Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically an integrated foldable intravenous puncture arm auxiliary fixation device. Background Technology

[0002] A medium-length catheter is a vascular access device inserted through a relatively large vein in the arm. It is mainly used for short- to medium-term intravenous infusion therapy lasting more than 7 days. The catheter tip is positioned at the level of the armpit. It features protection of the blood vessel and avoids the pain of repeated punctures.

[0003] Chinese Patent Publication No. CN221831072U discloses an arm fixation device for intravenous puncture, including a lifting assembly operating table connected to the lifting assembly, a bracket disposed on the operating table and arranged along the width direction of the operating table, a flexible pad on the bracket, and at least two spaced fixing bolts on the bracket for fixing the patient's arm. The lifting assembly includes a first housing with a cavity inside, a lifting screw rotatably disposed within the first housing, a lifting rod rotatably connected to the lifting screw, one end of the lifting rod extending outside the first housing and having the operating table disposed thereon, and a driving component disposed in the first housing and connected to the lifting screw for driving the lifting screw to rotate.

[0004] When nurses encounter difficult veins during punctures in a patient's arm, their arms become strained and unstable. However, the aforementioned device cannot provide auxiliary support for the nurse's arm or elbow during use. Therefore, the nurse's arm can only remain suspended during puncture. Furthermore, the device cannot be folded after use, so it takes up a lot of space when stored. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art, which is that it cannot provide auxiliary support for the nurse's arm or elbow during use, so the nurse's arm can only be kept suspended during puncture, and the device cannot be folded after use, so it occupies a lot of space when stored.

[0006] An integrated foldable intravenous puncture arm auxiliary fixation device is proposed, comprising a fixation plate for fixing the position, a first support plate for supporting the patient's arm, a second support plate for extending the length of the first support plate, fixing bolts for fixing the first support plate, a folding assembly for raising the height of a third support plate, and a third support plate for supporting the nurse's arm. The fixation plate is located at one end of the first support plate and is connected to the first support plate. The second support plate is located at the other end of the first support plate and is connected to the first support plate. There are two fixing bolts, each connected to one end of the second support plate. The two fixing bolts are respectively located on both sides of the second support plate and are connected to the first support plate. The folding assembly is located below the second support plate and is slidably connected in a preset groove in the second support plate. The third support plate is located above the folding assembly and is connected to the folding assembly.

[0007] In this invention, after loosening the straps, the first or second support plate can be rotated. Once the first and second support plates are connected together using fixing bolts, a fixing plate can be used to secure the connected first and second support plates to the operating table. The patient's arm is then placed on the support plate, and the folding assembly is pushed out laterally from under the second support plate, lifting the third support plate to a specified height. The nurse can then place their dominant arm or elbow on the third support plate for stability. The nurse can then perform puncture on the patient's arm placed on the first and second support plates. After use, the folding assembly and fixing plate can be returned to their original positions, the fixing bolts can be loosened, and the first and second support plates can be folded together and secured with straps. This addresses the shortcomings mentioned in the background, such as the inability to provide auxiliary support for the nurse's arm or elbow during use, resulting in the nurse's arm being suspended during puncture, and the inability to fold the device after use, leading to significant space requirements during storage.

[0008] In a preferred embodiment of the present invention, one end of the fixing plate is connected to a damping rotator, and the fixing plate is connected to the first support plate through the damping rotator. After the fixing plate is fixed on the operating table, the first support plate and the second support plate can utilize the angle between the damping rotator and the operating table to better fit the patient's arm.

[0009] In a preferred embodiment of the present invention, one side of the first tray is provided with a strap, and one end of the strap is attached to the first tray. After the first tray and the second tray are used and folded together, the strap can be used to tie the first tray and the second tray together, thereby facilitating storage and movement.

[0010] In a preferred embodiment of the present invention, the middle section of the strap is provided with a hook and loop fastener and the end of the strap is provided with a soft hook and loop fastener. The hook and loop fastener and the soft hook and loop fastener are respectively connected to the upper and lower surfaces of the strap. The hook and loop fastener has high strength, so it will not suddenly open when the first tray and the second tray are moved. Furthermore, the hook and loop fastener can be opened and closed multiple times without reducing its strength.

[0011] In a preferred embodiment of the present invention, the end of the first support plate is provided with two protrusions. After the first support plate and the second support plate are opened, the first support plate and the second support plate can be connected and fixed together using fixing bolts, thereby extending the length of the entire support plate and preventing the patient's forearm from being suspended in the air during puncture.

[0012] In a preferred embodiment of the present invention, a bidirectional slide rail is provided at both ends of the folding component, and the folding component is connected to the second tray through the bidirectional slide rail. The folding component can slide out from both sides of the second tray using the bidirectional slide rail, thereby ensuring that the nurse's hands can be used.

