Problems solved by technology

[0002] Pipettes and pipettes are essential instruments and equipment for the CDC and hospital laboratories when performing sample pipetting operations. The tightness of the liquid gun prevents contamination of the pipette, but this type of pipette and the pipettes currently on the market do not take into account that the pipette is prone to falling off during the use of the pipette, especially When a medical institution pipettes a sample with a blood virus, such as the HIV virus, if the pipette falls off and the blood sample splashes from the pipette, once the medical practitioner has a wound on the body and touches the splashed sample, there will be Infection risk, there is no cure for these blood-borne diseases, and the consequences are extremely serious, so in view of the above problems, the present invention designs an improved medical pipette

Embodiment 1

[0021] refer to Figure 1 to Figure 4 , the pipette gun includes a gun body 1 and a pipette 6, the edge of the gun body 1 is provided with a cavity 2, and the gun head 3 at the bottom of the gun body 1 is provided with an annular cavity 4 communicating with the cavity 2, and the bottom of the gun head 3 Connecting head 5 is provided at the end, and annular cavity 4 is also opened in connecting head 5, and the surface of connecting head 5 is provided with vent hole 51 and annular cavity 4 communicates, and connecting head 5 is covered with pipette 6, and pipette 6 is glued with a silicone pad 61 at the junction of the connector 5 .

[0022] Gun body 1 is provided with piston hole 7 and communicates with cavity 2 near the edge of cavity 2, and piston hole 7 is offered as several, and piston block 8 is arranged in piston hole 7, and one end of piston block 8 is fixedly connected with spring 81, and spring 81 is fixedly connected to the bottom wall of the cavity 2 at one end away...

Embodiment 2

[0027] refer to Figure 5 to Figure 7 The difference between the present embodiment and the first embodiment is that, after the single pipetting process is completed, it is convenient to disengage the pipette 6 from the connector 5, and a pipe holder 11 is set on the surface of the gun body 1, and the pipette is opened. The pipe frame 11 includes a connecting ring 111 and a support frame 112. The connecting ring 111 is attached to the surface of the gun body 1. The connecting ring 111 is provided with a support frame 112. One end of the support frame 112 is fixedly connected with the push button 12. The support frame 112 is far away from the pressing button. One end of the key 12 is fixedly connected to the pipe block 113, and the pipe block 113 is arranged on both sides of the connector 5, and the key 12 is pressed to be fixedly connected to a slide block 121. In the groove, and the slide block 121 is fixedly connected with the bottom wall of the groove with a spring, by pres...

Abstract

The invention discloses an improved medical pipette gun which comprises a gun body and a pipette. A cavity is formed in the edge of the gun body, and an annular cavity is formed in the gun head at thebottom end of the gun body and is communicated with the cavity. A connector is arranged at the bottom end of the gun head, an annular cavity is also formed in the connector, a vent hole is formed inthe surface of the connector and is communicated with the annular cavity, the connector is sleeved with the pipette, and a silica gel pad adheres to the joint of the pipette and the connector. A piston hole is formed in the portion, close to the cavity, of the gun body and communicated with the cavity; a piston block is arranged in the piston hole, one end of the piston block is fixedly connectedwith a spring, and a piston rod is fixedly connected with the end, away from the spring, of the piston block; the end, away from the piston block, of the piston rod penetrates through the piston holeand is fixedly connected with a handle. The situation that the pipette falls off in the liquid conveying process is effectively prevented, the safety of medical workers is effectively protected, the pipette can be knocked out through a tube beating frame, the operation is convenient, and the operation efficiency is improved.
