Description

Technical Field

[0001] The utility model relates to the technical field of infusion auxiliary equipment, in particular to an indwelling needle protection device. Background Art

[0002] An indwelling needle is a common infusion tool that places a soft catheter in a blood vessel to achieve long-term infusion therapy. The use of an indwelling needle can reduce the patient's pain caused by repeated venous punctures and the fear of injections, reduce the patient's anxiety, facilitate the rescue and medication of emergency and critically ill patients, reduce the workload of nurses, and reduce the patient's pain. However, indwelling needles have the following problems during use: Since indwelling needles often need to be retained in the patient's body for about four to five days, when the patient takes a bath, water can easily come into contact with the dressing that fixes the indwelling needle, causing the dressing to fall off due to insufficient viscosity. The indwelling needle loses its fixing effect and is easily removed from the patient's blood vessel. At the same time, it is easy for water to enter the indwelling needle, causing harm to the patient. Utility Model Content

[0011] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0012] Depend on Figures 1 to 5 It is given, including a rectangular main body sleeve 1, with thumb sleeves 2 at the left and right ends of the main body sleeve 1 respectively, a compression air bag 3 is provided on the upper side wall of the main body sleeve 1, and an isolation groove 4 is provided on the compression air bag 3. An inflation block 5 in the front and rear directions is provided on the upper end of the main body sleeve 1, and a front and rear axial piston hole 6 is opened at the front end of the inflation block 5. A piston column 7 that can slide back and forth is coaxially provided in the piston hole 6. An inflation tube 8 with an upper and lower axial direction and inserted into the compression air bag 3 is provided on the rear side of the inflation block 5, and the upper end of the inflation tube 8 is connected with the piston hole 6.

[0013] In order to facilitate pressing the piston column 7, the piston column 7 is slidably connected to the piston hole 6, and the front end of the piston column 7 extends out of the piston hole 6 and is provided with a pressure plate 9.

[0014] In order to facilitate the resetting of the piston column 7 , a compression spring 10 is mounted on the piston column 7 and is located between the pressure plate 9 and the inflatable block 5 .

[0015] In order to facilitate air inhalation, an air inhalation pipe 11 is provided at the upper end of the inflatable block 5 in an up-and-down axial direction, and the lower end of the air inhalation pipe 11 is communicated with the piston hole 6 .

[0016] In order to facilitate inflation, the inflation pipe 8 and the air intake pipe 11 are respectively provided with a one-way valve 12 with the opening facing downward.

[0017] In order to facilitate deflation, the compressed air bag 3 is provided with a deflation pipe 13 located on the right side of the inflatable block 5, and a plug 14 is detachably connected to the upper end of the deflation pipe 13.

[0018] For ease of use, the main body cover 1 and the thumb cover 2 are both made of hard plastic.

[0019] In order to increase the waterproof effect, a waterproof cloth 15 is provided in front of the main body cover 1.

[0020] In order to prevent liquid from flowing in from the thumb and the back, elastic tightening sleeves 16 are respectively provided in front of the thumb sleeve 2 and the front of the main sleeve 1.

[0021] When the utility model is used, the main body cover 1 is first worn on the hand on the side where the indwelling needle is retained. When the indwelling needle is located on the left hand, the main body cover 1 can be worn on the patient's left hand, and the thumb can be inserted into the thumb cover 2 on the right. If the indwelling needle is located on the patient's right hand, the main body cover 1 can be worn on the right hand and the thumb of the right hand can be inserted into the thumb cover 2 on the left. After wearing, the pressing plate 9 is pressed backward, and the pressing plate 9 drives the piston column 7 to move backward in the piston hole 6 and compress the compression spring 10 backward. The piston column 7 moves backward in the piston hole 6 to squeeze the gas in the piston hole 6 into the inflation tube 8. At this time, the one-way valve 12 in the suction tube 11 can prevent the gas in the piston hole 6 from being squeezed to the outside.

[0022] The air in the piston hole 6 is squeezed into the compressed air bag 3 through the inflation tube 8, so that the compressed air bag 3 gradually expands and becomes larger. At the same time, the one-way valve 12 in the inflation tube 8 can prevent the gas entering the compressed air bag 3 from flowing out in the opposite direction. After being squeezed backward for a distance, the piston column 7 moves backward to the rearmost position in the piston hole 6, and then the pressure plate 9 is released. The pressure plate 9 drives the piston column 7 to move forward due to the restoring force of the compression spring 10. The piston column 7 moves forward to reduce the pressure in the piston hole 6, forming a vacuum, and then the outside air is sucked into the piston hole 6 through the suction pipe 11. At this time, the one-way valve 12 in the inflation tube 8 can prevent the gas in the compressed air bag 3 from being re-sucked into the piston hole 6. The piston column 7 moves forward for a distance and then returns to the initial position. At this time, the piston hole 6 is filled with air again. At this time, the pressure plate 9 is pushed backward again, and the pressure plate 9 drives the piston column 7 to move backward again, so that the compressed air bag 3 is inflated again, and then it is released again;

[0023] This is repeated for many times, and air is repeatedly injected into the compressed airbag 3, so that the compressed airbag 3 gradually becomes larger. After a period of time, the compressed airbag 3 contacts the back of the patient's hand and squeezes and fixes the back of the patient's hand. At the same time, the indwelling needle on the back of the patient's hand is located in the isolation groove 4 of the compressed airbag 3, and the indwelling needle and the fixed dressing on it are isolated in the isolation groove 4. When taking a bath, the compressed airbag 3 wraps the indwelling needle therein to prevent water from contacting the indwelling needle, thereby protecting the indwelling needle and preventing the indwelling needle from getting into water and falling off. The elastic tightening sleeve 16 at the rear end of the thumb sleeve 2 and the main sleeve 1 can tighten the skin of the thumb and the back of the hand to prevent water from entering through the thumb during bathing, thereby increasing the waterproof effect. When the patient finishes bathing, the water on the main sleeve 1 and the thumb sleeve 2 is wiped dry, and then the plug 14 on the venting tube 13 is removed. After removal, the gas in the compressed air bag 3 flows out, and the compressed air bag 3 is deflated and becomes smaller, thereby releasing the squeezing and fixation of the patient's back of the hand skin, and then releasing the fixation, so that the patient can take the hand out of the main sleeve 1 and the thumb sleeve 2.

[0024] Compared with the prior art, the beneficial effects of the utility model are: the main body cover, thumb cover, compressed air bag, etc. can protect the patient's hand on the side of the indwelling needle, and at the same time, the indwelling needle is partially located in the isolation groove and is surrounded and protected by the compressed air bag on all sides to prevent liquid from entering the indwelling needle or causing the indwelling needle to fall off during bathing and contact with water. The elastic tightening cover can enhance the waterproofness of the main body cover, and the pressure plate can facilitate medical staff to press the piston column. This structure is simple, novel in conception, easy to use, and highly practical.
