Description

Technical Field

[0001] This utility model relates to the field of infusion technology, specifically to an adjustable infusion regulator. Background Technology

[0002] Existing infusion regulators have several problems in use. Due to the lack of a locking mechanism, the adjusting roller is prone to slippage, and patients or their families may accidentally rotate it, causing the infusion flow rate to increase or decrease, which can have adverse effects on the patient. Furthermore, the infusion tubing may bend during use, leading to infusion termination and affecting treatment efficacy.

[0003] Regarding the issue of infusion regulators lacking a locking mechanism, leading to easy slippage of the adjusting roller and accidental rotation by patients causing changes in flow rate, several invention patents have been developed. For example:

[0004] CN108355199A discloses a lockable infusion flow regulator, including a frame, an adjusting pressure roller, a locking half-roller, and a locking structure. This patent achieves a locking function by setting up a locking half-roller and a locking structure, but it still suffers from insufficient stability in the connection between the locking half-roller and the adjusting pressure roller, making it prone to accidental unlocking.

[0005] CN105641779A discloses an infusion flow rate regulator that guides fluid through a fixed base or a fixed base and an adjusting rod. The cross-sectional area of ​​the fluid flow channel used for infusion at the speed adjustment position is adjusted by moving the adjusting rod along its channel, thereby changing the infusion flow rate in the infusion device. While this patent allows for more precise flow rate control, it still suffers from a complex adjustment process requiring two-handed operation. Utility Model Content

[0006] In view of the problems in the existing technology where the regulator lacks a locking structure, protective cover and anti-folding ring, which leads to the adjustment roller being easy to slip, being misoperated and the infusion tube being bent, the present invention provides an adjustable infusion regulator to solve the above problems.

[0007] The technical solution adopted by this utility model is as follows: an adjustable infusion regulator, including an adjusting shell, an infusion channel inside the adjusting shell, an adjusting groove communicating with the infusion channel on the upper outer side of the adjusting shell, an adjusting roller that can roll along the adjusting groove in the adjusting groove, a sliding part on the end face of the adjusting roller, the sliding part being movably engaged with strip-shaped sliding grooves on both sides of the adjusting groove, one end of the sliding groove being inclined toward the infusion channel, and a locking knob located on the outer side of the adjusting shell being screwed onto one of the sliding parts; a protective cover arranged along the length of the adjusting shell is hinged to one end of the adjusting groove on the adjusting shell, and a torsion spring is fitted at the hinge position of the protective cover, so that the protective cover closes the adjusting groove under the torsion of the torsion spring.

[0008] In this technical solution, the infusion regulator is used by passing the infusion tubing through the infusion channel.

Simultaneously, a protective cover is hinged to one end of the adjusting housing corresponding to the adjusting slot. Under the action of a torsion spring, the protective cover automatically closes the adjusting slot, covering the adjusting roller and preventing accidental operation. This improves the safety and stability of the infusion regulator and avoids adverse effects caused by misoperation.

[0009] Preferably, the lower end of the adjusting housing is provided with an installation slot arranged along the infusion channel, so that the infusion tube can be inserted into the infusion channel through the installation slot.

[0010] Preferably, the mounting bayonet opening has multiple pairs of symmetrically arranged anti-detachment protrusions on both sides.

[0011] Preferably, the adjusting roller has anti-slip texture on its outer periphery.

[0012] Preferably, the locking knob has an anti-slip layer on the end face near the adjusting housing.

[0013] Preferably, the protective cover has anti-slip protrusions on the side away from the hinge position.

[0014] Preferably, the protective cover is transparent.

