Description

Technical Field

[0001] The present invention relates to the technical field of medical testing equipment, and particularly relates to a reagent dosage monitoring device for medical testing. Background Art

[0002] A reagent dosage monitoring instrument for medical testing is a device used to inject reagents and control the reagent dosage during medical testing. However, most of the existing devices use solenoid valves to control the flowing reagents into the test containers during use. This feeding structure and method are prone to inaccurate reagent dosage, affecting the test results.

[0003] Chinese Patent Document CN115993164A discloses a reagent dosage monitoring instrument for medical testing. In this device, the reagent completely fills the upper area inside the reagent container. Therefore, the amount of reagent pushed is the stroke distance of the piston-type liquid pushing plate multiplied by the inner cross-sectional area of the reagent container, making the reagent pushing amount of this device accurate with extremely small errors, suitable for medical tests with accurate dosages. However, in actual use, due to the relatively large volume of the reagent container in this device, the graduation value of the scale set on its surface is relatively large. Therefore, when staff draws reagents, it is impossible to draw a certain volume of reagent more precisely. Summary of the Invention

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. Embodiment

[0018] As Figure 1 — Figure 3 As shown, this embodiment discloses a reagent dosage monitoring device for medical tests, including a housing 1. A dust-proof cover 11 is provided at the upper end of the housing 1. An infusion device 5 adapted to the dust-proof cover 11 is provided in the upper part of the inner cavity of the housing 1. A mounting plate 2 is slidably installed in the lower part of the inner cavity of the housing 1. A liquid storage barrel 4 is provided in the middle of the upper end of the mounting plate 2. The lower end of the infusion device 5 is connected to the upper end of the liquid storage barrel 4 through an infusion tube. One end of the mounting plate 2 is provided with a protection plate 3 slidably connected to the inner surface of the inner cavity of the housing 1. A first measuring cylinder 8 is provided on one side of the outer surface of the housing 1 close to the protection plate 3. The lower part of the first measuring cylinder 8 is connected to the lower part of the liquid storage barrel 4 through an infusion tube, and the bottom wall of the inner cavity of the first measuring cylinder 8 and the bottom wall of the inner cavity of the liquid storage barrel 4 are on the same horizontal plane.

[0019] Specifically, in the daily use of the reagent dosage monitoring device, it is usually necessary to introduce the reagent into the inner cavity of the liquid storage barrel 4 through the infusion device 5 at intervals. In order to prevent dust from falling into the inner cavity of the infusion device 5 and causing the reagent introduced into the inner cavity of the liquid storage barrel 4 to be contaminated, therefore, when the infusion device 5 is not in use, the infusion device 5 can be covered by the dust-proof cover 11 to prevent dust from falling into the inner cavity of the infusion device 5.

[0020] Furthermore, after the reagent dosage monitoring device has been used for a period of time, it may be necessary to clean the liquid storage barrel 4 and other devices. At this time, the staff can pull the protection plate 3 to pull the mounting plate 2 out of the inner and outer parts of the housing 1, and then the liquid storage barrel 4 installed at the upper end of the mounting plate 2 will also be pulled out of the housing 1, facilitating the cleaning work of the liquid storage barrel 4 by the staff.

[0021] Furthermore, during the process of pulling the liquid storage barrel 4 out of the housing 1, since the infusion tube between the liquid storage barrel 4 and the corresponding structure is a soft infusion tube and has a moderate length, the phenomenon that the liquid storage barrel 4 pulls on the connecting tube will not occur.

[0022] Furthermore, since the inner cavity of the first measuring cylinder 8 is communicated with the inner cavity of the liquid storage barrel 4, and under the action of liquid pressure, the first measuring cylinder 8 can reflect the height of the liquid level in the inner cavity of the liquid storage barrel 4, and then the first measuring cylinder 8 can reflect how much volume of reagent is stored in the inner cavity of the liquid storage barrel 4.

[0023] In the daily use of the reagent dosage monitoring device, in order to prevent the reagent in the inner cavity of the liquid storage barrel 4 from being in long-term contact with flowing air and causing the reagent in the inner cavity of the liquid storage barrel 4 to be contaminated, such as Figure 4 andFigure 5 As shown in the figure, the infusion device 5 includes a circular frame 51. The upper end of the circular frame 51 is fixedly installed in the upper part of the inner cavity of the housing 1, and the upper end of the circular frame 51 is flush with the upper end of the housing 1. The circular frame 51 is adapted to be used with the dust-proof cover 11. The inner cavity of the circular frame 51 communicates with the inner cavity of the liquid storage barrel 4 through an infusion tube. A leakage plate 52 is arranged at the lower part of the inner cavity of the circular frame 51. A conical block 53 is arranged in the middle of the upper end of the leakage plate 52. A sealing plate 54 is arranged in the middle of the inner cavity of the circular frame 51. The sealing plate 54 is adapted to be used with the conical block 53. A first deformation ring 55 fixedly connected to the upper end of the leakage plate 52 is arranged on the inner side of the lower end of the sealing plate 54. A first spring 56 is arranged on the outer side of the lower end of the sealing plate 54.

