Description

Safety lock device for intravenous infusion

The invention relates to a safety lock device, in particular to a safety lock device for intravenous infusion.

Intravenous infusion is a common and important medical treatment that provides patients with infusion therapy in clinical practice. The nurse will set the flow rate of the infusion according to the doctor's instructions, and regularly check the status of the intravenous infusion within the expected time.

Regarding the infusion flow rate, the "infusion flow rate push-wheel regulator" is generally used to adjust the infusion flow rate. However, during the infusion treatment of the patient, the patient or his caregivers may privately close the tube clamp or adjust the infusion flow rate for various reasons. The device causes the drip flow rate to be abnormal, which makes the actual injection completion time of the drip and the estimated time of the medical staff have a gap; and the infusion flow rate is set according to the drug manual and doctor's order. Different drugs, the drip flow rate is also fast or slow. If the patient or his caregivers privately adjust the flow rate of the drip, it will greatly affect the treatment and cause complications. In severe cases, symptoms such as shock and respiratory failure may lead to death.

Therefore, the development of an intravenous infusion safety lock device to fix the flow rate of intravenous infusion and to improve the quality of intravenous infusion medical care is indeed a major issue in the field of medical care.

The idea is that the inventor of the present invention is based on the concept of continuous product research and innovation, based on years of practical experience in product design and development, and active research and development thinking, through countless actual tests and experiments, leading to the invention of this invention.

The purpose of the present invention is to provide a fixed intravenous infusion safety lock device suitable for any general infusion set, which is used to prevent patients or their caregivers from adjusting the intravenous flow rate or closing the tube clamp during intravenous infusion treatment. , Resulting in an abnormal drip flow rate, which does not meet the correct flow rate set by the doctor’s advice, leading to serious complications.

To achieve the above objective, the present invention includes a lock box for accommodating an infusion flow rate push-wheel regulator, the lock box includes a first cover, a second cover, the first cover, The second cover is pivotally movable, the first cover has an elastic plate on one side of the inner wall, the elastic plate has a hole, and the surface of the second cover has at least one unlocking hole corresponding to the elastic plate. The inner wall of the two covers has a locking part corresponding to the locking hole, and the locking part is used to be locked in the locking hole.

The infusion flow rate push-wheel regulator is locked in the lock box by the locking function of the locking part and the card hole, and the lock box cannot be opened manually, which can effectively fix the flow rate of the drip and effectively reduce the medical staff’s worry about the patient or their care The family members of privately adjust the flow rate of the drip, which affects the effectiveness of the treatment, and causes serious complications, leading to the occurrence of medical disputes, and effectively reduces the nursing hours and medical manpower, achieving the ultimate goal of maintaining patient safety and improving the quality of care.

The following is only a detailed description with specific embodiments and drawings, so that your reviewer can have a better understanding and understanding of the functions and features of the present invention.

Please refer to FIG. 1 to FIG. 4, the present invention includes a lock box 10. The following will explain in detail:

The lock box 10 is used for accommodating an infusion flow rate push-wheel adjuster 90. The lock box 10 includes a first cover 11 and a second cover 12. The first cover 11 and the second cover 12 are In a pivotally movable shape, the first cover 11 has an elastic plate 13 on one side of the inner wall, and the elastic plate 13 has a snap hole 14. The second cover 12 has two unlocking holes 15 on the surface corresponding to the elastic plate 13. The inner wall of the second cover body 12 has a locking portion 16 corresponding to the locking hole 14, and the locking portion 16 is used to be locked in the locking hole 14 to achieve the purpose of locking the lock box 10 and preventing it from opening.

In a structural embodiment, it further includes an unlocking member 20, the unlocking member 20 has two pins 21, used to penetrate the unlocking hole 15 into the lock box 10 to forcefully compress the elastic plate 13 and the card hole 14 to deform, and achieve the lock The box 10 is unlocked for the purpose of opening.

In a structural embodiment, the inner walls of the first cover 11 and the second cover 12 have two support plates 171, 172. The support plates 171, 172 are used to hold the infusion contained in the lock box 10 The flow rate push-wheel adjuster 90 achieves the purpose of fixing the infusion flow rate push-wheel adjuster 90 without loosening.

In a structural embodiment, the upper surface of the second cover 12 has a protrusion 18, which allows the upper side of the infusion flow rate push-wheel regulator 90 to protrude from the outer surface of the lock box 10 to be locked and positioned, thereby enhancing the infusion The flow rate push-wheel regulator 90 is fixed and will not loosen.

In a structural embodiment, the lock box 10 has two through slots 191, 192 on the upper and lower sides, and the infusion tube used for the infusion flow rate push wheel regulator 90 can penetrate from the lock box 10 through the through slots 191, 192 Out.

The foregoing is an introduction to the various components of the present invention and their composition methods, and then the use embodiments, features and benefits of the present invention are introduced as follows:

Please refer to Figure 4, Figure 5, Figure 6, and Figure 7, the infusion flow rate push wheel regulator 90 can be arranged in the open lock box 10, the first cover 11, the second cover After the bodies 12 are covered with each other, the supporting plates 171 and 172 support the infusion flow rate push-wheel regulator 90, and the protrusion 18 of the second cover body 12 is locked with the groove 91 of the infusion flow rate push-wheel regulator 90 The positioning makes the infusion flow rate push-wheel regulator 90 have the effect of being fixed and not loose.

As shown in FIG. 7, after the first cover body 11 and the second cover body 12 are closed with each other, the latching portion 16 is latched in the latching hole 14, so that the lock box 10 is locked and cannot be opened.

The present invention makes the infusion flow rate push-wheel regulator 90 locked in the lock box 10 by the locking action of the locking part 16 and the locking hole 14, and the lock box 10 cannot be opened manually, which can effectively fix the flow rate of the drip and effectively reduce Medical staff worry that patients or their caregivers may adjust the flow rate of the drip privately, which will affect the effectiveness of treatment, and cause serious complications, leading to medical disputes, and effectively reduce the number of nursing hours and medical manpower, so as to maintain patient safety and improve the quality of care Final goal.

Please refer to Figures 8 and 9, when you want to open the lock box 10 for observation or take out the infusion flow rate push-wheel regulator 90, you can align the pin 21 of the unlocking member 20 with the unlocking hole 15 and enter the lock box 10 in.

Please refer to Figure 10, Figure 11, Figure 12, the end of the pin 21 that enters the lock box 10 strongly presses the elastic plate 13 and the locking hole 14 is deformed, so that the locking portion 16 exits the locking hole. 14.
