Description

Technical Field

[0001] The utility model relates to a bile filtering and tube feeding integrated infuser, belonging to the technical field of medical equipment. Background Art

[0002] Biliary tract surgery often requires bile reinfusion, which allows drained bile to be reused by the body, reducing fluid loss, restoring the enterohepatic circulation of bile salts, and maximizing their original physiological functions. Traditional tube feeding for bile reinfusion requires a variety of items, including a homemade simple filter cup, measuring cup, paper cup, gauze, rubber band, and syringe. First, a measuring cup is used to collect and measure the bile to be reinfused from the drainage bag. Then, 4-6 layers of gauze are placed on the mouth of the paper cup and secured with a rubber band to create a filter. Finally, the bile in the measuring cup is filtered to remove flocculent matter, aspirated with a syringe, and reinfused through tube feeding.

[0003] The above-mentioned disadvantages of traditional tube feeding and bile reinfusion:

[0004] 1. Traditional bile tube feeding requires bile to be transferred to different containers. Bile is measured in a measuring cup, filtered in a paper cup, and then infused back into the body using a syringe. Frequent container changes increase the risk of contamination.

[0005] 2. The homemade filtering device has no support under the gauze and cannot hold liquid. For bile that is viscous and has a lot of flocs, the bile is likely to flow out along the wall of the cup during the filtration process.

[0006] 3. The operation steps are complicated. Utility Model Content

[0007] The technical problem to be solved by the utility model is: how to simplify the operation steps of filtering bile and perfusing and reinfusing bile.

The food-grade temperature-resistant transparent material meets the general requirements of bile heating.

[0024] The utility model is used for bile tube feeding, bile filtration and pipetting, syringe suction and other processes. The utility model combines bile filtration with the syringe, and the tube feeding operation can be performed after bile filtration. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 This is a schematic diagram of a bile filtration and tube feeding integrated perfusion device. DETAILED DESCRIPTION

[0026] In order to make the present invention more clear and easy to understand, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0027] The utility model provides a bile filtration and tube feeding integrated perfusion device, such as Figure 1 As shown, it includes a filter cup body 4 and an infusion cylinder body 5, which are connected by a partition cavity. A partition 12 that can move up and down is provided in the partition cavity. The partition 12 is matched and inserted in the partition cavity. A filter cup hole 9 (i.e., the bile outlet of the filter cup body 4) is provided on the side of the filter cup body 4 close to the infusion cylinder body 5, and an infusion cylinder hole 7 (i.e., the bile inlet of the infusion cylinder body 5) is provided on the side of the infusion cylinder body 5 close to the filter cup body 4. The filter cup hole 9 and the infusion cylinder hole 7 are arranged opposite to each other, and a partition hole 8 is provided on the partition 12. When the partition 12 is inserted at the bottom of the partition cavity, the partition hole 8 is located below the filter cup hole 9 and the infusion cylinder hole 7, the cavity between the filter cup body 4 and the infusion cylinder body 5 is not connected, and the partition 12 separates the filter cup body 4 and the infusion cylinder body 5; when the partition 12 is pulled up, the partition hole 8 is located at the position of the filter cup hole 9 and the infusion cylinder hole 7, that is, the three holes (partition hole 8, filter cup hole 9, infusion cylinder hole 7) are coaxial, forming a filter cup-infusion cylinder connecting channel, so that the cavity of the filter cup body 4 and the infusion cylinder body 5 are connected.

[0028] The openings of both the filter cup body 4 and the infusion cartridge body 5 are located at the top. A sieve 1 covers the top opening of the filter cup body 4 (i.e., the bile inlet of the filter cup body 4). Four to six layers of sterile gauze are stacked on top of the sieve 1. A retractable injection piston 11 is installed within the infusion cartridge body 5. The maximum outer diameter of the injection piston 11 matches the inner diameter of the infusion cartridge body 5. The sieve 1 is placed over the opening of the filter cup body 4 and is removable, facilitating cleaning of the entire device. A raised portion on the side of the sieve serves as a grip.

[0029] The sidewall of the filter cup body 4 is provided with filter cup scale lines 3 for measuring the volume of the liquid (bile) within the filter cup body 4. The sidewall of the infusion cylinder body 5 is provided with infusion cylinder scale lines 10 for measuring the volume of the liquid (bile) within the infusion cylinder body 5. A handle 2 is provided on the outer sidewall of the filter cup body 4 or the infusion cylinder body 5 to facilitate handling of the entire device of the present invention. In this embodiment, the handle 2 is located on the side of the filter cup body 4. The sieve 1 has a funnel-shaped structure.

[0030] The filling cylinder body 5 is a cylindrical structure, the filter cup body 4 is a cylindrical structure with an arc-shaped notch on the side, the filling cylinder body 5 is arranged in the notch on the side of the filter cup body 4, the partition 12 is an arc-shaped structure, and the centers of the cross sections of the notch, the partition 12, and the filling cylinder body 5 are concentric circles.

[0031] An injection piston 11 is inserted into the infusion barrel body 5 from the top opening. When the filter cup body 4 and the infusion barrel body 5 are disconnected, the injection piston 11 moves toward the bottom of the infusion barrel body 5, allowing the liquid (bile) in the infusion barrel body 5 to flow out of the infusion outlet 6 at the bottom side of the infusion barrel body 5 (i.e., the bile outlet of the infusion barrel body 5). When the infusion outlet 6 is sealed and the filter cup body 4 and the infusion barrel body 5 are connected, the liquid (bile) in the filter cup body 4 enters the infusion barrel body 5. If the injection piston 11 moves away from the bottom of the infusion barrel body 5, the liquid (bile) in the filter cup body 4 enters the infusion barrel body 5 faster. The infusion outlet 6 includes a sealing plug.

[0032] The diameter of the infusion outlet 6 is smaller at the outlet than at the inlet, accommodating tube feedings of varying diameters. The infusion outlet 6 is positioned on the sidewall of the infusion barrel body 5, allowing the entire device to be positioned stably on a horizontal surface. The entire device is constructed of food-grade, heat-resistant, transparent materials, meeting the general requirements for bile heating.

[0033] The use process of this utility model is as follows:

[0034] Place the drainage bag outlet above the sieve 1, and bile flows into the filter cup body 4 through the sieve 1 until the required amount of bile for tube feeding is slightly more than required (the specific amount of bile can be known according to the scale line 3 on the filter cup). Ensure that the perfusion outlet head 6 is airtight, lift the partition 12 until the three holes (partition hole 8, filter cup hole 9, and perfusion cylinder hole 7) are coaxial, and bile flows into the perfusion cylinder body 5. Press the partition 12 to the bottom of the partition cavity, so that the filter cup body 4 and the perfusion cylinder body 5 are two separate containers. Confirm the perfusion amount again according to the scale line 10 on the perfusion cylinder, and press down the injection piston 11 to tube feed the bile in the perfusion cylinder body 5 (open the perfusion outlet head 6, and the bile can be discharged from the perfusion outlet head 6).
