Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary device technology, specifically a hand fixation device for intravenous infusion in psychiatric patients. Background Technology

[0002] Traditional intravenous infusion procedures are usually performed with the cooperation of ordinary patients, allowing medical staff to smoothly complete steps such as puncture, fixation, and drip rate adjustment. However, due to the special nature of their mental state, psychiatric patients often exhibit restlessness, non-cooperation, or even resistance to treatment. This makes intravenous puncture difficult, increasing the risk of puncture failure, vascular damage, and increased patient suffering. Current methods typically involve medical staff using straps or similar devices to fix the patient's arm or to a chair support to prevent arm movement, allowing for relatively stable puncture through the patient's hand. However, in practice, because the patient's hand is not fixed, the medical staff still need to use one hand to counteract the patient's hand movement, which significantly affects the puncture procedure. Therefore, we propose a hand fixation device for intravenous infusion in psychiatric patients. Summary of the Invention

[0003] To address the problems mentioned in the background section, this invention provides a hand fixation device for intravenous infusion in psychiatric patients, which solves the problem that non-cooperation by psychiatric patients during hand punctures can affect medical staff.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a hand fixation device for intravenous infusion in psychiatric patients, comprising an arm support assembly and a second arm support assembly, further comprising: a telescopic rod disposed at the bottom of the arm support assembly for adjusting the angle between the arm support assembly and the second arm support assembly; an elastic cable tie mounted on the arm support assembly; and a connecting component disposed at the bottom of the arm support assembly for controlling the connection between the telescopic rod and the elastic cable tie;

[0005] The arm support assembly includes a support plate 1, on which two sets of retaining rings are hinged. One end of each retaining ring is elastically connected to an elastic locking block, and one end of the elastic locking block can engage with the support plate 1.

[0006] The second pallet assembly includes a second pallet hinged to one end of the pallet, a support block fixedly connected to the second pallet, and a Velcro fastener provided on the support block;

[0007] The telescopic rod includes a piston rod hinged to the bottom of a support plate, and a sleeve hinged to the bottom of the support plate. One end of the sleeve extends into the piston rod and is movably connected to the piston rod. Hydraulic oil is stored inside the piston rod.

[0008] Adjusting the connecting component and rotating the second support plate allows the sleeve to inject the hydraulic oil inside the piston rod into the elastic cable tie through the connecting component.

[0009] Preferably, a crossbar is fixedly connected to one side of the support block, a baffle is fixedly connected to one end of the crossbar, and a connecting block is fixedly connected between the two retaining rings.

[0010] Preferably, one end of the piston rod has a channel one; the connecting component includes a connecting pipe fixed to the bottom of the support plate one, a column elastically connected inside the connecting pipe, one end of the column extending to the outside of the connecting pipe and splinedly connected to the connecting pipe, a channel three and a channel two are opened on the connecting pipe, a connecting piece is also fixedly connected to the connecting pipe, the channel one and the channel two are connected through the connecting piece, and a three-way opening is also opened on the column. In the initial state, the column is subjected to the tension of its tension spring portion, causing the three-way opening to be misaligned with the channel two and the channel three respectively, and the top end of the channel three is connected to the elastic cable tie;

[0011] The connecting component is filled with hydraulic oil and is a corrugated pipe or a hose.

[0012] Preferably, an elastic rod is hinged to one end of the column outside the connecting pipe, and a straight groove is opened on the elastic rod. A limiting post is fixed to the bottom of the second support plate, and the bottom of the limiting post is movably engaged inside the straight groove.

[0013] Preferably, the elastic cable tie has a fixedly connected channel four; the top of the channel three extends into the interior of the tray one and is connected to the elastic cable tie through the channel four.

[0014] Preferably, the elastic cable tie has two sealed ends and is divided into upper and lower parts, wherein the upper part of the elastic cable tie is installed on one of the retaining rings, and the lower part of the elastic cable tie is installed on the first tray. When the retaining ring is closed, the elastic cable tie can be made into a ring shape as a whole.

[0015] Preferably, the upper end of the elastic cable tie is inverted triangular, and the lower end of the elastic cable tie is inverted triangular groove and can engage with the upper end of the elastic cable tie.

[0016] Preferably, a cam is fixedly connected to one end of the piston rod; a pressure block that can move in the vertical direction is movably connected inside the first support plate, and an arc-shaped groove is opened in the middle of the pressure block; when the piston rod rotates around the axis, it can cause the cam to squeeze the arc-shaped groove upward.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] The above procedure involves medical staff placing the patient's arm on tray one, rotating the retaining ring to engage the elastic block with tray one to fix the patient's arm, and using Velcro to fix the patient's hand to the support block in a semi-clenched state, with the back of the hand exposed. Then, medical staff pull the column to connect channel one through the connector, channel two, three-way opening, channel three, and elastic cable tie. At this time, rotating tray two will cause the patient's wrist to rotate downwards. During the rotation of tray two, the sleeve discharges the hydraulic oil in the piston rod through channel one and the connecting component into the elastic cable tie. After closing the connecting component, the angle of tray two will be fixed, and the patient's arm and hand will form an angle, which can also prevent the patient's hand from shaking, thereby increasing the stability of the medical staff when puncturing the patient's hand.

