DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Example
[0031] like Figures 1-4As shown in the figure, a fixing rack for infusion proposed by an embodiment of the present utility model includes a left half shell 1 and a right half shell 2. The left half shell 1 and the right half shell 2 are rotatably connected by a rotating shaft. A transparent cover 3 is inlaid and installed on the right half shell 2. One side of the center of the left half shell 1 is fixedly connected with a left half column 4, and one side of the center of the right half shell 2 is fixedly connected with a right half column 5. A sponge pad 6 is adhesively bonded inside the left half shell 1. Two groups of elastic bands 7 are fixedly connected inside the left half shell 1. One end of the left half shell 1 is fixedly connected with a connecting rope 8. One end of the connecting rope 8 is fixedly connected with a snap ring 9. The snap ring 9 is snap-fitted and rotatably connected to a nut 10. A hole is provided on the side wall of the left half shell 1, and a clamping device is installed inside the hole;
[0032] The clamping device includes a screw 11 threadedly connected to the hole. One end of the screw 11 is provided with a top cover 12. A first positioning screw cap 13 and a second positioning screw cap 14 are threadedly connected to the screw 11. One end of the screw 11 is rotatably connected with a cover plate 15 through a bearing. The cover plate 15 has an arc angle. A gasket 16 is fixed inside the cover plate 15;
[0033] The left half shell 1 and the right half shell 2 are rotatably connected by a rotating shaft. This design enables the fixing rack to be easily opened and closed like a clip. In actual use, medical staff can conveniently place the patient's infusion part into it, and then close the fixing rack for fixation, with simple and efficient operation.
[0034] The transparent cover 3 inlaid on the right half shell 2 is made of plastic. It has high transparency, enabling medical staff to clearly observe the internal situation without opening the fixing rack, including the position of the infusion needle, whether there are abnormalities such as redness and swelling at the infusion part, and whether the infusion tube is unobstructed.
[0035] The left half column 4 at the center of the left half shell 1 and the right half column 5 at the center of the right half shell 2 are in the same position, and the two can form a complete cylinder. The threads provided on the column increase the flexibility and stability of its connection or fixation with other components.
[0036] The sponge pad 6 adhesively bonded inside the left half shell 1 has good softness and buffering properties. When the fixing rack is closed, the sponge pad 6 can be in direct contact with the patient's infusion part, reducing the pressure of the fixing rack on the skin, avoiding causing indentations or injuries, and providing a comfortable feeling for the patient.
[0037] The two groups of elastic bands 7 inside the left half shell 1, each group contains two. One has a hook surface of Velcro, and the other has a loop surface of Velcro. This design enables the elastic bands 7 to be flexibly bonded and disassembled according to the thickness and shape of the patient's infusion part, thereby achieving a more fitting and firm fixing effect. For patients of different body types, effective fixation can be provided to ensure that the infusion process will not be affected by slight limb movement.
[0038] The connecting rope 8 at one end of the left half shell 1 is connected to the snap ring 9, and the snap ring 9 is engaged and rotatably connected to the nut 10. This further enhances its stability and prevents the fixing bracket from accidentally falling off or shifting during the infusion process.
[0039] The clamping device installed in the hole on the side wall of the left half shell 1 is very delicate. The screw rod 11 connected by threads can be adjusted in length by rotation, thereby changing the fixing force and position. The top cover 12 can facilitate the manual operation of the screw rod 11. The first positioning screw cover 13 and the second positioning screw cover 14 are respectively arranged outside and inside the left half shell 1. They can not only be fixed to the left half shell 1, but also effectively fasten the position of the screw rod 11 to prevent it from loosening during use. The arc angle cover plate 15 rotatably connected by a bearing can better fit the shape of the infusion site, and the gasket 16 fixed inside increases the friction and buffering effect, further improving the fixing stability and comfort.
