Description

Technical Field

[0001] This utility model relates to the field of infusion set technology, and in particular to a pressure alarm drip rate regulator for an infusion set that prevents tube dislodgement. Background Technology

[0002] An infusion set is a sterile medical device used to establish a channel between a vein and a medication. It delivers drugs or fluids through gravity, pressure, or mechanical actuation. The infusion channel is established by puncturing a vein needle to deliver drugs, nutritional solutions, or electrolyte solutions. At the same time, the flow rate is controlled by a regulator to adapt to different drug properties and patient needs.

[0003] Traditional infusion sets typically involve directly piercing the stopper with a puncture device. When the tubing is impacted, the puncture device can easily slip out of the stopper, causing backflow of blood and posing a significant risk to the patient. Furthermore, traditional regulators often use rollers; when the regulator housing is subjected to tension, the rollers can roll relative to the tubing, causing adjustment failure. Therefore, a pressure alarm drip regulator for an anti-dislodgement infusion set is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressure alarm drip regulator for an anti-dislodgement infusion set, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a pressure alarm drip regulator for an anti-dislodgement infusion set, comprising an infusion set body with a snap-fit ​​assembly fastened to its top. A three-way tube and a regulator housing are respectively installed from top to bottom at the bottom of the infusion set body. A protective plug is fitted onto the middle port of the three-way tube, and a protective shell is installed in the middle of the three-way tube. A protective end cap is snapped onto the end of the three-way tube. An extension head that can connect with the three-way tube is provided on the side of the protective end cap away from the protective shell. A pressure sensor is installed in the middle of the extension head, and an electrical connector is installed at the other end of the extension head. A pusher is slidably installed on one side of the outer wall of the regulator housing, and multiple positioning grooves are formed on its side. A clamping member is rotatably installed inside the regulator housing, with the middle of the clamping member fitting against the end face of the pusher. A stop is installed at the bottom of the side of the regulator housing, with one end of the stop penetrating the regulator housing and entering the interior of a positioning groove.

[0006] Preferably, in any of the above embodiments, the snap-fit ​​assembly includes two integral snap-fit ​​semi-rings that can rotate at a certain angle. Each end of one integral snap-fit ​​semi-ring has two slots, and the end of the other integral snap-fit ​​semi-ring is equipped with a first buckle. The two first buckles engage with the two slots respectively. This design facilitates the integral design of the adjacent sides of the two integral snap-fit ​​semi-rings, and the design is thinned, which makes it convenient for the two integral snap-fit ​​semi-rings to rotate at a certain angle. When the first buckle engages with the slot, the two integral snap-fit ​​semi-rings can be fastened to the stopper of the external infusion bottle.

[0007] Preferably, in any of the above solutions, the bottom ends of both of the two interconnected snap-fit ​​semi-rings are fixedly connected with concave blocks. After the snap-fit ​​assembly is engaged, the two concave blocks surround the bottom end of the puncture device of the infusion set body. This solution facilitates the rotation of the two concave blocks after the two interconnected snap-fit ​​semi-rings are engaged, and they surround the root position of the puncture device of the infusion set body, thereby cooperating with the two interconnected snap-fit ​​semi-rings to achieve the purpose of preventing detachment.

[0008] Preferably, one end of the protective end cap is equipped with multiple second buckles that engage with the protective shell, and the edge of the other end of the protective end cap protrudes outward to form a protrusion. In this design, the protrusion provides a fulcrum for pulling out the protective end cap, facilitating the operator's initial installation and subsequent disassembly of the protective end cap. The inner wall of the protective shell is provided with a protruding ring, which facilitates engagement with the multiple second buckles to limit the position of the protective end cap. After the protective end cap engages with the protective shell, it facilitates the compression of the protective plug and isolates the middle part of the tee tube from the external environment, preventing bacterial contamination of the middle part of the tee tube.

[0009] Preferably, in any of the above solutions, a diaphragm is provided on the side of the expansion head near the inner wall of the three-way tube. In this solution, the diaphragm facilitates the division of the space inside the expansion head into two parts, and after the expansion head is connected to the middle of the three-way tube, the diaphragm can prevent the liquid medicine from coming into contact with the pressure sensor.

[0010] Preferably, in any of the above embodiments, the pushing member is inclined toward the pressing member, the top of the pushing member is T-shaped, and the bottom of the pushing member is provided with an inclined surface that fits against the pressing member. In this embodiment, the T-shaped structure at the top of the pushing member increases the contact area between the pushing member and the operator's fingers, making it easier for the operator to push the pushing member. The top of the pressing member is rotatably connected to the inside of the regulator housing through a connecting pin. The pressing member rotates under the pushing action of the pushing frame, thereby facilitating the compression and deformation of the tubing of the infusion set body, and adjusting the infusion drip rate. At the same time, the top of the baffle engages with the positioning groove, thereby stabilizing the position of the pushing frame and preventing it from being affected by external forces.