[0013] In a preferred embodiment of the present invention, the folding assembly includes a sliding plate, a scissor arm, a lifting plate, and a locking assembly. The sliding plate is slidably connected to the second support plate via a bidirectional slide rail. The lifting plate is positioned above the sliding plate. The scissor arm is vertically positioned between the lifting plate and the sliding plate. Two hinged ends of one end of the scissor arm are respectively hinged to the lifting plate and the sliding plate. Two sliding ends of the other end of the scissor arm are respectively slidably positioned on the lifting plate and the sliding plate. The locking assembly is positioned on the sliding plate and connected to the sliding ends of the scissor arm. The folding assembly can adjust the height of the third support plate vertically, thereby ensuring that the third support plate does not cause the nurse's arm to be too low or too high during use.

[0014] In a preferred embodiment of the present invention, the locking assembly includes a housing, a pressure rod, a first spring, a fixed housing, a locking block, a second spring, and a baffle. Two housings are slidably mounted on a sliding plate. The sliding end of the scissor arm is hinged to the two housings. The pressure rod is slidably mounted inside the housing. Each housing has a first spring inside, and the two first springs are sleeved on the pressure rod. The fixed housing is connected to the middle position of the pressure rod. The locking block is vertically slidably mounted inside the fixed housing. Two second springs are vertically mounted above the locking block, and the two second springs are respectively mounted on both sides of the locking block. The baffle is located below the fixed housing and connected to the sliding plate, and the locking block is connected to the baffle. After the folding assembly adjusts the height of the third tray, the locking assembly locks the height of the third tray, thereby preventing the third tray from suddenly falling when the nurse is using it.

[0015] In a preferred embodiment of the present invention, the baffle is provided with multiple slots, and an angle is provided between the contact surfaces of the slots and the blocks, so that the third support plate can be lifted directly when the third support plate is raised.

[0016] The advantages of this utility model compared with the prior art are:

[0017] When a nurse performs a puncture on a patient's arm, the third support plate can provide auxiliary support for the nurse's arm or elbow, thereby preventing the nurse's arm from being suspended in the air during the puncture and ensuring the stability of the nurse's arm during the puncture. After the puncture is completed, the first and second support plates can be folded up and then tied together with straps, making it convenient for medical staff to store or move.

Detailed Implementation

[0030] The following will refer to the appendix in the embodiments of this utility model. Figure 1-11 The technical solutions in the embodiments of this utility model will be described in detail below.

[0031] like Figure 1-5 As shown, the integrated foldable intravenous puncture arm auxiliary fixation device includes a fixation plate 1 for fixing the position, a first support plate 2 for supporting the patient's arm, a second support plate 3 for extending the length of the first support plate 2, a fixing bolt 4 for fixing the first support plate 2, a folding assembly 5 for raising the height of the third support plate 6, and a third support plate 6 for supporting the nurse's arm. A groove is provided below the first support plate 2, and the fixation plate 1 is set in the groove below the first support plate 2 along the length direction of the first support plate 2.

[0032] like Figure 1-5 As shown, a damping rotator 11 is provided at one end of the fixed plate 1. The damping rotator 11 is fixedly connected to the first support plate 2 by screws, but the output end of the damping rotator 11 is connected to the fixed plate 1. Therefore, the fixed plate 1 can be rotated out from under the first support plate 2, thereby adjusting the angle between the fixed plate 1 and the first support plate 2. The second support plate 3 is located at the other end of the first support plate 2 and is connected to the first support plate 2 by a hinge. Therefore, when the first support plate 2 remains stationary, the second support plate 3 can be rotated by the hinge.

[0033] like Figure 1-5 As shown, a strap 7 is provided on one side of the first tray 2. One end of the strap 7 is glued to the side plate of the first tray 2, and the other end of the strap 7 is provided with a Velcro soft surface 72. A Velcro barbed surface 71 is provided in the middle section of the strap 7. The Velcro barbed surface 71 and the Velcro soft surface 72 are respectively sewn on the upper and lower surfaces of the strap 7. Therefore, when the first tray 2 and the second tray 3 are folded together, the strap 7 can be used to wrap around the first tray 2 and the second tray 3.

[0034] like Figure 1-5As shown, the end of the strap 7 is then attached to the hooked side 71 of the middle section of the strap 7 using the hooked side 72 of the hooked side, thereby fixing the folded first tray 2 and second tray 3, so that the folded first tray 2 and second tray 3 are easier to store and move. There are two fixing bolts 4, both of which are located at one end of the second tray 3 at the hinge, and the two fixing bolts 4 are respectively located on both sides of the second tray 3. Both fixing bolts 4 are threaded onto the second tray 3.

