Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to an anti-reflux liquid collection device around a wound drainage tube. Background Art

[0002] A drainage tube is a medical device used for clinical surgical drainage. It guides pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. It is generally made of materials such as silicone rubber or polyurethane. When in use, one end of the catheter is inserted into the drainage site in the body or on the wound, and the other end can be connected to other external devices such as the drainage tube outside the body to drain the fluid to the outside of the body through the action of pressure such as internal body pressure, gravity, or negative pressure suction.

[0003] When traditional drainage tubes are used in practice, patients often experience exudation around the drainage tubes after drainage of pleural effusion and ascites. The exudate in the abdominal cavity is mostly alkaline mucus, which can cause redness, swelling, rash and other adverse irritations to the skin. In particular, pancreatic juice, bile and intestinal juice can cause skin erosion and ulcers. Continuous exudate not only contaminates the patient's dressings, wets the patient's clothes and bed sheets, increases the workload of medical staff, but also increases the patient's psychological pressure. Utility Model Content

[0004] In order to collect exudate around wound drainage tubes and reduce the discomfort of patients and the workload of medical staff, the present application provides an anti-reflux liquid collection device around wound drainage tubes.

[0005] The above invention objectives of the present application are achieved through the following technical solutions:

[0006] A device for collecting liquid around a wound drainage tube with an anti-reflux function comprises a liquid collecting bag, wherein a central circular hole is provided on the top of the liquid collecting bag for allowing a drainage tube to pass through, a fixing component is provided on the periphery of the central circular hole for being adhered and fixed to the skin around the wound; an interface is provided on the bottom of the liquid collecting bag, the interface is provided with a valve, and an anti-reflux component is fixedly provided inside the liquid collecting bag.

[0007] By adopting the above technical scheme, the fixing component sticks the liquid collecting bag to the skin around the patient's wound, and the drainage tube passes through the central circular hole and extends into the liquid collecting bag. The central circular hole can be cut according to the size of the wound and the position of the drainage tube, thereby improving the practicality of the liquid collecting bag. The exudate around the drainage tube flows into the liquid collecting bag along the wall of the drainage tube and flows into the bottom of the liquid collecting bag through the anti-reflux component. The anti-reflux component can prevent the exudate from flowing back to the wound. An interface and a valve are provided at the bottom of the liquid collecting bag. The valve controls the switch of the liquid collecting bag outlet. The interface can be connected to an existing disposable drainage bag. When the liquid collecting bag is full, the exudate is discharged into the drainage bag, thereby avoiding damage or irritation to the wound caused by frequent replacement of the liquid collecting bag, which has the effect of reducing the patient's discomfort and the workload of medical staff.

[0008] Optionally, the fixing component is an adhesive chassis, and a side of the adhesive chassis in contact with the skin is provided with a ring-shaped chlorhexidine gluconate antibacterial gel, and an adhesive glue is provided on the periphery of the antibacterial gel.

[0009] By adopting the above technical solution, the annular chlorhexidine gluconate antibacterial gel can absorb part of the exudate, protect the skin, prevent the wound exudate from irritating the surrounding skin, and has an antibacterial effect. The adhesive can adhere the liquid collection bag to the skin, so that the liquid collection bag has a better fixing effect.

[0010] Optionally, the anti-reflux component is a bag-shaped valve group, which divides the liquid collecting bag into two parts, an upper part and an lower part. The bag-shaped valve group consists of a first valve and a second valve, and the first valve and the second valve are symmetrically arranged with respect to the longitudinal axis of the liquid collecting bag, and the opening ends of the first valve and the second valve are both facing the interface end.

