Description

Technical Field

[0001] The utility model belongs to the technical field of drainage equipment and relates to a multifunctional negative pressure drainage ball. Background Art

[0002] The negative pressure drainage ball is a commonly used drainage device in surgical operations, which is used to observe and drain exudation from the surgical area / wound surface, or to drain purulent / necrotic materials in some clinical scenarios (such as parapharyngeal space infection and neck infection). When draining purulent / necrotic materials, due to the viscosity or separation of the drainage material, insufficient drainage or blockage of the drainage tube of the negative pressure ball may occur. Since the placement of the negative pressure ball is performed during surgery, if the drainage tube of the negative pressure ball is blocked, it cannot be replaced in time, resulting in even more insufficient drainage. The solution to this problem is to make the drainage smoother through local flushing. On the other hand, in the above clinical scenarios, it may not be possible to detect drainage tube blockage in a timely and early manner, and the increase in drainage tube pressure is a very early warning of blockage.

[0003] For example, Chinese patent application CN104353174A discloses an assembled negative pressure drainage ball, which includes a drainage ball and a drainage tube. The upper end of the drainage ball is provided with a joint, the lower end is provided with a negative pressure drainage hole, and the negative pressure drainage hole is provided with a negative pressure drainage cover; one end of the drainage tube is provided with a negative pressure joint, the drainage tube above the negative pressure joint is provided with a flushing joint, and the drainage tube above the flushing joint is provided with a fixing ear to prevent the drainage tube from slipping out of the wound; the joint at the upper end of the drainage ball is connected to the negative pressure joint of the drainage tube. This patent can achieve negative pressure drainage to a certain extent, but after research and analysis, it still has the following defects: 1. The negative pressure ball drains through a single opening, and the drainage effect is not sufficient; 2. The angle between its side road and the main road is large, and it is easy to backflow into the negative pressure ball during flushing; 3. Once blockage occurs, it is difficult to detect early.

[0004] Therefore, there is an urgent need for a multifunctional negative pressure drainage ball in clinical practice. On the one hand, when necessary, it can perform drainage while rinsing the surgical wound, thereby achieving an effective and complete drainage effect; on the other hand, it can detect the increase in drainage pressure (such as drainage tube blockage or increased material in the drainage site) at an early stage through a pressure detection device. Utility Model Content

[0005] The purpose of the utility model is to provide a multifunctional negative pressure drainage ball. On the one hand, when the drainage material is relatively viscous and difficult to drain or blocks the drainage tube, it can achieve the effect of effective and sufficient drainage by flushing the drainage area while draining; on the other hand, the pressure detection device can be used to detect the increase in pressure at the drainage point at an early stage, so as to detect clinical conditions that may need timely treatment at an early stage.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A multifunctional negative pressure drainage ball comprises a negative pressure ball, a drainage tube, and a flushing pipeline, wherein one end of the drainage tube is connected to the negative pressure ball, and the other end serves as a drainage port and is used to be placed in a drainage area for drainage, the flushing pipeline is connected to the side of the drainage tube, and also comprises a pressure detection device, which is composed of a pressure probe and a pressure connector connected to each other, wherein the pressure probe is located at the drainage port of the drainage tube and is used to detect the pressure condition in the drainage area, and the pressure connector extends out of the drainage tube and is used to connect to an external pressure monitoring device.

[0008] Furthermore, the drainage tube is processed with a side opening on the side wall near the drainage port.

[0009] Furthermore, there are a plurality of side openings.

[0010] Furthermore, the flushing pipeline is inclined toward the negative pressure ball, and the angle between the flushing pipeline and the drainage tube is 10 to 30 degrees.

[0011] Furthermore, one end of the flushing pipeline away from the drainage tube serves as a flushing liquid injection port, and a one-way valve is also provided at the flushing liquid injection port.

[0012] Furthermore, the negative pressure ball and the drainage tube are connected via a connecting tube.

[0013] Furthermore, a vascular clamp capable of cutting off blood flow is provided at the connecting tube.

[0014] Furthermore, the connecting tube is a rubber tube.

[0015] Furthermore, a wiring opening is provided on the side wall of the drainage tube, and the connection line between the pressure connector and the pressure probe passes through the wiring opening, and a sealing ring is also provided at the wiring opening.

