Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a novel mental nursing infusion fixing device. BACKGROUND

[0002] In clinical nursing in psychiatry, when intravenous infusion is performed on patients with mental symptoms, consciousness disorders or restlessness, such patients may have unconscious limb movements, attempt to remove the needle tube or excessively pull the infusion pipeline due to disease, which can easily lead to needle slippage, puncture site bleeding, local swelling and even phlebitis and other complications, not only affecting the treatment effect and increasing the patient's pain, but also increasing the workload of medical staff.

[0003] In the prior art, traditional restraint belts or ordinary fixing plates are often used in clinical practice to fix the limbs of patients. However, the traditional restraint belt can only achieve simple encircling and binding of the wrist or forearm, and the fixing method is relatively single, which is difficult to effectively limit the fine movement of the fingers, and the patient can still touch the puncture site or infusion connector through the grasping and picking actions of the fingers. In addition, although the hard fixing plate can provide good support, it often completely limits the movement of the wrist joint, and long-term fixation can easily cause joint stiffness and discomfort in patients, and is not conducive to real-time observation of the puncture site and orderly management of the pipeline.

[0022] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0023] The embodiment of the present application provides a new type of psychiatric nursing infusion fixing device, which can be referred to Figures 1-2 , comprising an arm fixing mechanism 1, a hand fixing mechanism 2, a connecting piece 3, a fixing unit, a pipe arranging mechanism 6 and a pipe buffering mechanism 7. The arm fixing mechanism 1 is used for surrounding and fixing the arm of a patient; the hand fixing mechanism 2 is arranged at the front end of the arm fixing mechanism 1 and has a finger fixing sleeve 21 matched with the fingers of the patient, and is used for positioning and fixing the hand; the connecting piece 3 is connected between the arm fixing mechanism 1 and the hand fixing mechanism 2, and allows the hand to move relative to the arm within a preset range. The fixing unit has an observation mechanism 4 located on the hand fixing mechanism 2, and has a connecting head fixing mechanism 5 located at the observation mechanism 4, and the fixing unit is used for observation of infusion backflow and detachable fixing of a needle tail connecting head; the pipe arranging mechanism 6 is arranged on one side of the arm fixing mechanism 1, and is used for arranging and fixing the infusion pipe along the arm direction; the pipe buffering mechanism 7 is arranged at one end of the pipe arranging mechanism 6, and is used for elastically buffering the pulling of the infusion pipe when the hand moves.

[0024] The arm of the patient is fixed by the arm fixing mechanism 1, the hand is positioned and fixed by the finger fixing sleeve 21 of the hand fixing mechanism 2, the fine movement of the fingers is effectively limited, unplanned extubation and needle displacement are prevented, the hand is allowed to move within a preset range by the connecting piece 3, the comfort of the patient is improved and joint stiffness is reduced, the observation mechanism 4 and the connecting head fixing mechanism 5 are integrated in the fixing unit, the puncture point is observed in real time and the infusion connecting head is reliably fixed, the pipe arranging mechanism 6 arranges the infusion pipe in an orderly manner, and the risk of hooking is reduced, the pipe buffering mechanism 7 absorbs the pulling force through elastic buffering, and needle slipping and puncture point injury are further prevented, so that the safety and effectiveness of psychiatric patient infusion nursing are improved as a whole.

[0025] As one embodiment of the present embodiment, the new type of psychiatric nursing infusion fixing device can be referred to Figure 2The arm fixation mechanism 1 includes a fixation cover 11, a first restraint strap 12, and a first buckle 13. The fixation cover 11 has an arc-shaped cross-section that conforms to the contour of the arm, used to support and cover the arm area. Specifically, the fixation cover 11 provides structural support, providing a rigid or semi-rigid frame to support the back and sides of the arm, wrapping the arm within its arc surface. This avoids poor blood flow or skin pressure injuries caused by excessive local pressure, improving comfort and safety. Simultaneously, its arc-shaped structure better conforms to the physiological curve of the arm, enhancing fixation stability.

