The weight sensing unit 20 can refer to the "drip flow detection warning device" of No. M445446, which is a technical means that must be achieved.

The movable structure 32 includes a pressing member 321, an auxiliary member 322, and an elastic member 323. The pressing member 321 is in contact with the infusion hose 91 and is configured to move relative to the space 30A, and the infusion hose 91 can be relaxed and pressurized, and the infusion hose 91 is relaxed (as shown in FIG. 3A). ), the flow rate of the infusion hose 91 can be increased, and when the pressure is changed (for example, from FIG. 3B to FIG. 3C), the infusion hose 91 can reduce the guide of the infusion hose 91. flow.

Thereby, when the driving element 331 controls the rotation of the cam 332, the cam top abutting surface 33A is used to adjust the pressing member 321 to loosen and pressurize the infusion hose 91.

For example, when the cam 332 is rotated to the original angle θ, the infusion hose 12 has a first infusion width D1 (as shown in FIG. 3A); when the cam 332 is rotated to the first change angle θ 1 (as shown in FIG. 3B), the infusion hose 12 has a second infusion width D2 which is smaller than the first infusion width D1; and when the cam 332 is rotated to the second variation angle θ 2 (eg, As shown in Fig. 3C, the infusion hose 12 has a third infusion width D3 which is less than the second infusion width D2.

The monitoring unit 40 can be at least one of a computer host, a tablet computer, and a mobile phone.

When it is a computer host, the display interface 43 can be a screen. The control interface 44 can be at least one of a keyboard, a mouse, and an associated input device.

When at least one of a tablet computer and a mobile phone is used, the display interface 43 and the control interface 44 are integrated into a touch screen.

The portion to be specifically described herein is the position of the third wireless transmission structure 41, the central processing unit 42, the display interface 43, and the control interface 44 on the monitoring unit 40 in each of the drawings. It can be changed according to the actual use requirements and the design of the circuit, and it is not limited to a fixed position.

In fact, the invention is mainly applied to two levels:

[a] External drainage of the brain: Referring to Figure 4, one end of the infusion hose 12 is located in the patient's cranium (this is a well-known medical technique, not a patent claim in this case, and will not be described), and the other end passes through the space. After 30A, the liquid accommodating portion 11 is connected to start the "intraventricular drainage". The part to be specifically described here is that if the drainage speed of "intraventricular drainage" is too fast, it may cause concurrent cerebral palsy or cerebral ventricle bleeding. Therefore, it is necessary to periodically check (preferably monitor) the drainage condition, and the third radio transmission structure 41 of the monitoring unit 40 wirelessly receives the weight signal W; and the central processing unit 43 retrieves the weight The signal signal W is converted into the instantaneous flow rate value F and displayed on the display interface 43 for the caregiver to monitor the patient's drainage speed in real time.

For example, it is assumed that the liquid accommodating portion 11 and the weight sensing structure 21 have a first distance H1 (as shown in FIG. 5A) and is increased to a second distance H2 during the draining process (as shown in FIG. 5B). As shown in the figure), if the instantaneous flow rate value F is too large, the control signal S can be output through the control interface 44 (for example, the downward arrow shown in FIG. 2), and transmitted to the flow rate through the third wireless transmission structure 41. The adjusting portion 30 is configured to slow down (can be slowed down, and can also be adapted to special medical requirements, and can be adjusted to increase the flow rate of the infusion hose 91).

[b] drip infusion control: Referring to Fig. 6, one end of the infusion hose 12 is used for infusion of a patient (this is a well-known technique in medicine, not a patent claim in this case, and will not be described), and the other end passes through the After the space 30A, the liquid accommodating portion 11 (in this case, a drip bottle) is connected. Similarly, the third radio transmission structure 41 of the monitoring unit 40 wirelessly receives the weight signal W; and the central processing unit The weight signal W is taken and converted into an instantaneous flow rate value F and displayed on the display interface 43 for the caregiver to monitor the drip infusion speed of the patient at a distance.

For example, it is assumed that the liquid accommodating portion 11 and the weight sensing structure 21 have a first distance HA (as shown in FIG. 7A) and is reduced to a second distance HB during the infusion process (eg, FIG. 7B). As shown, when the caregiver monitors that the instantaneous flow rate value F is too large, the control signal S can be output through the control interface 44 (for example, the downward arrow shown in FIG. 2) and transmitted through the third wireless transmission structure 41. To the flow rate adjusting portion 30, the flow rate of the infusion hose 91 is slowed down (can be slowed down, and can be adjusted to meet special medical requirements).

The advantages and functions of the present invention are as follows:

[1] Integrated monitoring input and output drainage is quite convenient. In the medical treatment process, input drainage and output drainage are also important steps in medical treatment. The invention can be used for monitoring input drainage or output drainage, and is beneficial to the integration of medical treatment equipment, for example, point liquid infusion (input drainage) and Extracorporeal drainage (Output drainage) The device of the present invention can also be used in the same manner, so it is quite convenient to integrate the monitoring input drain and the output drain.

[2] Remote monitoring facilitates the care of medical staff. As far as the current medical system is concerned, it is usually a nursing staff who must care for multiple patients. The invention can be used for long-distance monitoring, which can help the nursing staff to carry out simple dressing care for the patient A, and maintain the remote monitoring of the severely drained B patient by using a wireless communication device such as a tablet or a mobile phone. Effectively improve nursing work. Therefore, remote monitoring facilitates the care of medical staff.

[3] Remote control drainage facilitates the care of medical staff. It is assumed that the same nursing staff is in the medical care of the patient A, and the instantaneous flow value of the input and drainage of the patient B is found to be too slow, and the instantaneous flow value of the output of the patient is found to be too fast. At this time, it is not necessary to immediately drop the patient A, and then rush to the B and C patients for infusion adjustment, and directly through the control interface, control the input and drainage of the B patient to speed up, and control the input drainage of the C patient to slow down, which is quite convenient. Therefore, remote control drainage facilitates the care of medical staff.

[4] Intelligent drainage is quite unique. The invention can be an intelligent device which has both induction, automatic data generation and remote control drainage speed. Therefore, intelligent drainage is quite unique.

The present invention has been described in detail with reference to the preferred embodiments of the present invention, without departing from the spirit and scope of the invention.
