[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0041] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a restraint device for assisting infusion. The restraint device includes a detachably connected base 100 and a restraint part 200. The base 100 includes a fixing groove 110 and a fixing strap 120. The fixing strap 120 is fixedly connected to the base 100 and serves to fix the fixing groove 110 to a preset position (such as an infusion chair, hospital bed, or infusion stand). The restraint part 200 is detachably connected to the fixing groove 110 via a buckle 220. The restraint part 200 is provided with a clamping mechanism to restrain the patient's wrist.

[0042] When using the restraint device disclosed in this utility model, the restraint part 200 can be first fixed to the patient's wrist or other location (taking the wrist as an example). Then, the restraint part 200 is fixed to the base 100. Since the base 100 and the restraint part 200 are connected by a snap fastener 220, they can be quickly connected and disconnected, and the restraint part 200 can be quickly fixed to the base 100. Before the patient undergoes puncture, the base 100 and the restraint part 200 can be connected and installed in a preset position, and then the patient's wrist is restrained to the restraint part 200.

[0043] When the base 100 is fixed to a preset position, it is secured to that position via the restraint part 200, such as the armrest of a chair in an infusion hall, the edge of a hospital bed, or an infusion stand. The base 100 and the restraint part 200 are detachably connected, which avoids difficulties in restraining a patient who is uncooperative. For example, when using only a strap for restraint, it is difficult for a medical staff member to complete the restraint alone if the patient is uncooperative. With this application, the restraint part 200 can be first secured to the patient's wrist using a clamping mechanism, and then fixed to the base 100. Furthermore, if either the base 100 or the restraint part 200 is damaged, they can be replaced separately.

[0044] The infusion patient restraint device disclosed in this embodiment of the utility model is provided with a base 100 and a restraint part 200. The base 100 and the restraint part 200 are detachably connected by a buckle 220. The base 100 is fixed by a fixing strap 120, so that the restraint device can be fixed to a chair, hospital bed, or infusion stand, realizing the universality of the restraint device in infusion halls and wards. The detachability between the base 100 and the restraint part 200 allows the base 100 and the restraint part 200 to be replaced separately, reducing the cost of use.

[0045] Specifically, in this embodiment, such as Figure 2 As shown, the fixing groove 110 is a circular groove structure. A limiting ring 111 is provided at the opening of the fixing groove 110. The limiting ring 111 has a chamfered structure on the side near the opening. When the base 100 and the binding part 200 are connected, the buckle 220 is locked in the limiting ring 111.

[0046] The fixing strap 120 can be a Velcro strap or a buckle strap. In this embodiment, the fixing strap 120 is a Velcro strap. The fixing groove 110 is provided with two symmetrically arranged strip holes for the fixing strap 120 to pass through. One end of the fixing strap 120 is sewn into one of the strip holes, and the other end of the fixing strap 120 passes through the other strip hole.

[0047] As a preferred embodiment of this invention, the side of the fixing groove 110 where the fixing strap 120 is installed is also provided with an arc groove structure to adapt to different installation positions, such as the support rod on the infusion stand, the chair handle with a circular surface, etc.

[0048] The restraint part 200 also includes a housing 210, and the clamping mechanism and the fastener 220 are both disposed on the housing 210. Figure 2 , Figure 6 as well as Figure 7 As shown, the housing 210 includes a bottom shell 211 and a cover plate 212. The bottom shell 211 is a stepped cylindrical structure with one end larger than the other. When the smaller end of the bottom shell 211 is connected to the binding part 200 and the base 100, it is fitted inside the fixing groove 110. The cover plate 212 and the bottom shell 211 are fixedly connected by screws. A space for installing the buckle 220 and the clamping structure is formed between the bottom shell 211 and the cover plate 212. The bottom shell 211 is a cylindrical shape with an opening at one end. The inner diameter of the smaller end of the bottom shell 211 is the same as the inner diameter of the limiting ring 111.