[0026] Multiple first restraint straps 12 are provided and evenly arranged along the extension direction of the fixing cover 11 to achieve segmented fixation of different parts of the forearm; one end of each first restraint strap 12 is fixedly connected to the side of the fixing cover 11, and the other end is provided with a hook and loop face of Velcro for forming a wrap-around fixation; multiple first buckles 13 are provided and fixedly installed on the fixing cover 11, and are respectively arranged in a one-to-one correspondence with the first restraint straps 12 for the corresponding first restraint straps 12 to pass through and lock their tightness; the first buckles 13 provide a channel for the free end of the first restraint straps 12 to pass through and guide, ensuring that the first restraint straps 12 can wrap around the arm in the correct position and angle.

[0027] The first restraint strap 12 and the first buckle 13 together constitute an adjustable restraint structure. The first buckle 13 is used to guide and fix the first restraint strap 12. The Velcro on the first restraint strap 12 can be quickly attached and the tightness can be adjusted, ultimately reliably fixing the patient's arm inside the fixation cover 11.

[0028] In practice, the patient's arm is placed within the arc-shaped structure of the fixation cover 11. The contour of the fixation cover 11 conforms to the arm, providing initial positioning and stable support. The operator pulls the free ends of each of the first restraint straps 12 in sequence, causing them to wrap around the arm. The free ends of the first restraint straps 12 pass through the corresponding first buckles 13, ensuring the correct direction of action. After tightening the first restraint straps 12 to a suitable tightness, the hook and loop sides of the Velcro are pressed together to complete the fixation of that restraint point.

[0029] As one implementation method of this embodiment, please refer to Figures 2-3 The hand fixation mechanism 2 includes a hand cover 22, a finger fixation sleeve 21, a second restraint strap 23, and a second buckle 24. The hand cover 22 is a hollow plate-like structure adapted to the contour of the back of the hand, with an opening at the bottom for the palm to enter. The hand cover 22 serves as the main frame of the hand fixation mechanism 2, covering the back of the hand to form a protective layer, preventing the patient from directly touching the puncture site or infusion connector. Simultaneously, it serves as the mounting base for other components, ensuring the integrity of the structure and the synergy of its functions. In use, the shape of the hand cover 22, adapted to the contour of the back of the hand, can restrain the hand in the correct position.

[0030] The plurality of finger fixing sleeves 21 are arranged inside the hand cover 22 and are independent and have elastic finger sleeve structures, which are matched with the thumb, index finger and middle finger, ring finger and little finger respectively; during use, each finger is wrapped by an independent finger fixing sleeve 21 to realize individual fixing. The dangerous actions of grabbing, picking and pinching of a single finger of the patient can be effectively prevented, and the pulling of the back of the hand muscles and skin and the displacement of the needle can be avoided. At the same time, the finger fixing sleeve 21 is made of elastic material and can adapt to fingers of different thicknesses and avoid excessive compression to ensure smooth blood flow. The movement range of the fingers is limited within the slight deformation range of the finger fixing sleeve 21 itself, rather than being completely rigid, and a balance between safety and comfort is achieved. Moreover, in cooperation with the hand cover 22, the pulling force from the fingers can be dispersed to the entire back of the hand area.

[0031] The plurality of second binding belts 23 are arranged along the extension direction of the hand cover 22, one end of each second binding belt 23 is fixedly connected with the hand cover 22, and the other end is provided with a hook face and a hair face of a magic tape to form a fixing around the hand; the second binding belt 23 is arranged around the wrist and palm and cooperates with the hand cover 22 to realize the ring-shaped fixing of the hand and prevent the hand from rotating or being pulled out as a whole from the hand cover 22. The plurality of second buckles 24 are fixedly installed on the hand cover 22 and are arranged one by one corresponding to the second binding belts 23, for allowing the corresponding second binding belts 23 to pass through and lock the tightness. The second buckle 24 serves as a channel for the second binding belt 23 to pass through, ensures that the second buckle 24 exerts force at a correct angle, and cooperates with the magic tape to realize the adjustment of the tightness and prevent loosening during use.

[0032] In specific implementation, the patient inserts the palm from the opening at the bottom of the hand cover 22 and makes the back of the hand adhere to the inner cavity of the hand cover 22. At this time, the fingers are naturally placed in the corresponding finger fixing sleeves 21. At this time, the five independent elastic finger fixing sleeves 21 wrap each finger to limit the independent movement ability of the fingers. The operator tightens each second binding belt 23 to make it wrap around the wrist and palm. After the second binding belt 23 passes through the second buckle 24, the tightness is adjusted and fixed by the magic tape.

