Description

Drainage device

Technical Field

The application relates to the technical field of medical instruments, in particular to a drainage device.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

In clinic, some patients require drainage tubes such as urological, thoracic, abdominal drainage tubes, etc. to be left in order to drain the fluid product from the patient. On the basis, the effusion led out by the drainage tube is collected, so that the effusion can be further processed and the effusion can be obtained later, and the analysis of the illness state of a patient can be assisted by whether the effusion is normal or not.

In the related art, a drainage bag is generally used as a collection container for collecting effusion, and at this time, the drainage bag and the drainage tube together form a drainage device.

However, there are many reports that there is often a deviation between the liquid accumulation amount obtained by the metering marks on the drainage bag and the actual liquid accumulation amount in the drainage bag, because the drainage bag is usually a plastic bag made of a transparent flexible material such as a medical polymer material and the shape of the drainage bag is irregular, and the shape of the drainage bag is changed with the amount of liquid accumulation. Specifically, when the accumulated liquid is more, the drainage bag is full and nearly round, and at the moment, the accumulated liquid displayed by the metering scale marks of the drainage bag is smaller than the actual accumulated liquid; correspondingly, when the effusion is less, the drainage bag is flat, and the effusion displayed by the metering scale marks of the drainage bag is larger than the actual effusion. Meanwhile, when the effusion enters the drainage bag, the drainage bag may form folds, errors exist in the effusion quantity displayed by the metering scale marks of the drainage bag, and information such as the property and the color of the effusion is not easy to learn.

For this purpose, a known way to know the liquid accumulation in the drainage bag relatively accurately is to pour the liquid accumulation in the drainage bag into an additional measuring cylinder by a medical staff, measure the liquid accumulation in the measuring cylinder, and pour the liquid accumulation in the measuring cylinder after the measurement to brush and sterilize the measuring cylinder. In this way, not only is the burden of the operation of the medical staff increased, but also the medical staff may feel nausea when repeatedly pouring out the effusion due to the complex effusion components, thereby causing discomfort to the medical staff.

Referring to fig. 1 to 3, an embodiment of the present application discloses a drainage device, in which fig. 1 shows a schematic structural diagram of an exemplary drainage device disclosed in the embodiment of the present application, fig. 2 is an enlarged partial structural diagram of the drainage device shown in fig. 1, and fig. 3 is a partial structural sectional view of the drainage device shown in fig. 1. In general, the drainage device disclosed in embodiments of the present application may include a drainage tube 10 and a collection cartridge 20.

In an embodiment of the application, the drainage tube 10 is used to effect the drainage of fluid product from within the patient to the outside of the body for collection by the collection cartridge 20. The drainage tube 10 is a drainage tube 10 used in a drainage device known in the prior art, and will not be described in detail herein.

Further, in some embodiments of the present application, as shown in fig. 1, the drainage device may further include a flow regulating valve 30 and a switch 40 disposed on the drainage tube 10, where the flow regulating valve 30 is configured to control the flow of the fluid flowing through the drainage tube 10, that is, the flow of the effusion flowing through the drainage tube 10 can be regulated by the flow regulating valve 30, and the switch 40 is configured to control the on/off of the drainage tube 10. Wherein the switch 40 may be, but is not limited to, a pinch-off clamp (also known as a Robert clamp) or other similar component.

In the embodiment of the present application, the collecting tube 20 is used for collecting the effusion guided to the outside of the patient through the drainage tube 10, so as to facilitate the subsequent further treatment of the effusion, and also facilitate the relevant medical staff to know the effusion, and the information of the nature, color, etc. of the effusion. Specifically, in connection with what is shown in fig. 1-3, the collection canister 20 may be a cylinder of transparent material (e.g., medical polyethylene or medical polypropylene, etc.), and the interior of the collection canister 20 also defines a first collection chamber 21 and a second collection chamber 22. Wherein the second collecting chamber 22 is located below the first collecting chamber 21, and the first collecting chamber 21 and the second collecting chamber 22 are mutually communicated, and the drainage tube 10 is communicated with the first collecting chamber 21, so that the accumulated liquid flowing through the drainage tube 10 can enter the first collecting chamber 21 and reach the second collecting chamber 22.

