Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular is a hand fixing device for infusion nursing of psychiatric patients. Background Art

[0002] Traditional infusion operations are usually carried out with the cooperation of ordinary patients, and medical staff can complete the steps of puncture, fixation, and adjustment of drip rate relatively smoothly. However, due to the particularity of their mental state, psychiatric patients often show restlessness, uncooperativeness, and even resistance to treatment. This makes it difficult to perform intravenous puncture, which in turn increases the risk of puncture failure, and easily leads to vascular damage and increased pain for patients. In the existing method, medical staff usually use devices such as straps to fix the patient's arm or to the bracket of the seat to prevent the arm from shaking. At this time, medical staff can perform puncture through the patient's hand relatively stably. However, in the actual operation process, since the patient's hand is not fixed, the medical staff still needs to free up one hand to counter the shaking of the patient's hand, but this method will greatly affect the medical staff's puncture operation on the patient. Based on this, we propose a hand fixation device for infusion care of psychiatric patients. Summary of the invention

[0003] In order to solve the problems raised in the above background technology, the present invention provides a hand fixing device for infusion care of psychiatric patients, which solves the problem that the patient's non-cooperation will affect the puncture of medical staff when puncturing the hand of a psychiatric patient.

[0007] The telescopic rod comprises a piston rod hinged to the bottom of the first support plate, a sleeve is hinged to the bottom of the second support plate, one end of the sleeve extends to the inside of the piston rod and is movably connected to the piston rod, and hydraulic oil is stored inside the piston rod;

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

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

[0010] Preferably, a channel 1 is provided at one end of the piston rod; the connecting assembly comprises a connecting tube fixedly connected to the bottom of the support plate 1, a column is elastically connected inside the connecting tube, one end of the column extends to the outside of the connecting tube and is spline-connected to the connecting tube, a channel 3 and a channel 2 are provided on the connecting tube, a connecting piece is also fixedly connected to the connecting tube, the channel 1 and the channel 2 are connected through the connecting piece, a three-way port is also provided on the column, in the initial state, the column is subjected to the tension of the tension spring part so that the three-way port is respectively misaligned with the channel 2 and the channel 3, and the top end of the channel 3 is connected with the elastic cable tie;

[0011] The connecting piece is filled with hydraulic oil and is a bellows or a hose.

[0013] Preferably, the elastic cable tie is fixedly connected with a channel four; the top of the channel three extends to the inside of the support plate one and is connected with the elastic cable tie through the channel four.

[0014] Preferably, the elastic tie has two sealed ends and is divided into upper and lower parts, wherein the upper part of the elastic tie is installed on one of the rings, and the lower part of the elastic tie is installed on a support plate, so that the elastic tie can be ring-shaped as a whole when the ring is closed.

[0015] Preferably, the upper end of the elastic cable tie is in an inverted triangle shape, and the lower end of the elastic cable tie is in an inverted triangle groove shape and can be engaged 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 which can move in the vertical direction is movably connected inside the support plate, and an arc groove is opened in the middle of the pressure block; when the piston rod rotates around the axis, the cam can squeeze the arc groove upward.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

At this time, rotating the second support plate will drive the patient's wrist to rotate downward. During the rotation of the second support plate, the sleeve discharges the hydraulic oil in the piston rod through channel one and the connecting component into the elastic cable tie. Then, closing the connecting component will fix the angle of the second support plate, and the patient's arm and hand will present 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 on the support plate 1 by closing the elastic block, so that the elastic strap is in a ring shape and surrounds the patient's arm. At this time, hydraulic oil is injected into the elastic strap through the channel 3 through the channel 4, which makes the elastic strap expand and squeeze the patient's arm, thereby producing an effect similar to that of a compression cuff and making the blood vessels in the patient's arm clearer, thereby facilitating the accuracy of medical staff in puncturing the patient.

