[0002] In the field of pediatric medical care, intravenous infusion as one of the important means of treatment for children's diseases, its effectiveness and safety are directly related to the treatment effect and rehabilitation process of sick children. Because children patients have unique physiological and psychological characteristics, such as tender skin, small blood vessels, strong curiosity, poor self-control ability and easy to move, etc. These characteristics bring many challenges to the management of intravenous infusion, especially the use of hand indwelling needle.

[0003] As a common intravenous infusion tool, the original intention of hand indwelling needle is to reduce the pain of children caused by repeated puncture, and at the same time, it is convenient for nursing staff to carry out drug infusion or blood collection at any time. However, in actual application, children patients often unconsciously move their hands due to curiosity or inability to remain still for a long time, which leads to frequent displacement, dislocation and even accidental extubation of indwelling needle. This not only increases the pain and infection risk of sick children, but also prolongs the hospitalization time, increases the medical cost, and at the same time, it also challenges the work efficiency and nursing quality of nursing staff.

[0004] In order to solve this problem, although there are some hand indwelling needle fixing devices on the market, most of them have design limitations, such as poor fixing effect, poor comfort, affecting the normal activity of children's hands or complicated operation, which is not easy to be accepted by children and parents.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figs. 1 to 4 The child hand indwelling needle protection device shown includes a base pad 1, a protective cover 2, and a wrist restraint mechanism.

[0030] The protective cover 2 is made of rigid plastic, while the base pad 1 is made of a soft material such as cotton, sponge, or silicone. The base pad 1 has an internal support plate to maintain its shape. The protective cover 2 covers the base pad 1 and connects to it at the edge, forming a protective compartment 3 for placing the hand. The protective cover 2 has an observation window 20 in the center, covered by transparent plastic, for observing the protective compartment 3 from the outside. The protective cover 2 has a ventilated structure, specifically multiple vent holes 21 distributed on it. The rear end of the protective cover 2 has an opening for the wrist to pass through, and an outwardly extending upper surround 22 at the opening. The upper surround 22 is a C-shaped plate structure with its concave surface facing downwards.

[0031] The base pad 1 has a lower surrounding part 10 at the corresponding upper surrounding part 22. The lower surrounding part 10 is a C-shaped plate structure with the concave surface facing upward. The upper surrounding part 22 and the lower surrounding part 10 together form a channel for placing the wrist.

[0032] The protective cover 2 is movably connected with the bottom pad 1, and the protective cover 2 can be opened and closed relative to the bottom pad 1. The protective cover 2 is opened to expose the protective compartment 3 for placing hands, and the protective cover 2 is closed to close the protective compartment 3. The protective cover 2 is connected with the bottom pad 1 through a rotating shaft structure 11, the rotating shaft structure 11 is located at the end side of the protective cover 2 away from the opening, and the protective cover 2 is opened and closed through rotation. The protective cover 2 and the bottom pad 1 are also provided with a butt joint fixing structure for limiting the free opening of the protective cover 2. The butt joint fixing structure includes an upper magic tape strip 23 and a lower magic tape strip 12, wherein the upper magic tape strip 23 is fixedly arranged on the lower edge of the protective cover 2, and the lower magic tape strip 12 is fixedly arranged on the upper edge of the bottom pad 1. The protective cover 2 can be temporarily fixed more stably through the upper and lower magic tape strips 12, so as to prevent the protective cover 2 from being easily opened and losing the protective function. The nursing staff or parents can conveniently open the protective cover 2 for operation.

[0033] The protective cover 2 and the bottom pad 1 are also provided with a locking structure, which prevents the opening of the protective cover 2 relative to the bottom pad 1 in the locked state. The locking structure specifically adopts a tightening belt 5 with a lock buckle, which is fixedly connected to the outer side of the upper surrounding part 22 of the protective cover 2 or the bottom of the lower surrounding part 10 of the bottom pad 1. When locking the protective cover 2 and the bottom pad 1 in the closed state, the tightening belt 5 is simultaneously wound around the outer periphery of the upper surrounding part 22 and the lower surrounding part 10 and is tightened, and the lock buckle is buckled.

[0034] The wrist limiting mechanism is arranged on the inner side of the upper surrounding part 22 of the protective cover 2, and the wrist limiting mechanism includes an air bag sleeve 4 for wrapping the wrist to limit movement. The air bag sleeve 4 is a b-shaped structure for wrapping the wrist, specifically, the air bag sleeve 4 is in a “C” shape to adapt to the inner wall of the upper surrounding part 22. The main part of the air bag sleeve 4 is fixed to the inner wall of the upper surrounding part 22, and the two end parts of the air bag sleeve 4 extend downward beyond the edge of the upper surrounding part 22. When the protective cover 2 is closed, the two end parts of the air bag sleeve 4 beyond the edge of the upper surrounding part 22 extend into the lower surrounding part 10 and abut against the inner wall of the lower surrounding part 10. The air bag sleeve 4 forms a notch part 40 between the two end parts. When the air bag sleeve 4 wraps the wrist, the upper surrounding part is provided with a plurality of notches. On the one hand, it can relieve the pressure on the wrist and avoid blocking the blood circulation in the wrist. On the other hand, the extension part of the indwelling needle can be cut into the notch, which is convenient for infusion operation.

[0035] The air bag sleeve 4 is provided with a gas injection port 24 for inflation and deflation, and the gas injection port 24 is located on the outer wall of the upper surrounding part 22. The air bag sleeve 4 is provided with an inflation and deflation device. The inflation and deflation device adopts a pressurized inflation ball or an electric air pump. The inflation and deflation device controls the inflation degree of the air bag sleeve 4 through a plug-in air pipe.

[0036] The protective device is provided with different sizes of large, medium and small models, which are distinguished by XL, L, M, S and XS, so as to meet the needs of children of different ages.

[0037] The specific embodiments described herein merely exemplify the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
