Collecting barrel for various specifications of trace blood-collecting tubes

Abstract

The invention provides a collecting barrel for various specifications of trace blood-collecting tubes. The collecting barrel comprises a barrel body; an inner barrel is nested inside the barrel body;space between the inner barrel and the inner wall of the barrel body is divided evenly into at least three receiving chambers; the upper portion of the inner barrel is provided a first through holes in the barrel body, which correspond to the receiving chambers respectively; the part, close to the inner barrel, of each receiving chamber is provided with a second through hole, the part, close to the inner barrel, of the top of each receiving chamber is provided with a third through hole, third through holes face the second through holes, and a push component is inserted into the third and second through holes; each of the upper and lower portions of each receiving chamber is provided with an elastic component; each elastic component includes an elastic strap, a strap slider and a pull cord;each elastic strap corresponds to one trace blood-collecting tube; the middle of the outer side of the top of the barrel body is provided with an air balloon tube which is communicated with the inside of the inner barrel through a fifth through hole; the fifth through hole is arranged in the part, facing the inner barrel, of the barrel body, and a push component is inserted into the fifth throughhole. The collecting barrel is suitable for providing various specifications of trace blood-collecting tubes, so that good convenience of use is brought to medical personnel.

Description

technical field [0001] The invention relates to the technical field of micro-volume blood collection tubes, in particular to a collection tube of micro-volume blood collection tubes of different specifications. Background technique [0002] At present, if the red suction tip and micro blood collection pipette used for capillary blood collection are improperly used and the suction tip is accidentally released, all the blood collected by the micro blood collection pipette will be sucked into the suction tip. Due to the shape of the suction tip, After blood enters the tip, it will be difficult to clean the tip, and at the same time, it will cause blood pollution, and it cannot be used continuously. It is necessary to replace the micro blood collection tube for collection, which increases the workload of medical staff to a certain extent and brings resources. Waste, but if the suction head is not used, it is inconvenient for the medical staff to transfer the blood in the micro b...

[0002] At present, if the red suction tip and micro blood collection pipette used for capillary blood collection are improperly used and the suction tip is accidentally released, all the blood collected by the micro blood collection pipette will be sucked into the suction tip. Due to the shape of the suction tip, After blood enters the tip, it will be difficult to clean the tip, and at the same time, it will cause blood pollution, and it cannot be used continuously. It is necessary to replace the micro blood collection tube for collection, which increases the workload of medical staff to a certain extent and brings resources. Waste, but if the suction head is not used, it is inconvenient for the medical staff to transfer the blood in the micro blood collection straw into the bullet for storage. The switching of micro blood collection straws will bring inconvenience to medical staff to a certain extent
