Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a multifunctional nursing pliers. Background Art
[0002] As a commonly used medical device, the heparin cap is an indispensable device in the clinical indwelling infusion process. The traditional heparin cap is composed of a shell with a spiral interface and a rubber puncture piece. It is connected to the interface of the infusion line during clinical use, and the rubber puncture piece is pierced with an injection puncture device to deliver liquid medicine or extract blood and other body fluids. When the heparin cap is used clinically, the appearance of the catheter indwelling in the patient's body can be sealed to keep the catheter sterile. After each infusion, the clinical nurse can use sodium heparin or saline to seal the indwelling catheter through the heparin cap, and then close the water-stop clip to prevent the patient's blood from flowing back. However, due to the influence of the principle of thermal expansion and contraction, the heparin cap or positive pressure connector sometimes cannot be screwed off when it is replaced during PICC or CVC maintenance. Clinically, it can only be assisted by tools such as hemostatic forceps.
[0003] At present, critically ill patients are often treated with heparin caps during clinical infusion therapy, but it is often difficult to pull out the heparin caps and ventilator air inlet connectors. There is no corresponding tool to solve this problem, and we can only try to open them by changing the debugging strength of different personnel, which wastes the manpower and time of nursing staff, especially in emergency situations such as rescue. It is even more necessary to open these connectors as soon as possible. Due to the needs of the disease, we hope to have a convenient and fast tool that can ensure patient safety according to the actual clinical needs, and can effectively remove various connectors such as the infusion connector heparin cap and the ventilator air inlet connector.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0028] like Figure 1 and Figure 2 As shown, the utility model provides a multifunctional nursing pliers, including a first pliers body and a second pliers body, the first pliers body and the second pliers body are connected by a riveted shaft 5, the first pliers body includes a first pliers handle 3 and a first pliers head 1, the second pliers body includes a second pliers handle 4 and a second pliers head 2, which includes: a heparin cap screwing portion and an air intake joint pulling portion, the heparin cap screwing portion is arranged on the inner side of the first pliers head 1 and the second pliers head 2, the air intake joint pulling portion is arranged on the inner side of the first pliers handle 3 and the second pliers handle 4, an air intake joint ejection assembly is arranged on the inner side of the first pliers handle 3, and an air intake joint fixing block 8 is arranged on the inner side of the second pliers handle 4.
[0029] The technical solution of the utility model is to set a heparin cap screwing part on the inner side of the first clamp head 1 and the second clamp head 2, put the heparin cap into the heparin cap screwing part, hold the first clamp handle 3 and the second clamp handle 4 firmly, and rotate them to unscrew the heparin cap. When the air inlet joint needs to be opened, put the air inlet joint into the air inlet joint extraction part, support the air inlet joint with the air inlet joint fixing block 8, insert the end of the air inlet joint ejection assembly into the seam of the air inlet joint, press the first clamp handle 3 and the second clamp handle 4 inward, gradually eject the air inlet joint, and pull out the air inlet joint. The tool can be used to quickly and conveniently complete the screwing of the heparin cap and the extraction of the air inlet joint without changing a variety of different tools, saving time and effort.
[0030] The first clamp head 1 and the second clamp head 2 are both provided with grooves on their inner sides. A plurality of clamp teeth are provided on the grooves on the inner sides of the first clamp head 1 and the second clamp head 2. When in use, the heparin cap is placed into the heparin cap screwing part, specifically, into the grooves on the inner sides of the first clamp head 1 and the second clamp head 2, and the first clamp handle 3 and the second clamp handle 4 are firmly grasped and rotated counterclockwise to unscrew the heparin cap.
[0031] The air inlet joint ejection assembly includes a first air inlet joint ejection block 6 and a second air inlet joint ejection block 7. The distance between the first air inlet joint ejection block 6 and the second air inlet joint ejection block 7 is smaller than the diameter of the air inlet joint. The thickness of the first air inlet joint ejection block 6 gradually decreases from the side close to the first clamp handle 3 to the side away from the first clamp handle 3, and the cross-sectional shape of the first air inlet joint ejection block 6 is a triangle. The thickness of the second air inlet joint ejection block 7 gradually decreases from the side close to the first clamp handle 3 to the side away from the first clamp handle 3, and the cross-sectional shape of the second air inlet joint ejection block 7 is a triangle, as shown in FIG. Figure 2 As shown, the ends of the first air inlet joint ejection block 6 and the second air inlet joint ejection block 7 are more easily inserted into the air inlet joint joint seam. When in use, the air inlet joint of the ventilator is placed into the air inlet joint extraction part, and the ends of the first air inlet joint ejection block 6 and the second air inlet joint ejection block 7 are respectively inserted on both sides of the air inlet joint joint seam position. In the process of pressing the first clamp handle 3 and the second clamp handle 4 inwardly to close, the first air inlet joint ejection block 6 and the second air inlet joint ejection block 7 force the two sections of the air inlet joint connection to gradually separate due to their wedge-shaped structures.
[0032] A groove is provided on one side of the air intake joint fixing block 8 away from the second clamp handle 4. Providing the groove here enables the air intake joint to fit more closely with the air intake joint fixing block 8, preventing the upper part of the air intake joint from sliding out of the air intake joint extraction portion when the air intake joint is pulled out.
[0033] The multifunctional nursing pliers further include a bottle cap prying portion 9, which is arranged at the bottom end of the first pliers handle 3. The bottle cap prying portion 9 can also be arranged at the bottom end of the second pliers handle 4. By arranging the bottle cap prying portion 9, when encountering a situation where the bottle cap needs to be pried, the multifunctional nursing pliers can be used to open the bottle cap, which is more convenient to use.
[0034] The material of the multifunctional nursing pliers is chrome vanadium steel. When making the multifunctional nursing pliers, firstly, molds for the left and right sides of the pliers are made, and then the chrome vanadium steel is put into the mold for stamping and forming, and the excess steel is removed, and then the milling cutter on the broaching machine is put into place to make the pliers teeth on the grooves of the first pliers head 1 and the second pliers head 2, and the left and right sides of the pliers are riveted together with the riveting shaft 5, and polished and smoothed to make the finished pliers.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