[0016] Furthermore, the negative pressure ball is provided with an openable and closable discharge port.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] (1) Flushing fluid (such as saline or sterile water for injection) can be injected into the flushing pipeline to dredge the pipeline or fully drain out viscous and difficult-to-drain substances after flushing;

[0019] (2) A one-way valve for one-way flow is provided on the flushing liquid injection port of the flushing pipeline, so that when water is injected into it, the liquid can enter the drainage pipeline without flushing so that the piston can block the liquid from flowing out;

[0020] (3) Currently, if you want to inject into the drainage tube for flushing, you need to remove the connection device between the drainage tube and the negative pressure ball, and then connect it after the injection is completed. In this way, the size of the syringe and the size of the drainage tube do not match, which will cause the drainage tube to be exposed to the external environment. The utility model can effectively avoid the state where the drainage tube is exposed to the external environment;

[0021] (4) Monitor the pressure at the drainage site in real time. If the pressure rises significantly, find the cause in time, such as pathological increase in drainage volume or blockage of the drainage tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0026] In the following implementation manners or examples, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0027] In order to solve the problem of early blockage of the drainage tube 10 and improve the drainage effect, the utility model provides a multifunctional negative pressure drainage ball, the structure of which can be seen in Figure 1 As shown, it includes a negative pressure ball 6, a drainage tube 10, and a flushing pipeline 4. One end of the drainage tube 10 is connected to the negative pressure ball 6, and the other end serves as a drainage port 1 and is used to be placed in the drainage area for drainage. The flushing pipeline 4 is connected to the side of the drainage tube 10, and also includes a pressure detection device 8. The pressure detection device 8 is composed of a pressure probe 81 and a pressure connector 82 that are connected to each other, wherein the pressure probe 81 is located at the drainage port 1 of the drainage tube 10 and is used to detect the pressure condition of the drainage area, and the pressure connector 82 extends out of the drainage tube 10 and is used to connect an external pressure monitoring device.

[0028] When working, the negative pressure drainage ball of the utility model can, on the one hand, achieve effective and sufficient drainage by flushing the drainage area while draining when the drainage material is relatively viscous and difficult to drain or blocks the drainage tube 10; on the other hand, it can detect the increase in pressure at the drainage point through the pressure detection device 8 at an early stage, so as to detect clinical conditions that may need timely treatment at an early stage.

[0029] In some specific embodiments, the drainage tube 10 is also processed with a side opening 2 on the side wall near the drainage port 1. This part of the measurement and control opening is evenly arranged around the central axis of the drainage tube 10 in the area near the drainage port 1. It is also located in the drainage area during operation to assist drainage. Furthermore, there are a plurality of side openings 2. At this time, the pressure probe 81 can be fixed to the area of ​​the drainage tube 10 where the side opening is not arranged by gluing or other methods.

[0030] In some specific embodiments, the flushing pipeline 4 is inclined toward the negative pressure ball 6, and the angle between the flushing pipeline 4 and the drainage tube 10 is 10 to 30 degrees. This arrangement at a smaller angle allows the flushing liquid to enter the drainage area more smoothly and conveniently for flushing when the flushing pipeline 4 is injected with flushing liquid, thereby eliminating problems such as pipeline blockage and reducing the possibility of flowing into the negative pressure ball 6, thereby improving the flushing effect.

[0031] In some specific embodiments, one end of the flushing pipeline 4 away from the drainage tube 10 serves as a flushing liquid injection port, and a one-way valve 5 is also provided at the flushing liquid injection port. Flushing liquid is injected into the one-way valve 5 through a syringe. Under normal circumstances, the one-way valve 5 is in a closed state and no liquid will flow back out.

[0032] In some specific embodiments, the negative pressure ball 6 is connected to the drainage tube 10 through the connecting tube 3, and the connecting tube 3 is preferably made of soft material. Different from the conventional method of directly connecting the negative pressure ball 6 to the drainage tube 10, the utility model is preferably provided with a vascular clamp that can cut off the circulation at the connecting tube 3. When flushing is required, the vascular clamp can be used to clamp the connecting tube 3 to cut off the connection between the drainage tube 10 and the negative pressure ball 6 to prevent the flushing liquid from entering the negative pressure ball 6, thereby improving the flushing effect; and during drainage work, the vascular clamp is loosened, and the drainage tube 10 and the negative pressure ball 6 are normally connected for drainage. In addition, when flushing is performed, the flexible and deformable connecting tube 3 can also facilitate the adjustment of the angle between the drainage tube 10 and the negative pressure ball 6 to avoid interference between the flushing equipment and the negative pressure ball 6.

[0033] In some specific implementations, the connecting tube 3 is a rubber tube.

[0034] In some specific embodiments, the side wall of the drainage tube 10 is also provided with a wiring opening 9, and the connection line between the pressure connector 82 and the pressure probe 81 passes through the wiring opening 9. A sealing ring is also provided at the wiring opening 9. The connection of the pressure detection device 8 can be led out through the arrangement of this wiring opening 9, and the sealing ring can ensure the sealing and leakage-proof effect of the wiring opening 9 area.

