Description

Technical Field

[0001] The present invention relates to the technical field of outdoor auxiliary infusion equipment, and in particular to an outdoor nighttime auxiliary infusion device. Background Art

[0002] During military training in the wild, it is difficult for users to perform infusion operations on themselves in a dark environment because they cannot see the blood vessels in their hands clearly. Therefore, there is a need for an auxiliary infusion device that can assist users in performing infusion operations on their hands in a dark environment.

[0003] The publication number is CN212699921U. A multifunctional infusion auxiliary lamp comprises a lamp body bracket, a lamp head mounted on the lamp body bracket, and a pressure hemostatic cuff; the characteristic is that the lamp body bracket is fixed on the pressure hemostatic cuff, and the pressure hemostatic cuff is integrated with a wrist sphygmomanometer; the lamp head comprises a puncture lighting lamp and a blood vessel perspective lamp. The utility model is provided with an infusion lighting device, and the infusion lighting button can be pressed before the infusion is prepared to meet the infusion operation needs at night and in poor light conditions.

[0004] However, the application has the following problems in actual use. First, when performing an infusion, the hand that needs the infusion needs to maintain a very stable state during the injection, and keep it horizontal to avoid shaking as much as possible to avoid affecting the accuracy of the needle. However, in extreme outdoor environments, it may not be possible to find a platform to support the hand steadily, and the hand and elbow may need to be suspended in the air for infusion. The hand is very likely to shake, which affects the process of the needle. Second, when the user gives himself an injection, there will be a certain difference in the accuracy of the dominant hand and the non-dominant hand when operating the infusion needle. The dominant hand will be more stable and accurate when performing the injection. If it is necessary to perform the injection on the dominant hand and the non-dominant hand must be used, the blood vessel position cannot be accurately found due to problems such as hand shaking. There is a lack of an auxiliary infusion device that can ensure stable support for the horizontal placement of the hand during infusion in extreme outdoor environments, and when the non-dominant hand is used for the injection, the infusion needle can be more accurately controlled to move to the blood vessel position to be infused to improve the accuracy of the infusion needle.

[0013] Furthermore, a bendable metal tube for connection is provided between the blood vessel fluoroscopic lamp and the lighting lamp and the protective arm.

[0014] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0015] Firstly, when using the device, the user first puts the arm guard on the arm that needs infusion, and ensures that the arm guard is stably mounted on the user's arm by adjusting the Velcro on the arm guard. The arm guard is provided with an auxiliary positioning infusion device at one end close to the user's hand. The vascular perspective light and the lighting lamp can provide lighting effects for the user in a dark environment at night, and ensure that the user can clearly see the position of the blood vessels in the hand at night. The user's hand that needs infusion is placed horizontally, and the support device is unfolded and supported vertically on the ground to provide stable support force for the horizontal placement of the hand, so as to ensure accurate needle insertion, and the infusion needle is placed By controlling the auxiliary positioning infusion device, the infusion needle can be driven to move accurately to the blood vessel position on the hand where the infusion is to be inserted, and the position is relatively close to the blood vessel. The user only needs to insert the infusion needle into the blood vessel, thereby avoiding the problem that the user cannot accurately control the infusion needle to move to the blood vessel position for insertion due to hand shaking and other reasons; this device can ensure stable support for the horizontal placement of the hand when infusing in extreme outdoor environments, and when the injection operation is performed with the non-dominant hand, the infusion needle can also be more accurately controlled to move to the blood vessel position to be infused, so as to improve the accuracy of the infusion injection.

[0016] Secondly, when the user's arm is placed horizontally, in order to provide a stable supporting force for the horizontal placement of the user's arm, the support sleeve in a horizontal state is first rotated downward 90 degrees to a vertical state, and then the locking cylinder is rotated. Since the locking cylinder and the locking sleeve are eccentrically arranged, in the process of rotating the locking cylinder, the locking cylinder gradually moves away from the locking block, and the first spring contracts, thereby controlling the locking block to move away from the locking groove on the support block, thereby releasing the position lock of the support block in the support sleeve, and then the support block is slid downward and pulled out to contact the ground, and then the locking cylinder is rotated in the opposite direction to lock the position of the support block in the support sleeve, thereby achieving a supporting effect on the user's arm, ensuring that the user's arm will not be suspended in the air during infusion, and the infusion will be more stable.

[0017] Thirdly, when the support sleeve and the support block are arranged horizontally, the first rotating rod is rotated to control the first fixed block to press against the bottom of the support block, thereby ensuring that the support block remains in a horizontal state. When the support block and the support sleeve need to be adjusted to a vertical state to support the user's infusion, the first fixed block is rotated to be parallel to the first fixed hole. When the support sleeve is flipped downward, the support block will pass through the first fixed block, and the second fixed hole on the fixing frame will pass through the second fixed block. Then the second fixed block is rotated to press against the bottom of the fixing frame, thereby locking the vertical state of the support block and the support sleeve, further improving the stability of the support effect for the user's infusion arm.

[0018] Fourthly, when the user needs to control the infusion needle to move to a position close to the blood vessel of the hand for infusion, the distance between the infusion needle and the blood vessel can be adjusted by moving the guard arm, and the first screw rod is driven to rotate by manually turning the adjusting knob, thereby driving the slide rod to slide and driving the driving block to slide horizontally on the slide rod, and manually turning another adjusting knob can drive the second screw rod to rotate, thereby driving the sliding rod to slide on the second screw rod, thereby driving the driving block to slide longitudinally on the slide rod, and by turning the two adjusting knobs, the infusion needle limited by the infusion needle limit sleeve is controlled to move in four directions, thereby controlling the infusion needle to move accurately to a position close to the blood vessel to be infused, and then pressing the knob. The rotating block tightens the second spring, thereby controlling the matching tooth block to move away from the locking tooth, thereby rotating the rotating block, and then driving the infusion needle set on the auxiliary positioning assembly to rotate, thereby adjusting the height and rotation angle of the infusion needle, and further improving the accuracy of operating the infusion needle to move to the blood vessel position. After the adjustment is completed, the adjusting block is released, and the second spring opens to drive the matching tooth block to reset, and the matching tooth block and the locking tooth are locked and stopped, thereby locking the height and rotation angle of the infusion needle. Through the above-mentioned cooperation, it is achieved that when the needle is inserted with the non-dominant hand, the infusion needle can be more accurately controlled to move to the blood vessel position to be infused, so as to improve the accuracy of the infusion needle.

[0019] Fifthly, by setting the connector and the infusion needle limit sleeve as a universal rotation connection, the angle of the infusion needle can be further fine-tuned, thereby further ensuring the accuracy of the infusion needle.

[0020] Sixth, by providing anti-slip grooves on the adjustment knob, the friction between the finger and the adjustment knob can be increased, so that the infusion needle can be more accurately moved manually to a position close to the blood vessel, thereby making the infusion positioning work more accurate.

[0021] Seventh, the bendable metal tube is provided to facilitate adjustment of the angles of the blood vessel fluoroscopy lamp and the lighting lamp, thereby achieving the best lighting and fluoroscopy effects. BRIEF DESCRIPTION OF THE DRAWINGS