[0024] Specifically, when it is necessary to introduce a reagent into the inner cavity of the liquid storage barrel 4, first open the dust-proof cover 11, and insert the output pipeline of the vessel containing the reagent into the inner cavity of the circular frame 51. If the vessel containing the reagent cannot be inserted into the inner cavity of the circular frame 51, a funnel adapted to the circular frame 51 can be taken and inserted into the inner cavity of the circular frame 51. Then press the vessel or the funnel inserted into the inner cavity of the circular frame 51 to push the sealing plate 54 to move downward. During this process, the first spring 56 will be compressed by force.

[0025] Furthermore, when the sealing plate 54 moves downward, since the conical block 53 is an inverted cone, when the sealing plate 54 moves downward, its inner surface will gradually disengage from the surface of the conical block 53, and the gap between the two will become larger and larger. At this time, the reagent in the vessel or the funnel flows into the lower part of the inner cavity of the circular frame 51 through the gap between the sealing plate 54 and the conical block 53. Then the reagent flows into the inner cavity of the liquid storage barrel 4 through the leakage plate 52 and the infusion tube communicating with the inner cavity of the liquid storage barrel 4.

[0026] Furthermore, after injecting a certain volume of reagent into the inner cavity of the liquid storage barrel 4, there is no need to press the vessel or the funnel anymore. At this time, the first spring 56 will push the sealing plate 54 to move upward, so that the inner surface of the sealing plate 54 is in close contact with the outer surface of the conical block 53 again, avoiding a large amount of flowing air from entering the inner cavity of the liquid storage barrel 4. When extracting the reagent in the inner cavity of the liquid storage barrel 4, the air pressure in the inner cavity of the liquid storage barrel 4 will become lower. At this time, the lower air pressure will overcome the elastic thrust of the first spring 56 and pull the sealing plate 54 to move downward, so that a corresponding volume of air enters the inner cavity of the liquid storage barrel 4.

[0027] Furthermore, the first deformation ring 55 will contract when the sealing plate 54 moves downward. Its structure is similar to the outer structure of a foot-operated air pump. The first deformation ring 55 can prevent the reagent from contacting the surface of the first spring 56. During long-term use, if the first spring 56 is in contact with the reagent for a long time, it may cause the surface of the first spring 56 to rust and contaminate the reagent. Therefore, it is necessary to set the first deformation ring 55 to prevent the reagent from contacting the surface of the first spring 56. Embodiment

[0028] On the basis of the first embodiment, this embodiment further improves the suction device 6, enabling the staff to extract from the inner cavity of the liquid storage barrel 4 according to the amount of reagent required, avoiding waste caused by excessive extraction of reagents. For example Figure 1 and Figure 2 As shown, a suction device 6 is provided in the middle of one side of the outer surface of the housing 1, and a positioning device 7 is provided in the middle of the suction device 6.

[0029] Furthermore, as Figure 7 shown, the suction device 6 includes a support frame 61. A limit frame 62 is provided at the upper part of the support frame 61, and a placement frame 63 is provided at the lower part of the support frame 61. The support frame 61, the limit frame 62, and the placement frame 63 are all fixedly installed in the middle of one side of the outer surface of the housing 1. A suction mechanism 64 is provided in the middle of the inner cavity of the support frame 61, and the upper part of the suction mechanism 64 extends into the inside of the limit frame 62. A lifting plate 65 is provided at the upper part of the suction mechanism 64, and a liquid guide pipe 66 is provided at the lower end of the suction mechanism 64, and the lower part of the liquid guide pipe 66 extends into the inner cavity of the placement frame 63.

[0030] Specifically, when the staff extracts the reagent, first place the corresponding vessel in the inner cavity of the placement frame 63, and then the lifting plate 65 can be pushed upward. By pushing the suction mechanism 64 through the lifting plate 65, the reagent in the inner cavity of the liquid storage barrel 4 is pumped into its inner cavity, and then the extracted reagent is introduced into the corresponding vessel through the liquid guide pipe 66 by the suction mechanism 64.

[0031] Furthermore, the support frame 61, the limit frame 62, and the placement frame 63 are all made of transparent materials. When extracting the reagent, the staff can observe through the limit frame 62 how much volume of reagent the suction mechanism 64 extracts.

