. The insertion between the sampling cylinder 55 and the lifting block 54 is achieved through the cooperation of the insert block 551 and the slot 543. A liquid inlet pipe 552 is fixedly installed at the bottom of the sampling cylinder 55, and the liquid inlet pipe 552 communicates with the interior of the sampling cylinder 55. A piston 56 is disposed inside the sampling cylinder 55, and the piston 56 slides in contact with the inner wall of the sampling cylinder 55 and maintains a seal. A pull plate 58 is fixedly installed laterally on the top of the piston rod 57.

[0027] The guide plate 60 is disposed on the outside of the rotating cylinder 30 and is fixedly connected to the top plate 20 by a connecting plate 63. The bottom of the guide plate 60 has a horizontally extending second horizontal surface 61 and an upwardly inclined second inclined surface 62, the second inclined surface 62 being adapted to the first inclined surface 542.

[0028] When the first horizontal plane 541 contacts the second horizontal plane 61, the lifting assembly 70 is used to control the pull plate 58 to move upward.

[0029] In the initial state, the spring 53 is in the extended state, the slider 52 and the lifting block 54 are both located at the top of the guide rod 51, and the piston 56 is located at the bottom of the inner wall of the sampling cylinder 55.

[0030] The specific sampling procedure of this device is as follows: First, medical staff placed the device on the ground near the vomit.

[0031] Then, the drive assembly 40 operates, controlling the rotating cylinder 30 to rotate. The sampling mechanism 50 adjacent to the rotating cylinder 30 will first interact with the guide plate 60. Specifically, the first inclined surface 542 on the lifting block 54 will first contact the second inclined surface 62 on the guide plate 60. As the rotating cylinder 30 continues to rotate, under the guidance of the second inclined surface 62, the slider 52 and the lifting block 54 will drive the sampling cylinder 55 to move downward until the inlet pipe 552 extends into the vomit. At this time, the first inclined surface 542 and the second inclined surface 62 disengage, and the first horizontal surface 541 contacts the second horizontal surface 61. The drive assembly 40 controls the rotating cylinder 30 to stop rotating, and the spring 53 is in a compressed state.

[0032] Next, the lifting component 70 operates, driving the pull plate 58, piston rod 57 and piston 56 to move upward. At this time, the negative pressure formed in the sampling cylinder 55 will suck the vomit into the sampling cylinder 55, thereby automatically completing the sampling of the vomit.

[0033] Finally, the drive assembly 40 controls the rotating cylinder 30 to continue rotating until the first horizontal plane 541 disengages from the second horizontal plane 61. At this point, under the action of the spring 53, the slider 52 and the lifting block 54 will return to the top of the guide rod 51. Medical staff can attach labels to the sampling cylinder 55 to record the time and identity information of the vomit sampled. Medical staff can then remove the sampling cylinder 55 promptly, or wait for multiple sampling cylinders 55 to collect samples separately before collecting them all at once.

[0034] As can be seen from the above steps, the sampling process of this device is completed automatically. Medical staff only need to place the device on the ground near the vomit, requiring minimal human intervention and thus reducing the risk of infection. Furthermore, in this device, the sampling cylinder 55 is located outside the device and is inserted through the cooperation of the insert block 551 and the slot 543, making it very easy to replace the sampling cylinder 55.

[0035] It is worth noting that this device has multiple sampling mechanisms 50. After one sampling cylinder 55 completes sampling, the drive assembly 40 can control the rotating cylinder 30 to continue rotating, enabling the next sampling cylinder 55 to continue sampling, thus allowing continuous sampling. Furthermore, the operator can determine whether the sampling cylinder 55 has completed sampling by observing whether the piston rod 57 is pulled upward.

[0036] In one embodiment, the lifting assembly 70 includes a movable rod 71, a limiting block 72, a guide shaft 73, a guide member 74, and a first motor 75.

