Description

Technical Field

[0001] The invention relates to a blood sampling test tube sorting device, belonging to the field of medical equipment. Background Art

[0002] As the public's awareness of medical and health care gradually increases, the requirements for medical care quality also increase. It is conducive to the reasonable arrangement and optimization of hospital personnel and improving the work efficiency of medical staff has become the focus of the development of medical and health care. This is an opportunity to promote and improve medical machinery, and it is also a basic requirement for promoting the automation process in the medical field and realizing machine replacement.

[0003] At present, when medical institutions diagnose and treat patients who need blood samples for analysis, they generally use test tubes to load and store these samples. Due to different test items, different types of test tubes need to be marked and labeled. However, hospitals still rely on manual operations in a series of operations such as test tube storage, differentiation, and labeling, which is a waste of human resources. When the flow of patients is too large, the workload of medical staff increases, and the phenomenon of wrong labeling and missing labeling occurs. To improve this situation, many hospitals have begun to introduce test tube transportation and labeling equipment.

[0004] As labeling machines continue to be put into the market, the operating speed and accuracy of medical staff have been greatly improved. However, the existing test tube conveyor has very limited space for storing test tubes, and there is no clear classification of test tube types. Most of the different types of test tubes use one machine for each type of test tube, which takes up a lot of space. When medical staff are overloaded, it is unavoidable to take the wrong thing, which is easy to make mistakes. Based on the above problems, it has become a necessary requirement to design a device to solve the problems of test tube classification, screening and retrieval. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a fully automatic selection and transportation mechanism for blood collection tubes to achieve a series of actions such as classified storage, arrangement, automatic selection, and transportation of blood collection tubes.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A fully automatic blood collection tube selection and transportation mechanism, comprising a storage tank rotation mechanism, a position adjustment mechanism, a plug-in reciprocating motion mechanism and a transportation mechanism, wherein the plug-in reciprocating motion mechanism is located at the center of the storage outer tank, and the transportation mechanism is located below the whole machine;

[0008] The storage tank rotation mechanism includes a copper column, a bearing turntable, an external gear, an internal gear, an external storage tank, a partition, a cylinder, a synchronous belt, a rotary motor, a small pulley, a large pulley and a shaft. The external gear and the internal gear mesh with each other. The external gear is fixed to the bearing turntable. The outer ring of the bearing turntable is fixedly installed on the aluminum profile. The rotary motor drives the internal gear to rotate through a synchronous belt pulley. The internal gear is coaxially installed with the large pulley. The external storage tank is installed on the external gear through a stud and rotates with the external gear. The partition equally divides the external storage tank. The partition fits with the conical baffle on the plug plate movement mechanism. The cylinder is embedded with the partition.

[0009] The position adjustment mechanism includes a steering gear and a scraper. The scraper is fixed to the steering gear by screws. The bottom of the external storage tank has threaded holes. The steering gear is installed at the bottom of the storage external tank by screws.

[0010] Furthermore, the plug plate reciprocating movement mechanism includes a support plate, a conical baffle, a first plug plate, a second plug plate, a chute, a guide groove, two first driving motors, a lead screw, an inclined plate and a first driving motor bracket. The first driving motor is installed on the first driving motor bracket by bolts. The first driving motor bracket is fixed to the inclined plate. The two ends of the hinge are respectively connected to the lead screw and the first plug plate or the second plug plate. The two first driving motors respectively control the alternating movement of the first plug plate and the second plug plate.

[0011] Preferably, the angle of the inclined plate is 60°.

[0012] Still further, the transportation mechanism includes a second driving motor, a vertical bearing seat, a conveyor belt, a second coupling and a conveyor belt pulley. One end of the shaft of the second driving motor is fixed to one end of the second coupling by screws. The other end of the second coupling is fixed to the conveyor belt pulley. The conveyor belt is installed on the two conveyor belt pulleys at both ends.

[0013] The beneficial effects of the present invention are mainly manifested in that: through the information of the patient's blood sample to be tested collected by the computer, different types of test tubes are automatically selected, and then transmitted to the labeling machine through the conveying mechanism, the labels are printed, and finally transmitted to the hands of medical staff. In this process, medical staff only need to check the number of test tubes and replenish them regularly, which effectively reduces the errors of manual sorting and greatly improves the efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Refer to Figures 1 to 10 , a fully automatic selection and conveying mechanism for blood collection test tubes, including a storage tank rotation mechanism, a position adjustment mechanism, a reciprocating movement mechanism of a plug board, and a conveying mechanism. The fully automatic selection and conveying mechanism for blood collection test tubes includes a base 1, a copper column 2, a support plate 3, a bearing turntable 4, an external gear 5, a servo motor 6, a storage outer tank 7, a second driving motor 8, a motor bracket 9, a second coupling 10, a vertical bearing seat 11, a conveyor belt wheel 12, a lead screw nut 13, a hinge 14, a conveyor belt 15, a small belt wheel 16, a synchronous belt 17, a rotation motor 18, a large belt wheel 19, a shaft 20, a lead screw 21, an inclined plate 22, a guide groove 23, a plug board one 24, a plug board two 25, a conical baffle 26, a chute 27, a small gear 28, a partition board 29, a scraper 30, a cylinder 31, and a first driving motor bracket 32.