Meanwhile, in order to facilitate subsequent treatment of the accumulated liquid entering the inside of the collecting cylinder 20, the first collecting chamber 21 is provided with a liquid discharge port, and a liquid discharge valve 23 is provided at the liquid discharge port. Preferably, the liquid drain port may be disposed at the bottom of the first collecting chamber 21 or at a position close to the bottom of the first collecting chamber 21, so as to facilitate the subsequent and smooth opening of the liquid drain valve 23 to drain the accumulated liquid.

In general, the effusion introduced from the patient generally includes foreign substances such as mucosal tissue and sediment in addition to the liquid such as water and blood, and when the effusion enters the first collection chamber 21 of the collection tube 20 from the drainage tube 10, the effusion fills the second collection chamber 22 and the first collection chamber 21 in this order, and at this time, the foreign substances such as mucosal tissue and sediment in the effusion are deposited at the bottom of the second collection chamber 22. On the basis, by arranging the liquid discharge port on the first collecting chamber 21, when the liquid discharge valve 23 is opened to discharge the effusion, the liquid discharge port can be effectively prevented from being blocked by foreign matters such as mucosal tissues and sediment substances in the effusion, so that the effusion can be discharged more smoothly. It will be appreciated that in actual drainage of the fluid product, the entire cartridge 20 may be tilted at an angle to facilitate smooth drainage of the fluid product that is present in the second collection chamber 22 and that does not contain foreign matter such as mucosal tissue, sediment material, etc. Wherein, the inclination angle of the collecting cylinder 20 should satisfy: on the basis of smoothly discharging the accumulated liquid from the liquid discharge port, foreign matters such as mucosal tissues and sediment substances deposited at the bottom of the second collecting cavity 22 are prevented from reaching the liquid discharge port as much as possible.

On this basis, in order to facilitate the knowing of the amount of the liquid accumulation collected in the collection tube 20, referring to fig. 1 and 2, the outer wall of the collection tube 20 corresponding to the first collection chamber 21 is provided with a first metering scale 24, and the first metering scale 24 extends along the height direction of the first collection chamber 21; the outer wall of the collecting cylinder 20 corresponding to the second collecting cavity 22 is provided with a second metering graduation mark 25, and the second metering graduation mark 25 extends along the height direction of the second collecting cavity 22. Thus, the liquid accumulation amount in the first collecting cavity 21 can be obtained through the first metering graduation mark 24, the liquid accumulation amount in the second collecting cavity 22 can be obtained through the second metering graduation mark 25, and then the total liquid accumulation amount collected by the collecting cylinder 20 can be obtained through calculation of the liquid accumulation amounts in the first collecting cavity 21 and the second collecting cavity 22.

Therefore, the drainage device disclosed by the embodiment of the application collects the effusion by adding the collecting cylinder 20 with the first collecting cavity 21 and the second collecting cavity 22, and the first metering scale mark 24 and the second metering scale mark 25 which respectively correspond to the first collecting cavity 21 and the second collecting cavity 22 are arranged on the outer wall of the collecting cylinder 20, so that medical staff can know the amount of the effusion collected by the collecting cylinder 20 as accurately as possible, and the drainage device is beneficial to reducing the operation burden of the medical staff and relieving the discomfort caused to the medical staff.

Meanwhile, through the arrangement of the second collecting cavity 22, foreign matters such as mucosal tissues and sediment substances in the effusion are deposited at the bottom of the second collecting cavity 22, and the liquid outlet for discharging the effusion collected by the collecting cylinder 20 is arranged on the first collecting cavity 21 above, so that the liquid outlet can be effectively prevented from being blocked by the foreign matters such as mucosal tissues and sediment substances in the effusion when the effusion is required to be discharged subsequently, and the effusion discharging process is smoother.