[0033] As an embodiment of the present embodiment, reference can be made to Figures 1-2 The connecting member 3 is an integral belt-shaped member made of flexible material, and the two ends thereof are fixedly connected with the arm fixing mechanism 1 and the hand fixing mechanism 2 respectively; the length of the connecting member 3 is configured to allow the patient to flex and / or laterally move the hand within the flexible deformation range of the connecting member 3; wherein the flexible material is medical-grade silicone or thermoplastic polyurethane elastomer.

[0034] In the specific implementation, when the patient's hand is relaxed, the connecting member 3 is in a natural undeformed state. At this time, the hand is maintained in a preset neutral position relative to the arm; when the patient tries to move the wrist, the fixing mechanism 2 of the hand is subjected to force, and the force is transmitted to the connecting member 3 itself through the connecting point of the connecting member 3 and the hand cover 22. The connecting member 3 begins to elastically bend, stretch or torsionally deform under the action of the force. As the amplitude of the movement increases, the deformation of the connecting member 3 also increases, and the restoring force generated by the connecting member 3 will be greater, providing the patient with a gradually increasing resistance feeling; when the movement reaches the limit of the preset range determined by the length and material properties of the connecting member 3, the deformation and restoring force of the connecting member 3 will prevent further movement of the hand; when the patient stops moving and the external force is removed, the elastic potential energy stored in the material of the connecting member 3 is released, driving the connecting member 3 to restore to the original shape and length, thereby naturally pulling the hand back and stabilizing it in the neutral initial position.

[0035] As an embodiment of the present embodiment, reference can be made to Figure 3 and Figures 5-6 The observation mechanism 4 includes an observation window 41, a transparent cover 42, a first magnet 43 and a second magnet 44. Among them, The observation window 41 is a through hole opened on the hand cover 22, providing a direct visual channel for medical personnel, so that they can directly observe the condition of the patient's hand vein puncture point without removing the overall fixation of the hand, including whether there are key clinical signs such as backflow, swelling, exudation, skin redness, etc.

[0036] The observation window 41 is positioned corresponding to the needle eye area after the patient's hand vein is punctured, ensuring that the target area can be accurately observed through the observation window 41 at any time, avoiding blind search.

[0037] The transparent cover 42 is rotatably connected with the side of the observation window 41, so that the transparent cover 42 has a closed position covering the observation window 41 and an open position away from the observation window 41. When in the closed position, the transparent cover 42 covers the observation window 41, forming a physical barrier to prevent external contaminants (such as dust, microorganisms) from contacting the puncture point through the observation window 41, and also preventing the patient from accidentally touching the needle eye area. When in the open position, an operation channel to the puncture point is provided, facilitating medical personnel to perform necessary emergency treatment such as disinfection or wiping.

[0038] The first magnet 43 is embedded on the transparent cover 42; the second magnet 44 is correspondingly embedded on the edge of the observation window 41 of the hand cover 22; wherein when the transparent cover 42 is in the closed position, the first magnet 43 and the second magnet 44 are attracted to each other to keep the transparent cover 42 in a tightly closed state.

[0039] In the specific implementation, the transparent cover 42 is reliably adsorbed and fixed by the magnetic force of the first magnet 43 and the second magnet 44 during the infusion time. At this time, the transparent cover 42 isolates the external environment, and the medical staff can observe the exposed puncture point below through the observation window 41 at any time. When careful examination or treatment is needed, the medical staff only needs to exert a pulling force on the transparent cover 42 with a finger to overcome the adsorption force of the magnet, so as to open the transparent cover 42. At this time, the observation window 41 is completely exposed, which facilitates detailed observation or emergency operation.

[0040] After the operation is completed, when the transparent cover 42 approaches the closed position on the observation window 41, the magnetic force between the first magnet 43 and the second magnet 44 actively guides and finally adsorbs it in place, providing a clear adsorption feeling, at which time it has been reliably closed.

