Description

Technical Field

[0001] This invention relates to an infusion limiting device, and more specifically, to an infusion hand limiting device that achieves blocking based on a telescopic mechanism. Background Technology

[0002] An infusion hand restraint device is a device used to restrain the arm of pediatric patients during intravenous infusion. In the medical field, intravenous infusion is a common treatment method that delivers medications or nutritional solutions into the patient's body through an infusion tube to meet their corresponding therapeutic needs.

[0003] Existing technologies for hand-operated infusion limiting devices have some shortcomings:

[0004] Existing infusion hand restraint devices may not provide effective shielding, allowing pediatric patients to directly see the infusion needle during infusion, increasing the likelihood of them experiencing fear. Secondly, existing infusion hand restraint devices may not be able to connect to infusion tubing supports, which are prone to displacement and shaking, potentially causing the infusion tubing to detach or malfunction. Furthermore, in existing technologies, the flow rate regulating device for the infusion tubing is usually not fixed in position during use, sometimes located at the top and sometimes at the bottom, making adjustment inconvenient.

[0005] In summary, existing technologies have some shortcomings in terms of blocking, fixing, and adjustment. Therefore, there is an urgent need for a telescopic hand-held limiting device for infusion to overcome the deficiencies of existing technologies. Summary of the Invention

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example

[0048] Please see Figure 1 As shown, the purpose of this embodiment is to provide an infusion hand restraint device based on telescopic shielding, including a support plate 10 for placing the infusion arm of a pediatric patient. The support plate 10 has a mounting assembly 50 at its bottom end, and the support plate 10 is fixed to the armrest of a seat via the mounting assembly 50. One end of the support plate 10 has a restraint assembly 20, which is used to fix the infusion tube and adjust the infusion tube flow rate. To shield the puncture procedure when medical personnel insert an infusion needle into a pediatric patient, a shielding assembly 30 is provided on one side of the upper surface of the support plate 10 in this embodiment. The shielding assembly 30 and the restraint assembly 20 work together to shield the pediatric patient from the infusion needle. Furthermore, considering the need to stabilize the support for the infusion bottle, a fixing assembly 40 is movably connected to the side of the support plate 10 near the restraint assembly 20, which stabilizes the infusion bottle support.

[0049] The following is a detailed description of the infusion hand limiting device based on a telescopic design for achieving shielding.

[0050] Please see Figure 2As shown, a heating groove is provided on the upper surface of the support plate 10 near the shielding assembly 30. A heating tube 12 is installed inside the heating groove. The heating tube 12 generates heat when energized. Its main purpose is to provide appropriate heat to the hands of pediatric patients during intravenous infusion. A partition 13 is provided on the top of the heating groove. Its main purpose is to insulate the high heat generated by the heating tube 12, so that the temperature emitted when in contact with the hand is slightly higher than the human body temperature. In addition, two pressure bands 14 are provided in the middle of the upper surface of the support plate 10. One pressure band 14 is fixed to the surface of the support plate 10, and the other pressure band 14 is fixed inside the groove 15 opened on the surface of the support plate 10. By wrapping and binding the two pressure bands 14 around the patient's wrist, the local venous filling is increased, which is conducive to puncture. After the puncture is completed, one of the untied pressure bands 14 can be inserted into the groove 15 for concealment.

[0051] Please see Figure 3 As shown, in order to facilitate the stabilization of the infusion tube, the limiting assembly 20 includes at least a sliding seat 21. One end of the upper surface of the support plate 10 is provided with a baffle 11 for limiting the hand. The sliding seat 21 is fixed to one end of the baffle 11. A fixing head 22 is connected to the top of the sliding seat 21. One end of the fixing head 22 is provided with a slot 220 for inserting the infusion tube. The other end of the fixing head 22 is also provided with a sliding plate 221. The sliding plate 221 is slidably connected to the inside of the sliding seat 21. By sliding the sliding plate 221, the fixing head 22 can be extended and retracted. When performing intravenous puncture, the fixing head 22 can be extended. In addition, the top of the fixing head 22 is also provided with a clamp 222. The clamp 222 is a circular structure with several protrusions inside. When the infusion tube is inserted into the clamp 222, the protrusions squeeze the infusion tube and increase the friction to stabilize the infusion tube.

[0052] Please see Figure 4 As shown, to further stabilize the infusion tube inserted into the slot 220 and to regulate the infusion flow rate, a rotating groove 223 is provided at one end of the fixed head 22. The rotating groove 223 is rotatably connected to a limiting rod 24. By rotating the limiting rod 24, the tubing inserted into the slot 220 is squeezed. During squeezing, the tubing is not only stabilized, but the gaps in the inner wall of the tubing can also be widened and narrowed under varying squeezing pressure, thereby controlling the flow rate. Considering the need to drive the limiting rod 24 to rotate, in this embodiment, a small gear 241 is provided at the connection between one end of the limiting rod 24 and the rotating groove 223. A rotating head 25 is rotatably connected to the surface of the fixed head 22. The rotating head 25 extends into the rotating groove 223 and is provided with a large gear 251. The large gear 251 meshes with the small gear 241. By rotating the rotating head 25, the limiting rod 24 can be driven to rotate.