[0020] The above scheme causes the hinge of the piston rod to rotate when the second support plate rotates, thereby driving the cam to rotate and squeeze the bottom of the pressure block to force the pressure block upward, thereby increasing the pressure on the patient's arm between the first support plate and the arc groove, avoiding its shaking during puncture, and further increasing the stability of medical staff during the puncture of the patient.

[0033] like Figures 1 to 10 As shown, the present invention provides a hand fixing device for infusion nursing of psychiatric patients, comprising an arm support plate assembly 1 and a support plate assembly 2, and further comprising: a telescopic rod 3, which is arranged at the bottom of the arm support plate assembly 1 and is used to adjust the angle between the arm support plate assembly 1 and the support plate assembly 2; an elastic tie 5, which is installed on the arm support plate assembly 1; a connecting assembly 4, which is arranged at the bottom of the arm support plate assembly 1 and is used to control the connection between the telescopic rod 3 and the elastic tie 5;

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

[0035] The support plate assembly 2 includes a support plate 21 hinged to the end of the support plate 1 11, a support block 22 is fixedly connected to the support plate 21, and a Velcro 23 is provided on the support block 22;

[0036] The telescopic rod 3 includes a piston rod 31 hinged to the bottom of the first support plate 11, a sleeve 32 is hinged to the bottom of the second support plate 21, one end of the sleeve 32 extends to the inside of the piston rod 31 and is movably connected to the piston rod 31, and hydraulic oil is stored inside the piston rod 31;

[0037] Adjusting the connecting component 4 and rotating the second support plate 21 can enable 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 1 311 is opened at one end of the piston rod 31;

[0038] The connecting assembly 4 includes a connecting tube 41 fixedly connected to the bottom of the support plate 11, a column 42 is elastically connected inside the connecting tube 41, one end of the column 42 extends to the outside of the connecting tube 41 and is spline-connected to the connecting tube 41, a channel 3 412 and a channel 2 411 are provided on the connecting tube 41, a connecting piece 44 is also fixedly connected to the connecting tube 41, the channel 1 311 and the channel 2 411 are connected through the connecting piece 44, a three-way port 43 is also provided on the column 42, in the initial state, the column 42 is subjected to the tension of the tension spring part thereof so that the three-way port 43 is respectively misaligned with the channel 2 411 and the channel 3 412, and the top end of the channel 3 412 is connected with the elastic tie 5;

[0039] The connecting piece 44 is filled with hydraulic oil and is a bellows or a hose, thereby ensuring that when the telescopic rod 3 rotates relative to the support plate 1 11, the second channel 411 and the first channel 311 can be stably connected;

[0040] By adopting the above scheme, the medical staff places the patient's arm on the support plate 11, rotates the holding ring 12 to make the elastic block 13 engage with the support plate 11 to fix the patient's arm, and fixes the patient's hand on the support block 22 through the Velcro 23 and keeps it in a half-gripped state, while the back of the hand is exposed. Then the medical staff pulls the column 42 to connect the channel 1 311 through the connecting piece 44, the channel 2 411, the three-way port 43, the channel 3 412 and the elastic tie 5. At this time, rotating the support plate 21 will drive the patient's wrist to rotate downward. During the rotation of the support plate 21, the sleeve 32 discharges the hydraulic oil in the piston rod 31 through the channel 1 311 and the connecting component 4 into the elastic tie 5. Then closing the connecting component 4 will fix the angle of the support plate 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.

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

[0042] By adopting the above scheme, the patient's thumb is placed under the cross bar 221 to limit the patient's thumb in the vertical direction, and the base of the patient's hand is made to fit with the cross bar 221. At the same time, a baffle 222 is provided to limit the patient's thumb in the horizontal direction, further preventing the patient's hand from shaking.

[0043] like Figure 3-Figure 8 As shown, one end of the column 42 located outside the connecting pipe 41 is hinged with an elastic rod 421, and a straight slot 422 is provided on the elastic rod 421. The bottom of the arm support plate assembly 1 is fixedly connected to a limiting column 423, and the bottom of the limiting column 423 is movably clamped in the straight slot 422;

[0044] By adopting the above scheme, medical staff can pull the elastic rod 421 under the limit of the limit column 423 and drive the column 42 to move, and one end of the elastic rod 421 extends to the end of the second pallet 21. Therefore, when the operator rotates the second pallet 21 away from the end of the first pallet 11, the medical staff can also conveniently pull the elastic rod 421 to rotate.

