Description

Technical Field

[0001] This utility model relates to the field of connecting tube support technology, and in particular to a medical three-way fixation bracket. Background Technology

[0002] During clinical intravenous infusion, medication needs to be added temporarily according to changes in the patient's condition. A medical three-way valve is typically used as the connection tool, mainly consisting of three ports: A, B, and C. Ports A and C are used for the infusion, while port B can be connected to a syringe. Turning the valve on port B opens the infusion port for rapid medication administration.

[0003] In practice, because medical three-way valves lack a fixed connection, the connection at the three-way valve port is prone to loosening, leading to leakage of the medication. Subsequently, a Chinese utility model patent, such as the one with authorization announcement number CN219662645U and authorization announcement date of September 12, 2023, disclosed a medical three-way valve fixator, specifically including a three-way valve body, a buckle mechanism, and a fixing mechanism. The three-way valve body and the fixing mechanism are fixedly connected by the buckle mechanism. The fixing mechanism includes a base plate with two slots on its surface and straps on both sides of the base plate. One end of each strap is fixedly connected to the other by Velcro. Each of the two slot input ends has a support plate, which is rotatably connected to one end of the base plate. A clamping block is provided on the middle surface of the support plate. The buckle mechanism includes a fixed clamping plate, a movable clamping plate, an adjusting rod, and a fixing seat. A spring connects the movable clamping plate and the fixed seat.

[0004] Existing medical three-way stopcocks are designed with a snap-fit ​​mechanism and a fixation mechanism. The three-way stopcock body is fixed to the base plate through a snap-fit ​​mechanism consisting of a movable clamp, an adjusting rod, and a spring. However, the fixation method of the snap-fit ​​mechanism is complex. When at least two medical three-way stopcocks are connected in series for drug administration, it cannot be guaranteed that each medical three-way stopcock is reliably fixed, making it unsuitable for situations where multiple medical three-way stopcocks are connected in series. Utility Model Content

[0005] The technical problem this invention aims to solve is that the existing medical three-way fixation device has a complex fastening mechanism. When at least two medical three-way devices are connected in series for drug administration, it cannot be guaranteed that each medical three-way device is reliably fixed, and it is not suitable for situations where multiple medical three-way devices are connected in series for fixation.

[0006] To solve the above-mentioned technical problems, this utility model provides a medical three-way fixation bracket:

[0007] The medical three-way fixation frame includes a base and at least two snap-fit ​​structures disposed on the base, wherein the at least two snap-fit ​​structures are spaced apart along a straight line on the surface of the base;

[0008] At least two of the aforementioned snap-fit ​​structures are identical in structure. Each snap-fit ​​structure includes a concave block, a first sidewall, and a second sidewall. Both the first sidewall and the second sidewall are fixedly connected to the upper side of the concave block, and the first sidewall and the second sidewall are distributed at right angles.

[0009] The concave block has a positioning groove in the middle, which is used to limit the bottom of the tee body. A first snap-fit ​​is provided on the first side wall, which is used to engage with the side end of the tee body.

[0010] A second latch is provided on the second side wall. The second latch is used to limit the infusion interface end of the three-way body, and at least two of the second latches of the latch structure are distributed at intervals along the same straight line direction.

[0011] Furthermore, the first bayonet is a U-shaped bayonet, which includes an upper opening and a lower arc opening. The opening direction of the upper opening is perpendicular to the upper surface of the base, and the upper opening is connected to the lower arc opening.

[0012] Furthermore, the width of the upper opening is smaller than the width of the lower arc-shaped opening, and the upper opening is used for interference fit with the side end of the tee body.

[0013] Furthermore, the second latch is an arc-shaped latch, and the edge of the second latch away from the concave block is used to stop and cooperate with the infusion interface end of the three-way body.

[0014] Furthermore, the center-to-center distance between the positioning slots of two adjacent snap-fit ​​structures is equal to the length of a single tee body.

[0015] Furthermore, the upper edge of the second sidewall is located below the upper opening of the first bayonet.

[0016] Furthermore, the positioning groove is a circular groove, which is used to mate with the bottom contour of the tee body.

[0017] Furthermore, the base includes a fixing plate, a first rib, and a second rib. The fixing plate is in the shape of a rounded rectangle. The first rib and the second rib are both vertically connected to the lower side of the fixing plate. The first rib extends along the length direction of the fixing plate, and the second rib extends along the width direction of the fixing plate.

[0018] Compared with the prior art, the advantages of this medical three-way fixation frame are as follows: the medical three-way fixation frame adopts a base and at least two buckle structures. The at least two buckle structures are distributed at intervals along a straight line on the surface of the base. The buckle structure includes a concave block and a first side wall and a second side wall fixedly connected to the concave block. The first side wall and the second side wall are distributed at right angles.

[0019] Furthermore, a positioning groove is provided in the middle of the concave block, which limits the bottom of the three-way body. A first latch is provided on the first side wall, which clamps and fixes the side end of the three-way body. A second latch is provided on the second side wall, which limits the infusion interface end of the three-way body.

[0020] When in use, place the T-shaped body on the concave block of the snap-fit ​​structure, and simply press the T-shaped body firmly so that its side end is snapped into the first snap-fit. The positioning groove of the concave block, the first snap-fit ​​on the first side wall, and the second snap-fit ​​on the second side wall create a reliable spatial constraint effect on the T-shaped body.

