Drainage bag for storing and taking specimens

Abstract

Drainage liquid in a drainage tube firstly flows through a dropper arranged on the drainage tube, interception of the drainage liquid can be achieved through cooperation of the dropper and an adjustor fixed to the drainage tube, when the drainage liquid of a patient is little, the adjustor enables the drainage liquid in the drainage tube to stop flowing downwards, and therefore the drainage liquid in the drainage tube can be retained. At the moment, the drainage liquid is continuously accumulated in the drainage tube and the dropper above the regulator, and when the regulator blocks the circulation of the drainage tube, the drainage tube can be communicated with the atmosphere through the exhaust hole, so that the drainage liquid continuously flows downwards along the drainage tube until the drainage liquid intercepted in the dropper reaches a sample amount required by detection; and the sample is reserved through the sampling opening formed in the drainage tube and close to the bottom of the dropper, so that the situation that enough sample cannot be sucked for a long time when the drainage liquid of the patient is less is avoided, the operation of reserving the sample is simpler and more convenient, and the risks of patient infection and sample pollution are reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a drainage bag for collecting specimens. Background Art

[0002] Drainage bags are commonly used medical devices in clinical medical work to collect fluid flowing out of drainage tubes. Drainage bags can be used for drainage during injection treatments such as infusion and blood transfusion. For patients undergoing surgical, abdominal and urinary system surgeries, as well as long-term care patients, drainage bags can be used to collect excrement, gastric juice, postoperative wound fluid and bleeding, etc. In order to detect and analyze the patient's condition, it is necessary to collect samples of the body fluid in the drainage bag for testing.

[0003] Generally, there are two ways to connect a drainage tube to a drainage bag: one is to directly connect the drainage bag to the rubber drainage tube left in place during surgery; the other is to connect the drainage bag to a drainage tube with a spiral joint. For the first type of connection, medical staff need to disinfect the drainage tube before taking specimens, and then pierce the drainage tube with a syringe with a needle to draw out the drainage fluid; for the second type of connection, medical staff need to unscrew the spiral joint, hold the disinfected items and the drainage tube in one hand to disinfect the joint, hold the syringe and the drainage bag in the other hand, aim the syringe at the joint to draw out the drainage fluid, then wipe and disinfect the drainage tube joint again, and then screw the drainage bag to the drainage tube. The operation is extremely cumbersome and time-consuming, which is not conducive to clinical work, and there is a risk of incomplete disinfection of the joint and contamination of the specimen.

[0004] Moreover, when the patient has less drainage fluid, no matter whether the syringe is inserted into the drainage tube or the suction is performed at the interface of the drainage tube, there is a situation where no drainage fluid sample can be sucked out or the suctioned drainage fluid cannot reach the required volume for detection, resulting in a long period of time when the sample cannot be collected, causing delays in the timing of clinical detection and the patient's condition. Therefore, a drainage bag that is convenient for collecting samples and can guarantee the amount of samples collected is urgently needed. Utility Model Content

[0005] The utility model aims to provide a drainage bag for collecting specimens, so as to solve the problem that the existing drainage bags are inconvenient for collecting specimens and cannot ensure that the collected specimen volume reaches the capacity required for detection.

[0006] In order to solve the above technical problems, the utility model provides a drainage bag for collecting specimens, including a drainage tube, the drainage tube is connected to the drainage bag, a dropper is arranged on the drainage tube, the dropper is located above the drainage bag, the top side of the dropper is connected to an exhaust cap, the top of the exhaust cap is provided with an exhaust hole, the drainage tube is provided with a sampling port close to the bottom of the dropper, and a regulator fixed to the drainage tube is provided below the sampling port.

[0007] It should be noted in the scheme that the sampling port includes a handheld portion that wraps around the drainage tube, a puncture tube connected to the drainage tube is provided on one side of the handheld portion, and a rubber sleeve is installed on the puncture tube.

[0008] As a preferred embodiment, a protective pad is provided on the puncture tube, and the width of the protective pad exceeds the width of the handheld part by 1.5-2.5 cm.

