Description

Technical Field

[0001] The utility model relates to the field of auxiliary instruments for injection, and more specifically to an upper limb supporting bracket for injection. Background Art

[0002] At present, enhanced CT scanning is performed by injecting liquid medicine into the body through veins. During intravenous puncture and injection, in order to improve the success rate of injection and make the lesion site appear more clearly, the examinee is required to straighten one upper arm. Since the upper arm is suspended in the air for a long time without support, it is easy to get fatigued and cause tremors or flexion, which can cause the needle to pierce the vein and cause drug extravasation, making it difficult to clearly display the lesion site, affecting the enhanced scanning effect and not conducive to disease diagnosis. Sometimes, due to drug extravasation, re-puncture and injection of drugs are required, causing additional financial burden and pain to the examinee. At present, in order to meet the needs of the above-mentioned injections and meet the needs of different patients, arm supports with lifting adjustments are commonly used for effective support. However, the current adjustment structure mostly uses a locking knob for locking, and the adjustment part is in the middle of the support, requiring bending over to adjust, or even multiple adjustments back and forth, which is inconvenient to operate and needs to be improved.

[0028] Furthermore, a first connecting portion is provided at the end of the outer sleeve of the gas spring, and a first socket is provided at the first connecting portion; a second connecting portion is provided at the end of the piston rod of the gas spring, and a second socket is provided at the second connecting portion; a third socket is correspondingly provided at the bottom of the supporting sleeve, and a fourth socket is correspondingly provided at the top of the lifting sleeve; the diameter of the outer sleeve of the gas spring is smaller than the inner diameter of the lifting sleeve, and the gas spring is installed inside the supporting sleeve, and the supporting sleeve and the bottom of the outer sleeve are connected by bolts inserted through the third socket and the first socket; the top of the lifting sleeve and the end of the piston rod are connected by bolts inserted through the fourth socket and the second socket.

[0029] Furthermore, the outer wall of the support sleeve 310 is provided with a guide hole 311 arranged along the length direction, and the top of the guide hole is lower than the top surface of the support sleeve; the outer wall of the lifting sleeve 320 is provided with a first threaded hole for mounting a guide bolt 340, and the head of the guide bolt slides along the inner wall of the guide hole. This structural design can further strengthen the sliding fit between the lifting sleeve and the support sleeve, strengthen the movement limit, and prevent the lifting sleeve from separating from the support sleeve. It can also prevent the lifting sleeve from rotating, avoiding damage to the gas spring due to force applied in a non-axial direction.

[0030] Furthermore, if Figure 3 、 Figure 4 As shown, the adjustment structure 400 includes a handle 410 and a cable 420; the handle 410 is slidably installed at the bottom of one end of the support plate 200, and one end of the cable 420 is connected to the end of the handle 410; the other end is movably passed through the top side wall of the lifting sleeve 320 through the wire hole, and the end is connected to the control element of the gas spring 330; through the connection of the handle, the cable and the control element, the adjustment operating part can be moved to the bottom end of the support plate, which is convenient for grasping for adjustment and use; and the handle is installed at the bottom of one end of the support plate, which is more convenient for grasping, adjusting and using; it should be noted that the controllable gas spring is a common structural device on the market, which has its own control element for adjustment, and the specific structure will not be repeated.

[0031] Furthermore, if Figure 6As shown, a support block 210 is fixedly provided at one end of the bottom surface of the support plate 200, and at least two through holes 220 are provided on the support block 210; Figure 5 As shown, a pad 430 is fixed on the top surface of one end of the handle 410 close to the center of the support plate, and at least two second threaded holes 440 are provided on the pad 430. The positions of the second threaded holes correspond to the positions of the through holes; Figure 4 As shown, a support bolt 450 is passed through the support block 210, and the end of the support bolt 450 is threadedly connected and installed in the second threaded hole 440. The handle is movably installed on the bottom of the support plate through the support bolt and can move along the length direction of the support bolt; a spring 460 is sleeved on the support bolt 450, and the spring 460 is located between the support block 210 and the cushion block 430; the adoption of an assembled structure can facilitate the processing and production of various structural components; and the provision of a spring can facilitate the reset of the handle, so that the cable returns to a loose state, and facilitates the normal reset of the control element of the gas spring, thereby achieving locking and supporting the support plate, so that the support plate can be adjusted to maintain a desired height position;

[0032] Among them, one end of the cable is provided with a first end, and the other end is provided with a second end, and the first end is clamped at the bayonet of the control element of the gas spring; a third threaded hole is provided on the wall surface of the pad near the center of the support plate, and a threaded connection portion is provided on the second end, which can be threadedly connected and installed at the third threaded hole to perform the required assembly connection. By dragging the handle to adjust the cable, the gas spring is controlled and adjusted to realize the lifting and lowering of the support plate;

[0033] It should be noted that the two ends of the cable can be connected to the first end and the second end by binding, or a wire tube can be provided on the first end and / or the second end. During assembly, one end of the cable can be left empty, and after the wire is threaded into place, the empty end can be inserted into the wire tube, and then the wire tube can be clamped to fix the cable and the wire tube.

[0034] Furthermore, if Figure 6 As shown, a guide ring 230 is fixedly provided on the bottom surface of the support plate 200. The guide ring 230 is located between the support block 210 and the lifting sleeve 320. The cable 420 passes through the guide ring 230. The guide ring 230 can further guide and support the cable to prevent it from loosening and falling, thereby maintaining the overall aesthetics. To a certain extent, it can also better transmit the tension so as to effectively adjust and drive the gas spring.

[0035] Furthermore, the top surface of the support plate is concave to form an arc-shaped groove; by providing the groove, the support plate can have the effect of concaving toward the midline, so as to facilitate the placement of the upper limbs, prevent deviation, and facilitate the injection action of medical staff;

[0036] Furthermore, if Figure 2As shown, a pulley is installed on the bottom surface of the base; wherein, the base is a cross-shaped structure, and the bottom surface of the end of each rod of the base is provided with a groove, and the pulley is a ball pulley, which is clamped in the groove and fixed by bolts; the ball of the ball pulley protrudes from the bottom surface of the base, serving as a supporting contact part with the ground, so that the base has a universal movement function, so that the position of the entire bracket can be adjusted, which is convenient for practical use.