[0011] Preferably, in any of the above solutions, the baffle is T-shaped, with its middle part fixedly connected to the regulator housing. In this solution, the T-shaped structure of the baffle allows the operator to press the bottom of the baffle, causing the middle part of the baffle to rotate relative to the regulator housing, thereby causing the top of the baffle to slide outward and separate from the positioning groove. This allows the operator to slide the position of the pusher and adjust the infusion drip rate.

[0012] This utility model has the following advantages:

[0013] 1. This anti-dislodgement infusion set pressure alarm drip regulator, through the infusion set body, has a snap-fit ​​component installed at its top. When the first snap-fit ​​engages with the slot, the snap-fit ​​component is stably snapped into the external bottle stopper position. At the same time, the concave block clamps the infusion set body, thereby achieving the anti-dislodgement effect. By setting the regulator shell, pusher, and stop lever, pressing down the bottom of the stop lever separates its top from the positioning groove. Then, pressing the pusher causes the bottom of the pusher to push the clamping component to rotate, clamping the tubing part of the infusion set body to control the flow rate. Releasing the stop lever allows its top to enter the interior of the positioning groove, preventing the injection speed adjustment from being affected by external forces, thus effectively solving the problems existing in the prior art.

[0014] 2. This anti-dislodgement infusion set pressure alarm drip regulator features a three-way tube with an external protective shell. A protective end cap is attached to the end of the protective shell, and a second clip on the end of the protective end cap engages with the protective shell, facilitating the tightening of the protective plug to prevent bacteria from entering the three-way tube. After removing the protective end cap and plug, an extension head is connected to the middle of the three-way tube, allowing the infusion pressure to be directly transmitted to a pressure sensor. The pressure sensor is electrically connected to an external monitor to ensure infusion safety. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figures 1 to 6 As shown, an anti-dislodgement infusion set pressure alarm drip regulator includes an infusion set body 1, with a snap-fit ​​assembly 9 fastened to its top. A three-way tube 10 and a regulator housing 2 are respectively installed from top to bottom at the bottom of the infusion set body 1. A protective plug 15 is fitted onto the middle port of the three-way tube 10, and a protective shell 8 is installed in the middle of the three-way tube 10. A protective end cap 6 is snapped onto its end. An extension head 7, which can connect with the three-way tube 10, is provided on the side of the protective end cap 6 away from the protective shell 8. A pressure sensor 11 is installed in the middle of the extension head 7, and an electrical connector 13 is installed at the other end of the extension head 7. A pusher 5 is slidably installed on one side of the outer wall of the regulator housing 2, and multiple positioning grooves 16 are opened on its side. A clamping member 12 is rotatably installed inside the regulator housing 2, with the middle of the clamping member 12 fitting against the end face of the pusher 5. A stop 3 is installed at the bottom of the side of the regulator housing 2, with one end of the stop 3 penetrating the regulator housing 2 and entering the interior of a positioning groove 16.

[0024] The snap-fit ​​assembly 9 includes two integrated snap-fit ​​semi-rings 901 that can rotate at a certain angle. Each end of one integrated snap-fit ​​semi-ring 901 has two slots 902, and the end of the other integrated snap-fit ​​semi-ring 901 is equipped with a first buckle 903. The two first buckles 903 are respectively snapped into the two slots 902. As an optional technical solution of this utility model, this facilitates the integrated design of the adjacent sides of the two integrated snap-fit ​​semi-rings 901, and the design is thinned, which makes it convenient for the two integrated snap-fit ​​semi-rings 901 to rotate at a certain angle at this position. When the first buckle 903 is snapped into the slot 902, it is convenient for the two integrated snap-fit ​​semi-rings 901 to be fastened to the stopper of the external infusion bottle.

[0025] The bottom ends of the two connected snap-fit ​​semi-rings 901 are fixedly connected with concave blocks 904. After the snap-fit ​​components are engaged, the two concave blocks 904 surround the bottom end of the puncture device of the infusion set body 1. As an optional technical solution of this utility model, this makes it easy for the two concave blocks 904 to rotate after the two connected snap-fit ​​semi-rings 901 are engaged and surround the root position of the puncture device of the infusion set body 1, thereby cooperating with the two connected snap-fit ​​semi-rings 901 to achieve the purpose of preventing them from falling off.

[0026] One end of the protective end cap 6 is equipped with multiple second snap fasteners 14 that engage with the protective shell 8. The edge of the other end of the protective end cap 6 protrudes outward to form a protrusion. As an optional technical solution of this utility model, the protrusion provides a fulcrum for pulling out the protective end cap 6, making it convenient for operators to perform pre-installation and post-disassembly operations on the protective end cap 6. The inner wall of the protective shell 8 is provided with a protruding ring, which is convenient to engage with multiple second snap fasteners 14 to limit the position of the protective end cap 6. After the protective end cap 6 is engaged with the protective shell 8, it is convenient to press the protective plug 15, and at the same time isolate the middle part of the three-way pipe 10 from the external environment to prevent the middle part of the three-way pipe 10 from being infected by bacteria.