In practical clinical practice, there may be a case where a small amount of effusion is obtained to be sent to a laboratory as a sample for testing, and the drain port of the known drain bag is usually disposed at the bottommost end of the drain bag, so that when the drain port is opened, a large amount of effusion is ejected, and therefore the outflow amount of effusion cannot be controlled well, and the outflow of a large amount of effusion may pollute the environment. Therefore, in the drainage device disclosed by the embodiment of the application, the liquid outlet is arranged on the first collecting cavity 21, when the accumulated liquid is only stored in the second collecting cavity 22, the liquid outlet can be opened to pour out a small amount of accumulated liquid, so that a small amount of accumulated liquid is obtained.

In some embodiments of the present application, and in conjunction with what is shown in fig. 1-3, the cartridge 20 further may include a first cartridge 26 and a second cartridge 27 positioned below the first cartridge 26. Wherein the first collection cartridge 26 is internally provided with a first collection chamber 21 and the second collection cartridge 27 is internally provided with a second collection chamber 22.

It is contemplated that in practice there may be situations where it is desirable to suspend the drainage device from the patient in order for the patient to perform some of the necessary daily activities. To this end, as shown in fig. 1 or 2, the first collection canister 26 may be an oval-shaped canister, which is advantageous in improving the stability of the entire drainage device when the drainage device is suspended from a patient by providing the first collection canister 26 as a flat oval-shaped canister. The second cartridge 27 may be a circular cylinder to facilitate placement of the cartridge 20 on a horizontal plane for reading when the healthcare worker needs to know the amount of fluid deposited in the cartridge 20.

Further, in some embodiments of the present application, the shape of the first collection chamber 21 may match the shape of the first collection tube 26, the shape of the second collection chamber 22 may match the shape of the second collection tube 27, that is, the first collection chamber 21 may be an oval chamber, the second collection chamber 22 may be a circular chamber, and the outer diameter of the second collection tube 27 is no greater than the length of the minor axis of the first collection tube 26. In this way, the flat first collection tube 26 is brought into contact with the patient when the drainage device is suspended from the patient, so that the amount of liquid that can be collected by the collection tube 20, that is, the maximum capacity of the collection tube 20, is increased as much as possible on the basis of increasing the stability of the whole drainage device.

For example, in actual practice, the maximum volumes of the first and second collection chambers 21 and 22 may be 800ml and 100ml, respectively, with a minimum graduation value of the first graduation mark 24 of 25ml and a minimum graduation value of the second graduation mark 25 of 10ml.

In some embodiments of the present application, as shown in fig. 2 and 3, the first collecting chamber 21 is further provided with a liquid inlet, and a one-way valve 28 is disposed at the liquid inlet, at this time, the drainage tube 10 is communicated with the first collecting chamber 21 through the one-way valve 28. By such arrangement, on the basis of realizing the communication between the drainage tube 10 and the first collecting chamber 21, the liquid accumulation can be effectively prevented from flowing back into the drainage tube 10 when the liquid accumulation is filled in the first collecting chamber 21 and the second collecting chamber 22 or the collecting cylinder 20 is poured.

Still further, in some embodiments of the present application, as shown in fig. 3, the liquid inlet may be disposed at the top of the first collecting chamber 21, and the liquid inlet is opposite to the communicating position between the first collecting chamber 21 and the second collecting chamber 22. Therefore, when the effusion enters the first collecting cavity 21 through the liquid inlet for the first time, the effusion directly falls into the second collecting cavity 22, so that the foreign matters such as mucous tissues, sediment substances and the like in the effusion are better deposited in the second collecting cavity 22.

In some embodiments of the present application, to facilitate hanging the drainage device on the patient or in other possible locations (e.g. on the patient's bed), the top of the collection cartridge 20 is also provided with a hanger 50, as shown in fig. 1 and 2. Of course, in other embodiments of the application, the lugs 50 may be provided at other suitable locations on the cartridge 20.

Further, in view of the actual application, there may be situations where the hospital bed is not suitable for hanging the drainage device, for example when there are no corresponding hooks or the like on the hospital bed. To this end, in some embodiments of the application, the drainage device may further comprise a snap ring 60.

