Abstract
The invention discloses a portable color Doppler ultrasound instrument capable of effectively reducing weight, and relates to medical instruments. The track device comprises a mounting seat and is characterized in that a hollow track ball is placed in the mounting seat and can freely rotate in the mounting seat; a counterweight iron bead is also arranged inside the hollow track ball; the mounting seat is provided with a magnetic attraction mechanism at the lower position of the hollow track ball. The hollow track ball is adopted to replace the traditional solid track ball, so that the overall weight can be reduced. Meanwhile, due to the matching of the internal counterweight iron beads and the magnetic attraction mechanism, the enough rotation stability between the track ball and the mounting seat can be still kept, and the drifting phenomenon can not occur. Most importantly, the weight is reduced, the consistent use habit of medical care is not changed, the appearance structure is not changed at all, and the medical care stable use is guaranteed.
Description
Technical Field
The invention relates to medical instruments, in particular to a portable color Doppler ultrasound instrument capable of effectively reducing weight.
Background
The portable color ultrasound instrument is originally designed to facilitate medical care and can effectively and timely carry out color ultrasound examination on patients during outwork. Therefore, the portable color ultrasound instrument has special research and development requirements for weight, miniaturization and the like, wherein the miniaturization research is most common in the prior art, but the portable color ultrasound instrument is only designed aiming at light weight and has little significance.
It is more difficult to design lightweight without changing the original functions or affecting the medical working habits. As shown in fig. 1-3, a conventional portable color ultrasound apparatus is provided with a track device 10 at a lower position in the keyboard. The function and the working principle of the mouse are similar to those of a mouse, and the mouse can facilitate medical care to adjust the image condition at any time, adjust the coordinate position and the like. The track device 10 mainly comprises a mounting seat 11 and a solid track ball 12, wherein the solid track ball 12 is placed inside the mounting seat 11, and the upper part of the solid track ball protrudes out for the rotation of a human hand. When the solid track ball 12 rotates in the mounting seat 11, the track can be captured by the sensing element arranged in the mounting seat 11, so that human-computer interaction is realized. The solid track ball 12 is set to have a large weight so as to be able to stably rotate in the mounting seat 11 without drifting, and is one of the weight sources of the portable color ultrasonic instrument.
Disclosure of Invention
The invention aims to provide a portable color Doppler ultrasound instrument with effectively reduced weight so as to solve the problems in the prior art.
The invention relates to a portable color Doppler ultrasound instrument capable of effectively reducing weight, which comprises a track device arranged below the middle part of a keyboard, wherein the track device comprises a mounting seat; a counterweight iron bead is also arranged inside the hollow track ball; the mounting seat is provided with a magnetic attraction mechanism below the hollow track ball.
The magnetic attraction mechanism is an electromagnetic coil, and the electromagnetic coil is electrically connected with a power supply of the portable color ultrasonic instrument.
The magnetic attraction mechanism is a permanent magnet.
The portable color Doppler ultrasound instrument capable of effectively reducing the weight has the advantages that the hollow track ball is adopted to replace the conventional solid track ball, so that the overall weight can be reduced. Meanwhile, due to the matching of the internal counterweight iron beads and the magnetic attraction mechanism, the enough rotation stability between the track ball and the mounting seat can be still kept, and the drifting phenomenon can not occur. Most importantly, the weight is reduced, the consistent use habit of medical care is not changed, the appearance structure is not changed at all, and the medical care stable use is guaranteed.

Detailed Description
The portable color Doppler ultrasound instrument capable of effectively reducing weight comprises a display screen, a keyboard, a track device 10, a power supply, an ultrasonic probe and the like. Wherein the track device 10 is arranged at a position below the middle part of the keyboard, close to one side of the human body. As shown in fig. 4, the track device 10 includes a mounting seat 11 and a hollow track ball 13 disposed in the mounting seat 11. The upper part of the hollow track ball 13 protrudes above the mounting seat 11, and the appearance of the color ultrasonic instrument is not different from that of the prior art. A free rolling counterweight iron bead 14 is arranged inside the hollow track ball 13, the counterweight iron bead 14 does not need to have too large mass, and the pressure applied to the hollow track ball 13 mainly comes from a magnetic attraction mechanism 15 outside the hollow track ball 13. The magnetic attraction mechanism 15 is arranged in the mounting seat 11 and is positioned right below the hollow track ball 13.
The magnetic attraction mechanism 15 can be a permanent magnet or an electromagnetic coil. If the permanent magnet is used, the magnetic attraction mechanism 15 only needs to be fixedly installed in the installation seat 11. The magnetic attraction mechanism 15 can automatically attract the counterweight iron ball 14, so that the counterweight iron ball 14 always presses the hollow track ball 13 to the magnetic attraction mechanism 15 to replace the original gravity-dependent condition of the track ball. Compared with the electromagnetic coil, the permanent magnet has the advantages of no need of additional circuit improvement and simple structure.
If the magnetic attraction mechanism 15 is an electromagnetic coil, the magnetic attraction mechanism 15 needs to be connected to a power supply, and the power supply provides a stable magnetic field to attract the counterweight iron beads 14. For the permanent magnet, solenoid's advantage lies in that weight can be lighter, and the dynamics of inhaling moreover can be adjusted through the size of electric power, has more nimble adjustability.
Therefore, the portable color Doppler ultrasound machine can effectively reduce the overall arrangement without changing the original operation habit of medical care, and better meets the portable design requirement. Moreover, the rolling stability does not depend on the weight of the original track ball any more, but depends on the magnetic attraction. The rolling stability can be further improved by increasing the magnetic attraction force while the weight is reduced.
It will be apparent to those skilled in the art that various other changes and modifications may be made in the above-described embodiments and concepts and all such changes and modifications are intended to be within the scope of the appended claims.
