Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1 to 4.
The sampling tube comprises a sampling tube 1, wherein the front end of the sampling tube 1 is fixedly connected with an air sac ball 2, the rear end of the sampling tube 1 is fixedly connected with an air sac 3, a drainage tube 4 is sleeved in the sampling tube 1, the front end of the drainage tube 4 is positioned outside the sampling tube 1, a drainage hole 5 is formed in the front side of the drainage tube 4, a piston cylinder 6 is sleeved on the rear sides of the drainage tube 4 and the sampling tube 1 together, and a piston rod 7 capable of sliding back and forth is connected in the piston cylinder 6 in a sliding mode.
The sampling tube 1 and the drainage tube 4 are both made of PVC materials, so that the sampling tube 1 and the drainage tube 4 have certain hardness, the sampling tube 1 can be conveniently inserted into the body of a patient, when the sampling tube 1 enters the body of the patient, the air sac ball 2 is in a shriveled state, the resistance of the air sac ball 2 when the sampling tube 1 enters the body is reduced, after the sampling tube 1 enters the body of the patient, the air sac ball 2 can be pressed to increase the volume of the air sac ball 2, the air sac ball 2 is in contact with body fluid in the body of the patient to collect a sample, the device reduces the inflated air sac ball 2 in order to reduce the discomfort of the patient, meanwhile, in order to ensure the amount of the sample, a sampling person can move rightwards relative to the piston tube 6 by controlling the piston rod 7, so that negative pressure is formed in the piston tube 6, and some body fluid in the body of the patient is absorbed into the piston tube 6 through the drainage tube 4 and the drainage hole 5, ensuring the extraction amount of the sample.
The piston rod 7 is in an n-shaped shape placed on the side, a fixed block 8 fixedly connected with the piston cylinder 6 is connected onto the piston rod 7 in a sliding mode, a handle 9 is fixedly connected to the other end of the piston rod 7, and a spring 10 is sleeved on the piston rod 7 between the handle 9 and the fixed block 8; the handle 9 is rotatably connected with a pull ring 11, and the pull ring 11 is matched with a cylindrical rod 12 fixedly connected with the fixed block 8.
The handle 9 and the pull ring 11 are located on the upper side of the piston cylinder 6, the handle 9 and the balloon 3 are located on the same side of the device, so that a patient can conveniently control the handle 9 and the balloon 3, as shown in fig. 2, when the handle 9 is pushed to move towards the right, the handle 9 drives the piston rod 7 to move towards the right along the fixed block 8 and the piston cylinder 6, and meanwhile, the spring 10 on the piston rod 7 is compressed, when the handle 9 moves to the rightmost position, the pull ring 11 can be rotated to sleeve the pull ring 11 on the cylindrical rod 12, so that the situation that the spring 10 pushes the piston rod 7 to rebound is avoided, and at the moment, the negative pressure in the piston cylinder 6 sucks body fluid in the patient; after the body fluid sample is extracted, the pull ring 11 can be taken down from the cylindrical rod 12, and the piston rod 7 pushes out the liquid in the piston cylinder 6 under the action of the spring 10, so that the medical personnel can extract the sample conveniently, and the working efficiency is improved.
The bottom of the piston cylinder 6 is fixedly connected with a rubber ring 13.
The upper side wall of the piston cylinder 6 is provided with scale marks 14.
The scale lines 14 are volume lines and are provided with volume readings around the scale lines, so that the operator can know the extraction amount of the sample conveniently.
The sampling device is novel in structure, ingenious in conception and simple and convenient to operate, and the problems that sampling samples are reduced and fall off due to too few air bags in the existing sampling device, and the body of a patient is uncomfortable due to convergence of the air bag ball 2 process are effectively solved through the design.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
