Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to an air tightness detection device for pediatric puncture devices. Background Art

[0002] The puncture device is mainly used to puncture specific parts of the human body to obtain tissue samples, inject drugs or perform other medical operations. The basic structure of the puncture device usually includes a puncture needle, a needle holder, a handle and other parts. The puncture needle is a key component and must have sufficient hardness and sharpness to penetrate the skin and tissues smoothly. The needle holder is used to connect the puncture needle and the handle to ensure that the connection between the two is stable. The handle is convenient for medical staff to hold and operate. Some handles are designed with anti-slip textures to enhance operational stability. Children's body parts are smaller than those of adults, and their abdominal cavity, bones and other structures are smaller. Therefore, pediatric trocars are usually thinner and shorter than adult instruments to adapt to children's smaller body cavities and thinner abdominal walls. Pediatric trocars are usually tested for air tightness using air pressure. The pediatric trocar is inserted into a testing device, which inflates, stabilizes the pressure, tests, and releases the pressure to test the air tightness of a single pediatric trocar. The entire process takes half a minute to one minute, and the test efficiency is low. It is not suitable for assembly line production, which in turn causes limitations.

[0003] Therefore, we propose a pediatric trocar airtightness detection device. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a pediatric puncture device airtightness detection device, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0015] 2. The present invention sets a mounting plate in the detection box to divide the space between the partition plates into two parts, an upper part and an lower part. During the process of pulling out the pediatric puncture device, the sealing plate seals the entrance on the mounting plate, so that after the pediatric puncture device is pulled out, the gas under the mounting plate will not leak, thereby causing the air pressure in the detection tank to decrease, affecting the detection of the detection tank.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1: Refer to the attached specification Figure 1 , 2 , 3, 4 and 5, a pediatric puncture device air tightness detection device, comprising: Base 1, detection tank 11, detection box 12 and connecting pipe 13; base 1 and detection tank 11 are fixedly connected to base 1; detection ports 14 are evenly spaced on detection box 12; and sealing member 15 is provided on detection port 14; The detection box 12 is evenly spaced and fixed with partition plates 16; the partition plates 16 are located between the detection ports 14; the two ends of the connecting pipe 13 are respectively connected to the detection box 12 and the detection tank 11; a No. 1 air pressure sensor 17 is fixedly connected to the detection tank 11; an input pipe 18 is provided on the detection tank 11; the input pipe 18 is connected to a high-pressure air source.

[0021] In the present invention, a mounting plate 19 is fixedly connected inside the detection box 12; the partition plate 16 is located on the upper and lower sides of the mounting plate 19; an entrance port 2 is opened on the mounting plate 19; a rubber sealing ring is fixedly connected inside the entrance port 2; a sealing plate 21 is rotatably connected to the mounting plate 19; a sealed electric push rod 22 is hinged on the mounting plate 19; and the output end of the sealed electric push rod 22 is hinged to the sealing plate 21.

[0022] In the present invention, the second air pressure sensor 23 is evenly fixedly connected in the detection box 12 ; the second air pressure sensor 23 is located above the mounting plate 19 ; and the input pipe 18 is also arranged on the detection box 12 .

[0023] In the present invention, the connecting pipes 13 are distributed on the detection tank 11 in a dispersed manner.

[0024] In the present invention, the connecting pipe 13 is fixedly connected and communicated with the electromagnetic valve 3 .

