Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a disc-shaped flushing and drainage device for skin and soft tissue infections. Background Technique

[0002] Subcutaneous soft tissue infections caused by various reasons such as superficial tissue injuries after trauma and neck anastomotic fistulas after esophageal cancer surgery are extremely common in clinics. At present, the common clinical treatment method is to strengthen dressing change to thoroughly drain the infection source. However, in actual use, the wound surface is drained by VSD, and the wound surface is sealed with a biological transparent film to form a closed drainage system. However, during the use process, as the exudate increases and dries up, it is easy to block the pores between the VSD sponges, resulting in the inability of the medical VSD to drain the exudate, making the VSD drainage unsmooth. Therefore, frequent dressing changes are required, increasing the labor cost. For this reason, we propose a disc-shaped flushing and drainage device for skin and soft tissue infections. Content of the Utility Model

[0003] The utility model aims to provide a disc-shaped flushing and drainage device for skin and soft tissue infections, which can continuously flush the infected wound, avoid high-frequency dressing changes by clinicians, and save labor costs.

[0004] For this reason, the technical solution adopted by the utility model is as follows:

[0005] A disc-shaped flushing and drainage device for skin and soft tissue infections, comprising:

[0006] A protective disc, an installation hole is opened at the center of the top of the protective disc, a protective plug is clamped inside the installation hole, at least two limiting holes are opened at the top of the protective plug, and a flushing tube and a drainage tube are respectively installed in the two limiting holes, and the top end of the flushing tube is connected to a flushing bag;

[0007] A drainage bottle, the drainage bottle is connected to the free end of the drainage tube, and a negative pressure pump is connected to the drainage bottle;

[0008] A chassis, the chassis is clamped at the bottom of the protective disc, a plurality of sealing grooves are opened at the top of the chassis, and the sealing grooves and the protective disc are mutually adapted.

[0009] Based on the above technical solution, its working principle and the technical effects produced are:

[0010] When it is necessary to flush the patient's wound, first select an appropriate protective tray according to the size of the patient's wound, then cut a chassis of appropriate size according to the size of the protective tray, then adhere the chassis to the outer surface of the patient's wound through medical glue, then pass the flushing tube and the drainage tube through the limiting holes and fix them at appropriate positions on the protective plug, and adjust the use lengths of the flushing tube and the drainage tube, then insert the flushing tube into the infected soft tissue and leave the drainage tube at the wound edge or the lower-lying part to facilitate flushing and drainage operations, then snap the protective plug into the installation hole, and then use the externally connected micro water pump to transport the flushing liquid in the flushing bag into the flushing tube, and the infected area of the patient's wound can be flushed and cleaned. Then, start the negative pressure pump to generate negative pressure in the drainage bottle, and the contaminated liquid flushed can be drained through the drainage tube. In this way, compared with the traditional VSD negative pressure drainage, it avoids the inability to drain residue-like pus through small apertures, facilitates improving the flushing efficiency, and will not cause leakage and pollution.

It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0034] Embodiment 1:

[0035] According to the concept of the present application, an embodiment of a skin and soft tissue infection disc type flushing and drainage device for flushing and cleaning a patient's wound infection is described herein in conjunction with Figures 1 to 4 Specifically, the skin and soft tissue infection disc type flushing and drainage device is configured as a split structure, and it has three components, namely a protective disc 1, a drainage bottle 8, and a chassis 10. Through the mutual cooperation of the structures such as the protective disc 1, the chassis 10, the flushing tube 5, and the drainage tube 6, the infection source can be effectively flushed, and at the same time, the negative pressure drainage can be avoided from damaging the patient's wound. Compared with the traditional method of using medical sponges to absorb exudate, the high-frequency dressing change by clinicians is avoided, the labor cost is saved, and through the mutual cooperation of the protective disc 1, the chassis 10, and the sealing groove 11, the sealing performance between the protective disc 1 and the chassis 10 can be enhanced, and the leakage of wound exudate and flushing sewage during the flushing and drainage process can be avoided, resulting in pollution and reducing the nursing workload.

[0036] Combined with Figures 1-4 As shown, the skin and soft tissue infection disc type flushing and drainage device provided by the present invention includes:

[0037] A protective disc 1, an installation hole 2 is opened at the center of the top of the protective disc 1, a protective plug 3 is clamped inside the installation hole 2, at least two limiting holes 4 are opened at the top of the protective plug 3, and a flushing tube 5 and a drainage tube 6 are respectively installed in the two limiting holes 4, and the top end of the flushing tube 5 is connected to a flushing bag 7;

[0038] A drainage bottle 8, the drainage bottle 8 is connected to the free end of the drainage tube 6, and a negative pressure pump 9 is connected to the drainage bottle 8;

[0039] A chassis 10, the chassis 10 is clamped at the bottom of the protective disc 1, a plurality of sealing grooves 11 are opened at the top of the chassis 10, and the sealing grooves 11 and the protective disc 1 are mutually adapted.

[0040] Regarding the technical solution of this embodiment, the protective disk 1 is made of a transparent material, and the cross-sectional shape of the protective disk 1 is set to be circular. The diameter of the bottom end of the protective disk 1 is larger than that of the top end. And in order to facilitate adaptation to different wound sizes, the protective disk 1 can be set in a variety of different sizes, such as a large disk with a bottom diameter of 15 cm, a medium disk with a bottom diameter of 10 cm, and a small disk with a bottom diameter of 5 cm. The specific size of the protective disk 1 in this embodiment is not limited and can be selected according to the situation during actual use.

