Abstract
Description
Technical Field
[0001] The utility model relates to the field of connecting tubes, in particular to a medical multifunctional multi-cavity connecting tube. Background Art
[0002] Infectious pancreatic necrosis (IPN) is a deep soft tissue abscess, and dual-cannula continuous negative pressure irrigation and drainage is currently the preferred treatment. IPN patients often have abscesses of varying locations and sizes, and they may not be interconnected. Physicians will place multiple dual-cannulae based on the location of the abscess cavities, performing simultaneous continuous irrigation and negative pressure drainage to liquefy and dilute some of the necrotic tissue, facilitate pus drainage, and promote recovery. Simultaneous irrigation and aspiration of two abscess cavities requires two negative pressure aspiration devices and a negative pressure gauge. However, bedside equipment only has one negative pressure gauge port, which must be connected to the negative pressure port on the adjacent bed. This is inconvenient, clutters the bedside, wastes consumables, and is costly. When three or more abscess cavities require simultaneous irrigation, clinical needs are limited. To facilitate operation and meet clinical needs, disposable intravenous nutrition bags with multiple lumens are often used. Each cut requires sterile scissors and a connecting pipe joint. Each joint must be soaked in disinfectant and rinsed with saline before use. This not only wastes resources, delays time, and poses infection risks, but also significantly increases costs.
[0003] The prior art, "A Four-Chamber Drainage Tube Device with Flushing and Continuous Negative Pressure Suction," published in Publication No. CN209827713 U, includes a main tube and three branch tubes. The lower end of the main tube and the upper ends of the three branch tubes are each capped with a protective cap. The lower ends of the three branch tubes converge and connect to the upper end of the main tube. The interiors of the three branch tubes are all connected to the interior of the main tube. The inner diameter of the main tube is larger than the outer diameter of each branch tube. Both the three branch tubes and the main tube are equipped with removable tube clamps. This four-chamber drainage tube device with flushing and continuous negative pressure suction allows for both flushing and drainage, while also saving the cost of drainage bags.
[0004] However, when using existing technologies as drainage tubes, if the pus to be drained is relatively viscous, the tube must be removed from the drainage bag and connected to a negative pressure gauge, or removed from the drainage bag and connected to a flushing device before being removed and connected to the drainage bag for continued drainage. It is impossible to flush relatively viscous pus without removing the drainage tube. Furthermore, it is impossible to administer medication to the abscess cavity alone. Utility Model Content
[0005] The embodiment of the present application provides a medical multifunctional multi-lumen connecting tube, which solves the problem in the prior art that when the pus to be drained is relatively viscous, the drainage device needs to be removed and then connected, and flushing and drainage cannot be performed without removing the drainage device.
[0006] To solve the above technical problems, the present invention provides the following technical solution: a medical multifunctional multi-lumen connecting tube, comprising a connecting handle and a cavity, the ends of which are connected and internally communicated; the cavity comprises a plurality of cavity tubes, each of which is connected to the connecting handle and has an external port connected to the interior of the cavity tube. The external port connected to the cavity tube can be used to flush the patient's purulent area or administer medication separately, allowing relatively viscous pus to be diluted and flowed into a drainage bag without removing the drainage device.
[0007] As a preferred embodiment of the multifunctional multi-lumen connecting tube of the present invention, the connecting handle includes a connecting head and a connecting tube. The connecting head is an elastic ring-shaped part, and the connecting tube is connected to the cavity. The elastic connecting head can be conveniently connected to a negative pressure gauge or a drainage bag.
[0008] As a preferred embodiment of the multifunctional multi-lumen connecting tube of the present invention, a regulator is mounted on the cavity tube, located between the outer opening and the connecting handle. The regulator allows for controlled drainage speed as needed. Furthermore, when a wound needs to be irrigated or medication applied, closing the regulator allows the entire medication or irrigating solution to flow directly to the wound, avoiding waste.
[0009] As a preferred solution of the medical multifunctional multi-lumen connecting tube of the present invention, an interface is provided at the end of the cavity tube away from the connecting handle, and the connection interface is connected to an external instrument. The interface design facilitates connection to the abscess cavity tube.
[0010] As a preferred solution of the medical multifunctional multi-lumen connecting tube of the present invention, the interface is detachably connected to a plug, which is connected to an external device. Different plug shapes can be provided to connect different abscess tubes.
[0011] As a preferred solution of the medical multifunctional multi-lumen connecting tube of the present invention, an outer cover is provided on the interface, and the outer cover wraps the plug. The outer cover can protect the connector and / or the plug from contamination before use.
[0012] As a preferred embodiment of the medical multifunctional multi-lumen connecting tube of the present invention, a cap is provided on the outer opening to prevent pus from flowing out of the outer opening. Using the cap instead of medical tape for bonding is convenient and safe, and reduces the risk of infection for patients.
[0013] As a preferred embodiment of the multifunctional multi-lumen connecting tube for medical use described in this invention, the lumen tube can be made of materials such as polyvinyl chloride (PVC), polyethylene (PE), or high-performance polyolefin thermoplastic elastomer (TPE). Using medical-grade materials for the lumen tube reduces individual production costs and provides greater safety and stability.
[0014] One or more technical solutions are provided in the embodiments of the present application, which have at least the following technical effects or advantages:
[0015] 1. According to the number of abscess cavities of the patient, different numbers of cavity tubes can be flexibly selected and connected to the same drainage bag to improve the convenience of patient activities. The same negative pressure gauge can be connected to reduce the use of external equipment.
[0016] 2. It can realize the dual functions of flushing and drainage without disassembling the drainage device.
