Background

The sample transmission system starts to be applied in hospitals and receives good reflection, and the test tubes are transmitted in the closed pipeline at high speed through the pressure air, so that the major problem of the hospitals is solved. The transmission after the sample is collected is an important link in the whole process of sample inspection, a one-to-one transmission mode is mostly adopted for a sample transmission device, the sample transmission device is designed to be used between each large blood sampling point and an inspection department in a hospital, the samples in hospital departments, high-quality wards and some emergency wards need to be manually transmitted, the transmission mode can not only keep up with the requirements of the development concept of the hospital, but also is not safe, the time is life, the rapid result output is realized by pumping, the requirement of the high-speed development of the modern hospital is also the greatest respect and love for the patient, the sample sending device can be used for a nurse station in the nurse department and also can be used for the heating outpatient service, the nucleic acid test tube is transmitted by adopting a closed special pipeline, the rapid result output is convenient, and the sample sending device is expected by each large hospital.

A rotation type multi-pipeline sample sending mechanism is used for directly sending a sample to remote detection equipment by a subdividing pipeline after the sample is sorted in multiple categories, and is a one-to-many sample transmission solution. The specimen transmission is different from other material transmission essentially, and single test tubes enter special closed pipelines in a front-back sequence to keep relative distance for transmission, so that the specimens in operation need to be prevented from colliding and vibrating each other. The sample transmission system adopting single-pipeline transmission meets the requirement of transmission quantity in peak periods, transmission density is as high as possible, the distance between the sample and the sample in the pipeline cannot be pulled, the number of times of collision of the sample in the pipeline is increased, and the quality of a sensitive blood sample is damaged. The sample is classified firstly and then is classified and transmitted by multiple pipelines, so that the sample interval of each entering pipeline is ensured to be as far as possible, the collision probability in the operation process is greatly reduced, the sample transmission efficiency is greatly improved, the device is the most favorable solution device in the blood sampling peak period of the great three hospitals, and the safe and quick blood sample transmission to the inspection device is the most care and responsibility for patients. Another important reason for the multi-channel transportation after the classification is adopted is that the blood sample needs to be kept still before the on-machine test, and the blood sample is kept still for a certain time depending on the type of the blood sample, so that all blood samples cannot be classified and kept still at present. The method is the most scientific solution for automatic mechanical testing after classification and standing, and is the requirement of accurate testing. The mechanism not only meets the requirement of safe transmission in peak periods, but also realizes the requirement of classified standing, realizes the function of directly and automatically conveying the blood to various types of test machine equipment from the blood sampling window in a classified manner, and has higher intelligent level and more obvious efficiency. The multi-pipeline sending is adopted, so that the sample can be sent to a plurality of target receiving stations at the same time to realize the shunt operation, the high-efficiency device can realize the delivery of the sample in a limited time, the resource sharing of hospital inspection equipment is realized, the resource utilization rate is improved to the maximum extent, and the method is also the optimal scheme for finally implementing the full-automatic on-computer test.

the device is provided with five transmission pipelines 29, each transmission pipeline 29 corresponds to one category, the category of a specimen A and the serial number of the pipe hole are bound when the specimen A enters a specimen storage pipe hole 210 in a multi-port rotating body 21, the multi-port rotating body 21 rotates according to the sequence of the pipe holes, the specimen A can stop instantly entering and striking out of the rotating body when passing through a specimen output port 250, when the category of the specimen in the specimen storage pipe hole 210 is the same as the specimen transmission category of the specimen output port 250, a corresponding electromagnetic valve on an input cover plate 23 is opened, compressed air instantly enters a striking port, the specimen A is immediately blown out of the specimen storage pipe hole 210 and enters the transmission pipeline 29 of the corresponding category, the category of the transmission pipeline 29 is immediately opened after the process is finished, the compressed air for transmission enters from a compressed air inlet 257 of a pipeline interface of an output port cover plate 25, and the specimen A entering the transmission pipeline 29 starts to rapidly move towards a receiving station under the action of the compressed air The compressed air for transmission is opened until no specimen exists in the transmission pipeline 29, the beating air valve and the transmission air valve are opened and closed alternately, the transmission air valve is closed instantly when the beating air valve is opened, and otherwise, the beating air valve is closed. When the samples of a plurality of categories correspond to the outlet pipe ports of the same category at the same time, the plurality of striking electromagnetic valves are opened at the same time, and when no sample a of the same category corresponds to the outlet pipe 29 when the multi-port rotating body 21 rotates by one frame, the striking electromagnetic valves are not opened. After completion of one rotation cycle, the specimens in the multi-port rotating body 21 should be completely emptied, the memory of the control circuit is restarted from zero, and a new round of specimen sending control is started.
