Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to infusion leaks alarm device outward.
Background
The change of the body position or the hand position of the patient during transfusion can cause liquid to leak into the skin, thereby causing the skin to bulge. The skin bulge process is slow, so that the patient and the nurse are difficult to perceive the skin bulge, and when the patient feels pain, the skin bulge is already a little larger (probably the size of the soybean); even for patients with less pain, the height and area of the skin bulge is increased. If can in time discover the skin arch, the nurse alright in time adjust the position of patient's palm or the position of infusion syringe needle prevents that liquid from leaking outward and aggravates, avoids the protruding scope of skin to enlarge, so we need a device that can monitor the infusion and leak outward at the infusion in-process to and remind nurse and patient in time.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1, 2 and 3, the infusion leakage alarm device comprises a patch 1, a pressure-proof box 2 without a bottom surface, an induction bar 7, an elastic pull strip 5, a fixed block 4, a switch and an alarm 9. The patch 1 is used to contact the skin, fixing the whole device on the skin; the patch 1 is hollow, so that the induction strip 7 can be conveniently contacted with the skin, and the leakage of the infusion liquid can be found in time. The pressure-proof box 2 is arranged on the patch 1, and the bottom of the pressure-proof box is opposite to the hollow part of the patch 1; in order to prevent the pressure-proof box 2 from influencing the transfusion, a crescent notch 3 can be arranged at the lower end of the rear wall of the pressure-proof box 2. The induction strip 7 is inelastic, is soft and can be bent and can be an inelastic cloth strip; one end of the induction strip 7 is connected with the lower end of the rear wall of the pressure-proof box 2, and the other end of the induction strip 7 extends out of the lower end of the front wall of the pressure-proof box 2 and is connected with one end of the elastic brace 5; the other end of the elastic brace 5 is connected with the fixed block 4, the fixed block 4 is fixed on the paster 1, and the elastic brace 5 enables the induction strip 7 to keep a tightening state. The switch comprises a first end 8 of the switch and a second end 6 of the switch, the first end 8 of the switch is arranged on the patch 1, and the second end 6 of the switch is arranged on the outer side of the induction bar 7; the first end 8 of the switch is connected with the second end 6 of the switch through an alarm 9; when the infusion liquid leaks and the skin is raised, the induction strip 7 drives the second end 6 of the switch to move, so that the first end 8 of the switch is contacted with the second end 6 of the switch, the circuit of the alarm 9 is closed, and the alarm 9 gives an alarm.
When the anti-pressing box is used, the center of the anti-pressing box 2 is aligned with the needle point, the rear wall of the anti-pressing box 2 faces one side of the needle tail, the needle tail or the small infusion hose is arranged at the notch 3, and an elastic plug (such as a rubber plug) can be arranged at the notch 3 in order to prevent dust from entering the anti-pressing box 2 and fix the needle tail or the small infusion hose.
In order to improve the stability of the whole device, ensure the compactness of the structure and reduce the volume, the alarm 9 can be arranged in the pressure-proof box 2 and fixed on the pressure-proof box 2. In order to improve the sensitivity of the device, 2 switches can be used, which are respectively arranged at two sides of the induction bar 7.
When the patch is used, the center of the pressure-proof box 2 is approximately aligned with the needle point, the notch 3 is aligned with the direction of the needle tail, and then the patch 1 is pasted on the skin. At this time, the elastic plug presses the needle tube or the small infusion tube at the rear side of the needle tube, so that the outward leakage of the infusion due to the tilting of the needle tip caused by the pressing of the needle tail by the pressure-proof box 2 can be prevented, or the reduction of the infusion flow speed caused by the deformation of the small infusion tube caused by the pressing of the small infusion tube by the pressure-proof box 2 can be prevented. The sensing strip 7 is tightly attached to the skin, and the sensing strip 7 is kept in a tight state through the elasticity of the elastic pull strip 5. When the infusion liquid leaks, the skin bulges, the bulged skin jacks up the induction strip 7 upwards, so that the induction strip 7 moves towards the center of the pressure-proof box 2, and the horizontal component force towards the center of the pressure-proof box 2 is larger according to stress analysis; and because the inductive strip 7 is made of non-elastic flexible materials, the inductive strip 7 can be dragged towards the center of the pressure-proof box 2 by the raised skin, so that the second end 6 of the switch is driven to be close to the first end 8 of the switch. Along with the continuous protrusion of the skin, the induction bar 7 continuously moves towards the center direction of the pressure-proof box 2, and the second end 6 of the switch and the first end 8 of the switch are connected. No matter which side of the two sides of the induction strip 7 is opened or closed, the alarm can generate a peak sound to remind patients and medical staff that the infusion liquid leaks.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