[0019] The above scheme fixes the patient's arm to the support plate by closing the elastic block, so that the elastic band can be in a ring shape and wrapped around the patient's arm. At this time, hydraulic oil is injected into the elastic band through channel three and channel four, which will cause the elastic band to expand and squeeze the patient's arm, thus producing an effect similar to a tourniquet, and making the blood vessels in the patient's arm clearer, thereby facilitating the accuracy of puncture by medical staff.

[0020] The above solution works by rotating the hinge of the piston rod when the second support plate rotates, which in turn drives the cam to rotate and squeezes the bottom of the pressure block to force the pressure block to move upward. This increases the pressure between the first support plate and the arc groove on the patient's arm, preventing it from shaking during puncture and further increasing the stability of medical staff during the puncture process.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 10 As shown, the present invention provides a hand fixation device for intravenous infusion in psychiatric patients, including an arm support assembly 1 and an arm support assembly 2, and further including: a telescopic rod 3, which is disposed at the bottom of the arm support assembly 1 for adjusting the angle between the arm support assembly 1 and the arm support assembly 2; an elastic cable tie 5, which is installed on the arm support assembly 1; and a connecting component 4, which is disposed at the bottom of the arm support assembly 1 for controlling the connection between the telescopic rod 3 and the elastic cable tie 5;

[0034] The arm support assembly 1 includes a support plate 11, on which two sets of retaining rings 12 are hinged. One end of the retaining ring 12 is elastically connected to an elastic block 13, and one end of the elastic block 13 can engage with the support plate 11.

[0035] The second tray assembly 2 includes a second tray 21 hinged to the end of the first tray 11, a support block 22 fixedly connected to the second tray 21, and a Velcro 23 provided on the support block 22.

[0036] The telescopic rod 3 includes a piston rod 31 hinged to the bottom of the support plate 11, and a sleeve 32 hinged to the bottom of the support plate 21. One end of the sleeve 32 extends into the interior of the piston rod 31 and is movably connected to the piston rod 31. Hydraulic oil is stored inside the piston rod 31.

[0037] Adjusting the connecting component 4 and rotating the second tray 21 allows the sleeve 32 to inject the hydraulic oil inside the piston rod 31 into the elastic cable tie 5 through the connecting component 4; a channel 311 is provided at one end of the piston rod 31.

[0038] The connecting component 4 includes a connecting pipe 41 fixed to the bottom of the tray 11. A column 42 is elastically connected inside the connecting pipe 41. One end of the column 42 extends to the outside of the connecting pipe 41 and is splinedly connected to the connecting pipe 41. The connecting pipe 41 has a third channel 412 and a second channel 411. A connecting piece 44 is also fixed to the connecting pipe 41. The first channel 311 and the second channel 411 are connected through the connecting piece 44. The column 42 also has a three-way opening 43. In the initial state, the column 42 is subjected to the tension of its tension spring, causing the three-way opening 43 to be misaligned with the second channel 411 and the third channel 412 respectively. The top end of the third channel 412 is connected to the elastic cable tie 5.

[0039] The connecting part 44 is filled with hydraulic oil and is a bellows or hose, which ensures that when the telescopic rod 3 rotates relative to the support plate 11, the channel 2 411 and the channel 1 311 can be stably connected.

[0040] Using the above method, medical staff place the patient's arm on tray 11, rotate the retaining ring 12 to engage the elastic locking block 13 with tray 11 to fix the patient's arm, and use Velcro 23 to fix the patient's hand to the support block 22 and keep it in a semi-clenched state, with the back of the hand exposed. Then, medical staff pull the column 42 to connect channel 1 311 through connector 44, channel 2 411, three-way port 43, channel 3 412 and elastic cable tie 5. At this time, rotating tray 21 will cause the patient's wrist to rotate downward. During the rotation of tray 21, sleeve 32 discharges the hydraulic oil in piston rod 31 through channel 1 311 and connector 4 into elastic cable tie 5. Then close connector 4 to fix the angle of tray 21, and the patient's arm and hand will form an angle, which can also prevent the patient's hand from shaking, thereby increasing the stability of medical staff when puncturing the patient's hand.

[0041] like Figures 1 to 3 As shown, a crossbar 221 is fixedly connected to one side of the support block 22, a baffle 222 is fixedly connected to one end of the crossbar 221, and a connecting block 121 is fixedly connected between the two retaining rings 12.