[0009] As a preferred embodiment, both sides of the hand-held portion are provided with concave arc surfaces, and the arc surfaces of the hand-held portion are made of anti-slip material.

[0010] It is further worth mentioning that a breathable membrane is installed on the exhaust hole.

[0011] As a preferred implementation, both the dropper and the drainage bag are provided with scale lines.

[0012] It is further worth mentioning that a hanging ring is fixed on the top of the drainage bag.

[0013] Compared with the prior art, the drainage bag for collecting specimens provided by the utility model has at least the following beneficial effects:

[0014] The drainage tube is connected to the liquid outlet tube led out of the patient's body. The drainage tube is connected to a drainage bag. The patient's body fluid flows into the drainage bag through the drainage tube. The drainage fluid in the drainage tube will first flow through a dropper provided on the drainage tube. The drainage fluid can be retained by the dropper in conjunction with a regulator fixed on the drainage tube. When the patient's drainage fluid is less, the regulator is used to stop the drainage fluid in the drainage tube from flowing down. At this time, the drainage fluid continues to accumulate in the drainage tube and the dropper above the regulator. An exhaust cap is connected to the top side of the dropper. An exhaust hole is provided on the top. When the regulator blocks the flow of the drainage tube, the drainage tube can be connected to the atmosphere through the exhaust hole, so that the drainage fluid can continue to flow down the drainage tube until the drainage fluid retained in the dropper reaches the sample volume required for detection, and then the sample is collected through the sampling port provided on the drainage tube near the bottom of the dropper, thereby avoiding the situation that a sufficient amount of sample cannot be drawn for a long time when the patient has less drainage fluid. Compared with the sample collection operation drawn from the drainage tube interface, the sample collection operation is simpler and more convenient, and the risk of patient infection and sample contamination is reduced.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] The core of the utility model is to provide a drainage bag for collecting specimens, which solves the problem that the existing drainage bags are inconvenient for collecting specimens and cannot ensure that the collected specimen volume reaches the capacity required for detection.

[0022] Figure 1 A schematic diagram of the structure of a drainage bag for collecting specimens provided by the utility model. Figure 2 This is a schematic diagram of the enlarged structure of point A provided by the utility model. Figure 3 The schematic diagram of the sampling port structure provided by the utility model is shown in FIG. Figures 1 to 3 shown.

[0023] Example 1

[0024] A drainage bag for collecting specimens, comprising a drainage tube 1 for connecting to a liquid outlet tube drawn out of a patient's body, Figure 1The drainage tube 1 is connected to a drainage bag 2, through which the patient's body fluid can be drained into the drainage bag 2 for storage. It should be noted that the interface at the top of the drainage tube 1 is a spiral interface or a pagoda interface, which is used to adapt to and connect the existing two different joints of the liquid outlet tube. A dropper 3 is arranged on the drainage tube 1, and the dropper 3 is located above the drainage bag 2. The dropper 3 can be used to intercept and store a sufficient amount of drainage fluid specimen required for detection. A sampling port 6 close to the bottom of the dropper 3 is arranged on the drainage tube 1, and the sampling port 6 is connected to the drainage tube 1. After the sampling port 6 is disinfected, the drainage fluid in the drainage tube 1 can be sampled by inserting a syringe into the sampling port 6. Compared with the original unscrewing the spiral interface, disinfecting the interface, and then using the syringe to draw out the drainage fluid at the interface, after the specimen collection is completed, the interface must be disinfected again and the connection is re-screwed. The specimen collection is simpler and more convenient, which is beneficial to clinical work, and reduces the risk of incomplete disinfection at the interface and contamination of the specimen.

