[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described below.

[0022] The present invention provides a handheld device with a throat sampling force detection function, comprising a handheld housing 1, a force sensor 2, a throat swab fixing tube 3, a signal board 4 and a power supply 5;

[0023] In this embodiment, if Figure 1As shown, the handheld shell 1 is a gun-shaped handheld shell 1, one end of the handheld shell 1 is used to plug in the throat sampling stick 12, and the end opposite to the throat sampling stick is a gripping portion; the handheld shell 1 is made of 3D printed surface sterilization material as a whole, which effectively prevents the internal sensors and parts from being impacted by external physical forces, and prevents the sensors from being affected by humidity and temperature, and prevents germs from entering the terminal.

[0024] In this embodiment, the force sensor 2 is fixed in the handheld housing 1 through the chassis 6. The chassis 6 is an octagonal part. One side of the chassis 6 is fixedly connected to the inner wall of the handheld housing 1 through bolts, and is specifically fixed inside the housing facing the grip portion. The chassis 6 of this embodiment is mainly fixed by bolts, the force sensor 2 and the housing. According to actual needs, the force sensor 2 and the chassis 6 can also be fixed by gluing; Figure 2 As shown, eight bolt holes are respectively provided on the upper and lower surfaces of the chassis 6 , four of which are located on the front for connecting with the inner wall of the handheld housing 1 , and the other four are located on the back for connecting with the bottoms of the four force sensors 2 one by one.

[0025] like Figure 2 As shown, the force sensor 2 is a 16mm*6mm*19mm cuboid. Two 16*6 faces each have a threaded hole for fixing the force sensor 2. The force sensor 2 is fixed to the chassis 6 with screws. The data lines of each force sensor 2 are connected to the signal board 4, and the signal board 4 is fixed next to the switch.

[0026] In this embodiment, if Figure 2 As shown, the throat swab fixing tube 3 is connected to four force sensors 2 through a conical cross base to achieve the transmission of detection force. The throat swab fixing tube 3 is located at the end of the handheld shell 1.

[0027] The conical cross base is an integrated hollow structure for 3D printing. The hollow structure reduces the material consumption and printing cost. The conical cross base includes a cross base 7, four support arms 8 and a reinforcing rib plate 9; the four legs of the cross base 7 are each connected to a force sensor 2, and the four legs of the cross base 7 are each connected to a support arm 8. The ends of the four support arms 8 converge at the throat swab fixing tube 3, which is used to fix the throat swab fixing tube 3, thereby forming a similar conical structure. The reinforcing rib plate 9 is connected to the middle of the four support arms 8; it plays a fixing role to ensure the firmness of the internal structure. The throat swab fixing tube 3 is connected to the inside of the conical cross base until the surface of the reinforcing rib plate 9. The diameter of the throat swab fixing tube 3 is the same as the diameter of the throat sampling stick, and the bottom of the throat sampling stick is inserted into the surface of the reinforcing rib plate 9 at most.

[0028] In this embodiment, a camera 10 and a lighting lamp are also included; a through hole for fixing the camera 10 and the lighting lamp is provided on the handheld housing 1, so that the camera 10 and the lighting lamp are arranged directly opposite the throat swab; the camera 10 and the lighting lamp are electrically connected to the power supply 5, and are connected to the signal board 4 through a wire. The camera 10 is used to collect the throat sampling images, and the lighting lamp facilitates the use of the device at night.

[0029] In this embodiment, an inertial measurement unit 11 (IMU) is also included. The inertial measurement unit 11 is arranged in the handheld housing 1, and is electrically connected to the power supply 5 and is signal-connected to the signal board 4. The inertial measurement unit 11 is used to sense the speed and angular direction of the robot when it is swallowing, so as to ensure the swallowing quality of the robot.

[0030] The specific use of the present invention is: the medical staff inserts the handheld device for grip force detection and correction, and the data of the force sensor 2 is returned to the computer. The computer calculates according to the real-time returned data and manipulates the mechanical arm to complete the nucleic acid swallowing test.
