Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drainage bag which is convenient for sampling drainage fluid, reducing sample contamination and component testing. Background Art

[0002] Drainage bags are commonly used medical equipment, mainly used to collect drainage fluid from the abdominal cavity, chest cavity, etc. The properties and composition of the drainage fluid are important clinical observation indicators. Currently, disposable drainage bags (anti-reflux type) made of plastic are widely used in clinical practice and are replaced every 3 days or so. The commonly used clinical specimen collection method is to use a syringe with a needle to directly extract the drainage fluid from the leaking part of the drainage tube in the body, or to directly disconnect the drainage tube from the drainage bag at the joint of the drainage tube in the body, and use a wide-mouth specimen bottle to collect the drainage fluid. Both collection methods are easy to contaminate the specimen and increase the risk of occupational exposure. Utility Model Content

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a drainage bag that is convenient for sampling drainage fluid and reduces sample contamination, so as to reduce the risk of occupational exposure.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A drainage bag comprises a liquid storage bag and a drainage tube connected to the top of the liquid storage bag. A liquid collection chamber is provided on the drainage tube. The liquid collection chamber is a hollow cylindrical structure and is integrally formed with the drainage tube. A liquid collection hole is opened on one end surface of the liquid collection chamber and a liquid collection hole cover matched with the liquid collection hole is detachable to close the liquid collection hole.

[0006] Furthermore, an anti-dropping strip is rotatably provided on the liquid collection hole cover, a through hole is opened on the surface of the anti-dropping strip at one end away from the liquid collection hole cover and is sleeved on the drainage tube to prevent the liquid collection hole cover from falling off.

[0007] Furthermore, a detection chamber is provided on the drainage tube. The detection chamber is a rectangular cavity structure and is integrally formed with the drainage tube. A detection test paper is provided in the cavity of the detection chamber.

[0008] Furthermore, the detection chamber is located between the drainage tube outlet and the liquid collection chamber.

[0009] Furthermore, the test paper is one of a pH test paper, a starch phenol test paper or a bile test paper.

[0010] Furthermore, a liquid-stopping clip is sleeved on the drainage tube to facilitate clamping and closing the drainage tube.

[0011] Furthermore, scale lines and numerical values ​​are arranged on the surface of the liquid storage bag along its length direction to facilitate observation of the capacity.

[0012] Furthermore, a drainage pipe connected to the liquid storage bag is provided at the bottom thereof, and an external thread is provided on the outer peripheral surface of the drainage pipe near the outlet end of the drainage pipe and is threadedly connected with a drainage pipe cover.

[0013] Furthermore, a hanging ear is provided on the top of the liquid storage bag.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model sets a liquid collection chamber on the drainage tube. When it is necessary to sample the drainage fluid, first open the liquid collection hole cover of the liquid collection chamber, and then bend the drainage tube to temporarily block the drainage fluid in the drainage tube from flowing into the liquid storage bag, so that the drainage fluid in the liquid collection chamber gradually increases, and finally insert the syringe into the liquid collection chamber from the liquid collection hole to take the sample. In this way, it avoids using a syringe with a needle to directly extract the drainage fluid from the leaking part of the drainage tube in the body, or using a wide-mouth specimen bottle to collect the drainage fluid, which causes sample contamination and reduces the risk of occupational exposure. It is not only simple and convenient to operate, but also has a low production cost, and is suitable for popularization and application.

[0016] 2. A detection chamber is set on the drainage tube, and a detection test paper is arranged in the cavity of the detection chamber. On the one hand, when the drainage fluid in the drainage tube flows through the detection chamber, the detection test paper in the cavity of the detection chamber develops color. The pH value of the drainage fluid is observed by comparing the detection test paper color card, so as to judge the nature of the drainage fluid, so that medical staff can observe whether the patient's condition changes at any time.

[0017] 3. A stopper card is set on the drainage tube, which can easily adjust the clamping of the drainage tube, simplifying the operation process while further ensuring the clamping effect to meet the patient's treatment needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred parts must have a specific position, and a specific position structure and operation. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be specifically understood, and therefore cannot be understood as limiting the present invention. The present invention is further described in detail below in conjunction with the drawings.

[0024] like Figure 1 and Figure 2 As shown, a drainage bag is provided in this embodiment, including a rectangular liquid storage bag 1 and a drainage tube 2 connected to the top of the liquid storage bag, so that the drainage fluid flows into the liquid storage bag through the drainage tube. The capacity of the liquid storage bag in this embodiment is 1000ml, and liquid storage bags of other specifications can also be used as needed. A liquid collection chamber 3 (made of transparent material) is provided on the drainage tube 2. The liquid collection chamber is a hollow cylindrical structure and is integrally formed with the drainage tube. The diameter of the liquid collection chamber is 1-2cm, and the height of the liquid collection chamber is 2-4cm; a liquid collection hole is opened on one end face of the liquid collection chamber, and a liquid collection hole cover 4 matched therewith is disassembled to close the liquid collection hole to avoid leakage of the drainage fluid. The liquid collection hole cover is made of plastic material and has a "T" structure in cross section. The size of the liquid collection hole is compatible with the syringe nipple, which is convenient for sampling with the help of a sterile device (such as a syringe).