[0025] It is worth noting that, in addition to being able to retain the drainage fluid, the setting of the dropper 3 can also assist medical staff in controlling the time required to drain a specified amount of drainage fluid, so as to avoid medical staff forgetting to close the regulator 7 due to busy clinical work or rescuing patients, resulting in excessive drainage fluid being drained in a short period of time, causing excessive loss of body fluids in patients, causing discomfort reactions such as rapid heart rate and blood pressure. Medical staff can calculate the drainage speed by the number of drops of drainage fluid dripped by the dropper 3 within one minute, and estimate the drainage time based on the estimated drainage volume. On the one hand, if medical staff find that the current drainage speed is too fast or too slow, they can adjust the regulator 7 to make the drainage fluid flow down at an appropriate speed to ensure that the target drainage volume is reached within a unit time, so as to avoid the adverse effects of the patient's organs being compressed by the effusion for a long time due to the slow flow rate of the drainage fluid, or the discomfort reactions that may be caused to the patient due to the excessively fast flow rate. On the other hand, medical staff can close the regulator 7 in time according to the estimated drainage time to ensure the smooth completion of the drainage.

[0026] A regulator 7 fixed on the drainage tube 1 is provided below the sampling port 6. The flow rate of the drainage fluid in the drainage tube 1 can be adjusted and controlled by the regulator 7. When the patient has less drainage fluid, the regulator 7 is used to block the flow of the drainage fluid in the drainage tube 1. The top side of the dropper 3 is connected to an exhaust cap 4, and an exhaust hole 5 is provided on the top of the exhaust cap 4. Figure 1 and Figure 2 The drainage tube 1 can be connected to the atmosphere through the exhaust hole 5, so as to avoid excessive pressure in the drainage tube 1 affecting the flow of the drainage fluid, and ensure that the drainage fluid can continue to flow down the drainage tube to the blocking position of the regulator 7. The drainage fluid will continue to accumulate in the drainage tube 1 above the dropper 3 and the regulator 7 until the drainage fluid retained in the dropper 3 reaches the sample volume required for the test, and then the sample is collected through the sampling port 6, so as to avoid the situation that a sufficient amount of sample cannot be collected for a long time when the patient's drainage fluid is less, and ensure the timeliness of the sample collection and delivery for inspection, so as to provide timely reference for clinical work and avoid delaying the patient's condition.

[0027] In one possible implementation, see Figure 3 The sampling port 6 includes a handheld portion 600 that wraps around the drainage tube 1. Preferably, the handheld portion 600 is made of plastic. A puncture tube 610 connected to the drainage tube 1 is provided on one side of the handheld portion 600. A rubber sleeve 620 is installed on the puncture tube 610. The syringe is inserted into the rubber sleeve 620 and passed through the puncture tube 610, and then inserted into the drainage tube 1 to extract the drainage fluid specimen. The rubber sleeve 620 has good density and is not easy to leak. When the syringe is inserted into the rubber sleeve 620, a hole that can tightly wrap the syringe head is forced to appear. When the specimen is collected, the syringe is withdrawn and the rubber sleeve is removed. The hole of the rubber sleeve 620 is restored when the external force is removed, which can ensure the airtightness of the drainage system when no specimen is collected. The puncture tube 610 can assist in limiting the syringe head to ensure that the syringe head can stably extend into the drainage tube 1 to obtain liquid. It is worth mentioning that when collecting specimens, medical staff often use excessive force to cause the syringe to penetrate the drainage tube and stab the palm of the hand holding the drainage tube. The handheld part 600 can not only facilitate medical staff to feel the puncture force, but also protect against accidental needle stick injuries that may be caused when collecting specimens, and prevent safety hazards in the operation of collecting specimens.

[0028] Example 2

[0029] On the basis of Example 1, in order to further ensure the safety of medical staff in the process of collecting specimens, a protective pad 630 is provided on the puncture tube 610. Figure 1 and Figure 3 When holding the hand-held part 600 with one hand and holding the syringe for puncture with the other hand, the width of the protection pad 630 exceeds the width of the hand-held part 600 by 1.5-2.5 cm. The protection pad 630 can protect the operator's fingers from being stabbed due to the deviation of the syringe head caused by anxiety or accidents. 1.5-2.5 cm is the width range of a finger, which can ensure that when the operator holds the hand-held part 600, the fingers can be completely covered and protected by the protection pad 630. Preferably, the color of the protection pad 630 can be a color different from the yellow color of the rubber sleeve 620, such as blue. Through this design, the rubber sleeve 620 can be highlighted, that is, the point to be punctured can be highlighted, so that medical staff can quickly and accurately find the insertion point of the syringe in clinical work, thereby improving the safety of specimen collection operation and improving operation efficiency.

