For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0026] Please refer to Figures 1 to 4 The utility model provides technical scheme: a kind of device suitable for measuring tumor volume, including measuring cylinder 2, placing cylinder 1, the middle part side wall of measuring cylinder 2 is fixedly connected with communicating pipe 3, the end of communicating pipe 3 away from measuring cylinder 2 is fixedly connected with placing cylinder 1, and the both ends of communicating pipe 3 are communicated with measuring cylinder 2, placing cylinder 1 respectively, communicating pipe 3 is inclined to be arranged, and the end of communicating pipe 3 close to placing cylinder 1 is higher.

[0027] Among them, the device suitable for measuring tumor volume shown in the utility model is used to measure the volume of tumor separated from patient's body after operation. The upper end (i.e. inflow end) of communicating pipe 3 is communicated with the middle part of placing cylinder 1, and the lower end (i.e. outflow end) of communicating pipe 3 is communicated with the middle part of measuring cylinder 2, and the upper end of communicating pipe 3 is higher than the lower end. When measuring the volume of tumor separated from body, first pour clean water into placing cylinder 1, the liquid level in placing cylinder 1 is flush with the upper end port (port low point position) of communicating pipe 3, submerge tumor in water in placing cylinder 1, the liquid level in placing cylinder 1 is lifted, and the lifted part of liquid flows into measuring cylinder 2 through communicating pipe 3, and the volume of water flowed into measuring cylinder 2 is tumor volume, so as to realize the measurement of tumor volume.

[0028] The inner bottom wall of the placing cylinder 1 is provided with a clamping component, which comprises a gas cylinder 6, a circular plate 7, and a plurality of limiting assemblies. The circular plate 7 is fixedly installed at the output shaft end of the gas cylinder 6, and a plurality of sunken grooves 8 are arranged on the circumferential edge of the circular plate 7.

[0029] The clamping component is used to submerge the tumor in the water in the placing cylinder 1. The clamping component is waterproof. The gas cylinder 6 is used to drive the circular plate 7 to ascend and descend, and to drive the arc-shaped rods 9 in the limiting assemblies to change angles. After the angles of the arc-shaped rods 9 change, the tumor can be gripped and limited, that is, the tumor can be limited. When measuring the volume of the tumor in vitro, first, pour clean water into the placing cylinder 1, submerge the clamping component in the water, and make the liquid level in the placing cylinder 1 flush with the upper end port of the connecting pipe 3. Then, use the gas cylinder 6 to push the circular plate 7 to rise out of the liquid level, place the tumor on the circular plate 7, lower the gas cylinder 6 and drive the limiting assemblies to clamp the tumor, and submerge the tumor in the water by the clamping component. The volume of the clamping component in the water does not change before and after (specifically, the liquid level in the placing cylinder 1 does not rise during the ascending and descending of the gas cylinder 6). After the tumor is submerged in the water, the liquid level in the placing cylinder 1 is lifted, the water discharged due to the submersion of the tumor in the water flows into the measuring cylinder 2 through the connecting pipe 3, so as to realize the measurement of the volume of the tumor by measuring the volume of the discharged water, and realize the accurate measurement of the volume of the tumor.

[0032] Wherein, the cylinder 6 starts, the output shaft of cylinder 6 drives the circular plate 7 to rise, the circular plate 7 rises and pushes the lower end of arc-shaped rod 9 to move up, because the middle outer wall of arc-shaped rod 9 is hinged with spring rod 10, arc-shaped rod 9 is pulled by spring rod 10 to unfold.When each arc-shaped rod 9 unfolds, the tumor is placed on the circular plate 7.The output shaft of cylinder 6 drives the circular plate 7 to descend, the circular plate 7 descends and pushes the lower end of arc-shaped rod 9 to descend, arc-shaped rod 9 resets under the push of spring rod 10, so that each arc-shaped rod 9 in the limiting assembly resets, each arc-shaped rod 9 clamps and fixes the tumor, the output shaft of cylinder 6 drives the circular plate 7 to descend and immerse in water, because the tumor is fixed by each arc-shaped rod 9, the tumor is also immersed in water.When the clamping part resets completely, the volume of the clamping part in water is always unchanged before and after the action, so that the liquid level in the placing cylinder 1 is unchanged before and after.When the clamping part fixes the tumor in water, the tumor is immersed in water as a whole, and the liquid level in the placing cylinder 1 rises, the water body flows into the measuring cylinder 2 through the communication pipe 3, and the water level in the measuring cylinder 2 is measured, so that the tumor volume is measured.

[0033] Specifically, the bottom wall of the placing cylinder 1 is provided with a first liquid discharge pipe 4, and the first liquid discharge pipe 4 is provided with a first control valve.

[0034] Wherein, the first liquid discharge pipe 4 is used to discharge the water in the placing cylinder 1 after measuring the tumor volume, and the first control valve is used to control the on-off of the first liquid discharge pipe 4.

[0035] Specifically, the bottom wall of the measuring cylinder 2 is provided with a second liquid discharge pipe 5, and the second liquid discharge pipe 5 is provided with a second control valve.

[0036] Wherein, the second liquid discharge pipe 5 is used to discharge the water in the measuring cylinder 2 after measuring the tumor volume, and the second control valve is used to control the on-off of the second liquid discharge pipe 5.

[0037] Specifically, the outer side wall of the measuring cylinder 2 is engraved with a scale value mark line, and the upper end port of the measuring cylinder 2 is provided with a drying fan 12.

[0038] Wherein, the upper end port of the measuring cylinder 2 is in an open state, so as to avoid affecting ventilation. The drying fan 12 is a small fan, which is used for drying the moisture in the measuring cylinder 2, so as to prevent the measuring data from being affected by the residual moisture in the measuring cylinder 2.

[0039] Specifically, the communication pipe 3 is provided with a third control valve.

[0040] Wherein, the third control valve is used to control the on-off of the communication pipe 3.

[0041] Each control valve in the utility model can adopt an electromagnetic valve.

[0042] In use, first, water is poured into the placing cylinder 1, and the third control valve in the communicating pipe 3 is opened, so that the water level reaches the upper end port of the communicating pipe 3 and flows from the communicating pipe 3 into the measuring cylinder 2, then the water adding is stopped, and the third control valve on the communicating pipe 3 is closed. Then the second control valve in the second liquid discharge pipe 5 is opened, the liquid in the measuring cylinder 2 is discharged, and the drying fan 12 is opened to dry the measuring cylinder 2, so as to avoid the influence of residual liquid on the measurement result.

[0043] Then the measurement is carried out, in the measurement, the cylinder 6 is first elongated, the cylinder 6 drives the circular plate 7 to move upward, the lower end of the spring rod 10 is pulled by the connecting rod 11 and cannot move upward, so that the arc-shaped rod 9 rotates outward until the arc-shaped rod 9 is fully opened, the lower end of the arc-shaped rod 9 is blocked by the sinking groove 8 and cannot rotate, at this time, the cylinder 6 continues to rise, so that the spring rod 10 is stretched, until the circular plate 7 moves out of the water surface, then the tumor to be measured is placed on the circular plate 7, then the output shaft of the cylinder 6 is slowly contracted, so as to pull the circular plate 7 to move downward, in the process, the spring rod 10 is reset and drives the arc-shaped rod 9 to rotate upward, so as to surround the tumor, avoiding the tumor floating on the water surface, because the circular plate 7 is slowly lowered, the water surface is slightly disturbed.

[0044] After the tumor is immersed in the water, the water flows into the measuring cylinder 2 through the communicating pipe 3, and the volume of the tumor can be determined according to the water level in the measuring cylinder 2.

[0045] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the application concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