[0015] The beneficial effects of this utility model are as follows: By setting a locking knob, the adjusting roller can be locked after adjustment, preventing accidental operation that could cause the infusion flow rate to increase or decrease, thus improving the safety of the infusion regulator; the protective cover automatically closes after adjustment, covering the adjusting roller and preventing accidental operation, further enhancing the safety of the infusion regulator; and the anti-bend ring, with its spiral structure and elasticity, prevents the infusion tubing from bending and causing infusion termination, ensuring the continuity and stability of the infusion, thus possessing high practical value.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figure 1 and Figure 2 As shown in the figure, a specific embodiment of this utility model provides an adjustable infusion regulator for infusion use, which is convenient to adjust and avoids misoperation. It includes an adjusting housing 100, an infusion channel within the adjusting housing 100, and an adjusting groove 110 communicating with the infusion channel on the upper outer side of the adjusting housing 100. An adjusting roller 200 capable of rolling along the adjusting groove 110 is provided within the adjusting groove 110. A sliding part is provided on the end face of the adjusting roller 200, which movably engages with strip-shaped sliding grooves 120 located on both sides of the adjusting groove 110. One end of the sliding groove 120 is inclined towards the infusion channel. A locking knob 300 located on the outer side of the adjusting housing 100 is screwed onto one of the sliding parts. A protective cover 400, arranged along the length of the adjusting housing, is hinged to one end of the adjusting groove 110. A torsion spring is fitted at the hinge position of the protective cover 400, so that the protective cover 400 closes the adjusting groove 110 under the torsion of the torsion spring.

[0023] like Figure 1 and Figure 2 As shown, with the above settings, the infusion regulator is used by installing the infusion tubing in the infusion channel and adjusting the speed by rotating the adjusting roller 200. Because the slide 120 has an inclined structure, different positions of the adjusting roller 200 in the slide 120 can achieve different degrees of pressure. After adjustment, the position of the adjusting roller 200 can be locked by the locking knob 300 to prevent accidental operation. Simultaneously, a protective cover 400 is hinged to one end of the adjusting housing 100 corresponding to the adjusting groove 110. Under the action of a torsion spring, the protective cover 400 can automatically close the adjusting groove 110, covering the adjusting roller 200 and preventing accidental operation. This improves the safety and stability of the infusion regulator and avoids adverse effects caused by misoperation.

[0024] like Figure 1 and Figure 2 As shown, to facilitate the installation of the regulator structure at the corresponding position of the infusion tube, the lower end of the regulating housing is provided with a mounting slot arranged along the infusion channel, allowing the infusion tube to be inserted into the infusion channel through the mounting slot. Multiple pairs of symmetrically arranged anti-dislodgement protrusions are provided on both sides of the mounting slot opening. In this way, the infusion tube can be quickly inserted into the infusion channel through the mounting slot, and the anti-dislodgement protrusion structure prevents it from falling off, improving the stability of the adjustment. In practical applications, the diameter of the infusion channel should be compatible with the diameter of the infusion tube, and the width of the mounting slot should be smaller than the diameter of the infusion tube.

[0025] like Figure 1 and Figure 2 As shown, to facilitate adjustment, the adjusting roller 200 has anti-slip texture on its outer periphery, and the protective cover 400 has anti-slip protrusions 410 on the side away from the hinge position, improving the operating feel and preventing slippage; the protective cover 400 is transparent, making it easy to observe the position of the adjusting roller 200 and facilitating operation and adjustment; in addition, the locking knob 300 has an anti-slip layer 310 on the end face near the adjusting housing, which increases the friction between the locking knob 300 and the adjusting housing 100, resulting in higher locking stability; the anti-slip layer 310 is made of rubber.

[0026] like Figure 2 As shown, the operating steps of this device are as follows: First, pass the infusion tubing through the anti-bend ring 500 and the infusion channel in sequence. Then, rotate the adjusting roller 200 to allow the sliding part to slide within the groove 120, thereby adjusting the infusion flow rate within the infusion tubing. Once the appropriate flow rate is achieved, rotate the locking knob 300 to screw it onto the sliding part, locking the adjusting roller 200 in its current position. The protective cover 400, under the action of a torsion spring, closes the adjusting groove 110, blocking the adjusting roller 200 and preventing accidental operation. When it is necessary to adjust the flow rate again, lift the protective cover 400 upwards and release the locking knob 300 to readjust. The spiral structure and elastic design of the anti-bend ring 500 prevent the infusion tubing from bending, ensuring the continuity and stability of the infusion.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