Specifically, referring to fig. 1, 2 and 4, the clamping ring 60 is an annular non-closed belt-shaped member, a first end of the clamping ring 60 is provided with a clamping portion 61, and a second end of the clamping ring 60 passes through the hanging tab 50 and is provided with a clamping groove 62 adapted to the clamping portion 61. Thus, when the drainage device is required to be fixed on a sickbed and parts such as a hook for hanging the hanging lugs 50 are not arranged on the sickbed, the clamping ring 60 can be firstly sleeved on the hanging lugs 50, and then the clamping ring 60 is fixed on parts such as a railing of the sickbed, so that temporary fixation of the drainage device is realized, and the fixing process of the clamping ring 60 is facilitated to be simplified through the design of the clamping part 61 and the clamping groove 62.

Of course, in practical implementation, the connection between the first end and the second end of the clamping ring 60 is not limited to the manner of providing the clamping portion 61 and the clamping groove 62, but may be other conventional manners in the prior art capable of achieving detachable connection, for example, a manner of providing velcro on the first end and the second end of the clamping ring 60 may be adopted to achieve detachable connection between the first end and the second end of the clamping ring 61.

In addition, in combination with the foregoing, in practical application, there may be a case where the drainage device is suspended on the patient in order to perform necessary daily activities, however, when the patient carries the currently known drainage device to perform daily activities, since the drainage bag is completely transparent, it is easy for others to throw an abnormal gaze, thereby causing a psychological adverse effect on the patient.

To this end, in some embodiments of the application, a removable cover (not shown) may be further provided on the outer side wall on the front side of the cartridge 20, for example, a removable cover may be provided on both the outer side wall on the front side of the first cartridge 26 and the outer side wall on the front side of the second cartridge 27. Correspondingly, the first metering graduation mark 24 and the second metering graduation mark 25 are disposed on the outer sidewall of the rear side of the collecting barrel 20, so that the medical staff can know the accumulated liquid in the collecting barrel 20 when needed.

The front side of the collecting tube 20 refers to the side of the collecting tube 20 facing away from the patient (which can be understood as the side that can be seen by others) when the drainage device is hung on the patient, and the rear side of the collecting tube 20 refers to the side of the collecting tube 20 facing the patient (which can be understood as the side that cannot be seen by others) when the drainage device is hung on the patient. Meanwhile, the cover layer may be a colored decal or the like adhered to the corresponding outer side wall of the cartridge 20.

Thus, when the drainage device is hung on a patient, and the patient performs necessary daily activities, the patient can paste the covering layer on the outer side wall of the front side of the collecting cylinder 20 according to the needs, so that other people can only see the covering layer arranged on the collecting cylinder 20, and the abnormal eyes of other people when the other people throw the patient can be avoided as much as possible.

On the other hand, in connection with the above, since foreign matters such as mucosal tissue and sediment substances in the effusion entered into the collecting cylinder 20 are deposited at the bottom of the second collecting chamber 22, in order to facilitate the subsequent treatment of the foreign matters such as mucosal tissue and sediment substances deposited at the bottom of the second collecting chamber 22, in other embodiments of the present application, the second collecting cylinder 27 may be provided in a detachable structure.

Specifically, the second collection tube 27 may be detachably disposed at the bottom of the first collection tube 26 by screwing, and when it is necessary to treat foreign substances such as mucosal tissue and sediment deposited at the bottom of the second collection tube 27, it is only necessary to detach the second collection tube 27 from the first collection tube 26. Meanwhile, for the first and second collecting barrels 26 and 27 connected in a threaded connection manner, sealing elements such as sealing rings and gaskets should be arranged at the connection positions of the first and second collecting barrels 26 and 27, so that the sealing performance of the connection positions of the first and second collecting barrels 26 and 27 is improved, and leakage of accumulated liquid from the connection positions of the first and second collecting barrels 26 and 27 is prevented.

The above is only a preferred embodiment of the present application, and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