[0032] In order to enable the staff to extract the corresponding amount of reagent, as Figure 8 shown, the suction mechanism 64 includes a graduated cylinder II 641. A piston 642 is provided in the middle of the inner cavity of the graduated cylinder II 641. A pull rod 643 is provided at the upper end of the piston 642 and is slidably connected to the upper part of the graduated cylinder II 641. The upper end of the pull rod 643 extends into the inside of the limit frame 62. The upper part of the outer surface of the pull rod 643 is fixedly connected to the inner surface of the lifting plate 65. A limit rod 644 is provided in the middle of the pull rod 643. The upper end of the limit rod 644 extends outside the pull rod 643, and the lower end of the limit rod 644 extends outside the piston 642. A limit member 645 is provided at the lower end of the graduated cylinder II 641.

[0033] Furthermore, the graduation value of the graduated cylinder II 641 is smaller than the graduation value of the graduated cylinder I 8.

[0034] Specifically, when the staff member pushes the lifting plate 65 upward, the lifting plate 65 will drive the piston 642 to move upward through the pull rod 643. During the upward movement of the piston 642, the reagent in the inner cavity of the liquid storage barrel 4 can be sucked into the inner cavity of the graduated cylinder two 641 through the limiting member 645 under the action of air pressure. After extracting the corresponding amount of reagent, the staff member can pull the limiting rod 644 upward, and then the limiting rod 644 drives the limiting member 645 to operate. At this time, the limiting member 645 can no longer introduce the reagent in the inner cavity of the liquid storage barrel 4 into the inner cavity of the graduated cylinder two 641. However, at this time, the inner cavity of the graduated cylinder two 641 is communicated with the inner cavity of the liquid guide tube 66 through the limiting member 645. Then, press the lifting plate 65 downward, so that the lifting plate 65 pushes the piston 642 to move downward through the pull rod 643, and then the piston 642 introduces the reagent in the inner cavity of the graduated cylinder two 641 into the inner cavity of the liquid guide tube 66 through the limiting member 645, so that the liquid guide tube 66 introduces the reagent into the vessel placed in the inner cavity of the placement frame 63. [[ID=~1]] [[ID=~2]]

[0035] Furthermore, during the process of pushing the lifting plate 65 downward, the staff member needs to pull the limiting rod 644 upward throughout the process. [[ID=~4]] [[ID=~5]]

[0036] Furthermore, since the graduation value of the graduated cylinder two 641 is smaller than that of the graduated cylinder one 8, therefore, the staff member can extract the corresponding volume of reagent more precisely. [[ID=~7]] [[ID=~8]]

[0037] In order to prevent the extracted reagent from flowing out of the liquid guide tube 66 after the staff member extracts a certain volume of reagent from the inner cavity of the liquid storage barrel 4 into the inner cavity of the graduated cylinder two 641, which affects the accuracy when the staff member extracts the reagent. As [[ID=~10]] Figure 9 and [[ID=~12]] Figure 10 shown, the limiting member 645 includes a connecting cylinder 6451. The upper end of the connecting cylinder 6451 is fixedly connected to the lower end of the graduated cylinder two 641. The lower end of the connecting cylinder 6451 is fixedly connected to the upper end of the liquid guide tube 66, and the inner cavity of the connecting cylinder 6451 is communicated with the inner cavities of both the graduated cylinder two 641 and the liquid guide tube 66. A pull plate 6452 fixedly connected to the lower end of the limiting rod 644 is arranged in the lower part of the inner cavity of the connecting cylinder 6451. A plurality of liquid discharge holes are longitudinally formed through the upper end of the pull plate 6452. A second spring 6455 fixedly connected to the bottom wall of the inner cavity of the connecting cylinder 6451 is arranged on the outer side of the lower end of the pull plate 6452. A second deformation ring 6456 fixedly connected to the bottom wall of the inner cavity of the connecting cylinder 6451 is arranged on the inner side of the lower end of the pull plate 6452. A sealing block 6457 is arranged in the middle of the lower end of the pull plate 6452. The sealing block 6457 is adapted to be used with the connection hole in the lower part of the connecting cylinder 6451 for communicating with the liquid guide tube 66. An installation tube 6453 is arranged on one side of the upper part of the connecting cylinder 6451 close to the liquid storage barrel 4. A sealing ring 6454 adapted to be used with the installation tube 6453 is arranged at the upper end of the pull plate 6452. [[ID=~14]] [[ID=~15]]

[0038] Further, the inner cavity of the installation pipe 6453 is also connected to the lower part of the inner cavity of the liquid storage barrel 4 through an infusion pipe.

[0039] Specifically, during the process that the piston 642 moves upward to suck the reagent in the inner cavity of the liquid storage barrel 4 into the inner cavity of the second measuring cylinder 641, the reagent in the inner cavity of the liquid storage barrel 4 enters the inner cavity of the connecting cylinder 6451 through the installation pipe 6453, and then the reagent enters the inner cavity of the second measuring cylinder 641 through the connection hole between the connecting cylinder 6451 and the second measuring cylinder 641. During this process, the sealing ring 6454 is located below the installation pipe 6453, and during this process, the sealing block 6457 blocks the connection hole where the connecting cylinder 6451 communicates with the liquid guiding pipe 66, preventing the reagent from flowing into the inner cavity of the liquid guiding pipe 66.

