Description

Test tube shaker

technical field

The utility model relates to a medical device, in particular to a test tube shaker device for helping the blood sampled test tubes to be shaken evenly after the blood is collected in a hospital outpatient clinic.

Background technique

The flow of people in major hospitals in our country is very large. The nurses in the outpatient blood drawing room of the hospital have to collect thousands of people every day. Each blood collection test tube must be shaken to prevent blood coagulation. The workload is very high. Some test tubes that are not shaken well in time will cause blood coagulation; ERS and other anticoagulant tubes are thinner, and the slow shaking speed will also cause blood coagulation; and the manual vibration force of nurses is too strong, which will cause blood cell damage and affect the results. And shaking the test tube while taking blood is very time-consuming and affects work efficiency. Once the blood coagulation in the blood collection test tube occurs, it is necessary to call the patient to recall the blood collection again, which will add trouble and pain to the patient, affect diagnosis and treatment, easily cause medical disputes, delay operation time and other problems.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

As shown in Figure 1-9, the utility model is a test tube shaking device, which includes an electric support part 1 and a disc-shaped test tube wheel frame 2; the electric support part 1 includes a base 11 that can be placed horizontally on the desktop , the support 12 standing on one side of the top of the base 11, the base 11 and the support 12 are L-shaped as a whole (as shown in Figure 3 ), and the side of the support 12 facing the inner side of the L-shape is connected with the base 11. Rotating rotating shaft 13, the section of described rotating shaft 13 is cross-shaped, is provided with motor in described base 11 and can drive rotating shaft 13 to rotate, is provided with the button 14 that can start motor on the side of support 12 facing L-shaped outside; Press The button 14 can make the motor drive the rotating shaft 13 to rotate.

The middle part of the test tube rack 2 is provided with a cross-shaped rotating shaft socket 21 that runs through the axis of the test tube rack. The rotating shaft 13 can be inserted into the rotating shaft socket 21 on the test tube rack 2. , because the section of the rotating shaft 13 is cross-shaped, so the test tube rack 2 and the rotating shaft 13 are circumferentially fixed, so that the rotation of the rotating shaft 13 can drive the test tube rack 2 to rotate, and the test tube rack 2 is evenly provided with a plurality of test tube mounting tubes 22 along the circumference , the blood collection test tube can be inserted into the test tube installation cylinder 22, and the test tube installation cylinder 22 extends radially along the test tube wheel frame 2, and the mouth of the test tube installation cylinder 22 is provided with an annular elastic rubber ring, so that the blood collection test tube and the test tube installation cylinder 22 tightly fits the socket, and will not fall out during the rotation of the test tube installation cylinder 22.

In order to axially fix the test tube rack 2 on the rotating shaft 13, the rotating shaft 13 is provided with an elastic bayonet 131 of metal ring structure that can be retracted or ejected to the outer surface of the rotating shaft 13, preferably the elastic bayonet 131 is located at the turning point of the rotating shaft 13 close to the center of the axis (as shown in Figure 6), and a slot-shaped bayonet slot 211 corresponding to the position of the elastic bayonet 131 and having a suitable shape is provided in the shaft socket 21 (as shown in Figure 7 As shown), when the elastic bayonet 131 snaps into the bayonet slot 211, the test tube wheel frame 2 is axially fixed on the rotating shaft 13, and the test tube wheel frame 2 directly slides on the rotating shaft 13 during installation so that the elastic bayonet 131 snaps into the card Notch 211, need to press bayonet key 121 when taking down test tube wheel frame 2, described bayonet key 121 is positioned on the side of support 12 away from rotating shaft 13, and is positioned on the central axis of rotating shaft 13.
