Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of venesection device.
Background technology
Polycythemia vera is hematology's disease, and the main pathophysiological basis of clinical manifestation is that blood (erythrocyte) total capacity increases, and blood viscosity increases, and causes whole body each internal organs slow blood flow and tissue ischemia.Headache, dizzy, tired, tinnitus, dim eyesight, similar neurosis symptom such as forgetful can appear in early days, acroanesthesia and twinge again later on, hyperhidrosis, visual disorder, skin pruritus and peptic ulcer.Seeing at most with hemorrhage, thrombosis and thromboembolism in the complication, often is underlying cause of death.This disease is if adopt Drug therapy, and onset is slow, weak effect.Venesection is the main treatment means of polycythemia vera.Therapeutic purposes are to make blood volume and red blood cell volume near normal as early as possible, suppress hemopoietic function of bone marrow, thereby mitigate the disease reduce complication.As do not have severe complication, and course of disease slower development, patient can survive more than the 10-15.The blood-letting of prior art medium-sized vein is to rely on the method for Blood Transfusion Department with the special collecting bag venous blood samples of donating blood, and mainly extracts venous blood out by the blood bag of a band vacuum.The heap(ed) capacity of each collecting bag of donating blood is 350ml, does not have scale, when donating blood with scale be placed on blood drawing bag below, when clinical usefulness is donated blood bag blood-letting then based on estimated weight, general each blood-letting requires between 200-400ml, because there is not scale, blood-letting amount accuracy rate is low; And do not have the actuator of control blood-letting speed, just piled the blood bag in 3-5 minute usually, cause untoward reaction.Blood Transfusion Department needs its know-how personnel to clinical manipulation with the blood-letting of blood sampling vacuum bag, and in addition, this collecting bag cost of donating blood is higher, increases patient's medical expense.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of easy and simple to handle, economic, effective, venesection device that cost is low.
In order to solve the problems of the technologies described above, this utility model provides a kind of venesection device, it is characterized in that, comprises pin, delivery conduit and the connection joint between described pin and delivery conduit, and the caliber internal diameter of described pin is 1.5-2mm.
The caliber external diameter of described pin is 2.0-2.2mm.
Described pin is a venous detaining needle.
Described pin is large size puncture needle or large size blood taking needle.
Described pin removably is arranged with the stylophore of belt lacing outward.
Also be provided with flow regulator on the described delivery conduit.
Described venesection device also comprises the container that can catch the band containing mark of the blood that described delivery conduit emits.
The container of described band containing mark is depleted infusion bottle.
Described delivery conduit length is more than or equal to 80cm.
Described delivery conduit length is 80-100cm.
Venesection device of the present utility model is simple in structure, existing blood exchange transfusion set's filtration fraction is cut off, the external depleted infusion bottle of that end of flow regulator, and venous detaining needle of this end connection of joint can be made, simple, quick and easy, economical, effective than vacuum blood bag depletion method, cost is low, patient and clinically all benefit.Further, the flow regulator that has control blood-letting speed on the delivery conduit can be controlled the blood-letting time and reach the blood-letting amount at 15-20 minute, reduces the untoward reaction that causes because of blood-letting is too fast greatly, the container of band containing mark is used for accepting the blood of emitting, and can accurately control the blood-letting amount.
Trial bleeding 24 examples are inferior clinically for venesection device of the present utility model, compare with 20 example time patients of vacuum venous blood collection bag blood-letting, relatively practicality, the safety of two kinds of blood-letting equipment blood-letting accuracys and clinical use, the result is: the donate blood blood-letting accuracy 0% of collecting bag of the blood-letting accuracy 100% of this venesection device, matched group; Use this venesection device to carry out blood-letting, untoward reaction takes place in none example, and carries out blood-letting with the collecting bag of donating blood, and untoward reaction 15% takes place.Venesection device nurse of the present utility model just can operate, and does not need the Blood Transfusion Department professional.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the three-dimensional profile sketch map of venesection device of the present utility model.
Fig. 2 is the perspective exploded view of venesection device part parts of the present utility model.
Fig. 3 is the another kind of user mode sketch map of venesection device of the present utility model.
The specific embodiment
Be the preferred venesection device of this utility model as Figure 1-3, form by the container 60 of pin 10, delivery conduit 20, joint 30, stylophore 40, flow regulator 50 and band containing mark.Easy structure is that the filtration fraction with existing blood exchange transfusion set cuts off, the external depleted infusion bottle of flow regulator 50 those ends, and this end of joint connects a venous detaining needle and gets final product.
Described pin 10 is preferably the PICC venous detaining needle shown in the figure, also can select large size puncture needle or large size blood taking needle for use, requirement to pin is that the caliber internal diameter is 1.5-2mm, be not easy the too greatly then big and aggravation patient pain of blood vessel wound surface of blood-letting success, internal diameter because internal diameter is too little, the caliber external diameter of pin can be 2.0-2.2mm.Described pin 10 is outer removably to be arranged with the stylophore 40 (consult illustrated in figures 1 and 2, same prior art) of belt lacing, and bigger if desired flow during blood-letting is directly received on the joint with stylophore after pin can being extracted out from stylophore, and state as shown in Figure 3.
This blood-letting device utilizes pressure differential to carry out blood-letting, and that end of pin need be than the high 80-100cm of infusion bottle, so, the length of described delivery conduit 20 is preferably 80-100cm more than or equal to 80cm, during the blood-letting operation, infusion bottle can be placed on the ground, sick bed can slightly raise, and just can emit blood.
