Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a device for precise measurement and drainage of wound exudate. Background Technology

[0002] Exudate refers to the fluid that seeps from a wound when the epithelial tissue in certain parts of the body becomes diseased. Many parts of the body can produce exudate due to disease, such as skin tissue, peritoneum, and the lining of joint cavities. A variety of diseases can cause exudate production in epithelial tissues, including trauma, inflammation, allergies, and tumors.

[0003] Authorization announcement number CN209500379U discloses a body fluid drainage device capable of accurately measuring and controlling drainage rate. The device includes a puncture tube, with a connecting tube, a first drainage tube, a Murphy drip tube, a second drainage tube, and a drainage bag arranged sequentially from top to bottom at the lower end of the puncture tube. While it can drain and measure exudate during use, it has shortcomings. Wound exudate often carries necrotic tissue or fibrin clots during drainage, easily causing blockage of the drainage tube lumen and resulting in poor drainage. This blockage not only affects the normal drainage of exudate, causing local fluid accumulation and delaying wound healing, but may also affect the accuracy of exudate measurement, thereby interfering with clinical assessment and treatment decisions. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems of the above-mentioned wound exudate accurate measurement and drainage device, this utility model is proposed.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a device for accurate measurement and drainage of wound exudate, including a drainage bottle with external graduations, and a drainage tube, a temporary storage bag and a connecting tube with a collection bag connected sequentially above the drainage bottle;

[0007] It also includes an injection tube connected to the top of the temporary storage bladder and parallel to the bottom of the connecting tube. The connecting tube and the injection tube are fixed with the same support plate. A turntable is rotatably connected to the center of the support plate via a rotating shaft. The turntable has a switching port, which consists of an arc hole centered on the rotating shaft and two circular holes 1 connected to the two ends of the arc hole 1. When the connecting tube is located in the arc hole 1, the internal flow channel is squeezed and closed by the arc hole 1. At this time, the injection tube is located in the corresponding circular hole 1, and the internal flow channel is open. Conversely, when the injection tube is located in the arc hole 1, the internal flow channel is squeezed and closed by the arc hole 1. At this time, the connecting tube is located in the circular hole 1 on the other side. The switching port can selectively switch the relative position of the arc hole 1 with the connecting tube and the injection tube by rotating the turntable.

[0008] As a preferred embodiment of the wound exudate precise measurement and drainage device of this utility model, a chuck is rotatably connected to the rotating shaft above the turntable. The chuck has a clamping opening, which is composed of a circular hole and an arc hole, and the connecting tube is located inside the circular hole.

[0009] As a preferred embodiment of the wound exudate precision measurement and drainage device of this utility model, the size of the first circular hole is the same as that of the second circular hole, and its size is larger than that of the connecting tube.

[0010] As a preferred embodiment of the wound exudate precision measurement and drainage device of this utility model, the turntable is provided with several recesses around its outer perimeter.

[0011] As a preferred embodiment of the wound exudate precision measurement and drainage device of this utility model, a protrusion is fixedly connected to the top of the chuck.

[0012] As a preferred embodiment of the wound exudate precise measurement and drainage device of this utility model, the top of the drainage bottle is connected to an exhaust pipe.

[0013] The beneficial effects of this utility model are:

[0014] 1. The temporary storage bladder can store exudate when the drainage tube is blocked, ensuring timely drainage of wound exudate and preventing local fluid accumulation. Simultaneously, through the coordination of the injection tube and the rotary table, flushing fluid or gas can be injected into the temporary storage bladder to flush or pressurize the inside of the drainage tube, forcing any blockages into the drainage bottle, thereby improving the drainage efficiency of the exudate.

[0015] 2. By using the turntable and chuck together, the internal flow channels of the connecting tube and the injection tube can be closed. At this time, squeezing the temporary storage bladder allows the seepage inside it and the seepage inside the drainage tube to quickly enter the drainage bottle, thereby enabling accurate measurement of the seepage flow rate and improving the accuracy of the data.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] Reference Figures 1-4 This invention provides a device for precise measurement and drainage of wound exudate, comprising a drainage bottle 1 with external graduations, an exhaust pipe 11 connected to the top of the drainage bottle 1, a drainage tube 2, a temporary storage bag 3 and a connecting tube 4 with a collection bag 41 connected sequentially above the drainage bottle 1. One end of the connecting tube 4 is inserted into the deep part of the wound or into the relevant tissue or body cavity adjacent to the wound through surgical operation, so that the opening end of the connecting tube 4 is precisely located in the area that needs drainage, ensuring that the exudate from the wound can be effectively collected and drained. In actual use, the drainage tube 2 is in a vertical state to avoid bending that would cause the exudate to flow poorly. The collection bag 41 is located in the middle and slightly below the connecting tube 4.

