In addition, the technical features described above in the different embodiments of the present utility model may be combined with each other as long as they do not collide with each other.

In order to solve the technical problems that in the prior art, a user cannot directly detect whether the purifying device 30 fails, waste is easily caused by periodic replacement, or replacement is not timely because the amount of liquid flowing through the purifying device 30 cannot be directly measured, the utility model provides a comprehensive treatment table waterway terminal purifying and detecting device, which can directly judge whether the purifying device 30 fails through the concentration of a sterilizing medium in the liquid flowing through the purifying device 30 so as to ensure that the liquid flowing out of a waterway meets the use requirement.

Referring to fig. 1, the purification and detection device for the waterway terminal of the comprehensive treatment table provided by the utility model comprises a buffer tube 10 and a detection assembly 20. The liquid flowing out of the waterway terminal enters the surgical instrument through the buffer tube 10, and the detection assembly 20 arranged on the buffer tube 10 can detect whether the liquid flowing out of the purifying device 30 meets the use requirement. Because the flow rate of the liquid in the waterway terminal of the comprehensive treatment table is relatively fast, the concentration detector 21 in the detection assembly 20 is unfavorable for detecting the content of the disinfection medium in the liquid, and therefore, the buffer tube 10 needs to be arranged to temporarily reduce the flow rate of the liquid, so that the concentration detector 21 is convenient for detecting the concentration of the disinfection medium.

Referring to fig. 3 and 4, specifically, the buffer tube 10 of the present utility model includes a bottom shell 11 and a cover 12, which together define a cavity. The buffer tube 10 in this embodiment is rectangular parallelepiped; the bottom shell 11 is in a rectangular box shape, one surface of the bottom shell is provided with an opening, the cover body 12 is plate-shaped, the whole opening can be completely covered, and the cover body 12 in the embodiment is square plate-shaped. The two ends of the buffer tube 10 are respectively provided with an inlet 14 and an outlet 15; an external water source, i.e. liquid flowing out of the purification device 30, enters the cavity from the inlet 14. The inlet 14 and the outlet 15 may be disposed at two ends of the bottom case 11, or the inlet 14 may be disposed at one end of the bottom case 11, the outlet 15 may be disposed at one end of the cover 12 facing away from the inlet 14, or the inlet 14 and the outlet 15 may be disposed at two ends of the cover 12. In the present embodiment, an arrangement is adopted in which the inlet 14 is provided on the bottom case 11, and the outlet 15 is provided on the cover 12.

It should be noted that the cross-sectional area of the cavity in the direction of the flow of the liquid is larger than the cross-sectional areas of the inlet 14 and the outlet 15. Thus, as liquid enters the chamber from the inlet 14, the flow rate of the liquid will decrease, which will facilitate the concentration detector 21 to measure the concentration of the sterilizing medium; as the liquid approaches the outlet 15, the liquid will again be accelerated so that the flow rate of the liquid meets the requirements of the treatment. Preferably, the cross-sectional area at the outlet 15 should be smaller than the cross-sectional area at the inlet 14 to compensate for the flow rate lost by the liquid flowing through the chamber.

Referring to fig. 3, a shunt device 13 is further disposed in the cavity of the present utility model, and the shunt device 13 is disposed on a surface of the bottom shell 11 facing the cover 12. The flow dividing device 13 in this embodiment includes at least two flow dividing columns, and the height of the flow dividing columns should not affect the assembly of the bottom shell 11 and the cover 12; of course, in some embodiments, the splitter device 13 may be formed by a splitter plate or a splitter plate combined with a splitter post. The flow dividing columns in this embodiment are cylindrical and uniformly arranged on the bottom shell 11, and the flow dividing device 13 can make the flow of the liquid in the buffer tube 10 more uniform, so that the concentration detector 21 can conveniently and accurately measure the concentration of the sterilizing medium in the liquid, and the sterilizing medium can also be conveniently and further mixed with the liquid, so that the liquid can obtain a better sterilizing effect.

Referring to fig. 2 to 4, in the present utility model, a sealing ring 40 is further disposed at a position where the cover 12 and the bottom shell 11 are connected. The sealing ring 40 can be a common rubber sealing ring 40, or can be replaced by waterproof glue 50. In the utility model, the edge of the opening of the bottom shell 11 is in a step shape, and the sealing ring 40 is arranged on the step. Correspondingly, a stepped bulge is also arranged on the side of the cover body 12 facing the bottom shell 11, so that the cover body 12 can be matched with the opening. The gasket 40 can fill the gap between the bottom shell 11 and the cover 12, thereby preventing leakage of the buffer tube 10 during use.

