Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an alarm device with drainage tube flow rate monitoring after surgical operations. Background Art

[0002] Surgeons are most afraid of postoperative bleeding, especially cardiac surgeons. Due to the particularity of cardiac surgery, postoperative bleeding and drainage are more serious, which has become the most feared thing after surgery.

[0003] Commonly used drainage devices include negative pressure drainage bags, negative pressure drainage devices, negative pressure drainage bottles, etc. During drainage, medical staff usually monitor the drainage manually, and the medical staff observes the drainage based on experience.

[0004] However, in actual operation, medical staff cannot perform monitoring work for a long time and cannot effectively monitor whether the drainage fluid is flowing out normally. Therefore, in the face of excessive drainage, the timing of secondary thoracotomy to stop bleeding is particularly critical. In many cases, missing the opportunity leads to pericardial tamponade, unstable circulation, organ failure, and irreversible consequences for patients.

[0005] At present, the clinically recognized indications for secondary thoracotomy in cardiac surgery are 500 ml / h in 1 hour, more than 300 ml / h in 2 hours, more than 200 ml / h in 3 hours, or 150-200 ml / h in 4 hours, 50-100 ml / h in 12 hours (total amount > 2 000 ml), etc. These are all indications for secondary thoracotomy to stop bleeding.

[0006] Timely judging the drainage volume during cardiac surgery and determining whether a second thoracotomy is necessary to stop bleeding are of great significance for minimizing damage to the patient. Therefore, a medical drainage tube flow rate monitoring alarm is needed to improve the above problems. It is particularly important to invent an alarm device with drainage tube flow rate monitoring after cardiac surgery. Summary of the invention

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Figure 1 The schematic diagram of an alarm device with drainage tube flow rate monitoring after surgical operation according to a preferred embodiment of the present invention is schematically shown.

[0032] like Figure 1As shown, in one embodiment of the present invention, the alarm device with drainage tube flow rate monitoring after surgical operation includes: a shell 10 attached to the body of the drainage tube 100, a color sensor 20 carried by the shell 10 (for example, the back of the shell 10 carries the color sensor 20, but the color sensor 20 can be at any appropriate position of the shell 10, as long as it can detect the liquid in the body of the drainage tube 100 attached between the upper clamp-shaped ring 30 and the lower clamp-shaped ring 40) and a computing unit (not shown). In fact, the computing unit can be arranged at any position); wherein the color sensor 20 is configured with an upper clamping ring 30 and a lower clamping ring 40, and the body of the drainage tube 100 is clamped by the upper clamping ring 30 and the lower clamping ring 40, so that the liquid (specifically, blood or body fluid containing blood) in the part of the body of the drainage tube 100 attached between the upper clamping ring 30 and the lower clamping ring 40 flows into drops or lines (for example, 5 drops are controlled to be 1 ml).

[0033] Among them, the main body of the shell 10 and the body of the drainage tube 100 can be directly and tightly attached to the body of the drainage tube 100, and the two can be abutted; or the main body of the shell 10 can be located on one side of the body of the drainage tube 100, and a certain gap is left between the two (the two ends of the main body of the shell 10 are attached to the tube body through the upper clamping ring 30 and the lower clamping ring 40), which is not limited here.

[0034] Particularly advantageously, the upper clamping ring 30 and the lower clamping ring 40 clamp the body of the drainage tube 100 so that the liquid in the tube portion between the upper clamping ring 30 and the lower clamping ring 40 is formed into droplets of uniform size.

[0035] In this embodiment, the color sensor 20 monitors the dripping rate or flow rate of the drop-shaped or line-shaped liquid in the tube body portion between the upper clamping ring 30 and the lower clamping ring 40, and the calculation unit is electrically connected to the color sensor 20 and is used to calculate the liquid flow rate in the tube body according to the dripping rate or flow rate monitored by the color sensor 20.

[0036] It can be understood that the present invention provides an alarm device with drainage tube flow rate monitoring after surgical operations. While the color sensor 20 is attached to the tube body of the drainage tube 100 through the upper clamping ring 30 and the lower clamping ring 40, the flow rate of the intermediate liquid is controlled by clamping the upper and lower parts, so that the color sensor 20 can monitor the liquid dripping speed between the two clamping parts, thereby further calculating the flow rate of liquid such as blood, so as to monitor postoperative bleeding in time.

[0037] In one embodiment of the present invention, the alarm device with drainage tube flow rate monitoring after surgical operation also includes: an alarm unit, which is electrically connected to the calculation unit; wherein the color sensor 20 causes the alarm unit to alarm when the monitored dripping rate exceeds the predetermined dripping rate range, or the calculation unit causes the alarm unit to alarm when the calculated liquid flow rate exceeds the predetermined flow rate range.

[0038] In one embodiment of the present invention, Figure 4 As shown, the portion of the drainage tube 100 between the upper clamp-like ring 30 and the lower clamp-like ring 40 may be formed as an expanded portion 11 .