[0027] like Figure 2 and Figure 3 As shown, it also includes an injection tube 5 connected to the top of the temporary storage bladder 3 and parallel to the bottom of the connecting tube 4. The same support plate 6 is fixed to both the connecting tube 4 and the injection tube 5. A turntable 7 is rotatably connected to the center of the support plate 6 via a rotating shaft 61. A switching port 71 is provided on the turntable 7. The switching port 71 consists of an arc hole centered on the rotating shaft 61 and two circular holes 1 connecting the two ends of the arc hole 1. The arc hole 1 and the circular holes 1 form a continuous channel. When the connecting tube 4 is located inside the arc hole 1, the internal flow channel is compressed and closed by the arc hole 1. When the injection tube 5 is located in the corresponding circular hole 1, the internal flow channel is open; conversely, when the injection tube 5 is located in the arc hole 1, the internal flow channel is closed by the pressure of the arc hole 1, and the connecting tube 4 is located in the circular hole 1 on the other side; and the switching port 71 is controlled by the rotation of the turntable 7 to selectively switch the relative positions of the arc hole 1, the connecting tube 4 and the injection tube 5. Under the adjustment of the switching port 71, the connecting tube 4 and the drainage hose 2 always maintain an open and closed state, and in the initial state, the connecting tube 4 is in the open state and the injection tube 5 is in the closed state.

[0028] A chuck 8 is rotatably connected to the rotating shaft 61 above the turntable 7. Both the turntable 7 and the chuck 8 can rotate independently. The chuck 8 has a clamping opening 81, which consists of a connected circular hole 2 and an arc hole 2. The connecting tube 4 is located inside the circular hole 2. The opening and closing state of the connecting tube 4 can be controlled through the clamping opening 81. The size of the circular hole 1 is the same as that of the circular hole 2, and its size is larger than that of the connecting tube 4. Several notches are opened around the outside of the turntable 7. The notches make the outer contour of the turntable 7 rough, making it easy to rotate the turntable 7. A protrusion is fixedly connected to the top of the chuck 8, which makes it easy to pull the chuck 8 to rotate.

[0029] Working principle: During the process of wound exudate entering the drainage bottle 1 through the connecting tube 4, temporary storage sac 3, and drainage tubing 2, tissue fragments and clots in the exudate can easily clog the drainage tubing 2, and the exudate will accumulate in the temporary storage sac 3. At this time, medical staff can turn the turntable 7 so that the arc hole of the switching port 71 squeezes the connecting tube 4, and the injection tube 5 is located in the round hole. At this time, the injection tube 5 can be injected into the temporary storage sac 3 through the syringe connected to the injection tube 5. The irrigation fluid can flush the inner wall of the drainage tubing 2, reduce bacterial growth, and flush its inner wall, pushing the blockage into the drainage bottle 1; the gas can pressurize the inside of the temporary storage sac 3 and the drainage tubing 2, and push the blockage into the drainage bottle 1 through the pressure difference, completing the anti-blockage operation of the drainage tubing 2. At this time, turning the turntable 7 in the opposite direction can keep the connecting tube 4 connected and close the injection tube 5.

[0030] When it is necessary to measure the seepage, simply pull the chuck 8 to rotate by the convex tab, so that the arc hole 2 on the clamp 81 squeezes the connecting tube 4, so that it and the injection tube 5 are both in a closed state. Then, squeeze the temporary storage bag 3 to squeeze the seepage remaining in the drainage tube 2 into the drainage bottle 1. At this time, the amount of seepage can be accurately read by the scale. In addition, if there is flushing fluid in the drainage bottle 1, the amount of flushing fluid needs to be subtracted. The amount of flushing fluid can be determined by the scale of the syringe.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
