Description

Technical Field

[0001] The utility model relates to the technical field of medical testing equipment, in particular to a convenient-to-use testing sampling device for medical testing. Background Art

[0002] Medical testing is a science that tests materials taken from the human body in microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology, etc., to provide information for the prevention, diagnosis, treatment of human diseases and the assessment of human health. Through systematic learning, we will learn how to identify a person's blood type, determine whether a person is anemic, whether the liver function is normal, etc. This subject requires the use of various photoelectric instruments and chemical reagents to complete experimental analysis, so it focuses on science and requires a good foundation in biology and chemistry.

[0003] In the process of medical examination, a sampling device is usually used to test samples. The traditional method is for the physician to draw samples through a syringe and then conduct a fixed-point test. This method relies more on the physician's experience and cannot release samples at a fixed point and in a quantitative manner, resulting in certain waste and inconvenience in use. Based on this, we propose an easy-to-use sampling device for medical examination. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: when the structure is in use, the user picks up the syringe body and places the needle on the sample to be drawn. After the drawing is completed, the sample needs to be quantitatively released. At this time, the threaded barrel and the threaded strip are rotated upward, and the scale line is adjusted to a suitable position. At this time, the spring applies elastic force to the limit ring, and the limit ring and the gasket ring fit the rotation of the limit threaded barrel, so that the threaded barrel is in a stable position to avoid slipping. When releasing the sample, the top plate and the hollow pillar are pressed down to drive the hollow pillar to move downward to push the sealing piston to move and inject the sample.

When multiple injections are required, the elastic automatic telescopic locking mechanism is pressed to drive the support rod to move upward to release the lock of the rack on the top plate, so that the top plate and the bottom mechanism move up and the locking position moves up, and then the elastic automatic telescopic locking mechanism is pressed again to press the hollow support column downward under the original scale limit, and perform the injection according to the previous preset scale amount. The overall use effect is good and it is convenient for multiple injections. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: a convenient-to-use sampling device for medical inspection, comprising a syringe body 1, a sealing piston 18 is movably sleeved on the inner side of the syringe body 1, a hollow pillar 7 is fixedly installed on the top of the sealing piston 18, a top plate 5 is movably inserted on the outer side of the top of the hollow pillar 7, a second support plate 4 is fixedly installed on both sides of the top plate 5, a slide plate 3 is fixedly installed on the bottom of the second support plate 4, a limiting cone 11 is fixedly installed on the bottom end of the slide plate 3, a first support plate 2 is fixedly installed on both sides of the top of the syringe body 1, a threaded strip 12 is arranged on the outer side of the syringe body 1, a threaded barrel 10 is threadedly connected to the outer side of the threaded strip 12, a gasket 13 is fixedly installed on the bottom of the threaded barrel 10, and the syringe body 1 is provided with a threaded barrel 10. A scale line 9 is arranged on the outside, a limit ring 14 is movably sleeved on the outside of the syringe body 1, a spring 15 is fixedly installed on the bottom of the limit ring 14, a fixing ring 16 is fixedly installed on the bottom of the spring 15, a needle 17 is movably installed on the bottom of the syringe body 1, limit slide grooves 8 are arranged on the four sides of the hollow pillar 7, a rack 20 is movably installed on the inside of the limit slide groove 8, an elastic rubber strip 23 is fixedly installed on the opposite side of the rack 20, a plurality of fixed inner cone sections 22 are fixedly installed on the opposite side of the rack 20, an elastic automatic telescopic locking mechanism 6 is installed on the top end of the hollow pillar 7, a support rod 19 is fixedly installed on the output end of the elastic automatic telescopic locking mechanism 6, and a plurality of push cones 21 are fixedly installed on the outside of the support rod 19.

[0020] The working principle of the above technical solution is as follows: when in use, the user picks up the syringe body 1 and places the needle 17 on the sample to be drawn. After the drawing is completed, the sample needs to be released quantitatively. At this time, the threaded barrel 10 and the threaded strip 12 are rotated upward, and the scale line 9 is adjusted to a suitable position. At this time, the spring 15 applies elastic force to the limiting ring 14, and the limiting ring 14 and the gasket ring 13 fit the rotation of the limiting threaded barrel 10, so that the threaded barrel 10 is in a stable position to avoid slipping. When releasing the sample, the top plate 5 and the hollow pillar 7 are pressed down to drive the hollow pillar 7 to move downward and push the sealing piston 18 to move to inject the sample. When the top plate 5 moves downward, it drives the slide plate 3 and the limiting cone 11 to move downward. Since the threaded barrel 10 is adjusted to a fixed position, the limiting cone 11 will fit with the top of the threaded barrel 10 after moving downward to block it. At this time, only the limiting amount at the top of the scale line 9 is injected, which is convenient for quantitative injection and stable use.