[0026] The storage tank rotating mechanism includes a copper column 2, a bearing turntable 4, an outer gear 5, an inner gear 28, a storage outer tank 7, a partition 29, a cylinder 31, a synchronous belt 17, a rotating motor 18, a small pulley 16, a large pulley 19 and a shaft 20. The outer ring of the bearing turntable 4 is connected to one end of the copper column 2 by screws, and the other end of the copper column 2 is fixed on the aluminum profile. The inner ring of the bearing turntable is fixed to the outer gear 5 just above the turntable by screws and copper columns, and the small gear 28 is meshed with the outer gear. The rotating motor 18 drives the small gear 28 to rotate through the synchronous pulley, and the small gear is coaxially installed with the large pulley 19. A threaded hole is opened at the bottom of the storage outer tank 7, which is screwed to one end of the copper column, and the other end of the copper column is installed above the outer gear. Because the storage outer tank 7, the outer gear 5, and the inner ring of the bearing turntable are connected together, the rotation angular velocity and direction are consistent, and the outer ring of the bearing turntable is fixed. The partition 29 divides the storage outer tank 7 into six equal parts, and the partition fits the conical baffle 26 on the plug-in plate movement mechanism. The cylinder 31 is embedded in the partition, leaving a gap with the bottom of the storage outer tank, and the gap distance is 1-2 test tube widths. The function of the cylinder is to separate the test tube from the conical baffle and the plug-in plate to prevent the test tubes in the tank from piling up too high and affecting the up and down lifting of the plug-in plate.

[0027] The position adjustment mechanism includes a steering gear 6 and a scraper 30. The scraper 30 is fixed to the steering gear 6 by screws. The bottom of the storage outer tank 7 has a threaded hole. The steering gear 6 is installed at the bottom of the storage outer tank by screws. The scraper 30 swings left and right to move the test tube to enter the lifting track of the plug board 1 to prevent the test tube from being retained in the tank.

[0028] The plug-in plate reciprocating motion mechanism comprises a support plate 3, a conical baffle plate 26, a plug-in plate 1 24, a plug-in plate 25, a slide groove 27, a guide groove 23, a first drive motor, a screw rod 21, an inclined plate 22, a motor bracket 9, and a guide groove 23. The conical baffle plate 26 is connected to the support plate 3 by screws, and the support plate 3 is fixed to the aluminum profile. The first drive motor is installed on the first drive motor bracket 32 by bolts, and the first drive motor bracket 32 is fixed to the inclined plate, and the inclined plate angle is about 60°. The two ends of the first coupling are respectively connected to the first drive motor drive shaft and the screw rod 21, and there is a screw rod nut 13 on the screw rod. The two ends of the hinge 14 are respectively connected to the screw rod nut and the plug-in plate 1 24 or the plug-in plate 25 by bolts. When the first drive motor is running, the screw rod converts the rotation into the linear motion of the plug-in plate 1 and the plug-in plate 2 through the screw rod nut and the hinge. A first drive motor controls the first plug plate to lift to the limit position ①, which is also the lowest point of the second plug plate. Then another first drive motor controls the second plug plate to lift to the limit position ②, and the test tube is transported to the guide groove. The two plug plates are tilted at an angle of 15°. This tilt angle is designed to prevent the test tube from leaving the moving track, so that the test tube can roll from the first plug plate to the second plug plate, and then be transported from the second plug plate to the guide groove. The guide groove sends the test tube to the conveyor belt.

[0029] The transport mechanism is a conveyor belt group composed of a second drive motor 8, a second coupling 10, a vertical bearing block 11, a conveyor belt pulley 12, and a conveyor belt 15. One end of the second drive motor shaft is fixed to one end of the second coupling by screws, the other end of the second coupling is fixed to the conveyor belt pulley, and the conveyor belt is installed on the conveyor belt pulleys at both ends. The transport mechanism conveys the test tubes that slide down the guiding groove to the labeling machine.

[0030] The above specific implementation manners are used to explain the present invention rather than limit the present invention. Any modifications and changes made to the present invention within the spirit and scope of the claims of the present invention fall within the protection scope of the present invention.