[0025] In the present invention, the input tube 18 is connected to the external air source. When the pediatric puncture device is tested for air tightness, the pediatric puncture device is first inserted into all the test ports 14 so that the seal 15 is sleeved on the outside of the pediatric puncture device, and the pediatric puncture device is inserted into the inlet port 2. Then, high-pressure gas is poured into the test tank 11 and the test box 12 to make the test tank 11 and the test box 12 reach the test air pressure. Since the space between the two adjacent partition plates 16 in the test tank 11 and the test box 12 is connected through the connecting tube 13, when the pediatric puncture device is not airtight, the test tank 11 and the test box 12 are connected to each other. When the air pressure in the detection tank 11 drops, the No. 1 air pressure sensor 17 in the detection tank 11 detects the air pressure drop, thereby detecting that there is a pediatric puncture device with insufficient air tightness among the pediatric puncture devices being detected, and then all the electromagnetic valves 3 on the connecting tubes 13 are closed, and then the first electromagnetic valve 3 is opened. When the first pediatric puncture device has insufficient air tightness, the air pressure detected by the No. 1 air pressure sensor 17 will drop after the first electromagnetic valve 3 is opened, otherwise the air pressure remains unchanged; all the electromagnetic valves 3 are opened and closed in sequence to detect the position of the pediatric puncture device with insufficient air tightness; In the present invention, during the process of pediatric trocar detection, the staff can stagger the time of inserting the pediatric trocar, so that the detection time of the pediatric trocar is staggered, so that when the detection of one part of the pediatric trocar is completed, the detection of another part of the pediatric trocar begins, and after the replacement of the pediatric trocar that has completed the detection is completed, the detection of another part of the pediatric trocar is just completed, thereby improving efficiency; A second air pressure sensor 23 is arranged in the detection box 12, and the second air pressure sensor 23 is located above the mounting plate 19, so that the second air pressure sensor 23 detects the air pressure in real time; in the present invention, when the pediatric puncture device on the detection box 12 is replaced, the pediatric puncture device is pulled out from the detection box 12, and when the lower end of the pediatric puncture device moves to the top of the mounting plate 19, the sealing electric push rod 22 pushes the sealing plate 21, so that the sealing plate 21 seals the inlet 2, and then the pediatric puncture device is pulled out from the detection port 14, at this time, the top of the mounting plate 19 The air leaks from the detection port 14, and the air pressure above the mounting plate 19 decreases. The staff inserts the undetected pediatric puncture device into the detection port 14, and the pediatric puncture device blocks the detection port 14. Then, air is poured into the upper part of the mounting plate 19 in the detection box 12 to increase the air pressure. After the air pressure above the mounting plate 19 is consistent with the air pressure below, the sealing plate 21 is opened again, and the pediatric puncture device passes through the entry port 2, thereby completing the replacement of the pediatric puncture device. Therefore, when the pediatric puncture device is pulled out of the detection port 14, it will not cause the air pressure in the detection tank 11 to decrease. In the present invention, the connecting tube 13 is distributed on the detection tank 11 in a dispersed manner, so that the lower ends of the connecting tube 13 are connected to the detection tank 11 close to each other, thereby reducing the volume of the detection tank 11, thereby preventing the volume of the detection tank 11 from being too large, and preventing the pressure change caused by the leakage of the pediatric puncture device from not changing significantly in the large volume of the detection tank 11, resulting in inaccurate detection; The present invention sets a detection tank 11 and a detection box 12, separates the space in the detection box 12 by a partition plate 16, and then connects the space between the partition plates 16 to the detection tank 11 through a connecting tube 13, so that when the pediatric puncture device inserted between the partition plates 16 is not airtight enough and leaks, the air pressure in the detection tank 11 will be reduced, so that the present invention can detect multiple pediatric puncture devices at one time, and at the same time, a mounting plate 19 is set in the detection box 12 to divide the space between the partition plates 16 into two upper and lower parts. During the process of pulling out the pediatric puncture device, the sealing plate 21 seals the inlet 2 on the mounting plate 19, so that after the pediatric puncture device is pulled out, the gas below the mounting plate 19 in the detection box 12 will not leak from the inlet 2, thereby preventing the air pressure in the detection tank 11 from being reduced and affecting the detection of the detection tank 11.

[0026] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 3 , 4and 5. In the present invention, the sealing member 15 is in the shape of a circular tube.

[0027] In the present invention, a mounting ring 4 is fixedly connected to the detection box 12; support rods 41 are evenly fixedly connected to the sealing member 15; the support rods 41 are circumferentially arranged along the axis of the sealing member 15; a No. 1 support ring 42 is slidably connected to the mounting ring 4; a supporting electric push rod 43 is connected between the No. 1 support ring 42 and the mounting ring 4; a No. 1 stretching rod 44 is hingedly connected between the No. 1 support ring 42 and the support rod 41.

[0028] In the present invention, a second support ring 45 is slidably connected to the mounting ring 4; a supporting electric push rod 43 is also arranged between the second support ring 45 and the mounting ring 4; and a second stretching rod 46 is hinged between the second support ring 45 and the support rod 41.

[0029] In the present invention, the sealing member 15 is configured to be in a circular tubular shape, so that after the pediatric trocar is inserted into the sealing member 15, there are more contact surfaces between the circular tubular sealing member 15 and the pediatric trocar, thereby achieving a better sealing effect; In the present invention, a support rod 41 is arranged on the sealing member 15. Before the pediatric puncture device enters the sealing member 15, two supporting electric push rods 43 pull the No. 1 support ring 42 and the No. 2 support ring 45, so that the No. 1 support ring 42 and the No. 2 support ring 45 pull the No. 1 stretching rod 44 and the No. 2 stretching rod 46, so that the No. 1 stretching rod 44 and the No. 2 stretching rod 46 simultaneously pull the support rod 41, so that the support rod 41 pulls the sealing member 15 outward to expand the sealing member 15, and then the pediatric puncture device is inserted into the sealing member 15, and the support rod 41 returns to its original position, so as to facilitate the pediatric puncture device. The puncture device is inserted into the sealing member 15 to prevent the cylindrical sealing member 15 from having a large contact area with the pediatric puncture device, thereby causing a large friction force and making it difficult to insert the pediatric puncture device; the No. 1 support ring 42 and the No. 2 support ring 45 simultaneously pull the No. 1 stretching rod 44 and the No. 2 stretching rod 46, so that the upper and lower ends of the support rod 41 can move outward at the same time, and the situation where one end of the upper and lower ends is pulled while the other end moves inward will not occur. At the same time, the support rod 41 can squeeze the sealing member 15 to improve the sealing performance between the sealing member 15 and the pediatric puncture device; The present invention arranges the sealing member 15 into a cylindrical shape so that the contact surface between the pediatric puncture device and the sealing member 15 is larger, thereby improving the sealing effect. At the same time, a No. 1 support ring 42 and a No. 2 support ring 45 are arranged to pull the support rod 41 on the sealing member 15, thereby facilitating the insertion of the pediatric puncture device. The situation in which the contact surface between the sealing member 15 and the pediatric puncture device is large, the friction force is also large, and the pediatric puncture device is difficult to insert will not occur.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected; the scope of the present invention to be protected is defined by the attached claims and their equivalents.