[0030] It is further worth noting that, see Figure 3Both sides of the handheld portion 600 are provided with concave arc surfaces for easy holding. Preferably, one side of the handheld portion 600 is provided with an arc surface matching the arc of three fingers, and the other side is provided with an arc surface matching the arc of the thumb, which is convenient for medical staff to hold and improves the holding stability. The arc surface of the handheld portion 600 is made of non-slip material. During manufacturing, the arc surface of the handheld portion 600 can be frosted to avoid slipping during puncture due to hand sweat or residual disinfectant or water on the hands.

[0031] In order to prevent the retained drainage liquid from exceeding the height of the exhaust hole 5 in the dropper 3, causing the drainage liquid to leak out of the exhaust hole 5 or affecting the exhaust, a breathable membrane 12 is installed on the exhaust hole 5, see Figure 2 The breathable membrane 12 can ensure that if the drainage liquid exceeds the height of the vent 5, the drainage liquid will not overflow from the vent 5, and can still ensure that the dropper 3 and the drainage tube 1 can be connected to the atmosphere, so that the drainage liquid can flow down smoothly.

[0032] As a preferred embodiment, see Figure 1 , scale lines 8 are provided on the dropper 3 and the drainage bag 2. The scale lines 8 on the dropper 3 can facilitate medical staff to observe whether the retained specimen in the dropper 3 reaches the capacity required for detection, and timely retain the specimen after the specimen volume is reached. The scale lines 8 on the drainage bag 2 can facilitate medical staff to observe and grasp the amount of drainage fluid flowing out of the patient, and timely use the regulator 7 to control the outflow of drainage fluid according to the amount of drainage fluid in the drainage bag 2. Furthermore, in order to facilitate adjusting the drainage bag 2 to a suitable position according to the patient's position, a hanging ring 9 is fixed on the top of the drainage bag 2, and the drainage bag 2 can be hung to a suitable place through the hanging ring 9 to avoid discomfort to the patient due to the pulling force of the drainage bag 2.

[0033] It should be noted that a pouring port 10 is provided at the bottom side of the drainage bag 2 , and a drain valve 11 is installed on the pouring port 10 . When the drainage liquid in the drainage bag 2 needs to be discharged, the drain valve 11 can be opened to discharge the drainage liquid through the pouring port 10 .

[0034] The utility model allows the patient's body fluid to flow into the drainage bag 2 through the drainage tube 1. The drainage fluid first flows through the drainage tube 1 provided with a dropper 3. When the patient's drainage fluid is less, the dropper 3 can be used to cooperate with the regulator 7 fixed on the drainage tube 1 to intercept the drainage fluid. The regulator 7 is first used to stop the drainage fluid in the drainage tube 1 from flowing down. At this time, the drainage fluid will continue to accumulate in the drainage tube 1 and the dropper 3 above the regulator 7. The top side of the dropper 3 is connected to an exhaust cap 4, and the top of the exhaust cap 4 is provided with an exhaust cap. Hole 5. When the regulator 7 blocks the flow of the drainage tube 1, the drainage tube 1 can be connected to the atmosphere through the exhaust hole 5, so that the drainage fluid can continue to flow down the drainage tube 1 until the drainage fluid retained in the dropper 3 reaches the sample volume required for detection, and then the sample is collected through the sampling port 6 arranged on the drainage tube 1 near the bottom of the dropper 3, thereby avoiding the situation that a sufficient amount of sample cannot be sucked for a long time when the patient's drainage fluid is less. Compared with the sample collection operation sucked from the interface of the drainage tube 1, the sample collection operation is simpler and more convenient, and the risk of patient infection and sample contamination is reduced.
