Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable drip rate colonic drip device. Background Technology

[0002] An enema is an external treatment method in which a medicinal solution is instilled into the rectum or colon and retained there for absorption through the intestinal mucosa to treat diseases. During this process, the appropriate drip rate is crucial; too fast and the solution is difficult to retain, too slow and it remains in place for too long, causing discomfort to the patient's intestines and anus. Furthermore, different individuals have different tolerance levels for drip rates; therefore, the speed of the colonic drip device needs to be adjusted during an enema.

[0003] Currently, commonly used colonic drip devices typically control the drip rate by using a roller to press the tubing. This involves a flow rate regulator on the drip line, which adjusts the pressure applied to the tubing by changing the roller's position, thus altering the flow area and resistance to regulate the drip rate. While this method allows for drip rate adjustment, the lack of a fixed setting makes it difficult to quickly and accurately reach the desired rate. The operator must estimate the rate beforehand by observing the medication flowing from the tubing or by observing the drip chamber on a portion of the tubing, then manually adjust the rate repeatedly to stabilize it. This process results in insufficient accuracy and slow adjustment speed.

[0004] Therefore, the current method of using roller pressure tube speed regulation is difficult to adjust the drip rate quickly and accurately due to the lack of graded speed settings, which makes it difficult to stabilize the dripping effect. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable drip rate colonic drip device to solve the technical problem that existing colonic drip devices, due to the lack of graded settings, make it difficult to quickly and accurately adjust the drip rate, thus resulting in unstable drip effects.

[0006] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0007] An adjustable drip rate colonic drip device includes a medicine bag, an outlet of which is connected to an outlet tube, a flow rate regulator is connected to the lower end of the outlet tube, and an injection tube is connected to the lower end of the flow rate regulator. The lower end of the injection tube is used for insertion into the colon.

[0008] The flow rate regulator includes a valve body with an inlet and an outlet. The inlet is connected to the outlet pipe and the outlet is connected to the injection pipe. A disc valve core is provided in the valve body. A knob is rotatably provided on the valve body. The shaft end of the knob is rotatably sealed and inserted into the valve body and connected to the disc valve core to adjust the disc valve core by rotation.

[0009] The disc valve core has a cavity, and multiple throttling orifices are symmetrically arranged on the outer side of the disc valve core. The multiple throttling orifices pass through and connect the cavity, and the flow areas of the multiple throttling orifices are different. When the knob is turned, the disc valve core can switch two symmetrical throttling orifices to connect the inlet and the outlet, so as to adjust the drip flow rate in multiple levels.

[0010] As a preferred embodiment of this utility model, the surface of the knob is symmetrically provided with multiple scale lines, each scale line corresponding to one of the multiple throttling orifices, and a pointer is formed protruding from the surface of the valve body.

[0011] Wherein, after the pointer is aligned with the scale line, the throttling orifice connects the inlet and the outlet through the cavity.

[0012] As a preferred embodiment of the present invention, a plurality of first grooves are symmetrically arranged on the surface of the valve body, and a plurality of spring pieces are symmetrically arranged on the side of the knob near the valve body. The plurality of spring pieces and the plurality of first grooves correspond one-to-one with the plurality of scale lines.

[0013] Wherein, after the multiple spring pieces are placed in the multiple first grooves, the two symmetrical throttling orifices are respectively aligned with the liquid inlet and the liquid outlet.

[0014] As a preferred embodiment of the present invention, a plurality of second grooves are symmetrically arranged on the surface of the valve body, and each second groove is located between two adjacent first grooves;

[0015] Wherein, after the plurality of the spring pieces are placed in the plurality of the second grooves, the liquid inlet and the liquid outlet are blocked by the side wall of the disc valve core.

[0016] As a preferred embodiment of this utility model, a plurality of drip holes are provided on the side wall of the injection tube away from the flow rate regulator.

[0017] As a preferred embodiment of this utility model, a sealing clip is provided at the liquid inlet at the upper end of the medicine bag, and an air pipe is connected to the upper end of the liquid outlet pipe, with the upper end of the air pipe being higher than the liquid inlet at the upper end of the medicine bag.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] This invention employs a multi-level adjustment method. A flow rate regulator is installed between the outlet pipe and the injection pipe. The flow rate regulator uses a disc valve core with multiple throttling orifices.

