Description

Technical Field

[0001] The present invention relates to the technical field of hospital inspection, and specifically to a sampling device for a hospital inspection department. Background Art

[0002] In the field of medical inspection, the collection and processing of blood samples in the hospital inspection department are crucial links. Although existing blood sampling devices can meet the basic blood collection requirements in terms of design and function, there are still many deficiencies in actual use, which affect the efficiency and accuracy of the blood collection and detection processes.

[0003] Currently, some traditional blood sampling devices only have a single blood collection function, such as the technical content disclosed in a venous therapy nursing blood sampling device for cyclic blood collection with the publication number [CN116649974A]. This sampling device mainly consists of a tube body and a blood collection needle, and blood is drawn through a blood collection tube connected by a piston. However, this device has obvious limitations.

[0004] First, during the blood collection process, this device cannot perform shunt processing on the drawn blood. When multiple tests need to be performed on a patient, medical staff have to perform multiple blood collection operations, which not only increases the pain and inconvenience of the patient, but also may cause the patient to have emotions such as nervousness and fear due to multiple blood collections, affecting the smooth progress of the blood collection work. Moreover, multiple blood collections will consume more time, reduce the blood collection efficiency, slow down the preparation progress of the test samples, and thus affect the efficiency of the entire detection process.

[0005] Second, the sampling device in this comparative document has defects in the storage and sealing of blood samples. It does not have a dedicated component for shunt collection and sealing of blood samples, and the blood samples can only be centrally stored in one container after collection. During storage, due to the lack of effective fixing and sealing measures, the blood samples are easily interfered by external factors, such as the intrusion of air, dust, microorganisms, etc., which can change the composition and properties of the blood samples, reducing the quality of the blood samples. This will not only affect the accuracy of the test results, but also may lead to waste of samples and increase medical costs.

[0006] Third, this device lacks necessary protection mechanisms during operation. For example, for the key components that control blood shunting, no protection measures are set, and medical staff may inadvertently touch the relevant components during operation due to busyness, limited operation space, etc., resulting in the shunting components shaking, shifting, or even blood samples spilling out, destroying the normal storage state of the samples and affecting the smooth progress of the subsequent detection process.

[0007] In addition, the sampling device of this comparative document has an unreasonable structural design, and the cooperation between components is poor. For example, during the blood shunting and sealing processes, the operation of each component is not convenient enough, increasing the operation difficulty and work intensity of medical staff. Moreover, the detachability and cleaning convenience of the device are insufficient, which is not conducive to later maintenance and cleaning, and is prone to bacterial growth, further affecting the safety of blood samples and the accuracy of test results.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 10As shown in the figure, a sampling device for a hospital laboratory includes a tube body 1. A blood collection needle 2 is fixedly installed at the top of the tube body 1. A blood collection tube 3 is connected to a piston inside the tube body 1. A flow splitting mechanism 4 for splitting the blood extraction is arranged inside the tube body 1. The flow splitting mechanism 4 includes a movable part and a fixed part. The fixed part fixes the movable part and splits and collects the extracted blood. A protection component 5 is used to seal the blood after flow splitting and collection.

[0035] In this embodiment, the movable part includes a connecting pipe 41. The connecting pipe 41 is fixedly installed on the surface of the tube body 1. A flow splitting pipe 42 penetrates through the inside of the connecting pipe 41. A flow splitting block 43 is installed outside the blood collection tube 3. The flow splitting block 43 is slidably connected to the inner wall of the tube body 1. By sliding the flow splitting block 43 inside the tube body 1, the blood sample can be split into the inside of the flow splitting pipe 42 for storage, reducing the number of blood collections for patients, accelerating the preparation progress of the test samples, and improving the efficiency of the blood collection and testing process.

[0036] Furthermore, a first chute 10 is opened inside the tube body 1, a first groove 11 is opened at the bottom of the tube body 1, a second groove 12 is opened on the inner side of the tube body 1. The first groove 11 communicates with the second groove 12. A first square groove 430 is opened at the bottom of the flow splitting block 43, a second square groove 431 is opened on the outer side of the flow splitting block 43, a semi-circular groove 420 is opened on the inner side of the flow splitting pipe 42, and a card slot 421 is opened on the surface of the flow splitting pipe 42. By means of the semi-circular groove 420 opened on the inner side of the flow splitting pipe 42, it can be realized that when the flow splitting pipe 42 is installed inside the tube body 1, it will not be restricted by the blood collection tube 3.