[0041] As an embodiment of the present embodiment, reference can be made to Figure 6 The connector fixing mechanism 5 includes a base 51, a mounting groove 52, and a cover plate 53. The base 51 is fixedly arranged on the hand cover 22 and located at one end of the observation window 41 close to the arm fixing mechanism 1, and is connected with the edge of the observation window 41. The base 51 provides a stable base for the mounting groove 52, so as to ensure that the connector fixing mechanism 5 will not be deformed or loose when the connector is placed in the mounting groove 52 or is slightly pulled, thereby ensuring the reliability thereof.

[0042] The mounting groove 52 is a U-shaped channel formed in the interior of the base 51 and is in communication with the observation window 41, allowing the connector to be vertically placed or taken out from above, which is convenient to operate. The groove wall of the mounting groove 52 is adapted to the profile of the infusion needle tail connector, and is used for accommodating and clamping the connector. The groove wall of the mounting groove 52 is adapted to the profile of the connector, which plays a wrapping and clamping role, limits the left and right shaking and rotation of the connector in the mounting groove 52, and realizes the preliminary reliable positioning and fixing. The cover plate 53 is fixedly connected with the transparent cover 42, so that the cover plate 53 can be synchronously flipped with the transparent cover 42. When the transparent cover 42 is in the closed position, the cover plate 53 covers and closes the upper opening of the mounting groove 52. When the transparent cover 42 is in the closed position, the cover plate 53 covers and closes the upper opening of the mounting groove 52, which can prevent the connector from accidentally falling out of the opening of the mounting groove 52, and at the same time, avoid the possibility of the patient (especially the psychiatric patient) scratching or touching the connector with a finger.

[0043] As an embodiment of the present embodiment, reference can be made to Figure 3The tubing mechanism 6 includes a tubing groove 61 and an elastic buckle 62. The tubing groove 61 is arranged along the length of the outer wall of the fixing cover 11 and is used to accommodate and guide the direction of the infusion tube. The tubing groove 61 restricts the originally unfixed infusion tube to a specific path, extending from near the elbow to near the wrist, making the tube layout neat. At the same time, the side walls and bottom of the tubing groove 61 provide a semi-enclosed protective structure for the infusion tube, effectively reducing the risk of the tube being accidentally caught or squeezed by external objects (such as bed rails or the patient's other hand).

[0044] Multiple elastic buckles 62 are provided and are evenly arranged along the extension direction of the tubing groove 61, which can detachably lock the infusion tube in the tubing groove 61. At the same time, the multiple evenly distributed elastic buckles 62 work together to ensure that the infusion tube fits tightly with the elastic buckles 62 along the length of the tubing groove 61, and prevent the infusion tube from sliding, arching or twisting in the tubing groove 61 due to gravity or patient movement.

[0045] The elastic buckle 62 can be elastically deformed under external force to allow the infusion tube to be inserted or removed, and will return to its original shape when there is no external force and keep the infusion tube in the tube tray 61.

[0046] In practice, after puncture and fixation, medical staff press the IV tubing into the tubing groove 61, starting near the wrist. Then, the IV tubing is inserted sequentially into the tubing groove 61 along the arm, pressing the tubing past the opening of each elastic clip 62 as it passes, securing it into the tubing groove 61. At this point, the IV tubing is completely contained within the continuous channel of the tubing groove 61 and segmentally secured by the elastic clips 62.

[0047] As one implementation method of this embodiment, please refer to Figures 3-4 The pipeline buffer mechanism 7 includes a slide groove 71, a sliding latch 72, and a thrust spring 73. Among these, The slide groove 71 is located at one end of the tube groove 61 near the hand fixing mechanism 2, providing a direction for the movement of the sliding buckle 72, so that it can only perform linear reciprocating motion along a preset axis.

[0048] The sliding buckle 72 is slidably disposed in the slide groove 71; the thrust spring 73 is disposed in the slide groove 71, with one end fixedly connected to the end of the slide groove 71 and the other end fixedly connected to the sliding buckle 72. When the infusion tubing is subjected to a pulling force toward the hand-fixing mechanism 2, the sliding buckle 72 can compress the thrust spring 73 and slide along the slide groove 71, thereby providing a buffer stroke; when the pulling force is released, the thrust spring 73 pushes the sliding buckle 72 to reset. In the specific implementation, when there is no pulling force, the pushing spring 73 is in a natural state, keeping the sliding buckle 72 in an initial position away from the hand fixing mechanism 2 in the sliding groove 71. The infusion tube is normally fixed in the sliding buckle 72. When the patient's hand moves or external factors cause the infusion tube to be pulled towards the hand, the pulling force acts on the sliding buckle 72 through the tube. The sliding buckle 72 is pulled and starts to slide along the sliding groove 71 towards the hand.