[0035] like Figure 1-5 As shown, the first support plate 2 has two protrusions 21 on the end face of one end of the hinge. Both protrusions 21 are glued to the first support plate 2. The second support plate 3 has grooves corresponding to the two protrusions 21 on the end face of one end of the hinge. After the first support plate 2 and the second support plate 3 are opened, the protrusions 21 on the end face of the first support plate 2 can be rotated into the grooves on the end face of the second support plate 3. The ends of the two fixing bolts 4 pass through the second support plate 3 and are set in the grooves on the end face of the second support plate 3.

[0036] like Figure 1-5 As shown, the sides of the two protrusions 21 are provided with grooves corresponding to the fixing bolts 4. Therefore, after the protrusions 21 on the first support plate 2 are rotated into the grooves of the second support plate 3, the two fixing bolts 4 can be tightened until the ends of the fixing bolts 4 are inserted into the grooves on the sides of the protrusions 21, thus restricting the position of the second support plate 3 and preventing the second support plate 3 from falling suddenly during use. The bottom of the second support plate 3 is provided with a groove for placing the folding component 5.

[0037] like Figure 1-5 As shown, the folding assembly 5 is disposed in the groove below the second tray 3, and is located on one side of the fixing bolt 4. Both ends of the folding assembly 5 are provided with bidirectional slide rails 8. The fixed ends of the bidirectional slide rails 8 are fixedly connected to the two side plates of the groove below the second tray 3 by screws, and the moving ends of the bidirectional slide rails 8 are connected to the folding assembly 5 by screws. Therefore, the folding assembly 5 can slide out from below the second tray 3. The third tray 6 is disposed above the folding assembly 5 and connected to the folding assembly 5.

[0038] like Figure 1-5 As shown, when the folding component 5 slides out horizontally, it can drive the third support plate 6 to slide out simultaneously. The folding component 5 can be adjusted up and down. Since the third support plate 6 is connected to the folding component 5, when the folding component 5 is adjusted up and down, it can drive the third support plate 6 to move up and down simultaneously. After the third support plate 6 moves to a suitable height, it can be used to support the nurse's arm.

[0039] like Figure 6As shown, the folding assembly 5 includes a sliding plate 51, scissor arms 52, a lifting plate 53, and a snap-fit ​​assembly 9. The sliding plate 51 is located in a groove below the second support plate 3, and the moving ends of the two bidirectional slide rails 8 are connected to the end plates at both ends of the sliding plate 51 by screws. Therefore, the sliding plate 51 can slide out laterally from below the second support plate 3. The lifting plate 53 is located above the sliding plate 51, and the third support plate 6 is fixedly connected to the lifting plate 53 by screws. There are two scissor arms 52, both of which are vertically arranged between the lifting plate 53 and the sliding plate 51.

[0040] like Figure 6 As shown, the two ends of the two scissor arms 52 can be divided into hinged ends and moving ends. The upper and lower hinged ends of the two scissor arms 52 are respectively hinged to the lifting plate 53 and the sliding plate 51. The upper moving ends of the two scissor arms 52 are slidably arranged in the preset sliding groove of the lifting plate 53, and the lower moving ends of the two scissor arms 52 are slidably arranged on the sliding plate 51. The lower moving ends of the two scissor arms 52 are connected to the snap-fit ​​component 9. When the moving ends of the scissor arms 52 slide, they can drive the lifting plate 53 to move up and down to adjust the height.

[0041] like Figure 6 As shown, since the third support plate 6 is fixedly connected to the lifting plate 53, when the lifting plate 53 is moved up and down by the scissor arm 52 to adjust its height, it will drive the third support plate 6 to move up and down synchronously. After the lifting plate 53 and the third support plate 6 are adjusted to a suitable height, the height of the lifting plate 53 and the third support plate 6 can be locked by the snap-fit ​​component 9, thereby preventing the lifting plate 53 and the third support plate 6 from falling suddenly.

[0042] like Figure 7-11 As shown, the snap-fit ​​assembly 9 includes a housing 91, a pressure rod 92, a first spring 93, a fixing box 94, a snap-fit ​​block 95, a second spring 96, and a baffle 97. Two housings 91 are slidably mounted on a sliding plate 51, and the two housings 91 are respectively located on both sides of the sliding plate 51. Two grooves for guiding the two housings 91 are provided on the bottom plate of the sliding plate 51. The two housings 91 are slidably mounted in the grooves on the bottom plate of the sliding plate 51, and the sliding plates 51 below the two scissor arms 52 are respectively hinged to the two housings 91.