[0027] A diaphragm is provided on the side of the expansion head 7 near the inner wall of the three-way tube 10. As an optional technical solution of this utility model, the diaphragm facilitates the division of the internal space of the expansion head 7 into two parts, and after the expansion head 7 is connected to the middle of the three-way tube 10, the diaphragm can prevent the liquid medicine from contacting the pressure sensor 11.

[0028] The pusher 5 is tilted towards the clamping member 12. The top of the pusher 5 is T-shaped, and the bottom of the pusher 5 is provided with an inclined surface that fits against the clamping member 12. As an optional technical solution of this utility model, the T-shaped structure at the top of the pusher 15 increases the contact area between the pusher 15 and the operator's fingers, making it easier for the operator to push the pusher 15. The top of the clamping member 12 is rotatably connected to the inside of the regulator housing 2 through a connecting pin. The clamping member 12 rotates under the pushing action of the pusher 15, which facilitates the clamping of the tubing of the infusion set body 1 and causes it to deform, thereby adjusting the infusion drip rate. At the same time, the top of the baffle 3 is engaged with the positioning groove 16, thereby stabilizing the position of the pusher 15 and preventing it from being affected by external forces.

[0029] The baffle 3 is T-shaped, with its middle part fixedly connected to the regulator housing 2. As an optional technical solution of this utility model, the T-shaped structure of the baffle 3 allows the operator to press the bottom end of the baffle 3, causing the middle part of the baffle 3 to rotate relative to the regulator housing 2, thereby causing the top end of the baffle 3 to slide outward and separate from the positioning groove 16. This allows the operator to slide the position of the pusher 5 to adjust the infusion drip rate.

[0030] This type of anti-dislodgement infusion set pressure alarm drip regulator requires the following steps to use:

[0031] 1) When in use, pierce the bottle stopper with the puncture device of the infusion set body 1, and then fold the two connected snap-fit ​​half rings 901 on the snap-fit ​​assembly 9 so that the first snap 903 snaps into the slot 902.

[0032] 2) The concave block 904 is locked at the root of the puncture device in the body of the infusion set 1, thereby preventing the infusion set from falling off;

[0033] 3) Press down the bottom of the gear lever 3, and the top of the gear lever 3 will disengage from the inside of the positioning groove 16;

[0034] 4) Press the pusher 5 diagonally downwards. The bottom end of the pusher 5 slides relative to the clamping part 12. The clamping part 12 is pushed to clamp the tubing of the infusion set body 1 to achieve drip rate adjustment. Release the lever 3. The top of the baffle 3 engages with the positioning groove 16 at a certain position.

[0035] 5) When measuring the infusion pressure, the protective end cap 6 and the protective plug 15 are disassembled in sequence. Then, the expansion head 7 is connected to the middle of the three-way tube 10. The pressure of the drug solution is then transmitted to the diaphragm, which deforms, causing a change in the air pressure inside the expansion head 7. The pressure sensor 11 receives the pressure change and transmits a signal to the outside. At the same time, the pressure sensor 11 is electrically connected to the external monitor, so that the external monitor can analyze the signal and monitor the infusion pressure.

[0036] In summary, during use, the user utilizes the infusion set body 1, which has a locking component 9 installed at its top. When the first latch 903 engages with the slot 902, the locking component 9 is stably locked onto the external bottle stopper. Simultaneously, the concave block 904 clamps the infusion set body 1, thus preventing tube dislodgement. By configuring the regulator housing 2, the pusher 5, and the stop lever 3, pressing down the bottom of the stop lever 3 separates its top from the positioning groove 16. Then, pressing the pusher 5 causes its bottom to push the clamping member 12 to rotate, clamping the tubing portion of the infusion set body 1 to control the flow rate. Releasing the stop lever 3 allows its top to enter... The positioning groove 16 is designed to prevent injection speed adjustment from being affected by external forces, thus effectively solving the problems existing in the prior art. A three-way tube 10 is then installed with a protective shell 8 on the outside. A protective end cap 6 is snapped onto the end of the protective shell 8. After the second buckle 14 at the end of the protective end cap 6 is snapped onto the protective shell 8, it is easy to press the protective plug 15 to prevent bacteria from entering the interior of the three-way tube 10. After the protective end cap 6 and the protective plug 15 are removed, the expansion head 7 is connected to the middle of the three-way tube 10, which facilitates the direct transmission of infusion pressure to the pressure sensor 11. The pressure sensor 11 is electrically connected to an external monitor to ensure infusion safety.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