[0037] The movable rod 71 passes longitudinally through the connecting plate 63 and is slidably connected to the connecting plate 63. A limiting block 72 is fixedly installed at the bottom of the movable rod 71. The limiting block 72 has a T-shaped groove 721 that runs transversely through it and communicates with its bottom. The T-shaped groove 721 is adapted to the pull plate 58 and the piston rod 57. A guide shaft 73 is transversely positioned above the connecting plate 63 and connected to the movable rod 71. The first end of the guide member 74 is rotatably connected to the top plate 20. The second end of the guide member 74 has a guide groove 741 that runs transversely through it, and the inner wall of the guide groove 741 contacts the guide shaft 73. A first motor 75 is fixedly installed on the top plate 20 and electrically connected to the controller. The first motor 75 is used to control the rotation of the first end of the guide member 74.

[0038] When the first horizontal plane 541 contacts the second horizontal plane 61, the pull plate 58 and the piston rod 57 are just located in the T-slot 721, and the lifting assembly 70 is working at this time.

[0039] When the lifting component 70 is working, the controller controls the first motor 75 to start, which in turn drives the first end of the guide 74 to rotate, and the second end of the guide 74 to swing upward. The guide shaft 73 moves in the guide groove 741 and drives the movable rod 71 to move upward. The limit block 72 then drives the pull plate 58, piston rod 57 and piston 56 to move upward to perform sampling.

[0040] After the sampling operation is completed, the drive assembly 40 controls the rotating cylinder 30 to continue rotating, and the pull plate 58 and piston rod 57 will automatically disengage from the T-slot 721.

[0041] The lifting component 70 has a simple and ingenious structure, is easy to manufacture, and does not obstruct or affect the rotation of the rotating cylinder 30.

[0042] In one embodiment, the guide shaft 73 is rotatably connected to the movable rod 71, and the guide shaft 73 rolls in contact with the inner wall of the guide groove 741.

[0043] When the lifting assembly 70 is activated, the second end of the guide member 74 swings upward, and the guide shaft 73 rolls in the guide groove 741, which in turn drives the movable rod 71 to move upward.

[0044] This design reduces the friction between the guide shaft 73 and the inner wall of the guide groove 741, making the device operate more smoothly.

[0045] In one embodiment, a baffle 76 is fixedly installed on the guide shaft 73. The baffle 76 is used to prevent the guide shaft 73 from disengaging from the guide groove 741, thereby improving the stability of the device.

[0046] In one embodiment, the drive assembly 40 includes a gear ring 41, a second motor 42, and a gear 43. The gear ring 41 is fixedly mounted on the inner wall of the rotating cylinder 30. The second motor 42 is fixedly mounted on the base 10 and electrically connected to the controller. The gear 43 is fixedly mounted on the second motor 42 and meshes with the gear ring 41.

[0047] When the drive component 40 is working, the controller controls the second motor 42 to start, and the second motor 42 will drive the gear 43 to rotate. Under the meshing action of the gear 43 and the gear ring 41, the gear ring 41 will drive the rotating cylinder 30 to rotate.

[0048] In one embodiment, a plurality of longitudinally extending grooves 32 are formed on the outer peripheral surface of the rotating cylinder 30, and the guide rod 51 and the slider 52 are both located in the grooves 32.

[0049] This concealed design further reduces the size of the device, making it more convenient to carry and use.

[0050] In one embodiment, spring 53 is sleeved on guide rod 51, with the first end of spring 53 fixedly connected to the inner wall of slide groove 32 and the second end of spring 53 fixedly connected to slider 52.

[0051] This improves the stability of spring 53, prevents spring 53 from bending when compressed, and further enhances the stability of the device.

[0052] In one embodiment, a sheath 553 is provided on the inlet tube 552, and the sheath 553 is threadedly connected to the inlet tube 552. Before sampling, medical staff can remove the sheath 553, and after sampling is completed, the sheath 553 can be put back on.

[0053] In one embodiment, a handle 21 is fixedly installed on the top plate 20 to facilitate carrying the device.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