[0035] In some specific implementations, the negative pressure ball 6 is further provided with an openable and closable discharge port 7, which can pour out the liquid and create a negative pressure state.

[0036] The above embodiments may be implemented individually or in any combination of two or more.

[0037] The above implementation is described in more detail below in conjunction with specific examples.

[0038] Embodiment 1:

[0039] In order to solve the problem of early blockage of the drainage tube 10 and improve the drainage effect, this embodiment provides a multifunctional negative pressure drainage ball, the structure of which can be seen in Figure 1 As shown, it includes a negative pressure ball 6, a drainage tube 10, and a flushing pipeline 4. One end of the drainage tube 10 is connected to the negative pressure ball 6, and the other end is used as a drainage port 1 and is placed in the drainage area for drainage. The flushing pipeline 4 is connected to the side of the drainage tube 10. It also includes a pressure detection device 8, which is composed of a pressure probe 81 and a pressure connector 82 that are connected to each other. The pressure probe 81 is fixed at the drainage port 1 of the drainage tube 10 (specifically, the area without the side opening 2) and is used to detect the pressure in the drainage area. The pressure connector 82 extends out of the drainage tube 10 and is used to connect to an external pressure monitoring device. The pressure probe 81 and the pressure connector 82 here are all conventional pressure detection structures in the field, and are not the innovation of the present utility model.

[0040] Please see again Figure 1As shown, the drainage tube 10 is also processed with a side opening 2 on the side wall near the drainage port 1. This part of the measurement and control opening is evenly arranged around the central axis of the drainage tube 10 in the area near the drainage port 1. It is also located in the drainage area when working to assist drainage. The flushing pipeline 4 is inclined toward the negative pressure ball 6, and the angle between the flushing pipeline 4 and the drainage tube 10 is 10-30°. This arrangement with a smaller angle allows the flushing pipeline 4 to enter the drainage area more smoothly and conveniently for flushing when the flushing liquid is injected into the flushing pipeline 4, so as to eliminate problems such as pipeline blockage and reduce the possibility of flowing into the negative pressure ball 6, thereby improving the flushing effect. The end of the flushing pipeline 4 away from the drainage tube 10 is used as a flushing liquid injection port, and a one-way valve 5 is also arranged at the flushing liquid injection port. The flushing liquid is injected into the one-way valve 5 through a syringe. Under normal conditions, the one-way valve 5 is in a closed state and no liquid will flow back out.

[0041] The negative pressure ball 6 is connected to the drainage tube 10 via a connecting tube 3 (a rubber tube is used in this embodiment), and a vascular clamp that can cut off the flow is also provided at the connecting tube 3. When flushing is required, the vascular clamp can be used to clamp the connecting tube 3 to cut off the connection between the drainage tube 10 and the negative pressure ball 6 to prevent the flushing liquid from entering the negative pressure ball 6, thereby improving the flushing effect; and during drainage work, the vascular clamp is loosened, and the drainage tube 10 and the negative pressure ball 6 are normally connected for drainage.

[0042] The side wall of the drainage tube 10 is also provided with a wiring opening 9, and the connection line between the pressure connector 82 and the pressure probe 81 passes through the wiring opening 9. A sealing ring is also provided at the wiring opening 9. The connection of the pressure detection device 8 can be led out through the arrangement of the wiring opening 9, and the sealing ring can ensure the sealing and leak-proof effect of the wiring opening 9 area. The negative pressure ball 6 is also provided with an openable and closable discharge port 7, which can pour out the liquid and create a negative pressure state.

[0043] When working, the negative pressure drainage ball of this embodiment can be used for drainage of the surgical area or wound surface. In some special cases, such as parapharyngeal space infection or neck abscess, when a drainage ball is placed, the drainage tube 10 will be blocked due to the excessive viscosity of the drainage material or the presence of blood clots, resulting in poor drainage. At this time, it is necessary to flush before drainage. When using the flushing function, a vascular clamp is first clamped at the connecting tube 3, so that with the flushing pipeline 4 arranged at a special angle, it can be ensured that the injected flushing liquid completely enters the surgical area / wound surface of the drainage tube 10 for effective flushing; after the liquid completely enters the wound surface, the vascular clamp is opened to allow the liquid to enter the negative pressure ball 6 and flow out, thereby playing an effective flushing role.

[0044] At the same time, during the entire working process, this embodiment is also equipped with a pressure detection device 8, whose pressure probe 81 is located at the drainage point, and the pressure connector 82 is located outside the drainage tube 10. The pressure connector 82 is connected to external pressure sensors and other monitoring equipment, and can monitor the pressure at the drainage point in real time. If the pressure rises significantly, it will serve as an early warning to observe whether there is a significant increase in drainage volume or blockage of the drainage tube 10.

[0045] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