[0040] Further, after sucking the corresponding volume of reagent, when the limit rod 644 is pulled upward, the limit rod 644 will drive the pull plate 6452 to move upward, causing the pull plate 6452 to drive the sealing ring 6454 to move upward, and further causing the pull plate 6452 to block the installation pipe 6453, preventing the reagent from flowing back into the inner cavity of the liquid storage barrel 4 through the installation pipe 6453 during the process of guiding the reagent in the inner cavity of the second measuring cylinder 641 into the inner cavity of the liquid guiding pipe 66 later, which affects the accuracy of sucking the reagent.

[0041] Further, during the process that the pull plate 6452 moves upward, it will also drive the sealing block 6457 to move upward, and further cause the sealing block 6457 to no longer block the connection hole between the connecting cylinder 6451 and the liquid guiding pipe 66. Then when the staff pushes the lifting plate 65 downward, the piston 642 pushes the reagent in the inner cavity of the second measuring cylinder 641 into the inner cavity of the connecting cylinder 6451. The reagent entering the inner cavity of the connecting cylinder 6451 is introduced into the inner cavity of the liquid guiding pipe 66 through the liquid discharge hole at the upper end of the pull plate 6452. Then the liquid guiding pipe 66 introduces the reagent into the vessel placed in the inner cavity of the placement frame 63.

[0042] Further, when the pull plate 6452 moves upward, it will drive the second spring 6455 to stretch. When the staff has introduced all the reagent in the inner cavity of the second measuring cylinder 641 into the corresponding vessel, the staff no longer applies force to the limit rod 644. At this time, the second spring 6455 can pull the pull plate 6452 back to the initial position.

[0043] Further, the function and structure of the second deformation ring 6456 are the same as those of the first deformation ring 55.

[0044] During the daily use of the reagent dosage monitoring device, in order to adjust the height of the liquid guiding pipe 66, so that the liquid guiding pipe 66 can introduce the reagent into vessels at different heights, to prevent the reagent from splashing when it contacts the vessel when introducing the reagent into some vessels with a lower height because the position of the liquid guiding pipe 66 is relatively high, such as Figure 7As shown, positioning holes 611 are formed on both sides of the outer surface of the support frame 61 , and limiting holes are formed in an array in the middle of the two positioning holes 611 .

[0045] Further, such as Figure 11 As shown, the positioning device 7 includes two armrests 71 and two transparent plastic rings 73, and the two transparent plastic rings 73 are respectively fixedly mounted on the upper and lower sides of the outer surface of the measuring cylinder 2 641, and the upper and lower ends of the two armrests 71 are provided with connecting rods 72. The four connecting rods 72 extend into the inner cavity of the support frame 61 at one end close to the liquid storage barrel 4 through the two positioning holes 611 respectively. The ends of the connecting rods 72 on the upper and lower sides close to the liquid storage barrel 4 are respectively fixedly connected to the outer surfaces of the two transparent plastic rings 73, and a positioning plate 74 is slidably mounted in the middle of the inner cavity of the two armrests 71. The two positioning plates 74 are provided with springs three fixedly connected to the inner cavity surfaces of the two armrests 71 at one end away from the liquid storage barrel 4, and the two positioning plates 74 are provided with positioning blocks 75 at one end close to the liquid storage barrel 4, and the two positioning blocks 75 are respectively adapted to the limiting holes in the middle of the positioning holes 611 for use.

[0046] Specifically, before placing the container containing the reagent into the inner cavity of the placement frame 63, the staff can hold the two armrests 71 tightly to move the two positioning plates 74 to the side away from the suction mechanism 64, and then the two positioning plates 74 respectively drive the two positioning blocks 75 to break contact with the inner cavity surface of the corresponding limiting hole in the middle of the positioning hole 611. At this time, the positioning block 75 no longer restricts the armrest 71, and then the staff can adjust the height of the armrest 71 according to the height of the container containing the reagent, and then the armrest 71 drives the suction device 6 to move up and down through the connecting rod 72 and the transparent plastic ring 73, thereby adjusting the height of the liquid guide tube 66.

[0047] Furthermore, after the catheter 66 is adjusted to the corresponding height, the armrest 71 can be loosened. At this time, the spring three between the positioning plate 74 and the inner surface of the armrest 71 can push the positioning plate 74 back to the initial position, thereby allowing the two positioning blocks 75 to re-enter the inner cavity of the corresponding limiting hole, so that the positioning blocks 75 can restrict the armrest 71 again, thereby allowing the positioning device 7 to restrict the suction device 6 again.