[0040] Stably fixing the infusion site is the primary function of this fixing bracket. During the infusion process, the patient may cause the infusion site to shake due to unconscious movements, turning over, or moving the limbs. This fixing bracket can effectively limit the movement range of the infusion site, ensure that the needle always remains in the correct position, and avoid problems such as poor infusion due to needle displacement, leakage of the liquid medicine, or even the needle slipping out of the blood vessel.
[0041] The presence of the transparent cover 3 enables medical staff to observe the infusion progress in real time and intuitively. Without frequently opening the fixing bracket, it is possible to timely detect whether the infusion speed is normal, whether the infusion is about to be completed, and whether there are adverse reactions such as swelling and congestion at the infusion site, so that the infusion speed can be adjusted in time or corresponding treatment measures can be taken.
[0042] The cooperation of the sponge pad 6 and the elastic band 7 can not only provide a comfortable fixing feeling, but also adapt to the individual differences of different patients' infusion sites. For patients with more sensitive skin or longer infusion times, the sponge pad 6 can reduce local pressure and prevent the formation of pressure sores; the elastic band 7 can be adjusted according to the actual situation to ensure that the fixing force is moderate, neither too tight to cause blood circulation obstruction nor too loose to affect the fixing effect.
[0043] The adjustment function of the clamping device enables the fixing bracket to adapt to limbs of different thicknesses and shapes. By rotating the screw rod 11, the fixing tightness can be precisely adjusted to meet the needs of different patients. At the same time, the design of the arc angle cover plate 15 and the gasket 16 can better disperse the pressure and reduce friction and damage to the skin.
[0044] The working principle is as follows:
[0045] First, open the left half shell 1 and the right half shell 2 through the rotating shaft, and place the patient's infusion site inside.
[0046] The internal sponge pad 6 is in direct contact with the patient's infusion site, providing soft support and cushioning to reduce the pressure of the fixing frame on the skin. The two sets of elastic bands 7 are fastened by Velcro and tightened according to the specific conditions of the patient's infusion site to further enhance the fixing effect on the infusion site and prevent unnecessary movement during infusion.
[0047] In the clamping device on the side wall of the left half shell 1, by rotating the screw 11, the cover plate 15 at one end moves inward until it contacts the infusion site and applies appropriate pressure. The first positioning screw cap 13 and the second positioning screw cap 14 are used to fix the position of the screw 11 to prevent it from loosening. The gasket 16 inside the cover plate 15 increases the friction force and improves the stability of fixation.
[0048] Then close the left half shell 1 and the right half shell 2, and use the cylinder formed by the left half column 4 and the right half column 5 to cooperate with the nut 10 for final tightening.
[0049] The transparent cover 3 on the right half shell 2 facilitates medical staff to observe the situation of the infusion site at any time without opening the fixing frame, reducing the interference of the operation on the infusion.
[0050] In short, this infusion fixing frame realizes stable and comfortable fixation of the infusion site through the coordinated action of each component, facilitates the observation of the infusion situation, and ensures the smooth progress of the infusion process.
[0051] As Figure 1 shown, in some embodiments, the left half shell 1 and the right half shell 2 are made of medical plastic shells, and the end face angles of the left half shell 1 and the right half shell 2 are designed with arc angles. Medical plastics usually have good biocompatibility, are not likely to cause allergic reactions or other adverse reactions in the human body, can ensure safety when contacting the patient's skin, the plastic material is relatively light, convenient for operation and use, and also has a certain strength and durability to meet the needs of long-term use. The arc angle can reduce the irritation and scratching of the patient's skin. During use, if the end face is a sharp right angle, it may cause discomfort or even scratches when contacting the skin. The arc angle is smoother and milder, improving the comfort of the patient.
[0052] As Figure 1 shown, in some embodiments, the transparent cover 3 is a plastic cover, which is convenient for observing the internal situation. Its material is light and will not add too much weight to the whole fixing frame, facilitating carrying and use. At the same time, the plastic has a certain flexibility and impact resistance and is not easy to break, and can maintain good integrity during use.