[0049] In this process, the pushing spring 73 is continuously compressed, generating a restoring force in the opposite direction, which is proportional to the amount of compression. When the pulling force decreases or disappears (for example, the patient's arm returns or the hand is released), and is less than the spring restoring force, the pushing spring 73 starts to push the sliding buckle 72 back to the initial position along the sliding groove 71.

[0050] In the specific implementation of the present application: 1) Fixing and positioning: First, the patient's arm is placed in the fixing cover 11 of the arm fixing mechanism 1. The arc-shaped structure of the fixing cover 11 is adapted to the contour of the arm, supporting and covering the back and sides of the arm, providing preliminary support. Then, the operator pulls the first restraint belts 12 one by one, making them wrap around the arm and pass through the corresponding first buckles 13, adjusting the tightness with Velcro, achieving segmented fixing, ensuring that the arm is stably restricted in the fixing cover 11, avoiding excessive local pressure, while allowing fine adjustment to adapt to different arm circumferences. Then the patient inserts the palm from the bottom opening of the hand cover 22 of the hand fixing mechanism 2, with the back of the hand fitting into the inner cavity of the hand cover 22. The five independent finger fixing sleeves 21 wrap around the thumb, index finger, middle finger, ring finger and little finger, respectively, restricting the independent movement of the fingers and preventing dangerous actions such as grabbing and picking. The second restraint belt 23 wraps around the wrist and palm, passes through the second buckle 24 and is fixed with Velcro, achieving a ring-shaped fixation to prevent the hand from rotating or escaping.

[0051] 2) Hand movement and buffering: When the patient's hand is relaxed, the connecting piece 3 is in a natural state, maintaining the neutral position of the hand. When the hand is flexed or laterally moved, the connecting piece 3 elastically deforms (such as bending, stretching or twisting), providing gradually increasing restoring force to limit the movement range within the preset range. After the external force is removed, the elastic potential energy of the connecting piece 3 drives the hand back to the initial position, ensuring safety and improving comfort.

[0052] 3) Infusion observation and connector fixation: The observation window 41 of the observation mechanism 4 is located on the hand cover 22 and corresponds to the dorsal vein puncture point. The transparent cover 42 covers the observation window 41 through a rotating connection and is fixed by the first magnet 43 and the second magnet 44 to form a closed barrier. Medical staff can directly observe the puncture point condition (such as backflow of blood and swelling) through the transparent cover 42 without disassembling the fixator. When it needs to be handled, the transparent cover 42 is pulled open to expose the puncture point, and the magnets are automatically attracted and closed after operation.

[0053] The base 51 of the connector fixing mechanism 5 is located near the observation window 41, and the installation groove 52 is a U-shaped channel for clamping and fixing the infusion needle tail connector. When the transparent cover 42 is closed, the cover plate 53 fixedly connected covers the opening above the installation groove 52 to prevent the connector from accidentally falling out or being touched by the patient. The connector can be vertically put in or taken out from above, which is convenient for operation.

[0054] 4) Infusion tube management and buffering: The tubing groove 61 of the tubing mechanism 6 is arranged along the outer wall of the fixed cover 11 for accommodating and guiding the infusion tube. A plurality of elastic buckles 62 are uniformly distributed along the tubing groove 61, which are clamped into the groove by elastic deformation to realize segmented fixing, so that the infusion tube is neatly arranged and the risk of being hooked or squeezed is reduced.

[0055] The pipeline buffering mechanism 7 is located at one end of the tubing groove 61 close to the hand fixing mechanism 2. When the infusion tube is subjected to a pulling force (such as hand movement), the sliding buckle 72 slides in the sliding groove 71 to compress the push spring 73, providing a buffering stroke; after the pulling force is eliminated, the push spring 73 pushes the sliding buckle 72 to reset, effectively absorbing the pulling energy and preventing the needle from moving or the pipeline from falling off.

[0056] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
