Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an infusion set regulator. Background Art

[0002] Among existing medical devices, an infusion set is a common medical device used to control the infusion speed and amount of a drug. An infusion set is usually equipped with a regulator to adjust the infusion speed of the drug. The regulator generally includes an adjustment wheel, and by rotating the adjustment wheel, the opening of the flow control valve of the infusion set can be changed, thereby adjusting the infusion speed.

[0003] However, there is a common problem with existing infusion regulators, that is, the regulating wheel is easy to loosen during use. A loose regulating wheel may lead to unstable infusion speed, and in some cases, the regulating wheel may fall off completely, resulting in the inability to properly infuse the drug, posing serious health risks to patients. In addition, a loose regulating wheel may also cause damage to the regulator, increasing the maintenance cost of medical equipment.

[0004] For example, the patent specification of the existing Chinese patent (publication number: CN214911811U) discloses a flow regulator for an infusion set and an infusion set using the flow regulator, including a housing and a roller. The housing has a bottom wall and a side wall, the bottom wall has a contact surface that contacts the infusion tube of the infusion set, and the side wall is provided with a connecting groove, which is in the shape of a strip or a circular hole.

[0005] However, in the implementation of relevant technologies, it was found that the above-designed flow regulator for an infusion pump and the infusion pump using the flow regulator had the following problems: although the device can adjust the flow of the infusion pump during use, the roller thereon is prone to loosening or even falling off during actual use, resulting in the inability to properly infuse the drug, posing serious health risks to patients.

[0006] In view of this, an infusion set regulator is provided to overcome the above-mentioned defects. Utility Model Content

[0007] The utility model aims to solve the shortcomings in the prior art and provides an infusion set regulator.

[0008] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an infusion set regulator, comprising an installation box, a mobile bin is provided in the installation box, a rotatable bidirectional screw is installed in the installation box, a first moving block and a second moving piece are threadedly connected on the outer wall of the bidirectional screw, a first clamp is installed above the first moving block, and a second clamp is installed above the second moving piece, a threaded butt sleeve is threadedly connected on the outer wall of the bidirectional screw outside the mobile bin, and a resistance spring is arranged between the threaded butt sleeve and the installation box.

[0009] As a further description of the above technical solution: the bottom surface of the installation box is set in an arc surface, and straps are fixedly installed on both sides of the installation box. The top surface of one side of the strap is fixedly provided with a Velcro fur surface, and the bottom surface of the other side of the strap is fixedly provided with a Velcro hook surface.

By providing a rotatable resistance piece connected to one side of the threaded butt sleeve, and providing a resistance spring fixedly connected between the resistance piece and the outer wall of the mounting box, the threaded butt sleeve will not drive the resistance spring to rotate during rotation, so that the resistance spring can be used continuously.

[0011] As a further description of the above technical solution: a guide rod is fixedly installed on the inner wall of the mobile warehouse, and the second moving piece and the first moving block are slidably mounted on the outer wall of the guide rod at the same time. By arranging the second moving piece and the first moving block to be slidably mounted on the outer wall of the guide rod at the same time, the movement of the first moving block and the second moving piece is limited by the guide rod, and derailment will not easily occur.

[0012] As a further description of the above technical solution: one end of the bidirectional screw rod is fixedly connected to a turning handle, an arc groove is opened on the outer wall of the turning handle, and the other end of the bidirectional screw rod is fixedly installed with a limiting block. By setting the turning handle and opening an arc groove on the outer wall of the turning handle, the user can easily rotate the bidirectional screw rod, and by setting the other end of the bidirectional screw rod to be fixedly installed with a limiting block, the threaded butt sleeve cannot be separated from the outer wall of the second movable piece.

[0013] As a further description of the above technical solution: a second support block is fixedly installed on one side of the second clamp, the number of the first clamps is two, and a first support block is fixedly connected to one side of the first clamp, and by setting the second support block and the first support block, the device will not easily fall into the mobile warehouse when the infusion line is placed.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model designs an infusion regulator, which is threadedly connected to a threaded butt sleeve on the outer wall of a bidirectional screw, and a rotatable resistance piece is connected to one side of the threaded butt sleeve, and finally a resistance spring is connected between the other side of the resistance piece and the outer wall of a mounting box, so that the bidirectional screw cannot be easily rotated by rotating the threaded butt sleeve, so that the first clamping piece and the second clamping piece will not be easily loosened for the infusion pipe, and the flow rate control can be more stable.

[0016] 2. The utility model designs an infusion regulator, which has two straps and respectively installs a Velcro fleece surface and a Velcro hook surface on the two straps, so that the infusion tube will not be easily interfered with by other objects, making the patient's infusion environment safer and the device can be recycled, saving medical resources.

A resistance spring 15 is fixedly connected between the resistance piece 18 and the outer wall of the installation box 1. By providing a rotatable resistance piece 18 connected to one side of the threaded docking sleeve 17, and providing a resistance spring 15 fixedly connected between the resistance piece 18 and the outer wall of the installation box 1, the threaded docking sleeve 17 will not drive the resistance spring 15 to rotate during the rotation process, so that the resistance spring 15 can be used continuously, and the mobile bin 2 can be moved. A guide rod 13 is fixedly installed on the inner wall of the movable bin 2, and the second movable piece 6 and the first movable block 4 are slidably mounted on the outer wall of the guide rod 13 at the same time. By arranging that the second movable piece 6 and the first movable block 4 are slidably mounted on the outer wall of the guide rod 13 at the same time, the movement of the first movable block 4 and the second movable piece 6 is limited by the guide rod 13, and derailment will not occur easily. One end of the bidirectional screw rod 3 is fixedly connected to a rotating handle 14, and an arc groove is opened on the outer wall of the rotating handle 14. A limiting block 16 is fixedly installed on the other end of the bidirectional screw rod 3. By setting a turning handle 14 and opening an arc groove on the outer wall of the turning handle 14, the user can easily rotate the bidirectional screw rod 3, and by setting a limit block 16 fixedly installed on the other end of the bidirectional screw rod 3, the threaded butt sleeve 17 cannot be separated from the outer wall of the second movable piece 6, and a second support block 9 is fixedly installed on one side of the second clamping piece 7.