Referring to fig. 2, the detecting assembly 20 of the present utility model includes a concentration detector 21, a flow rate detector 22, and an alarm. The cover 12 is provided with the opening 16 matched with the probe of the concentration detector 21, and the probe is preferably arranged at the center of the cover 12, so that the concentration can be measured conveniently due to the slow liquid flow rate at the center of the cavity; the probe of the concentration detector 21 extends into the cavity through the opening 16, and a waterproof glue 50 is further arranged at the position where the opening 16 is connected with the probe, so that liquid leakage at the opening 16 can be prevented, and the concentration detector 21 can be fixed. The kind of concentration detector 21 should be compatible with the kind of disinfection medium in the purification device 30. For example, in the present embodiment, iodine ions are used as the sterilizing medium in the purifying device 30, and then the concentration detector 21 capable of measuring the concentration of iodine ions in the liquid should be selected.

Referring to fig. 4, since the outlet 15 in this embodiment is a circular hole, certain waterproofing and fixing measures, such as filling the waterproof glue 50, should be provided when connecting the outlet 15 with the water pipe of the surgical instrument.

Referring to fig. 2, the flow detector 22 is connected at both ends to the inlet 14 of the buffer tube 10 and an external fluid source, i.e., the purge device 30. The flow detector 22 can facilitate a medical professional to visually observe the amount of liquid filtered by the purification apparatus 30. Typically, the manufacturer will set a maximum amount of liquid that can be purified for the purification apparatus 30, and when the amount of liquid purified by the purification apparatus 30 exceeds this amount, it is recommended to replace the purification apparatus 30 in case the purification apparatus fails. Although the present utility model can determine whether the purifying apparatus 30 is out of order by the concentration detector 21, when the amount of the liquid filtered by the purifying apparatus 30 has exceeded the recommended value of the manufacturer, the medical care personnel should increase the inspection frequency of the concentration detector 21 so that the purifying apparatus 30 can be replaced in time before the purifying apparatus 30 is out of order. That is, the flow detector 22 can act as a safety feature.

The flow sensor 22 of the present utility model is connected to the buffer tube 10 and the purge device 30 by a threaded connection, a snap fit connection, an adhesive connection, or the like. The flow detector 22 in this embodiment is threaded with the buffer tube 10 and threaded with the purification device 30, which facilitates the replacement of the purification device 30 by a healthcare worker and enables the reuse of the entire detection assembly 20. The flow detector 22 is used to detect the amount of liquid flowing through the purification device 30. The flow rate detector 22 in this embodiment employs a turbine flow meter.

To further reduce the workload of the healthcare worker, in one embodiment of the present utility model, the detection assembly 20 further includes an alarm (not shown) for detecting readings from the concentration detector 21 and the flow detector 22 and alerting if the decontamination device fails or is about to fail.

Specifically, the alarm is built in the concentration detector 21, the concentration detector 21 and the flow detector 22 are electrically connected with the alarm, and when the alarm detects that the concentration value of the disinfection medium measured by the concentration detector 21 does not meet the standard requirement or is close to the minimum value required by the standard requirement, the alarm gives an alarm to remind medical staff to replace the purification device 30 in time; generally, when the amount of liquid filtered by the purification apparatus 30 reaches a certain level, manufacturers also recommend that the purification apparatus 30 be replaced by a person to prevent the purification apparatus 30 from being disabled; therefore, the alarm of the present utility model can also read the value of the flow detector 22, and when the amount of liquid flowing through the purifying device 30 reaches or approaches the limit value, the alarm will also give an alarm to prompt the medical staff to replace the purifying device 30.

In summary, in the present utility model, whether the cleaning device 30 is required to be replaced is determined by directly detecting the concentration of the disinfection medium in the liquid flowing through the cleaning device 30 or detecting the amount of the liquid flowing through the cleaning device 30, so that whether the cleaning device 30 is out of order can be accurately determined, the cost is saved compared with the periodic replacement of the cleaning device 30, the amount of the liquid filtered by the cleaning device 30 is more accurate compared with the estimation of the amount of the liquid filtered by the cleaning device 30, the liquid flowing out of the waterway can be ensured to meet the use requirement, and the damage of the liquid with the exceeding colony standard to the patient is prevented; the buffer tube 10 can not only enable the disinfection medium to be further mixed with the liquid, but also effectively reduce the flow rate of the liquid, so that the concentration detector 21 can conveniently and accurately measure the concentration of the disinfection medium in the liquid; the cross-sectional area of the cavity is larger than the cross-sectional areas of the opening 16 and the inlet 14, so that the liquid can be firstly decelerated and then accelerated when entering the cavity, the concentration of the disinfection medium can be conveniently measured, and the flow rate of the liquid flowing out of the detection device can be ensured to meet the use requirement.
