Description

Venous transfusion speed fixer

Technical Field

The utility model relates to a medical device, in particular to a venous transfusion speed fixer.

Background

Intravenous infusion is a common administration mode in clinic, and the industrial standard of intravenous infusion treatment indicates that 80% of inpatients in China receive infusion treatment, each person in China infuses eight bottles of liquid per year in an intravenous manner, and 85% of nurses are used for infusion operation in more than 75% of working time. The intravenous infusion prescription indicated in the intravenous fluid treatment guideline of adults in hospitals should include the type of the infusion fluid, the infusion speed and the fluid amount, so that the correct adjustment of the infusion speed in the infusion process is the premise of effective treatment of the medicine, otherwise, the due effect cannot be achieved, the condition of the patient is deteriorated, and the life is threatened. Therefore, the effective control of the number of drops can directly relate to the treatment effect of patients, and the safety of clinical medication is improved.

At present, in clinical intravenous infusion treatment, disposable infusion sets are mostly used for intravenous infusion, and the control of the infusion drop number is to adjust a flow regulator on the disposable infusion sets and adjust the drop number according to the properties of infusion medicines, the medicine concentration, the age of patients, the illness state of the patients and the like. However, the flow rate regulator is designed by an open pulley, so that the flow rate regulator is convenient for nurses to operate, but is easy to regulate patients, and the condition that the treatment is affected by the regulation of the number of infusion drops by the patients often occurs. There is a great nursing safety risk. In clinical practice, a few departments also use a disposable flow setting fine adjustment type infusion apparatus for intravenous infusion therapy, the infusion apparatus is adjusted by a circular flow regulator, different flow scales are arranged around the regulator, and the number of infusion drops per minute is controlled by controlling the hourly flow. However, the flow control of the infusion apparatus cannot reflect the conditions of vascular pressure and vascular resistance, the condition that the set flow does not conform to the actual flow often occurs, and the cost is high, taking my hospital as an example: the disposable flow rate setting fine adjustment type infusion apparatus which is marked by the Fushan special medical catheter company Limited is 29 Yuan/Pao, and is not in the scope of medical social insurance reimbursement, so that the hospitalization cost of a patient is increased, and the disposable flow rate setting fine adjustment type infusion apparatus is difficult to popularize and use in clinic.

Disclosure of Invention

An object of the utility model is to provide a venous transfusion speed fixer to the problem of discovery in the clinical work, can fix the regulator of infusion speed, reduce patient's self-modulation probability, increase the security of vein medication, reduce the red light rate of infusion process.

The technical scheme of the utility model is that: the utility model provides a venous transfusion speed fixer, this fixer includes flow regulator and cavity flip, use conventional flow regulator on the transfusion system as the basis, thicken 1mm with the edge of flow regulator both sides and make one row of 1mm on both sides limit and multiply 1mm zigzag draw-in groove, cavity flip suits with the flow regulator size, cavity flip length is 0.5mm longer than the flow regulator, the width is 0.5mm than each width on flow regulator both sides, the height is 5mm, the nearly outside 1mm department in the interior limit of cavity flip both sides is equipped with an inside groove, a rectangular movable bayonet socket is done in the inside groove of both sides, the long limit of movable bayonet socket both sides is the same with the pulley diameter of flow regulator, the long limit height of both sides is 4mm, the width of movable bayonet socket is the same with the flow regulator, both sides broadside height is 5mm, the height of the same width of middle pulley is 7 mm.

A hasp is arranged at the middle point of the lower edge of the hollow flip cover, a button hole which is 3mm multiplied by 1mm is arranged in the hollow flip cover, a protrusion is arranged on the lower edge of the flow regulator, and the protrusion and the button hole on the flip cover can be mutually connected to form a son-mother relationship.

The utility model has the advantages that: the infusion speed can be effectively fixed, and the number of infusion drops can be correctly adjusted according to the pressure and the resistance of the blood vessel of a patient, so that the adjusted infusion speed is consistent with the actual infusion speed; the invention can effectively fix the transfusion speed, can not directly adjust the transfusion speed, and can effectively reduce the self-adjusting transfusion speed of the patient; the invention can effectively fix the transfusion speed, correctly calculate the transfusion time, reduce the empty bottle generation and the red light rate of the venous transfusion of the patient and improve the satisfaction degree of the patient; the flow regulator of the disposable infusion set is modified, the cost is low, and the treatment burden of a patient cannot be increased after the disposable infusion set is put into use.

Detailed Description

A venous transfusion speed fixer comprises a flow regulator 1 and a hollow turnover cover 2, based on a conventional flow regulator on an infusion apparatus, edges of two sides of the flow regulator are thickened by 1mm, a row of zigzag clamping grooves 3 which are 1mm multiplied by 1mm are formed in the edges of the two sides, a hollow flip cover 2 is adaptive to the size of the flow regulator 1, the length of the hollow flip cover 2 is 0.5mm longer than that of the flow regulator 1, the width of the hollow flip cover 2 is 0.5mm wider than that of the two sides of the flow regulator, the height of the hollow flip cover is 5mm, an inner groove 4 is formed in the position, close to the outer side by 1mm, of the inner edges of the two sides of the hollow flip cover 2, a rectangular movable bayonet 5 is formed in the inner grooves 4 of the two sides, the long sides of the movable bayonet 5 are the same as the diameter of a pulley 6 of the flow regulator, the long sides of the two sides are 4mm high, the width of the movable bayonet. A hasp is arranged at the middle point of the lower edge of the hollow turnover cover 2, a button hole 7 with the diameter of 3mm multiplied by 1mm is arranged in the hollow turnover cover, a protrusion 8 is arranged on the lower edge (the transfusion proximal end) of the flow regulator, and the protrusion and the button hole on the turnover cover can be mutually connected to form a son-mother relationship.

The technical route is as follows: lifting a turnover cover of a flow regulator on an infusion apparatus before intravenous infusion operation → opening and exhausting a pulley → sliding the pulley to the bottom to clamp an infusion tube after exhausting to carry out infusion according to the intravenous infusion flow → adjusting a pulley of the flow regulator according to factors such as illness state, age, liquid medicine property and the like after successful venipuncture → adjusting a bayonet in the turnover cover to the upper part of the pulley after correct drop adjustment → fixing the turnover cover, the fixed wheel replacement of the bayonet, and the upper wide edge and the lower wide edge of the bayonet with a clamping groove on the flow regulator to make the pulley immovable → buckling the button hole of the turnover cover on the protrusion of the flow regulator.

The flow regulator can be connected with the hollow turning cover in a mode that one end is fixed and the other end is turned up and then buckled, or in a mode that the turning cover is directly inserted and covered on the flow regulator.