[0037] Even further, the fixed part includes a fixing ring 44. The fixing ring 44 is fixedly installed on the surface of the connecting pipe 41. A turntable 45 is rotatably connected inside the fixing ring 44. A control block 46 is fixedly installed on the surface of the turntable 45. The control block 46 is slidably connected to the inside of the fixing ring 44. A slide bar 47 is slidably connected to the surface of the turntable 45. A clamping block 48 is fixedly installed at the top of the slide bar 47. A sliding bar 49 is fixedly installed at the top of the clamping block 48. A fixing strip 410 is fixedly installed inside the fixing ring 44. The sliding bar 49 is slidably connected to the inside of the fixing strip 410. By using the clamping block 48 to restrict the card slot 421 opened on the surface of the flow splitting pipe 42, the stability and fixing effect of the flow splitting pipe 42 during use can be realized.

[0038] In addition, the fixed part further includes an anti-touch part. The anti-touch part includes a positioning block 411. The positioning block 411 is fixedly installed on the surface of the connecting pipe 41. A protection block 412 is slidably connected inside the positioning block 411. A fixing spring 413 is fixedly installed inside the protection block 412. The fixing spring 413 is fixedly installed inside the positioning block 411. By means of the fixing spring 413 arranged at the bottom of the protection block 412, the effect of resetting the protection block 412 after it is released and pulled can be realized.

[0039] In addition, the protection component 5 includes a supporting block 51, which is fixedly installed on the surface of the blood collection tube 3. A sliding shaft 52 is slidably connected inside the shunt tube 42. A connecting block 53 is fixedly installed on the surface of the sliding shaft 52, and a reset spring 54 is fixedly installed inside the sliding shaft 52. The reset spring 54 is fixedly installed inside the shunt tube 42. The reset spring 54 provided on the surface of the sliding shaft 52 can achieve the effect of resetting when the connecting block 53 is released from the contact with the inner wall of the tube body 1.

[0040] It should be noted that a connecting rod 55 is fixedly installed at the top of the surface of the sliding shaft 52, and a sealing block 56 is fixedly installed at the top of the connecting rod 55. The sealing block 56 is slidably connected inside the shunt tube 42. An insertion rod 57 is fixedly installed outside the sealing block 56. The insertion rod 57 penetrates through the shunt tube 42. The insertion rod 57 outside the sealing block 56 can achieve the effect of facilitating the taking when the sealing block 56 seals the shunt tube 42.

[0041] It should be explained that a rectangular groove 450 is formed on the surface of the turntable 45. When the turntable 45 rotates, it can contact the sliding rod 47 and slide on the surface of the turntable 45 through the rectangular groove 450 formed on the surface of the turntable 45. A strip-shaped groove 4100 is formed on the surface of the fixing strip 410. When the turntable 45 rotates, it can drive the sliding rod 49 to slide inside the fixing strip 410 through the strip-shaped groove 4100 formed on the surface of the fixing strip 410. The cross-section of the connecting block 53 is conical. The conical connecting block 53 can improve the contact effect of the tube body 1 on the connecting block 53. The cross-section of the sealing block 56 is semi-circular. By combining the two sealing blocks 56, the center of the sealing block 56 is the center of the circle, and the blood collection tube 3 can slide inside the sealing block 56. There are two shunt tubes 42, and the two shunt tubes 42 are symmetrically arranged with the center line of the tube body 1 as the axis of symmetry. The two shunt tubes 42 can be used to store blood samples differently.

