DETAILED DESCRIPTION

[0019] In order to make the technical scheme of the utility model better understood by the skilled in the art, the utility model will be further described in detail below in combination with the drawings.

[0020] As Figure 1 Indicated, a kind of collectable precision drainage bag, including three sequentially fixed communication of drainage bag body 1, medical three-way valve 2 and measuring tube 3, and medical three-way valve 2 is fixed communication in the liquid inlet of drainage bag body 1, the outer wall of measuring tube 3 is provided with scale line 31. By controlling medical three-way valve 2 to make the three ports of medical three-way valve 2 each not communicate, and then when the liquid of drainage enters measuring tube 3, liquid is accumulated in measuring tube 3 at this time, the volume of liquid of drainage is accurately measured by observing scale line 31 on measuring tube 3, when the liquid in measuring tube 3 is more, the volume of liquid in the measuring tube 3 is recorded and medical three-way valve 2 is opened to make the liquid in measuring tube 3 flow to drainage bag body 1 to be collected, and then medical three-way valve 2 is closed again, to use measuring tube 3 again to collect, the total drainage volume is obtained by the superposition of recorded data, compared with the rough measurement using the scale on drainage bag, the measurement of measuring tube 3 is more accurate.

[0021] As the further provided technical scheme of the utility model, the liquid outlet of drainage bag body 1 is provided with drain pipe 11, and the bottom end of drain pipe 11 is inserted and connected with switch valve 12.

[0022] Specifically, sliding member 13 is slidably arranged in switch valve 12, and sliding member 13 slides to close the liquid flow port 14 opened in switch valve 12. As Figure 2 Indicated, by pressing sliding member 13 to close liquid flow port 14, to avoid the liquid in drainage bag body 1 along liquid flow port 14, and then when the drainage liquid accumulated in drainage bag body 1 is more, liquid flow port 14 is opened by turning sliding member 13, at this time, the liquid in drainage bag body 1 is discharged from drainage bag body 1 along liquid flow port 14, so as to continue to use drainage bag body 1.

[0023] Further, one end of measuring tube 3 relative to medical three-way valve 2 is fixedly communicated with liquid inlet pipe 32, and pipe clamp 33 is movably arranged on liquid inlet pipe 32.

[0024] Specifically, as Figure 1As shown, the measuring tube 3 is communicated with an exhaust pipe 38, and a single-way valve 39 is fixedly installed in the exhaust pipe 38. By using the exhaust pipe 38 and the single-way valve 39, when the liquid in the liquid inlet pipe 32 enters the measuring tube 3, the gas squeezed by the liquid can pass through the single-way valve 39 opened along the exhaust pipe 38 to be discharged from the measuring tube 3, and the falling of the liquid is further accelerated. The pipe clamp 33 is provided with an elastic part 35, and the pipe clamp 33 is provided with a through slot 37 for penetrating the liquid inlet pipe 32. The outer wall of the liquid inlet pipe 32 on one side and the elastic part 35 are respectively rotationally provided with a roller 36. The elastic part 35 is in a default state of being away from the outer wall of the liquid inlet pipe 32. The pipe clamp 33 is fixedly installed with a elastic nylon rope 34, and one end of the elastic nylon rope 34 is fixedly installed on the outer wall of the liquid inlet pipe 32. The liquid inlet pipe 32 and the elastic part 35 are respectively elastic plastic plates.

[0025] When the medical three-way valve 2 is opened to make the liquid in the measuring tube 3 flow to the drainage bag body 1 for collection, the user fixes the liquid inlet pipe 32, and then holds the pipe clamp 33 and the elastic part 35 with hands to clamp the liquid inlet pipe 32 by the pipe clamp 33 and the elastic part 35. At this time, the rollers 36 on the pipe clamp 33 and the elastic part 35 respectively squeeze the liquid inlet pipe 32, and the rollers 36 are used to reduce the friction between the pipe clamp 33, the elastic part 35 and the outer wall of the liquid inlet pipe 32. Then, the liquid in the liquid inlet pipe 32 is squeezed into the measuring tube 3 by the rollers 36 on the pipe clamp 33, and then flows into the drainage bag body 1. At the same time, the elastic nylon rope 34 is deformed to store energy, and then the pipe clamp 33 is released to be reset to the original height under the elastic reset state of the elastic nylon rope 34. The liquid in the liquid inlet pipe 32 is squeezed into the measuring tube 3 by the squeezing and sliding of the pipe clamp 33.

[0026] If the similar single-opening measuring container and the liquid inlet pipe 32 are fixedly communicated, the single-opening measuring container needs to be taken off from the liquid inlet pipe 32 after the single-opening measuring container is full, and part of the drainage liquid will be taken out when taken out, and the taken-out drainage liquid is often relatively smelly, which has certain stimulation to the patients and medical staff, and is easy to cause discomfort and vomiting. The drainage bag body 1, the medical three-way valve 2, the measuring tube 3 and the liquid inlet pipe 32 are sequentially communicated, which can avoid the problem of liquid outflow when the liquid is discharged from the measuring tube 3.

[0027] Further, the medical three-way valve 2 is provided with a clear liquid pipe 21.

[0028] Specifically, the clear liquid pipe 21 is inserted with a plug 22. Since the drainage liquid is mostly thick and easy to adhere to the inner wall of the measuring tube 3, in order to clean the measuring tube 3, the medical three-way valve 2 is controlled to make the measuring tube 3 and the clear liquid pipe 21 communicate, and the measuring tube 3 and the drainage bag body 1 remain closed, then the plug 22 of the clear liquid pipe 21 is pulled out, and a cleaning liquid is injected into the measuring tube 3 through a syringe, so as to clean the adhered liquid, and then the cleaning liquid is discharged along the clear liquid pipe 21, thereby facilitating the subsequent use of the measuring tube 3.

[0029] Further, the measuring tube 3 is a hard transparent plastic tube.

[0030] Specifically, the measuring tube 3 is a hard transparent plastic tube, so that the measuring tube 3 is more accurate than the measuring of the drainage bag body 1, and the transparent design facilitates the observation of the volume of the liquid.

[0031] Further, the liquid inlet pipe 32 is a rubber hose.

[0032] Specifically, the rubber hose facilitates the extrusion of the liquid inlet pipe 32 by the tube clamp 33.

[0033] Further, the drainage bag body 1 is a transparent plastic bag.

[0034] Working principle: the medical three-way valve 2 is controlled to make the three ports of the medical three-way valve 2 not communicate with each other, then when the drainage liquid enters the measuring tube 3, the liquid is accumulated in the measuring tube 3, the scale line 31 on the measuring tube 3 is observed to accurately measure the volume of the drainage liquid, when the liquid in the measuring tube 3 is more, the volume of the liquid in the measuring tube 3 is recorded, then the medical three-way valve 2 is opened to make the liquid in the measuring tube 3 flow into the drainage bag body 1 to be collected, and the total drainage volume is obtained by recording the superposition of the data, compared with the rough measurement by the scale on the drainage bag, the measurement of the measuring tube 3 is more accurate.

[0035] The above only describes some exemplary embodiments of the present application by way of illustration, without doubt, for ordinary skilled in the art, without departing from the spirit and scope of the present application, the described embodiments can be modified in various ways. Therefore, the above drawings and description are illustrative in nature, and should not be understood as limiting the scope of protection of the present application.