[0021] In another embodiment, Figure 1-Figure 3 As shown, the slide plate 3 is arc-shaped and fits on the outside of the syringe body 1. The slide plate 3 movably passes through the first support plate 2 and extends to the bottom of the first support plate 2. The limiting cone 11 is movably sleeved on the outside of the syringe body 1, and the limiting cone 11 and the top of the threaded barrel 10 are movably in contact with each other.

[0022] The slide plate 3 and the limiting cone 11 are slidably limited on the outer side of the syringe body 1, which is convenient for stable movement and stable sliding limitation of the top structure, which is convenient for structural stability to avoid locking and increase structural strength.

[0023] In another embodiment, Figure 1-Figure 3 As shown, the threaded cylinder 10 and the gasket ring 13 are both movably sleeved on the outer side of the syringe body 1, and the gasket ring 13 is in movably contact with the top of the limiting ring 14.

[0024] The threaded barrel 10 is threadedly connected to the threaded strip 12 on the outside of the syringe body 1, so that it can move with the position of the gasket ring 13 after rotation. When moving, the limiting ring 14 fits with the top of the gasket ring 13 to increase friction and fix the position of the gasket ring 13 and the limiting cone 11, avoiding slippage of the threaded barrel 10 during use, stabilizing the limiting structure, and achieving good use effect.

[0025] In another embodiment, Figure 1-Figure 3 As shown, the fixing ring 16 is fixedly sleeved on the outer side of the syringe body 1, and the spring 15 is movably sleeved on the outer side of the syringe body 1.

[0026] The fixing ring 16 and the spring 15 facilitate the upward and downward movement of the limiting ring 14 , so that the limiting ring 14 can be closely fitted to the bottom of the gasket ring 13 , which is convenient for auxiliary limiting and has a good overall use effect.

[0027] In another embodiment, Figure 3 and Figure 4 As shown, the pushing cone 21 and the fixed inner cone section 22 are linearly distributed on the outer side of the support rod 19 and the inner side of the limiting slide groove 8 respectively, and the fixed inner cone section 22 is evenly distributed on the inner side of the limiting slide groove 8 with the support rod 19 as the circumference. The specifications and dimensions of the pushing cone 21 are compatible with the specifications and dimensions of the fixed inner cone section 22, and the inner side of the top plate 5 is provided with a notch compatible with the rack 20 and the hollow pillar 7.

[0028] When multiple quantitative injections are required, the elastic automatic telescopic locking mechanism 6 can be pressed. The elastic automatic telescopic locking mechanism 6 is similar to the lifting locking mechanism of an automatic ballpoint pen. When the output end of the elastic automatic telescopic locking mechanism 6 is extended, the support rod 19 is driven to move downward, so that the cone 21 is pushed downward to fit the fixed inner cone section 22, and the fixed inner cone section 22 is pushed outward, so that the fixed inner cone section 22 pushes the rack 20 to slide outward inside the limiting slide groove 8, so that the outer side of the rack 20 is clamped at the corresponding position of the top plate 5, so that the position of the hollow pillar 7 and the top plate 5 is fixed, and the injection operation can be performed. When multiple injections are performed, the elastic automatic telescopic locking mechanism 6 is pressed to drive the support rod 19 to move upward to release the locking of the rack 20 on the top plate 5, so that the top plate 5 and the bottom mechanism move upward to move the locking position upward, and then the elastic automatic telescopic locking mechanism 6 is pressed again, so that the hollow pillar 7 is pressed downward under the original scale limit, and the previous preset scale is injected. The overall use effect is good and it is convenient for multiple injections.

[0029] In another embodiment, Figure 3 and Figure 4 As shown, the bottom of the support rod 19 is movably inserted into a preset hole inside the hollow pillar 7, and the limiting sliding groove 8 and the rack 20 are evenly distributed on the inner side of the hollow pillar 7 in a circumferential manner.

[0030] The support rod 19 slides inside the hollow pillar 7 to avoid deviation. The top of the hollow pillar 7 is a hollow middle section and the bottom is in a closed state, which is convenient for installing and using the mechanism. The limiting slide groove 8 and the rack 20 can stabilize the structural torque when locked, increase stability and avoid deflection.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