[0045] like Figure 1 , Figure 4 , Figure 5 , Fig. 9 and 10 As shown, the elastic tie 5 is fixedly connected with a channel 4 51; the top of the channel 3 412 extends to the inside of the support plate 11 and is connected with the elastic tie 5 through the channel 4 51;

[0046] The elastic cable tie 5 has two sealed ends and is divided into an upper and lower part, wherein the upper part of the elastic cable tie 5 is mounted on one of the rings 12, and the lower part of the elastic cable tie 5 is mounted on a support plate 11. When the ring 12 is closed, the elastic cable tie 5 can be in a ring shape as a whole;

[0047] The upper end of the elastic tie 5 is in an inverted triangle shape, and the lower end of the elastic tie 5 is in an inverted triangle groove shape and can be engaged with the upper end of the elastic tie 5;

[0048] By adopting the above scheme, after the patient's arm is fixed on the support plate 11 by closing the elastic block 13, the elastic strap 5 can be ring-shaped as a whole and surround the patient's arm. At this time, hydraulic oil is injected into the elastic strap 5 through the channel 4 51 from the channel 3 412 to make the elastic strap 5 expand and squeeze the patient's arm part, thereby producing an effect similar to a compression cuff and making the blood vessels in the patient's arm part clearer, thereby facilitating the accuracy of medical staff when puncturing the patient.

[0049] like Figure 1 , Figure 3-Figure 5 , Figure 7 and Fig.10As shown, a cam 312 is fixedly connected to one end of the piston rod 31; a pressing block 6 which can move in the vertical direction is also movably connected inside the support plate 11, and an arc groove 61 is opened in the middle of the pressing 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 support plate 21 rotates, the hinge of the piston rod 31 will also rotate, thereby driving the cam 312 to rotate and squeeze the bottom of the pressing block 6 to force the pressing block 6 to move upward, thereby increasing the pressure on the patient's arm between the support plate 11 and the arc groove 61, further avoiding the patient's shaking during puncture, and further increasing the stability of medical staff during the puncture of the patient.

[0051] The working principle and use process of the present invention:

[0052] First, the medical staff places the patient's arm on the support plate 11, and fixes the patient's arm by rotating the holding ring 12 to make the elastic block 13 engage with the support plate 11, and at the same time fixes the patient's hand on the support block 22 through the Velcro 23 and keeps it in a half-gripped state, with the back of the hand exposed. Then the medical staff pulls the column 42 to connect the channel 1 311 through the connecting piece 44, the channel 2 411, the three-way port 43, the channel 3 412 and the elastic cable tie 5. At this time, rotating the support plate 21 will drive the patient's wrist to rotate downward. During the rotation of the support plate 21, the sleeve 32 discharges the hydraulic oil in the piston rod 31 into the elastic cable tie 5 through the channel 1 311 and the connecting component 4. Then, closing the connecting component 4 will fix the angle of the support plate 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] Since the elastic block 13 is closed and the patient's arm is fixed on the support plate 11, the elastic strap 5 can be made into a ring shape and surround the patient's arm. At this time, the hydraulic oil injected into the elastic strap 5 through the channel 4 51 from the channel 3 412 will cause the elastic strap 5 to expand and squeeze the patient's arm, thereby producing an effect similar to that of a compression cuff and making the blood vessels in the patient's arm clearer, thereby facilitating the accuracy of the medical staff's puncture of the patient.

[0054] At the same time, when the 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 pressing block 6 to force the pressing block 6 to move upward, thereby increasing the pressure on the patient's arm between the support plate 11 and the arc groove 61, avoiding its shaking during puncture, and further increasing the stability of medical staff during puncture of the patient.