[0043] like Figure 7-11 As shown, the moving end of the scissor arm 52 can drive the box 91 to slide synchronously when sliding. The pressure rod 92 is horizontally arranged on the sliding plate 51. The side plate of the sliding plate 51 is provided with a guide groove for guiding the pressure rod 92. The pressure rod 92 is horizontally arranged in the guide groove, and both ends of the pressure rod 92 pass through the guide groove and are both arranged on the outside of the two sides of the sliding plate 51. Both boxes 91 are slidably connected to the pressure rod 92. Each box 91 has a first spring 93 horizontally arranged inside.

[0044] like Figure 7-11 As shown, both first springs 93 are sleeved on the pressure rod 92, and the two ends of the two first springs 93 are respectively connected to the pressure rod 92 and the housing 91. Therefore, when the pressure rod 92 is pressed laterally, both first springs 93 will undergo elastic deformation and store force. Then, when the pressure rod 92 is released, the first springs 93 can return the pressure rod 92 to its original position. The fixed housing 94 is set in the middle position of the pressure rod 92 and is glued to the pressure rod 92. Therefore, when the pressure rod 92 slides laterally, it will drive the fixed housing 94 to slide synchronously.

[0045] like Figure 7-11 As shown, the locking block 95 is vertically slidably disposed inside the fixed box 94 and is locked onto the fixed box 94. The locking block 95 is disposed below the fixed box 94 and connected to the baffle 97. There are two second springs 96, both of which are vertically disposed inside the fixed box 94. Both second springs 96 are disposed above the locking block 95 and respectively disposed on both sides of the locking block 95. Both ends of the two second springs 96 are connected to the fixed box 94 and the locking block 95. Therefore, when the locking block 95 moves upward, it will compress the second springs 96. At this time, the second springs 96 will deform and store force.

[0046] like Figure 7-11 As shown, the accumulated force will then be used to bounce the locking block 95 back to its original position. The lower end of the locking block 95 has an inclined surface. The baffle 97 is set below the locking block 95 and is attached to the sliding plate 51. The baffle 97 has multiple slots for locking the locking block 95. The slots also have inclined surfaces, and the inclined surfaces on the slots are in contact with the inclined surfaces on the locking block 95. The direction of the inclined surface on the locking block 95 is the direction of the movement of the scissor arm 52 when the lifting plate 53 moves upward, while the direction of the inclined surface on the slot is the direction of the movement of the scissor arm 52 when the lifting plate 53 moves downward.

[0047] like Figure 7-11 As shown, when the lifting plate 53 moves upward, the inclined surface of the slot guides the block 95, causing the block 95 to move upward. Then, in the next slot, the second spring 96 will spring the block 95 into the slot again, and this process is repeated until the lifting plate 53 stops moving upward. When the lifting plate 53 needs to move downward, simply press the pressure rod 92. When the pressure rod 92 moves to one side, the fixing box 94 will drive the block 95 to move to one side synchronously.

[0048] like Figure 7-11As shown, once the locking block 95 is removed from the slot of the baffle 97, the lifting plate 53 can move downwards. After the lifting plate 53 moves downwards to the required height, the pressure rod 92 is released, and the pressure rod 92 is bounced back to its original position by the first spring 93. During the reset process, the pressure rod 92 can once again use the fixing box 94 to drive the locking block 95 to move into the slot of the baffle 97, thereby preventing the scissor arm 52 from continuing to slide, thus limiting the height of the lifting plate 53.

[0049] The movement process in this embodiment is as follows: After the strap 7 is opened, the second support plate 3 can be rotated downwards until the protrusion 21 on the first support plate 2 is rotated into the groove of the second support plate 3. Then, the two fixing bolts 4 can be turned forward to connect the first support plate 2 and the second support plate 3 together. Then, the fixing plate 1 is rotated out from under the first support plate 2 and inserted under the operating table mattress for fixation. Then, according to the position of the patient's arm, the first support plate 2 is rotated to change the angle between the first support plate 2 and the operating table.

[0050] After rotating the first tray 2 to the appropriate angle, the patient's arm can be placed on the first tray 2 and the second tray 3. Then, the folding component 5 can be slid out according to the nurse's dominant hand. After the sliding plate 51 has slid out completely, the third tray 6 can be lifted up to the desired height. Then, the nurse can place her arm on the third tray 6 to perform the puncture on the patient. After the puncture is completed, the patient's arm can be removed from the first tray 2 and the second tray 3.

[0051] Then press the lever 92 to reset the third support plate 6 to its original position, and slide the sliding plate 51 back under the second support plate 3. Then, remove the fixing plate 1 from under the mattress and screw the fixing plate 1 back under the first support plate 2. Then, twist the fixing bolt 4 in the opposite direction and fold the first support plate 2 and the second support plate 3 together. Finally, use the straps 7 to tie the first support plate 2 and the second support plate 3 together.

[0052] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