[0011] By adopting the above technical scheme, the opening ends of the first valve and the second valve are both facing the interface end, and the first valve and the second valve divide the liquid collecting bag into two parts, upper and lower parts. When the exudate enters the upper part of the liquid collecting bag along the drainage tube wall, under the action of the pressure of the exudate, the first bag-shaped valve and the second bag-shaped valve are both attached to the inner wall of the liquid collecting bag, so that the exudate can flow smoothly to the lower part of the liquid collecting bag. When the exudate refluxes, the exudate will flow into the valve through the opening end of the first bag-shaped valve and the opening end of the second bag-shaped valve, the first bag-shaped valve and the second bag-shaped valve will be filled and expanded, and the outer surfaces of the first bag-shaped valve and the second bag-shaped valve will fit together, playing a cutting effect, and the refluxed exudate will be cut off at the lower part of the liquid collecting bag, so as to achieve the purpose of preventing the exudate from continuing to flow back toward the center circular hole end and causing irritation to the wound.

[0012] Optionally, a drainage tube tunnel is provided inside the liquid collecting bag, and the drainage tube tunnel is provided at the upper part of the liquid collecting bag. An inlet and an outlet are respectively provided at both ends of the drainage tube tunnel, and the outlet is fixedly connected to the side wall of the liquid collecting bag, and the inlet is provided inside the liquid collecting bag.

[0013] By adopting the above technical solution, the inlet of the drainage tube tunnel is arranged inside the liquid collecting bag, and the outlet is arranged on the side wall of the liquid collecting bag. The drainage tube extends into the liquid collecting bag through the central circular hole, and then passes through the drainage tube tunnel, extends out of the liquid collecting bag from the outlet of the drainage tube tunnel, and is externally connected to a disposable drainage bag. The drainage fluid inside the drainage tube enters the disposable drainage bag, and the exudate around the drainage tube enters the liquid collecting bag.

[0014] Optionally, the drainage tube tunnel is made of soft rubber material, the inlet and the outlet are originally closed, and both the inlet and the outlet are provided with tearable pressure marks.

[0015] By adopting the above technical scheme, the drainage tube tunnel is made of soft rubber material, which can produce a certain adsorption force on the drainage tube, thereby maintaining the airtightness of the liquid collecting bag when the drainage tube passes through, preventing external bacteria from entering the liquid collecting bag and causing wound infection, and the original state of the inlet and outlet is closed. When the liquid collecting bag is used on a wound without a drainage tube, it does not affect the airtightness of the liquid collecting bag. When the liquid collecting bag is used on a wound with a drainage tube, the inlet and outlet can be torn open along the tearable pressure mark to allow the drainage tube to pass through it; in addition, when some surgical wounds require negative pressure protection to promote healing, the negative pressure suction tube can be inserted into the liquid collecting bag from the outlet and the inlet in turn, and the external negative pressure is attracted to form a negative pressure environment in the liquid collecting bag.

[0016] Optionally, the liquid collecting bag is made of a transparent material, and scale lines are provided on the surface of the liquid collecting bag.

[0017] By adopting the above technical solution, the scale line makes it easy for medical staff to directly observe the storage volume of the exudate inside the liquid collection bag and open the valve in time to discharge the exudate.

[0018] Optionally, a colorimetric card is provided on the surface of the liquid collecting bag.

[0019] By adopting the above technical solution, the colorimetric card is convenient for medical personnel to refer to and uniformly describe the color of the exudate.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The fixing component sticks the liquid collection bag to the skin around the patient's wound, and the drainage tube passes through the central circular hole and extends into the liquid collection bag. The central circular hole can be cut according to the size of the wound and the position of the drainage tube, which improves the practicality of the liquid collection bag. The exudate around the drainage tube flows into the liquid collection bag along the wall of the drainage tube and flows into the bottom of the liquid collection bag through the anti-reflux component. The anti-reflux component can prevent the exudate from flowing back to the wound. The bottom of the liquid collection bag is provided with an interface and a valve, and the valve controls the switch of the outlet of the liquid collection bag. The interface can be connected to the existing disposable drainage bag. When the liquid collection bag is full, the exudate is discharged into the drainage bag, avoiding damage or irritation to the wound caused by frequent replacement of the liquid collection bag, which has the effect of reducing the discomfort of the patient and the workload of medical staff;

