Abstract
Description
Technical Field
[0001] The utility model relates to the medical field, in particular to a PN medicine adding rack for newborns. Background Art
[0002] PN stands for Parenteral Nutrition, which refers to parenteral nutrition. It is the main life support method for premature infants or critically ill newborns in the first stage of life. Babies obtain nutrition through peripheral or central venous channels (intravenous infusion). PN uses a special liquid similar to breast milk and formula milk, which can be injected intravenously to supplement the nutrients such as carbohydrates (sugar), protein, fat, vitamins and minerals needed by babies. These nutrients are first injected into the infusion bag, mixed evenly, and then injected into the newborn for use. During the operation of adding nutrient solution to the infusion bag, the operator holds the infusion bag with one hand and pushes the cap away from the injection port, and takes the syringe containing nutrient solution with the other hand and injects the nutrient solution into the infusion bag. During the operation, the infusion bag is not fixed, and it is easy to touch the injection port and cause contamination when injecting nutrient solution. In addition, the hand holding the infusion bag needs to be kept at a certain height and a certain angle, which is easy to cause fatigue, and then fatigue-related operational abnormalities are easy to occur. After the addition of the medicine, it needs to be manually shaken and weighed, which is a cumbersome and time-consuming step. Utility Model Content
[0003] The utility model relates to a PN medicine adding stand for neonates. The injection port is clamped by a clamp ring and the infusion bag is fixed by a buckle. The operator does not need to hold the infusion bag, which can reduce the work intensity and the operation expertise. The operator can easily complete the medicine adding operation. The clamp ring can be rotated to adapt to the medicine adding operation of the infusion bag at different angles, making the operation more comfortable and convenient. The electronic scale on the base can swing to mix the medicine liquid, and there is no need to manually shake it, so the mixing effect is more sufficient and the reliability is high. At the same time, the electronic scale can accurately measure the amount of medicine, and the functions are diverse and the measurement is accurate.

Detailed Description of the Preferred Embodiments
[0025] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] Referring to Figures 1 to 4 , a neonatal PN medicine adding rack includes a base 1 and a telescopic bracket 2 inserted on the base 1. The telescopic bracket 2 includes a fixed rod 10 at the lower side and a movable rod 11 slidably disposed inside the fixed rod 10. A support seat 3 is provided at the upper end of the movable rod 11. A C-shaped snap ring 4 is provided on one side of the support seat 3, and a U-shaped chuck 5 is provided on the opposite side of the support seat 3 with respect to the snap ring 4; by adjusting the telescopic bracket 2, the height of the injection port of the infusion bag can be adjusted; a support 6 is provided in the middle of the fixed rod 10, and a buckle 7 is provided at the outer end of the support 6. The snap ring 4 and the buckle 7 are located in the same vertical plane. The telescopic bracket 2 and the support member on the telescopic bracket 2 are made of aluminum alloy material, which can be directly disinfected with alcohol, and has a long service life; a swing-type electronic scale 8 is provided on one side of the base 1 for the telescopic bracket 2. The electronic scale 8 can weigh the infusion bag after adding medicine, eliminating the need for a separate weighing device, and the accuracy of the electronic scale 8 can reach 0.1 g, enabling accurate calculation of the weight of the liquid medicine in the infusion bag.
[0027] Further, the opening direction of the chuck 5 is parallel to the width direction of the infusion bag. When placing the medicine adding rack, the infusion bag is parallel to the flowing direction of the laminar air flow, so that the infusion bag will not interfere with the laminar air flow, and it can ensure that the laminar air flow blows bacteria and other pollutants away from the operation area. At the same time, the open end of the pipe cap fixed on the chuck 5 points to the blowing direction of the air flow, which can prevent bacteria and other pollutants from contacting the inner wall of the pipe cap, thereby avoiding contaminating the nutrient solution.
[0028] Further, a first connecting rod 9 connected to the snap ring 4 is arranged on the side surface of the support base 3. One side of the snap ring 4 and the first connecting rod 9 are in an interference-fit hinge connection. After rotating the snap ring 4, relying on the friction force between it and the first connecting rod 9, the snap ring 4 can rotate to the required position and be fixed. When different medicine adding angles are required, the snap ring 4 can be rotated, so that the infusion bag is fixed at an angle, which is convenient for the operator to add medicine.
[0029] Further, an elastic limit block 12 is arranged at the insertion position of the fixing rod 10 on the base 1, and a limit groove 13 corresponding to the limit block 12 is arranged on the side surface of the fixing rod 10. The limit block 12 can stably fix the telescopic bracket 2 on the base 1, and when it is necessary to disinfect the telescopic bracket 2, it can be quickly disassembled.
[0030] Further, referring to Figure 4 , the middle part of the bottom end of the electronic scale 8 is hinged to the base 1. One side of the bottom end of the electronic scale 8 is provided with a motor 14. The motor 14 adopts a small servo motor, which can ensure that the electronic scale 8 stops at the horizontal position every time after swinging, and the swinging speed can be accurately adjusted. The motor 14 is connected to the bottom end of the electronic scale 8 through a transmission mechanism 15. The transmission mechanism 15 includes but is not limited to a cam mechanism. Such reciprocating motion mechanisms are prior arts and will not be elaborated here in detail. A controller 16 is arranged in the base 1. The controller 16 is electrically connected to the motor 14 and the electronic scale 8. A switch 17 is arranged on one side of the fixing rod 10 on the base 1. The switch 17 is electrically connected to the controller 16, and the switch 17 controls the start and stop of the motor 14. Driven by the motor 14, the electronic scale 8 completes the swinging action, and the liquid medicine in the infusion bag can be mixed without manual shaking operation. A display 18 and control buttons 19 are arranged on one side of the top end of the base 1. The display 18 and the control buttons 19 are electrically connected to the controller 16.
[0031] The working principle of the present utility model:
[0032] Before use, first rotate the snap ring 4 to make the inclination angle of the injection nozzle of the infusion bag consistent with the operation requirement; referring to Figure 5, lay the infusion bag flat on the electronic scale 8, then fix the injection nozzle to the snap ring 4, and fix the catheter between the injection nozzle and the infusion bag with the buckle 7; then move the position of the medicine adding rack so that the width direction of the infusion bag is parallel to the flowing direction of the clean laminar airflow; when adding medicine, first fix the tube cap of the injection port to the chuck 5, with the opening of the tube cap pointing to the inflow direction of the laminar airflow, turn on the switch 17, and the electronic scale 8 starts to swing and mix the nutrients in the infusion bag. After the medicine adding operation is completed, first cover the tube cap back on the injection port. After mixing evenly, turn off the switch 17; finally, control the electronic scale 8 through the control button 19 to complete the weighing operation, and the weighed weight is shown on the display 18. After confirmation, the infusion bag can be used for PN infusion treatment; when cleaning and disinfection are required, toggle the limit block 12, remove the telescopic bracket 2 from the base 1, and then disinfect and clean the telescopic bracket 2 and the support member of the telescopic bracket 2.