[0039] Preferably, the upper clamp-shaped ring member 30 and the lower clamp-shaped ring member 40 are adjustable ring clamps composed of a screw and a screw. For example, the upper and lower ends of the housing of the color sensor 20 are both designed with a clamp-shaped screw. By screwing the upper or lower clamps, respectively adjusting, the diameter of the two ends of the drainage tube 100 can be controlled, so that the blood flows into the expanded part 11 of the drainage tube 100 between the clamps in a drop shape or a line shape.

[0040] It can be seen that the color sensor 20 is mounted on the drainage tube 100 by clamping. At this time, the drainage tube 100 is fixed by the ring-shaped clamp which can be adjusted up and down, and the color sensor 20 is also fixed. This structure is very convenient for loading and unloading.

[0041] In the specific example of monitoring blood flow rate, for example, the color sensor 20 is a red sensor. Therefore, in the present invention, the speed (dripping speed) of red blood passing through is sensed by the color sensor 20 and converted into an electrical signal and transmitted to the calculation unit, and then the drainage volume per unit time is calculated by the calculation unit.

[0042] like Figure 2 As shown, in one embodiment of the present invention, the alarm device with drainage tube flow rate monitoring after surgical operation also includes: a display screen 50, wherein the display screen 50 is arranged in the housing of the color sensor 20 or is separately arranged from the color sensor 20, and the display screen 50 is electrically connected to the calculation unit and is used to display the calculation results of the calculation unit.

[0043] In one embodiment of the present invention, an adjustment button for adjusting monitoring parameters is provided on the housing of the color sensor 20. The monitoring time and the set value of the monitoring can be set by the adjustment button. When the drainage liquid flow rate is greater than 500 ml / h in 1 hour (i.e., the average flow rate in 1 hour is greater than 500 ml / h), 300 ml / h in 2 hours, 200 ml / h in 3 hours, or 150-200 ml / h per hour in 4 hours, and 50-100 ml / h in 12 hours, an alarm will be issued, which can effectively remind medical staff to deal with it in time at any time.

[0044] Figure 1 and Figure 2 The schematic diagram shows the case where the color sensor 20 is arranged on the side of the expanded portion 11 of the drainage tube 100. In other specific embodiments, as shown in FIG. Figure 3 As shown, for example, the expanded portion 11 of the drainage tube 100 can be closely attached to (embedded in) the housing 10 of the color sensor 20. Specifically, for example, the expanded portion 11 of the drainage tube 100 is closely attached to (embedded in) an adjustable open half tunnel 21 (i.e., as shown in FIG. 1 ) that runs through the housing of the color sensor 20. Figure 3 As shown, the cross section of the half tunnel 21 is arc-shaped, and one outer wall of the shell is cut off by the tunnel), and for example, a slot 22 can be configured in the adjustable open half tunnel 21, and the upper and lower ends of the slot 22 can be respectively provided with an upper clamping ring 30 and a lower clamping ring 40.

[0045] For example, the clamp-shaped ring is designed as an adjustable clamp-shaped screw, one end of the screw extends to the inside of the slot, and the other end of each screw is fixedly connected to a knob, so that the drainage tube 100 can be tightened and fixed to prevent it from falling. At the same time, the diameter of the two ends of the drainage tube 100 can be controlled to make the blood drop-shaped or line-shaped, which is convenient for the color sensor 20 to sense and calculate the drainage volume per unit time.

[0046] In addition, although Figure 1 and Figure 2 The diagram schematically shows a situation where the color sensor 20 is clamped and fixed to the expansion portion 11 of the drainage tube 100 by two clamps, an upper clamp ring 30 and a lower clamp ring 40, and the flow rate is controlled. In other specific embodiments, only one clamp may be used to clamp and fix the color sensor 20 to the tube body of the drainage tube 100 and control the flow rate.

[0047] For example, Figure 4 As shown, the present invention also proposes an alarm device with drainage tube flow rate monitoring after surgical operation, comprising: a shell 10 attached to the tube body of the drainage tube 100, a color sensor 20 carried on the back of the shell, and a calculation unit; wherein the drainage tube 100 is formed with an expansion portion 11, the color sensor 20 is configured with a clamping ring 60, and is clamped to the upper end of the expansion portion 11 by the clamping ring 60, so that the liquid flowing into the expansion portion 11 is formed into a drop shape or a line shape; and, the color sensor 20 monitors the dripping rate or flow rate of the drop-shaped or line-shaped liquid in the expansion portion 11, and the calculation unit calculates the liquid flow rate in the tube body according to the dripping rate or flow rate monitored by the color sensor 20.

[0048] certainly, Figures 1 to 3 The improvement of the embodiment is also applicable to Figure 4 The embodiment shown.

[0049] In addition, it should be noted that, unless otherwise specified, the terms "first", "second", "third", etc. in the specification are only used to distinguish the various components, elements, steps, etc. in the specification, and are not used to indicate the logical relationship or sequential relationship between the various components, elements, steps, etc.

[0050] It is to be understood that, although the present invention has been disclosed as a preferred embodiment, the above embodiment is not intended to limit the present invention. For any person skilled in the art, without departing from the scope of the technical solution of the present invention, the technical content disclosed above can be used to make many possible changes and modifications to the technical solution of the present invention, or modified into equivalent embodiments of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of protection of the technical solution of the present invention.