[0017] 3. By setting the connection port and plug, it can adapt to the interface of different drainage tubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0026] Reference Figure 1-4 , this embodiment provides a medical multifunctional multi-lumen connecting tube.
[0027] The multifunctional medical multi-lumen connecting tube comprises a connecting handle 1 and a cavity 2. Cavity 2 is primarily used to connect to a drainage tube (e.g., a pus cavity tube inserted into a patient's suppurative area) to drain pus from the patient's suppurative area. The connecting handle 1 is connected to an external device. When the multifunctional medical multi-lumen connecting tube is used as a drainage connecting tube, the end of the connecting handle 1 is connected to a drainage bag; when the multifunctional medical multi-lumen connecting tube is used as a negative pressure connecting tube, the end of the connecting handle 1 is connected to a negative pressure gauge.
[0028] Specifically, the connecting handle 1 includes a connecting head 11 and a connecting tube 12. The connecting head 11 is an annular elastic sheet, and the connecting tube 12 is a hollow thin-walled structure. The connecting head 11 and the connecting tube 12 are fixed by bonding or integrally formed.
[0029] The cavity 2 includes a plurality of cavity tubes 21, including at least 2 (different numbers can be set according to needs, such as Figure 4 As shown in FIG. 1 ), the number of cavity tubes 21 can be determined based on the number of purulent sites on the patient. Multiple cavity tubes 21 converge at the top and connect to the end of the connecting handle 1 away from the connector 11 at the convergence point. The top convergence point of the multiple cavity tubes 21 can be fixedly connected to the connecting handle 1 (bonding or integrally formed) or detachably connected (for example, by threading, sleeve fastening, etc.). The connecting tube 12 communicates with the internal spaces of the multiple cavity tubes 21.
[0030] When the connection is detachable, the connecting handle 1 can be universal, and it is only necessary to select a cavity 2 containing different numbers of cavity tubes 21 according to different needs.
[0031] An outer opening 212 is fixedly connected to each cavity tube 21. The outer opening 212 is a circular tube that connects the cavity tube 21 with the external space. Medication or flushing can be performed on the patient's purulent area through the outer opening 212. A cap (not shown in the figure) is provided on the outer opening to replace the tape to seal the outer opening 212 to prevent pus from flowing out of the outer opening 212 during drainage.
[0032] For ease of understanding, the following only takes the structure of a single cavity tube 21 as an example. The other cavity tubes 21 have the same structure as the cavity tube described. Figure 3-4 In the figure, only the specific structural arrangement of one cavity tube 21 is given in detail, and the structures of the other cavity tubes 21 are consistent with the cavity tube structure given in detail.
[0033] Furthermore, a regulator 211 is sleeved on the cavity tube 21 . The regulator 211 adopts the structure of an existing infusion tube regulator and can control the speed of pus drainage. The regulator 211 is located between the outer opening 212 and the connecting handle 1 .
[0034] A port 213 is provided at the end of the cavity tube 21, away from the connecting handle 1. Port 213 is internally threaded, and a plug 214 is connected to the cavity tube 21 via the threads of port 213. Plug 214 is a conical, hollow structure with threads on its surface. (If port 213 does not have internal threads, medical tape can be used to connect port 213 to the drainage tube; internal threads facilitate connection.)
[0035] An outer cover 215 is provided on the interface 213. The outer cover 215 can completely cover the plug 214, thereby protecting the interface of the connecting tube when not in use, avoiding contamination in the environment, and thus increasing the probability of inflammation in the patient when in use.
[0036] When the medical multifunctional multi-lumen connecting tube of the embodiment of the present application is a drainage connecting tube, the connector 11 is directly connected to a straight-end drainage bag. If the end of the drainage tube (abdominal tube) is a straight lumen, the plug 214 is removed and the drainage tube can be directly connected to the cavity tube 21 through the interface 213; if the end of the drainage tube is a screw-shaped one, the drainage tube can be connected to the cavity tube 21 through the plug 214. In this way, it can be connected to different abdominal drainage tubes, increasing the adaptability of the medical multifunctional multi-lumen connecting tube. During normal drainage, the cap of the outer opening 212 is tightly closed to prevent the abscess cavity fluid from overflowing from the outer opening 212. When the pus is too viscous and the drainage effect is poor, the regulator 211 can be closed and medication or flushing can be performed from the outer opening 212. After completion, the outer opening 212 is sealed with the cap, and the regulator 211 is opened again to continue draining the pus into the drainage bag. In this way, a multi-lumen drainage effect is achieved, and the tightness is good and the operation is convenient. Through the connecting tube of the utility model, only one drainage bag needs to be connected externally, which can reduce the number of external drainage bags, facilitate patients to get out of bed and move around, and promote comfort; on the other hand, it is convenient for observation and statistics of drainage fluid.
[0037] When the medical multifunctional multi-cavity connecting tube of the embodiment of the present application is a negative pressure connecting tube, the connector 11 is connected to the negative pressure gauge, the interface 213 or the plug 214 is connected to the drainage tube, the outer port 212 is blocked, and the regulator 211 on the cavity tube 21 is opened to form a negative pressure to achieve a continuous negative pressure effect. The regulator 211 can also be adjusted according to the viscosity and drainage volume of the drainage fluid in the patient's pus cavity to achieve the purpose of the lowest negative pressure and the best drainage effect. When multiple negative pressure suction devices are needed, this connecting tube can be used to connect multiple devices together in a sealed manner and share a negative pressure gauge for easy observation and care.
[0038] When it is necessary to apply medicine to the purulent area of the patient alone or the drainage fluid in the pus cavity is too viscous, the regulator 211 on the cavity tube 21 can be closed, and then the purulent area can be applied with medicine or flushed from the outer opening 212.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