[0022] 2. The opening ends of the first valve and the second valve are both facing the interface end, and the first valve and the second valve divide the liquid collecting bag into two parts, an upper part and an lower part. When the exudate enters the upper part of the liquid collecting bag along the drainage tube wall, the first bag-shaped valve and the second bag-shaped valve are both attached to the inner wall of the liquid collecting bag under the pressure of the exudate, so that the exudate flows smoothly to the lower part of the liquid collecting bag. When the exudate refluxes, the exudate will flow into the valve through the opening ends of the first bag-shaped valve and the second bag-shaped valve. The first bag-shaped valve and the second bag-shaped valve are filled and expanded, and the outer surfaces of the first bag-shaped valve and the second bag-shaped valve will fit together, playing a cut-off role, and the refluxed exudate is cut off at the lower part of the liquid collecting bag, so as to prevent the exudate from continuing to flow back toward the central circular hole end and causing irritation to the wound;

[0023] 3. The drainage tube tunnel is made of soft rubber material, which can produce a certain adsorption force on the drainage tube, thereby maintaining the airtightness of the collection bag when the drainage tube passes through, preventing external bacteria from entering the collection bag and causing wound infection. The original state of the inlet and outlet is closed. When the collection bag is used on a wound without a drainage tube, it does not affect the airtightness of the collection bag. When the collection bag is used on a wound with a drainage tube, the inlet and outlet can be torn open along the tearable pressure mark to allow the drainage tube to pass through it; in addition, when some surgical wounds require negative pressure protection to promote healing, the negative pressure suction tube can be passed into the collection bag from the outlet and the inlet in turn, and the external negative pressure is attracted to form a negative pressure environment in the collection bag.

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] The present application embodiment discloses a wound drainage tube periphery anti-reflux liquid collection device. Figure 1 and Figure 2 The liquid collecting device comprises a liquid collecting bag 1, which is made of a transparent material. A scale line 13 and a colorimetric card 14 are arranged on the surface of the liquid collecting bag 1. A central circular hole 2 is opened on the top of the liquid collecting bag 1. An adhesive base is arranged on the periphery of the central circular hole 2. A ring-shaped chlorhexidine gluconate antibacterial gel 5 is arranged on the side of the adhesive base in contact with the skin. An adhesive glue 6 is arranged on the periphery of the antibacterial gel 5. An interface 3 is arranged on the bottom of the liquid collecting bag 1. A valve 4 is arranged on the interface 3. An anti-reflux component is fixedly arranged inside the liquid collecting bag 1. The adhesive glue 6 can adhere the liquid collecting bag 1 to the skin around the patient's wound. A drainage tube passes through the central circular hole 2. The central circular hole 2 can be cut according to the size of the wound and the position of the drainage tube, thereby improving the practicality of the liquid collecting bag 1. The exudate around the drainage tube flows into the liquid collecting bag 1 along the wall of the drainage tube and flows into the bottom of the liquid collecting bag 1 through the anti-reflux component. The anti-reflux component can prevent the exudate from flowing back to the wound. An interface 3 and a valve 4 are provided at the bottom of the liquid collecting bag 1. The valve 4 controls the switch of the outlet 11 of the liquid collecting bag 1. The interface 3 can be connected to an existing disposable drainage bag. When the liquid collecting bag 1 is full, the exudate is discharged into the drainage bag to avoid damage or irritation to the wound caused by frequent replacement of the liquid collecting bag 1.

[0029] Reference Figure 2The anti-reflux component is a bag-shaped valve group, which divides the liquid collecting bag 1 into two parts, the upper and lower parts. The bag-shaped valve group is composed of a first valve 7 and a second valve 8. The first valve 7 and the second valve 8 are symmetrically arranged with respect to the longitudinal axis of the liquid collecting bag 1. The opening ends of the first valve 7 and the second valve 8 are both facing the interface 3. When the exudate enters the upper part of the liquid collecting bag 1 along the drainage tube wall, under the action of the pressure of the exudate, the first bag-shaped valve and the second bag-shaped valve are both attached to the inner wall of the liquid collecting bag 1, so that the exudate can flow smoothly to the lower part of the liquid collecting bag 1. When the exudate refluxes, the exudate will flow into the valve through the opening end of the first bag-shaped valve and the opening end of the second bag-shaped valve. The first bag-shaped valve and the second bag-shaped valve are filled and expanded, and the outer surfaces of the first bag-shaped valve and the second bag-shaped valve will fit together, playing a cut-off role, and the refluxed exudate is cut off at the lower part of the liquid collecting bag 1, so as to achieve the purpose of preventing the exudate from continuing to flow back toward the end of the central circular hole 2 and causing irritation to the wound.