[0042] Working principle: when the sampling device for the hospital laboratory is used, the blood sampling effect of the patient's blood can be achieved by inserting the blood collection needle 2 into the patient's body and pulling the blood drawing tube 3 connected to the piston to slide downward inside the tube body 1. During sampling, the blood drawing tube 3 sliding downward will also drive the shunt block 43 to slide downward at the slide groove 10 opened inside the tube body 1. When the shunt block 43 moves, the patient's blood will also enter the inside of the shunt block 43 through the square groove 1 430 opened on the top of the shunt block 43. When the shunt block 43 slides downward, it is because the square groove 2 431 opened on the outside of the shunt block 43 fits on the inner wall of the tube body 1, thereby preventing blood from flowing out from the outside of the shunt block 43. When the shunt block 43 moves to the groove 11 opened on the inner side of the tube body 1, the square groove 2 431 opened on the outside of the shunt block 43 at this time will contact with the tube body 1. The groove 12 opened inside is connected, so that blood can flow out from the left and right sides of the shunt block 43 at the same time. Since the groove 11 inside the tube body 1 is connected to the groove 2 12, when the blood flows out from the left and right sides of the shunt block 43 at the same time, it will flow out from the inside of the tube body 1 to the inside of the two shunt tubes 42 for storage. The blood shunt can prevent medical staff from reducing the number of blood draws from patients when taking blood samples for different tests. The shunted blood can directly enter different shunt tubes 42. Medical staff can easily distribute each tube of blood to the corresponding test process, without the need for complicated manual separation, distribution and other preparations for the mixed blood samples, which speeds up the preparation of the test samples, saves the time cost of medical staff for multiple blood collection operations, and improves the efficiency of the blood collection and testing process.

[0043] When the shunt tube 42 is used to store the blood sample, the shunt tube 42 needs to be inserted into the tube body 1 first, and the turntable 45 is driven to rotate by manually sliding the control block 46. When the turntable 45 rotates, the rectangular groove 450 on its surface will contact the slide bar 47 to move toward the center point of the turntable 45. When the slide bar 47 moves, the slide bar 49 on the top of the block 48 will move inside the fixed bar 410 toward the inner side of the fixed bar 410. When the slide bar 47 and the slide bar 49 slide, they will drive the block 48 to move toward the center point of the shunt tube 42. The surface of 42 is swung, so that the clamping block 48 is clamped on the surface of the shunt tube 42 for fixation, and the shunt tube 42 can be released by the reverse sliding control block 46 to prevent the shunt tube 42 from shifting or even falling off due to unexpected situations such as shaking and collision during the storage of blood samples if it is not reliably fixed, causing the blood sample in the tube to spill out, causing sample waste and possibly polluting the surrounding environment. The detachable shunt tube 42 can also be used to facilitate the cleaning of the shunt tube 42 and the tube body 1 after use.

[0044] When the control block 46 needs to be moved and triggered, it is first necessary to manually slide the protective block 412 downward at the bottom of the positioning block 411 so that the control block 46 is exposed on the surface. When the medical staff has completed the operation of the control block 46, the restriction on the protective block 412 can be manually released. At this time, the protective block 412 will be reset under the action of the fixed spring 413, so that the protective block 412 is moved back to the surface of the control block 46 for protection, preventing the medical staff from accidentally touching the control block 46 due to being busy or having limited operating space, thereby causing the shunt tube 42 to shake, shift or even spill blood samples, thereby destroying the normal storage state of the samples and affecting the smooth progress of the subsequent detection process, thereby improving the accuracy and stability of the operation of the shunt tube 42.

[0045] When the shunt tube 42 is installed inside the tube body 1, the inner wall of the tube body 1 will resist the connecting block 53 set on the surface of the shunt tube 42, so that the sliding shaft 52 is driven by the connecting block 53 to move toward the inner side of the shunt tube 42, and when the sliding shaft 52 moves, the sealing block 56 is driven by the connecting rod 55 to slide in the same direction as the moving direction of the connecting rod 55, thereby achieving the effect of opening the shunt tube 42. After the shunt tube 42 has finished storing blood, the restriction of the shunt tube 42 by the card block 48 can be released first, so that the shunt tube 42 slides to Inside the support block 51, the inner wall of the tube body 1 will release the resistance to the connecting block 53, so that the sliding shaft 52 is reset under the action of the reset spring 54, and drives the connecting rod 55 and the sealing block 56 to reset, so that the sealing block 56 moves again to the surface of the shunt tube 42 for sealing, preventing the outside air, dust, microorganisms, etc. from easily entering the shunt tube 42 in an unsealed state, changing the composition and properties of the blood sample, reducing the possibility of blood sample leakage and contamination, improving the protection of the blood sample, and improving the accuracy of the test results.