[0053] Please see Figure 5 and Figure 6As shown, to facilitate the concealment of the puncture, the concealment assembly 30 includes at least a side seat 31. The side seat 31 is fixed to one end of the upper surface of the support plate 10. A spring coil 311 is provided inside the side seat 31. The spring coil 311 rotates inside the side seat 31 via a shaft fixed at one end. The other end of the spring coil 311 is connected to a curtain 32. The curtain 32 extends out of the side seat 31 through an opening at the top of the side seat 31. The cooperation relationship between the side seat 31, the spring coil 311, and the curtain 32 can be referenced with a measuring tape. When the curtain 32 is pulled, the spring inside the spring coil 311 rotates and contracts, forming a rebound force. When the curtain 32 is released, the rebound force of the side seat 31 causes the curtain 32 to automatically reset, so that the curtain 32 is hidden inside the side seat 31. In addition, a rotating shaft 312 is rotatably connected to the opening at the top of the side seat 31, which is used to fit against the surface of the curtain 32 to improve the smoothness of pulling the curtain 32.

[0054] Please see Figure 7 As shown, in order to facilitate the stabilization of the pulled-out curtain 32, a connecting rod 23 is provided at one end of the fixing head 22. A fixing groove 230 is opened on the upper surface of the connecting rod 23. A stop bar 321 is fixed at the end of the curtain 32 away from the side seat 31. When the curtain 32 is pulled into the fixing groove 230, the stop bar 321 is put into contact with the side surface of the connecting rod 23 away from the side seat 31, so that the stop bar 321 has a limiting function, thereby fixing the curtain 32 after it is unfolded.

[0055] Please see Figure 8-10 As shown, considering the need to stabilize the infusion bottle support, the fixing assembly 40 includes at least a first arc head 41 and a second arc head 42. The first arc head 41 and the second arc head 42 are rotatably connected. After the first arc head 41 and the second arc head 42 are rotated until their ends fit together, they form a ring structure for fitting the infusion tube support. The support plate 10 has a movable groove 16 inside. One end of the first arc head 41 is provided with a rotating rod 43. One end of the rotating rod 43 is rotatably connected inside the movable groove 16. When the rotating rod 43 rotates, it can move in the movable groove 16, which facilitates changing the orientation of the first arc head 41 and the second arc head 42. Before changing the orientation of the fixing assembly 40, please refer to [reference needed]. Figure 11As shown; furthermore, a slider 44 is slidably connected inside the rotating rod 43, and a plug 441 is provided at one end of the slider 44. A sliding opening 431 is provided on the upper surface of the rotating rod 43. When the slider 44 slides, it can drive the plug 441 to slide inside the sliding opening 431. A slot 110 is provided on the side of the retaining edge 11 near the fixing assembly 40. The internal shape of the slot 110 is adapted to the plug 441. When the plug 441 slides, it can enter into the slot 110, thereby stabilizing the fixing assembly 40. Furthermore, a fitting head 442 is connected to the end of the slider 44 away from the plug 441. The fitting head 442 is connected to the slider 44 through a crossbar. The crossbar slides with the first arc-shaped head 41. Therefore, when the fitting head 442 slides, the plug 441 can slide into the plug 441. When the head 442 is displaced, it can drive the slider 44 to move. Specifically, when the infusion tube support enters the first arc head 41 and the second arc head 42, the support can press against the head 442, thereby pushing the slider 44. In order to stabilize the connection between the first arc head 41 and the second arc head 42, one end of the first arc head 41 and the second arc head 42 are fixedly connected by bolts. In addition, a sliding rod 432 is provided at the end of the rotating rod 43 away from the slider 44. The sliding rod 432 is slidably connected to the slider 44, and a spring 433 is sleeved on the surface of the sliding rod 432. One end of the spring 433 is fixedly connected to the slider 44. Its main purpose is to facilitate the slider 44 to return to its original position.

[0056] Please see Figure 12 As shown, considering the need to install the support plate 10, the installation assembly 50 includes at least a bonding plate 51. The lower surface of the bonding plate 51 has an arc-shaped structure, the main purpose of which is to facilitate the fitting of the seat handle. The bottom of the bonding plate 51 is provided with several Velcro straps 52, each of which includes a rough side and a hook side, which can be glued together. When the support plate 10 needs to be installed, simply attach the bonding plate 51 to the upper surface of the handle, and then pass the hook side and rough side of the Velcro strap 52 through the bottom of the handle and glue them tightly.

[0057] In summary, the embodiments of the present invention also provide a method for using a telescopic hand-operated blocking device for infusion, as detailed below:

[0058] S1. First, install the support plate 10 above the handle using the mounting assembly 50. Taking the direction shown in the attached figure as an example, the support plate 10 is installed on the right handle. Then, connect the heating tube 12 to the power supply to generate heat.

[0059] S2. Place the patient's palm on the partition 13, with the arm against the support plate 10. Then, tie two pressure bands 14 around the patient's elbow to increase local venous filling. Next, pull the fixing head 22 to extend, and then pull the curtain 32 to extend and connect with the connecting rod 23 to form a shield. After this, the medical staff will perform the puncture.

[0060] S3. After the puncture is completed, insert the infusion tube into the jack 222 and the jack slot 220, and then rotate the rotating head 25 to drive the limiting rod 24 to squeeze the infusion tube, stabilize it and adjust the flow rate.

[0061] S4. Manually rotate the fixing group 40 perpendicular to the stop 11, then insert the infusion tube support between the first arc head 41 and the second arc head 42, and fix the first arc head 41 and the second arc head 42 with bolts. At this time, the plug 441 enters the slot 110 to fix the fixing group 40, and also to fix the infusion tube support.

[0062] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