[0025] When it is necessary to sample the drainage fluid, first open the liquid collection hole cover of the liquid collection chamber, bend the drainage tube to temporarily block the drainage fluid in the drainage tube from flowing into the liquid storage bag, so that the drainage fluid in the liquid collection chamber gradually increases, and finally insert the syringe into the liquid collection chamber from the liquid collection hole to take the sample. In this way, it avoids using a syringe with a needle to directly extract the drainage fluid from the leaking part of the drainage tube in the body, or using a wide-mouth specimen bottle to collect the drainage fluid, which causes sample contamination and reduces the risk of occupational exposure. Not only is the operation simple and convenient, but the production cost is low, and it is suitable for promotion and application.

[0026] Furthermore, to prevent the liquid collection hole cover from falling or being lost, in this embodiment, an anti-dropping strip 41 is rotatably provided on the liquid collection hole cover, and a through hole is opened on the surface of the anti-dropping strip at one end away from the liquid collection hole cover and is sleeved on the drainage tube 2 to prevent the liquid collection hole cover from falling.

[0027] During actual use, an annular cover can be further provided on the drainage tube. The inner diameter of the annular cover matches the diameter of the liquid collection chamber, and the annular cover is detachably connected to the liquid collection chamber by means of threads or snap connections, so as to further prevent the liquid collection hole cover from accidentally opening or falling off and causing leakage of the drainage fluid.

[0028] In order to facilitate clinical medical staff to observe the pH value of drainage fluid (such as cerebrospinal fluid, duodenal fluid, urine, etc.), judge the properties of drainage fluid, and observe changes in the patient's condition. In this embodiment, a detection chamber 5 (made of transparent material) is provided on the drainage tube 2. The detection chamber is a rectangular cavity structure. The detection chamber surface and the outer peripheral surface of the drainage tube are respectively provided with liquid measuring holes corresponding to each other, so that the drainage fluid in the drainage tube can flow into the detection chamber cavity. The detection chamber and the drainage tube are integrally formed, and a detection test paper is provided in the detection chamber cavity for testing the composition of the drainage fluid.

[0029] In this way, when the drainage fluid in the drainage tube flows through the detection chamber, the test paper in the detection chamber cavity develops color, and the pH of the drainage fluid can be observed by comparing the test paper color card, thereby judging the nature of the drainage fluid, so that medical staff can observe whether the patient's condition changes at any time. On the other hand, it avoids the pH of the drainage fluid at the current moment from mixing with the drainage fluid in the liquid storage bag, which affects the judgment of the nature of the drainage fluid, and can improve the accuracy of the detection.

[0030] Furthermore, in order to prevent the test paper from contaminating the sample and affecting the test result of the sample, in this embodiment, the detection chamber on the drainage tube is arranged between the drainage tube outlet and the liquid collection chamber.

[0031] The above-mentioned test paper is one of pH test paper, starch phenol test paper or bile test paper, etc., or a combination of two.

[0032] It should be further explained that the detection chamber and the drainage tube may not be made into an integrated structure. Specifically, a reflux tube is used, one end of the reflux tube is connected to the drainage tube, and the other end of the reflux tube is detachably connected to the detection chamber through a plug connector, so that the detection chamber can be replaced.

[0033] Furthermore, some patients need to temporarily clamp the drainage tube after the tube is placed due to treatment needs, and the current clamping method generally involves folding the middle section of the drainage tube and then sticking it with tape or clamping it with a small clip, which is cumbersome and does not guarantee the clamping effect. Therefore, in this embodiment, a liquid stopper 6 (existing technology, the specific structure is not briefly described) is sleeved on the drainage tube to facilitate clamping the drainage tube.

[0034] In this way, by setting the liquid stop card, the clamping (opening or closing) of the drainage tube can be easily adjusted, which simplifies the operation process while further ensuring the clamping effect to meet the treatment needs of patients.

[0035] In order to facilitate observation of the capacity of the liquid storage bag, in this embodiment, scale lines and values ​​are provided on the surface of the liquid storage bag along its length direction.

[0036] In order to facilitate the discharge of drainage fluid in the liquid storage bag according to the needs of the patient and reduce the weight, in this embodiment, a drainage pipe 7 connected to the liquid storage bag 1 is provided at the bottom, and an external thread is provided on the outer peripheral surface of the drainage pipe near the outlet end of the drainage pipe and a drainage pipe cap 8 is threadedly connected. When the drainage fluid in the liquid storage bag needs to be discharged, the drainage pipe cap on the drainage pipe can be unscrewed, which is simple and convenient to operate.

[0037] For the convenience of use by patients, a hanging ear 9 is provided on the top of the liquid storage bag in this embodiment.

[0038] It should be further explained that the drainage bag is made of soft polyethylene plastic or polyethylene material for medical blood (fluid) transfusion equipment that meets national standards.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described by referring to the preferred embodiments of the utility model, those skilled in the art should understand that various changes can be made in form and details without departing from the spirit and scope of the utility model as defined in the appended claims.
