Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical nursing apparatus, in particular to a remaining needle fixing device. BACKGROUND

[0002] In the field of hemodialysis treatment, remaining needle plays a vital role, which provides a stable passage for blood extraction and back infusion, ensuring that the dialysis process can be carried out smoothly and continuously. However, the traditional dialysis remaining needle fixing method has many defects, which seriously affects the effect of dialysis treatment and the safety and comfort of patients, prompting the research and development of the new fixing device.

[0003] The common dialysis remaining needle fixing method in clinical practice at present is to use ordinary medical adhesive tape for sticking and fixing. This fixing method has poor stability. During the dialysis process, the patient has to maintain a relatively fixed posture for a long time, and the body will inevitably produce involuntary micro-motions, such as slight flexion and extension of the limbs, rotation, etc. These small actions can easily cause the remaining needle to shift. Once the remaining needle shifts, it may cause damage to the blood vessel wall at the puncture site, causing complications such as local bleeding and hematoma. More seriously, the remaining needle shift may also cause the needle to come out of the blood vessel, making the dialysis unable to proceed normally, and the treatment has to be interrupted and the puncture and catheterization have to be performed again. This not only brings additional pain to the patient, increases the risk of infection, but also prolongs the dialysis time and increases the workload of medical staff. CONTENT OF THE UTILITY MODEL

[0024] As Figure 1 shown, the preferred embodiment of the indwelling needle fixing device provided by the utility model, including fixed main body 1 and detachably installed on the fixed main body 1 anti- oppression mechanism 2, anti- oppression mechanism 2 including for the indwelling needle is limited and is limited frame 21 and is set up in the arc-shaped avoiding groove 22 for preventing oppression indwelling needle head of the bottom of limiting frame 21, indwelling needle fixing device still includes the buffer mechanism 3 of installation between limiting frame 21 and indwelling needle, through limiting frame 21 and bottom arc-shaped avoiding groove 22, accurate avoid indwelling needle needle head is oppressed, effectively maintain the smoothness of infusion, reduce the risk of vascular injury.

[0025] In the embodiment, the fixed main body 1 is in the form of a long strip and is made of an elastic net with certain flexibility and strength. The fixed main body 1 further includes a hook-faced magic tape 11 installed at one end and a fleece-faced magic tape 12 installed at the other end. The hook-faced magic tape 11 and the fleece-faced magic tape 12 are connected in cooperation and can be firmly attached to the surface of the patient's skin. In other embodiments, the fixed main body 1 is provided with auxiliary fixing components, such as adjustable straps or elastic buckles, to further enhance the stability of the fixing and adapt to the thickness and activity requirements of different patients' limbs.

[0026] Specifically, the limiting frame 21 is in the form of a U-shape, and the size of its opening is adapted to the diameter and length of the indwelling needle, so that it can closely fit the outer contour of the indwelling needle. The limiting frame 21 is mainly used to accurately limit the position of the indwelling needle and avoid unnecessary movement of the indwelling needle in the horizontal and vertical directions. When the patient's limb moves or is subjected to external force impact, the limiting frame 21 provides reliable physical support and protection for the indwelling needle, maintains the stability of the indwelling needle, and ensures the safety and smoothness of the infusion process.

[0027] Specifically, the arc-shaped avoiding groove 22 is located at the central position of the bottom of the limiting frame 21, and its curvature is matched with the curved shape of the needle head of the indwelling needle, so that the needle head of the indwelling needle can naturally be located in the arc-shaped avoiding groove 22 and form a certain space interval with the bottom of the limiting frame 21. When the fixing device contacts the patient's skin or other objects, the arc-shaped avoiding groove 22 can ensure that the needle head does not directly bear pressure.

[0028] Specifically, the buffer mechanism 3 is made of soft and elastic materials such as sponge pads or silica gel pads, and plays a role in buffering and shock absorption between the indwelling needle and the limiting frame 21. When the patient's limb moves or is subjected to external force impact, the buffer mechanism 3 can absorb and disperse these energies, reducing the vibration and impact force received by the indwelling needle.

[0029] In the embodiment, the fixed body 1 is arranged outside the limiting frame 21 to fix the limiting frame 21 and the indwelling needle, and an antibacterial layer is arranged between the limiting frame 21 and the fixed body 1. An antibacterial coating, such as a nano-silver antibacterial coating, is added to the surface of the limiting frame 21 and the elastic net. In this way, the growth of bacteria can be effectively inhibited, and the risk of infection at the puncture site of the indwelling needle can be reduced, which is of great significance to patients who need to have the indwelling needle for a long time.

[0030] In the embodiment, the anti-pressing mechanism 2 further comprises an alarm device 23 arranged in the arc-shaped avoiding groove for detecting the pressing of the indwelling needle head. The alarm device 23 comprises a pressure sensor and a warning light connected with the pressure sensor. The pressure sensor accurately monitors the pressure of the indwelling needle head in the arc-shaped avoiding groove 22, and once the pressure value approaches or exceeds the critical value that may cause damage to the needle head, the signal is quickly transmitted to the warning light. The warning light is immediately turned on, clearly and intuitively warning the medical staff and the patient.

[0031] In the embodiment, anti-skid textures are arranged on the limiting frame 21. The anti-skid textures are used to increase the friction of the surface of the limiting frame 21, and can effectively reduce the relative sliding caused by external force when the limiting frame 21 is in contact with the indwelling needle or the surrounding environment under the auxiliary fixation of the fixed body 1.

[0032] Another aspect of the embodiment of the application provides an indwelling needle arranged in the indwelling needle fixing device.

[0033] The indwelling needle fixing device provided by the application comprises a fixed body 1 and an anti-pressing mechanism 2 detachably arranged on the fixed body 1, the anti-pressing mechanism 2 comprises a limiting frame 21 for limiting the indwelling needle and an arc-shaped avoiding groove 22 arranged at the bottom of the limiting frame 21 for preventing the indwelling needle head from being pressed, and the indwelling needle fixing device further comprises a buffer mechanism 3 arranged between the limiting frame 21 and the indwelling needle. Through the limiting frame 21 and the arc-shaped avoiding groove 22 at the bottom, the indwelling needle head is accurately prevented from being pressed, the smooth infusion is effectively maintained, and the risk of blood vessel damage is reduced. The buffer mechanism 3 arranged between the limiting frame 21 and the indwelling needle can further absorb external impact force, reduce the shaking and displacement of the indwelling needle, greatly improve the stability and safety of the indwelling needle, provide reliable protection for the treatment process of the patient, and facilitate the observation and management of the state of the indwelling needle by the medical staff, which helps to improve the overall medical care quality and efficiency.
