Detailed Description
As shown in fig. 1 to 6, the present invention mainly includes a sampling needle 1, a sampling tube 2, and a pressurizing mechanism, and the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the sampling needle 1 comprises a needle 11 and a hose 12 connected to the needle, and a handle 13 is provided on the needle to facilitate penetration of the needle into a blood vessel of a patient's arm. The hose is "Y" shape structure, and the first end of hose is connected with the syringe needle, and the second end and the third end of hose are branch pipe 14, are connected with sampling tube 2 on the branch pipe.
As shown in fig. 2 and 4, the sampling tube 2 includes a storage portion 21, an end cap 22 fixedly connected to the storage portion, an outer plug 23 communicated with the end cap, and an inner plug 25 disposed inside the outer plug, wherein the storage portion 21 is made of rubber, a first end of the storage portion is open, a second end of the storage portion is sealed, and the storage portion has a cylindrical structure after being supported. The end cap 22 is made of plastic, is cylindrical and is open at one end, and the open end of the storage part is sleeved on the open end of the end cap. The outer plug 23 is of a cylindrical structure and is fixedly connected with an end cover, and a through hole communicated with the inner cavity of the outer plug is formed in the end cover. The first end of the outer plug is open, the second end of the outer plug is provided with a mounting hole, the tail end of the branch pipe penetrates into the mounting hole, and the tail end of the branch pipe is relatively fixed with the outer plug. The connection firmness between the branch pipe and the outer plug is not strong, and the separation of the branch pipe and the outer plug can be realized under the action of human power and bare hands.
The end of the branch pipe is fixed with a protrusion 24, the protrusion is in a cylindrical structure, as shown in fig. 6, the whole inner plug is in a columnar shape, the first end of the inner plug is in a round table structure, the second end of the inner plug is in a cylindrical structure, a first hole 251 is formed in the end face of the first end of the inner plug, a second hole 252 is formed in the side wall of the first end of the inner plug, the first hole is communicated with the second hole, the first end of the inner plug is in contact with the end of the branch pipe, and the first hole on the inner plug is communicated with the inner cavity of the branch pipe. The liquid in the manifold may enter the first aperture, then the second aperture, and then the reservoir through the second aperture. A stop 253 is fixed at the second end of the inner plug, and the diameter of the stop is larger than that of the second end of the inner plug. The diameter of the second end of the inner plug is the same as the inner diameter of the mounting hole, the connection firmness between the branch pipe and the inner plug is stronger than the connection firmness between the branch pipe and the outer plug, so that when the branch pipe is pulled to one side far away from the outer plug, the tail end of the branch pipe can be separated from the outer plug, after the branch pipe is separated from the outer plug, the inner plug moves along with the branch pipe, at the moment, the first end of the inner plug firstly enters the mounting hole, and then the second end of the inner plug enters the mounting hole until the stop block 253 contacts with the inner wall of the outer plug. When the branch pipe is pulled again, the branch pipe is separated from the inner plug, the inner plug is plugged into the mounting hole, the outer plug is sealed with the mounting hole, the outer plug, the end cover and the storage part form a sealed sampling pipe, and blood samples in the sampling pipe cannot flow out. The projection may be in line contact with the second end of the outer plug and may be pulled off the outer plug before pulling the branch outwardly. Four groups of pull belts 26 are arranged on the outer wall of the storage part, two pull belts arranged in groups are axially arranged along the end cover, and the four groups of pull belts are uniformly arranged along the circumferential surface of the end cover.
In order to promote blood to flow into the sampling tube as soon as possible, a pressurizing mechanism is arranged on the outer side of the storage part, as shown in fig. 3 and 5, the pressurizing mechanism comprises a pressurizing plate 3 arranged on the outer side of the storage part, hooks 34 fixed on the inner wall of the pressurizing plate and corresponding to the pull belts one by one, the pressurizing plate is of a U-shaped structure with an opening facing the end cover, the pressurizing plate has elasticity, two ends of the opening side of the pressurizing plate are both fixed with lug plates 33, an inserting rod 31 is fixed on the lug plate above, an inserting hole 32 is fixed on the lug plate below, and after the inserting rod is inserted into the inserting hole, the pressurizing plate is of a conical structure, one end of the pressurizing plate facing the end cover is small, and one end of the pressurizing plate far away from the end cover is large. The hook is of an L-shaped structure, and the acting end of the hook penetrates into the drawstring, so that the hook is connected with the storage part. A cushion block 4 is plugged between the pressurizing plate and the storage part, and the cushion block can be sponge, cotton cloth and the like. And the cushion block is arranged, and the cushion block cooperates with the pressurizing plate to squeeze the storage part into a flat shape. . When the pressure plate is used, the cushion block is taken out from between the pressure plate and the storage part, then the inserting rod is pulled out from the inserting hole, the opening end of the pressure plate is opened under the action of self elasticity, and at the moment, the two ends of the opening side of the pressure plate are mutually far away. In the process, the hooks pull the pull belts to form an outward pulling effect on the side wall of the storage part, so that the storage part is changed from a flat shape into a full cylindrical shape as soon as possible, the speed of two blood entering the storage part is accelerated, and rapid blood sampling is realized. After blood collection, the pressurizing plate is detached from the storage part, and the sampling needle is separated from the sampling tube.
The invention has simple structure, can realize rapid collection of blood and shortens the waiting time of blood sampling of patients.