[0042] By using the above scheme, the patient's thumb is placed below the horizontal bar 221 to limit the thumb in the vertical direction and to make the web of the patient's hand fit against the horizontal bar 221. At the same time, a baffle 222 is set to limit the thumb in the horizontal direction, which further prevents the patient's hand from shaking.

[0043] like Figures 3-8 As shown, one end of the column 42 located outside the connecting pipe 41 is hinged with an elastic rod 421. A straight groove 422 is opened on the elastic rod 421. A limiting post 423 is fixedly connected to the bottom of the support plate 21. The bottom of the limiting post 423 is movably engaged inside the straight groove 422.

[0044] Using the above scheme, medical staff can pull the elastic rod 421 under the limit of the limiting column 423 and drive the column 42 to move. One end of the elastic rod 421 extends to the end of the second tray 21. Therefore, when the operator rotates the second tray 21 away from the end of the first tray 11, the medical staff can also easily pull the elastic rod 421 to rotate.

[0045] like Figure 1 , Figure 4 , Figure 5 , Figure 9 and 10 As shown, the elastic cable tie 5 is fixedly connected to a channel 41; the top of the channel 3 412 extends into the interior of the tray 11 and is connected to the elastic cable tie 5 through the channel 41.

[0046] The elastic cable tie 5 has two sealed ends and is divided into upper and lower parts. The upper part of the elastic cable tie 5 is installed on one of the retaining rings 12, and the lower part of the elastic cable tie 5 is installed on the tray 11. When the retaining ring 12 is closed, the elastic cable tie 5 can be in a ring shape.

[0047] The upper end of the elastic cable tie 5 is inverted triangular, and the lower end of the elastic cable tie 5 is inverted triangular groove and can be engaged with the upper end of the elastic cable tie 5.

[0048] Using the above method, after the patient's arm is fixed on the support plate 11 by closing the elastic block 13, the elastic band 5 can be made into a ring shape and wrapped around the patient's arm. At this time, hydraulic oil is injected into the elastic band 5 through the channel 3 412 and the channel 4 51, which will cause the elastic band 5 to expand and squeeze the patient's arm, thereby producing an effect similar to a tourniquet, and making the blood vessels in the patient's arm clearer, thus facilitating the accuracy of puncture by medical staff.

[0049] like Figure 1 , Figures 3-5 , Figure 7 and Figure 10As shown, a cam 312 is also fixedly connected to one end of the piston rod 31; a pressure block 6 that can move in the vertical direction is also movably connected inside the support plate 11, and an arc groove 61 is provided in the middle of the pressure block 6; when the piston rod 31 rotates around the axis, the cam 312 can squeeze the arc groove 61 upward.

[0050] By adopting the above scheme, when the second support plate 21 rotates, the hinge of the piston rod 31 also rotates, thereby driving the cam 312 to rotate and squeeze the bottom of the pressure block 6 to force the pressure block 6 to move upward, thereby increasing the pressure between the first support plate 11 and the arc groove 61 on the patient's arm, further avoiding the patient's shaking during puncture, and further increasing the stability of medical staff in the process of puncturing the patient.

[0051] Working principle and usage process of this invention:

[0052] First, medical staff place the patient's arm on tray 11. By rotating the retaining ring 12, the elastic locking block 13 engages with tray 11 to fix the patient's arm. At the same time, the Velcro 23 fixes the patient's hand to the support block 22, keeping it in a semi-clenched state, with the back of the hand exposed. Then, medical staff pull the column 42 to connect channel 1 311 through connector 44, channel 2 411, three-way port 43, channel 3 412, and elastic cable tie 5. At this time, rotating tray 21 will cause the patient's wrist to rotate downward. During the rotation of tray 21, sleeve 32 discharges the hydraulic oil in piston rod 31 through channel 1 311 and connector 4 into elastic cable tie 5. Then, closing connector 4 will fix the angle of tray 21, and the patient's arm and hand will form an angle, which can also prevent the patient's hand from shaking, thereby increasing the stability of the medical staff when puncturing the patient's hand.

[0053] As the elastic block 13 closes and fixes the patient's arm on the support plate 11, the elastic band 5 can be looped around the patient's arm. At this time, hydraulic oil is injected into the elastic band 5 through the channel 3 412 and the channel 4 51, which will cause the elastic band 5 to expand and squeeze the patient's arm, thus producing an effect similar to a tourniquet, and making the blood vessels in the patient's arm clearer, thereby facilitating the accuracy of puncture by medical staff.

[0054] Simultaneously, as the second support plate 21 rotates, the hinge of the piston rod 31 also rotates, thereby driving the cam 312 to rotate and squeeze the bottom of the pressure block 6 to force the pressure block 6 to move upward, thereby increasing the pressure between the first support plate 11 and the arc groove 61 on the patient's arm, preventing it from shaking during puncture, and further increasing the stability of the puncture during the puncture process for medical staff.