[0021] In addition, at least two snap-fit ​​structures are spaced apart along a straight line on the surface of the base, and the second snaps of the at least two snap-fit ​​structures are spaced apart along the same straight line, ensuring that at least two connected three-way valve bodies can be accurately secured. This medical three-way valve fixation bracket has a simple fixing method, ensuring that each medical three-way valve is reliably fixed when at least two medical three-way valves are connected in series for drug administration, making it more suitable for situations where multiple medical three-way valves are connected in series.

[0032] like Figures 1 to 5As shown, a medical three-way fixation frame according to an embodiment of the present invention includes a base 1 and at least two snap-fit ​​structures 2 disposed on the base 1. The at least two snap-fit ​​structures 2 are spaced apart along a straight line on the surface of the base 1. The at least two snap-fit ​​structures 2 have the same structure. Each snap-fit ​​structure 2 includes a concave block 20, a first sidewall 21 and a second sidewall 22. The first sidewall 21 and the second sidewall 22 are both fixedly connected to the upper side of the concave block 20. The first sidewall 21 and the second sidewall 22 are distributed at right angles.

[0033] The concave block 20 has a positioning groove 200 in the middle, which is used to limit the bottom of the three-way body 3. A first latch 210 is provided on the first side wall 21, which is used to engage with the side opening end 31 of the three-way body 3. A second latch 220 is provided on the second side wall 22, which is used to limit the infusion interface end 32 of the three-way body 3. The second latches 220 of at least two latch structures 2 are distributed at intervals along the same straight line direction.

[0034] This medical three-way valve fixation frame adopts a design of base 1 and at least two snap-fit ​​structures 2. The at least two snap-fit ​​structures 2 are spaced apart along a straight line on the surface of the base 1. Each snap-fit ​​structure 2 includes a concave block 20 and a first sidewall 21 and a second sidewall 22 fixedly connected to the concave block 20. The first sidewall 21 and the second sidewall 22 are arranged at right angles. Furthermore, a positioning groove 200 is provided in the middle of the concave block 20, which limits the bottom of the three-way valve body 3. A first latch 210 is provided on the first sidewall 21, which secures the side opening 31 of the three-way valve body 3. A second latch 220 is provided on the second sidewall 22, which limits the infusion interface 32 of the three-way valve body 3.

[0035] In use, the three-way connector 3 is placed on the concave block 20 of the snap-fit ​​structure 2. Simply press the three-way connector 3 firmly so that its side opening 31 engages with the first snap-fit ​​210. The positioning groove 200 of the concave block 20, the first snap-fit ​​210 of the first sidewall 21, and the second snap-fit ​​220 of the second sidewall 22 reliably confine the three-way connector 3. Furthermore, at least two snap-fit ​​structures 2 are spaced apart along a straight line on the surface of the base 1, and the second snap-fit ​​220s of at least two snap-fit ​​structures 2 are spaced apart along the same straight line, ensuring that at least two connected three-way connectors 3 are accurately confined. This medical three-way connector fixation method is simple, and when at least two medical three-way connectors are connected in series for drug administration, it ensures that each medical three-way connector is reliably fixed, making it more suitable for situations where multiple medical three-way connectors are connected in series.

[0036] In this embodiment, the first bayonet 210 is a U-shaped bayonet, which includes an upper opening 211 and a lower arc-shaped opening 212. The opening direction of the upper opening 211 is perpendicular to the upper surface of the base 1, and the upper opening 211 is connected to the lower arc-shaped opening 212. The width of the upper opening 211 is smaller than the width of the lower arc-shaped opening 212. The upper opening 211 is used for an interference fit with the side end 31 of the tee body 3. During fixing, first align the side end 31 of the tee body 3 with the first bayonet 210, and press it firmly so that the side end 31 of the tee body 3 gradually enters the upper opening 211. When the side end 31 reaches the lower arc-shaped opening 212, the tee body 3 is snapped into place. The snap-fit ​​is reliable and not easy to fall off. The side end 31 is used to connect the syringe 4.

[0037] It should be noted that the second latch 220 is an arc-shaped latch. The edge of the second latch 220 away from the concave block 20 is used to stop and engage with the infusion interface end 32 of the three-way body 3, effectively limiting the relative position of the three-way body 3 in the infusion interface direction. Furthermore, the center-to-center distance between the positioning grooves 200 of two adjacent latching structures 2 is equal to the length of a single three-way body 3, ensuring that at least two series-connected three-way bodies 3 can be accurately constrained by different latching structures 2, preventing accidental detachment of the series-connected three-way bodies 3.

[0038] In this embodiment, the upper edge of the second sidewall 22 is located below the upper opening 211 of the first bayonet 210, avoiding the impact of excessive height of the second sidewall 22 on the quick assembly and disassembly of the tee body 3, thus facilitating the installation and disassembly of the tee body 3. Specifically, the positioning groove 200 is a circular groove, which is used to mate with the bottom contour of the tee body 3.

[0039] In addition, the base 1 includes a fixing plate 10, a first rib 11, and a second rib 12. The fixing plate 10 is a rounded rectangle. The first rib 11 and the second rib 12 are both vertically connected to the lower side of the fixing plate 10. The first rib 11 extends along the length of the fixing plate 10, and the second rib 12 extends along the width of the fixing plate 10. The base 1 can be used with a U-shaped clamp to clamp and fix the base 1 to the hospital bed, ensuring that the medical three-way fixation frame can be flexibly fixed in the corresponding position.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