This allows for quick and accurate adjustment of the drip rate according to requirements, improving the dripping effect. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, this utility model provides an adjustable drip rate colonic drip device, including a medicine bag 1, an outlet pipe 2 connected to the outlet of the medicine bag 1, a flow rate regulator 3 connected to the lower end of the outlet pipe 2, an injection pipe 4 connected to the lower end of the flow rate regulator 3, and the lower end of the injection pipe 4 is used to insert into the colon.

[0031] The flow rate regulator 3 includes a valve body 31, which has an inlet 311 and an outlet 312. The inlet 311 is connected to the outlet pipe 2, and the outlet 312 is connected to the injection pipe 4. A disc valve core 32 is provided inside the valve body 31. A knob 33 is rotatably provided on the valve body 31. The shaft end of the knob 33 is rotatably sealed and inserted into the valve body 31 and connected to the disc valve core 32 to adjust the disc valve core 32 by rotation.

[0032] The disc valve core 32 has a cavity 321 inside. Multiple throttling orifices 322 are symmetrically arranged on the outer side of the disc valve core 32. The multiple throttling orifices 322 pass through and connect the cavity 321, and the flow area of ​​the multiple throttling orifices 322 is different. When the knob 33 is turned, the disc valve core 32 can switch the two symmetrical throttling orifices 322 to connect the inlet 311 and the outlet 312, so as to adjust the drip flow rate in multiple levels.

[0033] The colonic drip device of this embodiment mainly uses a flow rate regulator 3 to control the flow rate between the outlet tube 2 and the injection tube 4. The flow rate regulator 3 consists of a valve body 31 and a disc valve core 32. The knob 33 located outside the valve body 31 can control the rotation of the disc valve core 32, thereby changing the throttling orifice 322 of different specifications to align and connect the inlet 311 and the outlet 312. The inlet 311 and the outlet 312 are connected through two throttling orifices 322 of the same specifications and the cavity 321 to realize the adjustment of different flow rates, so that the injection tube 4 drips at different drip rates. The adjustment speed is fast, and the flow rate adjustment is accurate and stable.

[0034] Specifically, such as Figure 2As shown, when the two a-throttling orifices 322 are connected to the inlet 311 and the outlet 312 respectively, the inlet 311 and the outlet 312 are connected through the two a-throttling orifices 322 and the cavity 321, thereby allowing the liquid to flow. Since the flow cross sections of the a, b, c, and d-throttling orifices 322 are different, their resistances are different, resulting in different flow velocities, thus achieving the function of switching the throttling orifices 322 to adjust the flow rate.

[0035] In this design and manufacturing process, the flow rate of each type of orifice 322 is tested to determine its accuracy. This testing also determines the drip rate of the injection tube 4 after using each type of orifice 322, thus fixing the drip rate corresponding to each type of orifice 322 and achieving accurate adjustment and adaptation. This method of verifying the design through multiple tests is a standard technical approach in product design and will not be elaborated further.

[0036] Compared to existing drip devices that use pressure tubes to control the drip rate, the colonic drip device of this embodiment can utilize the pre-configured disc valve core 32's throttling orifice 322 to connect the inlet 311 and outlet 312, allowing the medication in the medication bag 1 to enter the injection tube 4 for dripping along the outlet tube 2, inlet 311, disc valve core 32, and outlet 312. The throttling orifice 322 of the disc valve core 32 has different specifications, thereby realizing multi-level flow rate adjustment to quickly and accurately adjust the drip flow rate according to different patients.

[0037] Specifically, before preparing the medication, depending on the patient's condition, the disc valve core 32 can be directly rotated to connect the matching throttling orifice 322 to the inlet 311 and outlet 312. Then, the disc valve core 32 can be rotated by half a unit angle to disconnect the throttling orifice 322 from the inlet 311 and outlet 312, thereby closing the flow rate regulator 3 and facilitating medication preparation. Before infusion, the disc valve core 32 can be directly rotated back by half a unit to connect the throttling orifice 322 to the inlet 311 and outlet 312, and infusion can be performed at this drip rate.

[0038] To ensure that operators can more accurately adjust the drip rate to the required level during use, the following preferred embodiments are provided.

[0039] like Figure 1 , Figure 3 As shown, the surface of the knob 33 is symmetrically provided with multiple scale lines 331, each scale line 331 corresponding to a multiple throttling orifice 322, and a pointer 313 protrudes from the surface of the valve body 31.

