Abstract
The utility model discloses a medical instrument, in particular a piston type infusion set, which comprises a liquid medicine bottle, a liquid guide pipe and an air guide pipe, wherein the liquid medicine bottle is provided with a sealing cover; and the liquid guide pipe and the air guide pipe are connected with the sealing cover. The piston type infusion set is characterized by also comprising a piston sleeve, wherein the end part of the piston sleeve is connected with the liquid guide pipe and is also connected with an infusion pipe; the end part of the infusion pipe is provided with an infusion needle; a piston is arranged in the piston sleeve; the outer end of the piston is movably provided with a push rod; the push rod is in screwed connection with the piston sleeve; and the end part of the push rod is provided with a handle. Since the movement of the piston is realized in a spiral mode, the position of the piston does not change randomly, thereby guaranteeing the stability of the flow; the piston type infusion set is convenient to operate; and a patient can control the size of the flow extremely conveniently without calling a nurse.
Description
Technical field
This utility model is a kind of medical appliance, particularly a kind of piston type infusion set.
Background technology
When hospital carried out infusion treatment, its flow-control was to realize that through the mode of pushing specific practice is on infusion tube, to put a pressurizing unit, and when flexible pipe was not extruded, flow was maximum, and after extruding, flow just reduces.The defective of this extruding infusion set is an instability of flow, and patient's arm is moving a little, and some flow will great changes will take place, at this moment just must make the nurse adjust flow, so very bother.
Summary of the invention
The purpose of this utility model is in order to overcome the defective of extruding infusion set instability of flow, to invent a kind of piston type infusion set.
The purpose of this utility model realizes as follows: said piston type infusion set; Comprise medicinal liquid bottle, catheter and airway, the medicinal liquid bottle is provided with seal cover, and catheter is connected with seal cover with airway; It is characterized in that: also comprise a piston bush; The end of piston bush is connected with catheter, and the end of piston bush also is connected with tube for transfusion, and the end of tube for transfusion is provided with transfusion needle; Be provided with piston in the piston bush, the active push rod that is provided with in the outer end of piston, push rod and piston bush are spirally connected, and the end of push rod is provided with handle.
The good effect of this utility model is following: realize because piston mobile is form through spiral, so position of piston can not change arbitrarily, thereby guaranteed the stable of flow; And be convenient to operation; Patient need not call the nurse, and the own size that just can control flow is very convenient.
Description of drawings
Fig. 1 is this utility model structure chart.
Among the figure: 1 is the medicinal liquid bottle; 2 is catheter; 3 is airway;
4 is seal cover; 5 is piston bush; 6 is tube for transfusion;
7 is transfusion needle; 8 is piston; 9 is push rod;
10 handles.
The specific embodiment
As shown in Figure 1, said piston type infusion set comprises medicinal liquid bottle 1, catheter 2 and airway 3; Medicinal liquid bottle 1 is provided with seal cover 4; Catheter 2 is connected with seal cover 4 with airway 3, it is characterized in that: also comprise a piston bush 5, the end of piston bush 5 is connected with catheter 2; The end of piston bush 5 also is connected with tube for transfusion 6, and the end of tube for transfusion 6 is provided with transfusion needle 7; Be provided with piston 8 in the piston bush 5, the active push rod 9 that is provided with in the outer end of piston 8, push rod 9 is spirally connected with piston bush 5, and the end of push rod 9 is provided with handle 10.
During use, the medicinal liquid bottle is hung by the feet on transfusion stand, again catheter and airway are connected (before the use with seal cover on the medicinal liquid bottle; Catheter and airway are what to separate with the medicinal liquid bottle); Through rotary handle piston is moved around, size that just can the control piston sleeving inner space, the space in piston bush is hour; Flow is just little, otherwise flow is just big.