[0030] Reference Figure 1 and Figure 2 A drainage tube tunnel 9 is provided inside the liquid collecting bag 1, and the drainage tube tunnel 9 is provided at the upper part of the liquid collecting bag 1. An inlet 10 and an outlet 11 are provided at both ends of the drainage tube tunnel 9, respectively. The outlet 11 is fixedly connected to the side wall of the liquid collecting bag 1, and the inlet 10 is provided inside the liquid collecting bag 1. The drainage tube extends into the liquid collecting bag 1 through the central circular hole 2, and then passes through the drainage tube tunnel 9, and extends out of the liquid collecting bag 1 from the outlet 11 of the drainage tube tunnel 9, and is externally connected to a disposable drainage bag. The drainage fluid inside the drainage tube enters the disposable drainage bag, and the exudate around the drainage tube enters the liquid collecting bag 1;

[0031] The drainage tube tunnel 9 is made of soft rubber material, which can produce a certain adsorption force on the drainage tube, thereby maintaining the airtightness of the liquid collecting bag 1 when the drainage tube passes through, preventing external bacteria from entering the liquid collecting bag 1 and causing wound infection. The original state of the inlet 10 and the outlet 11 is closed, and the inlet 10 and the outlet 11 are both provided with a tearable pressure mark 12. When the liquid collecting bag 1 is used on a wound without a drainage tube, the airtightness of the liquid collecting bag 1 is not affected. When the liquid collecting bag 1 is used on a wound with a drainage tube, the inlet 10 and the outlet 11 can be torn open along the tearable pressure mark 12 to allow the drainage tube to pass through it; in addition, when some surgical wounds require negative pressure protection to promote healing, the negative pressure suction tube can be inserted into the liquid collecting bag 1 from the outlet 11 and the inlet 10 in turn, and the external negative pressure is attracted to form a negative pressure environment in the liquid collecting bag 1.

[0032] The implementation principle of the anti-reflux liquid collection device around the wound drainage tube of the embodiment of the present application is as follows: the liquid collection bag 1 is adhered to the skin around the patient's wound by adhesive 6, the drainage tube passes through the central circular hole 2 and extends into the liquid collection bag 1, the tearable pressure marks 12 at the inlet 10 and the outlet 11 of the drainage tube tunnel 9 are torn off, so that the drainage tube passes through the drainage tube tunnel 9 and extends out of the liquid collection bag 1 from the outlet 11 of the drainage tube tunnel 9, the drainage tube is externally connected to a disposable drainage bag, the drainage fluid inside the drainage tube enters the disposable drainage bag, and the exudate around the drainage tube enters the liquid collection bag 1;

[0033] The exudate around the drainage tube flows into the liquid collecting bag 1 along the wall of the drainage tube. Under the pressure of the exudate, the first bag-shaped valve and the second bag-shaped valve are both attached to the inner wall of the liquid collecting bag 1, so that the exudate flows smoothly to the lower part of the liquid collecting bag 1. When the exudate refluxes, the exudate flows into the valve through the opening end of the first bag-shaped valve and the opening end of the second bag-shaped valve. The first bag-shaped valve and the second bag-shaped valve are filled and expanded, and the outer surfaces of the first bag-shaped valve and the second bag-shaped valve are attached to each other, which plays a blocking role and stops the refluxed exudate at the lower part of the liquid collecting bag 1.

[0034] The bottom of the liquid collecting bag 1 is provided with an interface 3 and a valve 4, the valve 4 controls the switch of the outlet 11 of the liquid collecting bag 1, and the interface 3 is connected to the existing disposable drainage bag, and when the liquid collecting bag 1 is full, the exudate is discharged into the drainage bag.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes.