[0041] Furthermore, the protective disk 1 is made of soft plastic, and the overall height of the protective disk 1 is 3 - 5 cm. The protective disk 1 made of soft plastic has a certain deformation ability, which is convenient for adapting to the skin curvature of different parts and improving the practicability of the device. And regarding the technical solution of this embodiment, the specific height of the protective disk 1 is not limited, as long as it meets a certain flushing and drainage space.

[0042] Regarding the technical solution of this embodiment, the diameter of the limiting hole 4 is equal to the outer diameters of the flushing tube 5 and the drainage tube 6. By using the provided limiting hole 4, it is convenient to limit the use length and layout position of the flushing tube 5 and the drainage tube 6, so that the flushing tube 5 extends into the infected soft tissue, and the drainage tube 6 remains at the wound edge or the dependent part, thus facilitating the flushing and drainage operations.

[0043] Regarding the technical solution of this embodiment, the overall shape of the protective plug 3 is frustum-shaped, and the inner wall of the mounting hole 2 is adapted to the outer surface of the protective plug 3. The protective plug 3 is made of silica gel material, and a ventilation hole 12 is also provided at the top of the protective plug 3. By using the provided protective plug 3, it is convenient to install and position the flushing tube 5 and the drainage tube 6 during flushing and drainage. And when the protective plug 3 is stuck in the mounting hole 2, the sealing performance between it and the mounting hole 2 is good. And when the protective plug 3 is installed in the mounting hole 2, the top plane of it is higher than the top plane of the protective disk 1, which is convenient for medical staff to pull out the protective plug 3 from the mounting hole 2.

[0044] Regarding the technical solution of this embodiment, a micro pump is connected to the flushing bag 7, and the micro pump is powered by an external power supply. During actual use, starting the micro pump can deliver the flushing liquid in the flushing bag 7 into the flushing tube 5, and then the infected area of the patient's wound can be flushed and cleaned. Or during actual use, it can be flushed manually by medical staff and the flushing flow rate can be controlled.

[0045] Regarding the technical solution of this embodiment, the chassis 10 is made of silica gel material. A medical adhesive layer is provided at the bottom of the chassis 10, which facilitates fixing the chassis 10 around the patient's wound by means of the provided medical adhesive layer. Moreover, a plurality of sealing grooves 11 are provided at the top of the chassis 10, and the diameter of each sealing groove 11 is not equal, mainly for adapting to protection discs 1 of different specifications and sizes. During actual use, according to the size of the patient's wound, the corresponding protection disc 1 is selected, and then the chassis 10 is cut, and the sealing groove 11 corresponding to the protection disc 1 is selected. It should be noted that since the chassis 10 is made of silica gel and the thickness of the chassis 10 is not large, it is convenient to cut it.

[0046] Regarding the technical solution of this embodiment, the width of the sealing groove 11 is equal to the thickness of the protection disc 1, and a plurality of bumps 13 are fixedly connected to the bottom of the outer edge of the protection disc 1. The plurality of bumps 13 are evenly arranged along the circumferential direction of the protection disc 1, and grooves adapted to the bumps 13 are provided on the inner side wall of the sealing groove 11. After the chassis 10 is fixed at the patient's wound, by inserting the bottom of the protection disc 1 into the sealing groove 11, a seal can be formed between the protection disc 1 and the chassis 10, avoiding liquid leakage during flushing and causing pollution to the patient's body and the hospital bed, reducing the nursing workload. Moreover, by inserting the provided bumps 13 into the grooves, it is also convenient to effectively fix the protection disc 1 on the chassis 10, enhancing the connection strength between the two and preventing the protection disc 1 from falling off the base, which will not only cause liquid leakage but also affect the normal flushing process.

[0047] Specifically, when it is necessary to flush the patient's wound, first, according to the size of the patient's wound, an appropriate protection disc 1 is selected, then an appropriately sized chassis 10 is cut according to the size of the protection disc 1, and then the chassis 10 is adhered to the outer surface of the patient's wound through medical glue. Then, the flushing tube 5 and the drainage tube 6 are passed through the limiting holes 4 and fixed at appropriate positions of the protection plug 3, and the use lengths of the flushing tube 5 and the drainage tube 6 are adjusted. Then, the flushing tube 5 is inserted into the infected soft tissue, and the drainage tube 6 is left at the wound edge or the lower-lying part, so as to facilitate flushing and drainage operations. Then, the protection plug 3 is inserted into the installation hole 2, and then the flushing liquid in the flushing bag 7 is conveyed into the flushing tube 5 through an externally connected micro water pump, and the infected part of the patient's wound can be flushed and cleaned. Then, by starting the negative pressure pump 9 to generate negative pressure in the drainage bottle 8, the contaminated liquid flushed can be drained through the drainage tube 6. In this way, compared with the traditional VSD negative pressure drainage, it avoids the small aperture being unable to drain the slag-like pus, facilitating the improvement of the flushing efficiency and preventing liquid leakage and pollution.