[0040] When the pointer 313 is aligned with the scale line 331, the throttling orifice 322 connects the inlet 311 and the outlet 312 through the cavity 321.

[0041] Specifically, a scale line 331 is set on the knob 33, which has a matching drip rate mark, such as 20 drops / min. A pointer 313 is provided on the valve body 31. When the scale line 331 is aligned with the pointer 313, it indicates that the throttle orifice 322, which marks this drip rate, is connected to the inlet 311 and the outlet 312, so that the medicine flows out from the injection tube 4 at this drip rate.

[0042] Of course, during the rotation of the disc valve core 32, over-rotation or under-rotation can easily occur, causing the throttling orifice 322 to misalign with the inlet 311 and outlet 312, resulting in inaccurate drip rate control. Based on this, the following preferred embodiments are provided.

[0043] like Figure 4 As shown, a plurality of first grooves 314 are symmetrically arranged on the surface of the valve body 31, and a plurality of spring pieces 332 are symmetrically arranged on the side of the knob 33 near the valve body 31. The plurality of spring pieces 332 and the plurality of first grooves 314 correspond one-to-one with the plurality of scale lines 331.

[0044] In this process, after multiple spring pieces 332 are placed in multiple first grooves 314, two symmetrical throttling holes 322 are aligned with the liquid inlet 311 and the liquid outlet 312, respectively.

[0045] Specifically, as the knob 33 rotates the disc valve core 32, the spring 332 rotates accordingly. When the scale line 331 aligns with the pointer 313, the spring 332 engages in the first groove 314. At this time, the spring 332 makes a "click" sound, and the spring 332 is blocked by the first groove 314, increasing the rotational resistance of the knob 33. This allows the scale line 331 to be precisely aligned with the pointer 313, avoiding over-rotation or under-rotation. It also ensures that the throttle orifice 322 is precisely aligned with the inlet 311 and the outlet 312, thus avoiding adjustment errors.

[0046] Of course, after any throttling orifice 322 is aligned with the inlet 311 and outlet 312, it is also necessary to quickly rotate the disc valve core 32 to close the flow rate regulator 3 at any time, so as to stop the dripping or perform intermediate operation in a timely manner. Based on this, the following preferred embodiments are provided.

[0047] like Figure 4 As shown, a plurality of second grooves 315 are symmetrically arranged on the surface of the valve body 31, and each second groove 315 is located between two adjacent first grooves 314;

[0048] In this process, after multiple spring pieces 332 are placed in multiple second grooves 315, the liquid inlet 311 and the liquid outlet 312 are blocked by the side wall of the disc valve core 32.

[0049] Specifically, the second groove 315 is located between the first groove 314. When the spring piece 332 rotates into the second groove 315, the part of the disc valve core 32 located between the two throttling holes 322 can be aligned with the liquid inlet 311 and the liquid outlet 312, thereby accurately sealing the liquid inlet 311 and the liquid outlet 312 and avoiding the situation of untimely or incomplete closure.

[0050] Of course, in order to ensure that the medicine is dripped evenly from the injection tube 4, such as Figure 1 As shown, multiple drip holes 41 are provided on the side wall of the injection tube 4 away from the flow rate regulator 3. The drug solution can overflow into the colon through the multiple drip holes 41, making the drug solution distribution more uniform.

[0051] During the dripping process, in order to ensure that the medicine in the medicine bag 1 is not contaminated and to maintain the pressure balance inside the medicine bag 1 so that the medicine flows out at an approximately uniform speed, the following preferred embodiments are provided.

[0052] like Figure 1 As shown, a sealing clip 11 is provided at the liquid inlet at the upper end of the medicine bag 1, and an air pipe 21 is connected to the upper end of the liquid outlet pipe 2. The upper end of the air pipe 21 is higher than the liquid inlet at the upper end of the medicine bag 1.

[0053] Specifically, the sealing clip 11 can block the inlet at the top of the medicine bag 1 to prevent the medicine in the medicine bag 1 from being contaminated during long-term dripping, while the trachea 21 can balance the pressure inside the medicine bag 1 (infusion principle of infusion set) so that the medicine in the medicine bag 1 can drip at a uniform speed.

[0054] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
