The buoyancy principle of the liquid stopping floating plug device in a sodium chloride solution is verified, and the specific verification steps are as follows:
weighing the weight of the liquid stopping floating plug device on an electronic scale; the liquid medicine can flow in from the gap when the liquid medicine is infused according to theoretical calculation of the design size of the product, so that the self weight is increased, and the locking force is improved; weighing the weight of water filled in a lower cover hollow groove 21 of a lower cover 20 of the liquid stopping floating plug on an electronic scale; the liquid-stopping floating plug device is verified and designed according to theoretical calculation of product design size, can automatically float under the action of buoyancy when liquid medicine is soaked, and part of the liquid medicine is exposed out of the liquid level.
And step two, testing according to the using method of the infusion apparatus, placing the liquid-stopping floating plug device in the dropping funnel, inserting the puncture outfit into a 0.9% sodium chloride solution infusion bottle, and performing visual observation and verification to obtain the requirements.
Wherein, the specific theoretical calculation and test results are illustrated as follows:
theoretical calculation result
And (3) derivation of a mechanical formula: when the object is in suspension, F float is G weight (unit: F float is buoyancy N; G weight is gravity N of the object); when the object is floating, F-float is in rho gV rows (unit: F-float is buoyancy N; rho is density kg/m)3The density of the 0.9% sodium chloride solution was about 1X 103kg/m3(ii) a g is 10N/kg; v rows volume m of liquid displaced by the object3(ii) a Row V ═ lower cap base area × immersion depth); therefore, the immersion depth is V rows ÷ lower cover bottom area ÷ (F float/. ρ g) ÷ lower cover bottom area ÷ V rows ÷ lower cover bottom area ÷
The bottom area of the lower cover is S ═ r2 ≈ 9.5 x 10-5m2
1. Taking three components of the liquid stopping floating plug device, and weighing the components as follows: 0.926X 10-3、0.895×10-3、0.903×10-3And calculating the average mass of the liquid stopping floating plug as follows: m is approximately equal to 0.908 multiplied by 10-3kg, i.e. the gravity G is mg to 9.08X 10 when the infusion is just started and the liquid stopping floating plug lower cover is not filled with the liquid medicine-3N; if the lower cover of the liquid stop floating plug is not provided with the hollow groove of the lower cover, when the lower cover floats on the liquid level, the buoyancy is equal to the gravity, and the theoretical immersion depth is calculated: 9.08X 10-3÷9.5×10-5≈0.955×10-2m
Because 0.955X 10-2m＞0.85×10-2m (the size of the hollow groove of the lower cover), so that the liquid medicine can flow in from the gap when the liquid medicine is infused, thereby increasing the self weight and improving the locking force.
2. Weighing three liquid-stopping floating plugs on an electronic scale, and weighing the mass (kg) of water filled in a lower cover hollow groove of a lower cover of the liquid-stopping floating plug: 1.438X 10-3、1.405×10-3、1.412×10-3Taking the average value as: 1.418X 10-3kg, i.e. the gravity G mg 1.418 x 10 when the hollow groove of the lower cover of the lower stop floating plug is filled with the liquid medicine-2N, when the floating body floats on the liquid level, the buoyancy is equal to the gravity, and the theoretical immersion depth is calculated as follows: 1.418X 10-2÷0.95×10-4≈1.493×10-2m
Because 1.493 x 10-2m＜2.15×10-2m (the total height of the liquid stopping floating plug device), so the liquid stopping floating plug can automatically float under the action of buoyancy when the liquid medicine is soaked,and a portion is exposed to the liquid surface. The gravity when the lower cover hollow groove of the lower cover of the liquid-stopping floating plug is filled with the liquid medicine is 1.418 multiplied by 10-2N, is also the final latching force.
(II) test results
The liquid-stopping floating plug device is tested according to the using method of the infusion apparatus, the puncture outfit is inserted into a 0.9% sodium chloride solution infusion bottle, and the result is observed visually:
moreover, the whole outer diameter of the liquid-stopping floating plug device can ensure that a certain gap is reserved between the whole outer diameter of the liquid-stopping floating plug device and the edge of the inner wall of the dropping funnel, so that the liquid-stopping floating plug device can vertically and automatically lift along with the lifting of the liquid medicine in the dropping funnel; the liquid-stopping floating plug device can automatically float under the action of buoyancy when the liquid medicine is soaked, and a part of the device is exposed out of the liquid level.
And this end liquid floating plug device has can realize the function of automatic end liquid when the liquid medicine is transfused: when the liquid level descends, the liquid stopping floating plug device can descend along with the liquid stopping floating plug device until the liquid outlet of the dropping funnel is blocked, so that the liquid in the liquid conveying pipeline below the liquid stopping floating plug device can automatically stop flowing, and no air enters; meanwhile, the dropping funnel can still maintain the self-sealing performance when being vertical or inclined; when the liquid medicine is infused again, the liquid stopping floating plug device can be made to bounce integrally by extruding the infusion pipeline below the dropping funnel, and the normal infusion of the liquid medicine is resumed.
In conclusion, when the liquid level descends, the whole liquid stopping floating plug device can descend along with the liquid stopping floating plug device until the liquid stopping floating plug silica gel membrane 30 blocks the liquid outlet, so that the liquid in the part of the infusion pipeline below the liquid stopping floating plug device can automatically stop flowing, and no air enters; the liquid stopping floating plug device is used for replacing the connection between a traditional dropping funnel and a liquid stopping film, the problem of functional failure caused by the damage of the liquid stopping film to a product is avoided, the safety of clinical transfusion is guaranteed, and medical accidents are avoided.