[0049] As a preferred embodiment of this example, Figures 2 to 4 as well as Figure 7As shown, the latching component 220 includes a fixing buckle 221 and a return spring 222. The fixing buckle 221 is provided with an integrally connected locking tongue and a pressing block. The locking tongue and the pressing block are connected by a connecting plate. Both the locking tongue and the pressing block are located inside the bottom shell 211 and pass through the cylindrical wall of the bottom shell 211. The locking tongue is located at the smaller inner diameter section of the bottom shell 211, and the pressing block is located at the larger inner diameter section of the bottom shell 211. A baffle 213 is provided on the bottom shell 211. The two ends of the return spring 222 abut against the... When the binding part 200 is installed at the baffle 213 and the connecting plate, the locking tongue moves inward to the inside of the bottom shell 211 under the pressure of the limiting ring 111, and the return spring 222 is compressed. When the bottom shell 211 enters the fixing groove 110, the locking tongue extends out under the action of the return spring 222 and is locked at the limiting ring 111. Two sets of buckle members 220 are provided, and the return spring 222 is symmetrically arranged about the center of the bottom shell 211.

[0050] As a preferred embodiment of this invention, the clamping structure includes:

[0051] Two symmetrically arranged restraint plates 230 are located on the housing 210;

[0052] Restraint airbag 240, each of the restraint plates 230 is provided with a restraint airbag 240, the restraint airbag 240 is located on the opposite side of the restraint plate 230;

[0053] Air pump 260 is used to inflate the restraint airbag 240;

[0054] A control valve 270 is provided on the pipeline between the restraint airbag 240 and the air pump 260, and is used to maintain the pressure of the restraint airbag 240.

[0055] Specifically, in this embodiment, the restraint plate 230 is a plate-shaped structure, one end of which is connected to the cover plate 212. The airbag is square, and one side of the restraint airbag 240 is glued to the restraint plate 230. The air pump 260 is fixedly connected to the inside of the housing 210 by screws and is connected to the inflation port of the restraint airbag 240 via a hose. The control valve 270 is a three-way solenoid valve that stops inflating after a preset time. When the control valve 270 closes the inflation port of the restraint airbag 240, the air pump 260 and the control valve 270 are implemented by a control mechanism, which is a single-chip microcomputer or microprocessor. The control mechanism is electrically connected to the air pump 260 and the control valve 270 through wires. The control mechanism is also connected to a battery, which is a rechargeable lithium battery. The control mechanism is also connected to a charging and discharging structure for supplying power to the battery. The battery is electrically connected to the control valve 270 and the air pump 260.

[0056] Preferably, a pressure sensor is also provided inside the restraint airbag 240. The pressure sensor is electrically connected to the control mechanism. The pressure sensor is used to detect the pressure inside the restraint airbag 240. When the pressure inside the restraint airbag 240 reaches a preset value, the control mechanism stops the inflation of the restraint airbag 240. The control mechanism is also provided with a control panel (such as buttons) on the housing 210. The control panel is provided with control buttons for sending inflation and deflation commands to the control mechanism respectively.

[0057] As a preferred embodiment of this example, Figure 2 , Figures 5 to 8As shown, the restraint plate 230 is hinged to the housing 210.

The restraint airbag 240 includes a wrist airbag 241 attached to the restraint plate 230 and a clamping airbag 242 located within the limiting groove 214. The wrist airbag 241 communicates with the clamping airbag 242. The end of the clamping airbag 242 is attached to the sidewalls of the restraint plate 230 and the limiting groove 214. One end of the restraint plate 230 passes through the cover plate 212 and is located at one end of the limiting groove 214. The limiting groove 214 faces away from the bottom shell 211. A plug plate 280 is also provided on one side. The limiting groove 214, the plug plate 280, and the cover plate 212 form a square box with an opening at one end. The opening of the box formed by the limiting groove 214, the plug plate 280, and the cover plate 212 is close to the restraint plate 230. The air pump 260 is connected to the clamping airbag 242. When the air pump 260 inflates, the clamping airbag 242 and the clamping airbag 242 expand simultaneously. The clamping airbag 242 lifts the restraint plate 230, causing the restraint plate 230 to rotate inward, thereby securing the wrist of the infusion patient. When the restraint airbag 240 deflates, the restraint airbag 240 contracts and opens the restraint plate 230, making it easy to remove the restraint device.

[0058] In a preferred embodiment of this invention, a pad 250 is provided between the two binding plates 230. The pad 250 is a flexible block, such as a sponge block in this embodiment. The pad 250 is fixedly connected to the cover plate 212 by adhesive.