[0053] As Figure 2As shown, in some embodiments, the left half-column 4 and the right half-column 5 are designed to be in the same position. The left half-column 4 and the right half-column 5 can be combined into a cylinder. Threads are provided on both the left half-column 4 and the right half-column 5, and the threads can cooperate with components such as nuts 10 for fastening. After the left half-shell 1 and the right half-shell 2 are closed, through the cooperation of the nut 10 and the threads, the closing tightness of the fixing frame can be further enhanced, preventing accidental opening during use.
[0054] As Figure 3 shown, in some embodiments, a hook-and-loop fastener surface is provided on the left half-shell 1, and a hook-and-loop fastener hair surface is provided on the sponge pad 6 for adhesive bonding and disassembly. This connection method of the hook-and-loop fastener makes the installation and disassembly of the sponge pad 6 very simple. When the sponge pad 6 needs to be replaced, such as when the sponge pad 6 is contaminated, damaged or needs to be cleaned, it can be easily removed for processing, and then quickly reinstalled through the hook-and-loop fastener, saving operation time and improving work efficiency.
[0055] As Figure 2 shown, in some embodiments, there are two elastic bands in a group of the elastic bands 7. The elastic bands are elastic bands. One of the elastic bands 7 has a hook-and-loop fastener surface, and the other has a hook-and-loop fastener hair surface for adhesive bonding and disassembly and fastening; a group of elastic bands 7 includes two elastic bands, which increases the stability and reliability of the fixation. The elastic property enables the elastic bands 7 to adapt to infusion sites of different sizes and shapes, providing appropriate pressure, which neither causes poor blood circulation due to being too tight nor affects the fixation effect due to being too loose.
[0056] One of the elastic bands 7 has a hook-and-loop fastener surface, and the other has a hook-and-loop fastener hair surface. This design facilitates bonding and disassembly. During use, the length and tightness of the elastic bands 7 can be flexibly adjusted according to the actual situation of the infusion site, and then fastening is achieved through the bonding of the hook-and-loop fastener.
[0057] As Figure 2 shown, in some embodiments, after the left half-column 4 and the right half-column 5 are combined into a cylinder, they are fastened with threads by the nut 10. This method is simple and convenient to operate. When fixing, medical staff only need to tighten the nut 10, without the need for complex tools or operation skills, saving time and effort.
[0058] As Figure 4 shown, in some embodiments, the first positioning screw cap 13 and the second positioning screw cap 14 are respectively provided on the outside and inside of the left half-shell 1 for fixing the left half-shell 1 and fastening the position of the screw rod 11 at the same time; the two positioning screw caps located on the outside and inside can provide balanced pressure from both sides, making the connection between the left half-shell 1 and the screw rod 11 more stable. This effectively prevents loosening due to external force or vibration during use, ensuring the overall structural stability of the fixing frame.
[0059] In terms of the position of the fastening screw 11, they play a crucial limiting role. After the screw 11 is adjusted to a suitable position to achieve an ideal fixing effect on the infusion site, the fastening of the first positioning screw cap 13 and the second positioning screw cap 14 can prevent the screw 11 from undergoing unnecessary displacement.
[0060] As Figure 3 shown, in some embodiments, the two cover plates 15 are set at different heights and are on the same horizontal installation plane; firstly, the different set heights can better adapt to the shape and contour of the infusion site. For example, for parts such as the arm, there may be uneven thickness, and the cover plates 15 with different heights can contact the skin at different positions respectively, so as to provide more uniform and stable pressure and enhance the fixing effect.
[0061] Secondly, being on the same horizontal installation plane ensures that the two cover plates 15 can work together and jointly play a fixing role. Even though the contact points of them are at different heights, as a whole, they can form a unified fixing plane, avoiding uneven force or local insecure fixing.
[0062] Furthermore, this design is beneficial to dispersing pressure. When fixing the infusion site, the cover plates 15 with different heights can disperse the pressure to different areas, reducing the damage caused by excessive single-point pressure to the skin and blood vessels.
[0063] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
