Abstract
The utility model discloses a transfusion apparatus, which comprises an injection needle arranged at the tail end of a transfusion tube. A handle is fixedly arranged on the outer wall of the injection needle, a transparent tube is fixedly attached on the inner wall of the injection needle, and a strip-shaped window which extends along the length direction of the injection needle is arranged on the side wall of the injection needle. The transfusion tube which is close to the injection needle is serially connected with an elastic corrugated pipe. Protruded grains are uniformly distributed on the outer surface of the handle. The friction force of the surface of the handle can be strengthened, skidding can be avoided when a doctor holds the handle by the hands or the handle is fixedly adhered via adhesive tapes, and the transfusion apparatus is favorable for increasing transfusion quality. The transfusion apparatus with the structure is reasonable in structure, low in requirements to blood pressure, fast in blood return judgment and convenient in operation, is suitable for various venous transfusion places, is particularly suitable for venous transfusion of patients with lower blood pressure such as frail persons or infants and the like, and is favorable for increasing transfusion quality.
Description
Technical field
This utility model relates to a kind of transfusion device.
Background technology
Transfusion device is mainly used in the common disposable medical treatment consumptive materials process aseptic process, that set up passage between vein and the medicinal liquid of venous transfusion.Traditional transfusion device generally comprises tube for transfusion, be connected the entry needle of tube for transfusion end, be installed with handle on the entry needle outer wall, the tube for transfusion middle part is connected with liquid medicine filter, flow regulator, Mao Feishi dropper, and the tube for transfusion upper end is provided with bottle plug puncture unit and air inlet pipe air filter.The traditional infusion pipe in use, the general messenger drug liquid stream that earlier bottle plug puncture unit thrust in the infusion bottle is to entry needle, and close flow regulator, hold the entry needle handle then entry needle is thrust patient's intravenous, when the intravenous blood of patient is back to tube for transfusion when terminal by entry needle under blood pressure, the doctor just can judge successfully to be thrust the entry needle front end in the vein blood vessel, opens flow regulator at last and infuses and get final product.The traditional infusion device is simple in structure, and is easy to operate, uses very extensive clinically, weak point is, patient's blood pressure had relatively high expectations, and for physical weakness and infant patient, its blood pressure is lower, during venipuncture, venous blood is not enough to be back in the tube for transfusion, therefore often causes doctor's blood back to judge slow even erroneous judgement, so that implement repeatedly puncture, not only bring misery, also can cause huge mental pressure, be unfavorable for state of an illness rehabilitation to the patient.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of rational in infrastructure at above-mentioned deficiency, and is low to the blood pressure requirement, and blood back is judged fast, and easy to operate transfusion device.
For solving the problems of the technologies described above, this transfusion device comprises the entry needle that is connected the tube for transfusion end, be installed with handle on the entry needle outer wall, its construction features is: fixedly be adjacent to transparent tube on the entry needle inwall, the entry needle sidewall is provided with the marking shape window that extends along the entry needle length direction.
The transfusion device of this structure is to show the blood agglomeration structure by needle body to realize blood pressure is required low, and blood back judges fast, and easy to operate.
Needle body shows the blood agglomeration structure and mainly comprises the transparent tube that is arranged in the entry needle, and transparent tube outer wall and entry needle inwall closely are adjacent to together, like this, and transparent tube and the entry needle formula structure that just becomes one.The entry needle sidewall is provided with the window that is communicated with the needle body inside and outside wall, and window is elongated, extends along the entry needle length direction.See through window and can directly see transparent tube, because transparent tube is transparent, so, can see through transparent tube from window and observe situation in the transparent tube.When using this transfusion device to carry out the venipuncture transfusion, transparent tube can be thrust in the vein blood vessel with entry needle, and the blood in the vein blood vessel can flow to tube for transfusion by transparent tube.Even patient's blood pressure is lower, venous blood is not enough to enter tube for transfusion, but as long as blood enters transparent tube, the doctor just can see through transparent tube by the window on the entry needle and observe blood back in the shortest time, need not to wait for that blood is back in the tube for transfusion, not only saved the puncture time, and the blood back judgement is more accurate, also helps to improve venipuncture efficient.
As improvement, be in series with elastic bellows near on the tube for transfusion of entry needle.
The rubber-like corrugated tube is set on tube for transfusion, and in venipuncture blood back process, corrugated tube can discharge and cushion the pressure in the tube for transfusion, makes the easier entry needle that enters of venous blood, helps to improve blood back speed.
As further improvement, be evenly equipped with the burr of protrusion on the handle outer surface.
Burr is set on handle, can strengthens handle surfaces frictional force,, when still pasting fixed handle, skidding can not occur, help to improve injection quality with adhesive plaster no matter be doctor when controlling handle.
In sum, adopt the transfusion device of this structure, rational in infrastructure, require low to blood pressure, blood back is judged quick, and easy to operate, is adapted at various venous transfusion occasions and uses, use when especially being fit to, help to improve injection quality the lower patient's venous transfusion of blood pressures such as physical weakness or infant.
Description of drawings
In conjunction with the accompanying drawings this utility model is described in further details:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is tube for transfusion, and 2 is entry needle, and 3 is handle, and 4 is transparent tube, and 5 is window, and 6 is corrugated tube, and 7 is burr.
The specific embodiment
As shown in Figure 1, this transfusion device comprises tube for transfusion 1, and the liquid outlet of tube for transfusion 1 is sealedly connected with entry needle 2 by handle 3.Be provided with transparent tube 4 in the entry needle 2, transparent tube 4 is a pipe, and the outer wall of transparent tube 4 and entry needle 2 inner wall sealings are pressed together, transparent tube 4 and entry needle 2 structure that is connected to one.Entry needle 2 sidewalls are provided with window 5, and window 5 connects the entry needle inside and outside wall, and window 5 is elongated, along the length direction extension of entry needle 2.Can observe directly transparent tube 4 by window 5, see through transparent tube 4 and can observe medicinal liquid or blood in the transparent tube 4.When carrying out venipuncture, the blood that flows in the window 5 can be observed in advance by the doctor, and need not by the time, blood is back in the tube for transfusion 1, for the puncture blood back provides reliable basis for estimation, save the puncture time, reduced puncture time, helped to alleviate patient's misery and psychological burden.
Be in series with corrugated tube 6 near on the tube for transfusion 1 of entry needle 2, corrugated tube 6 has good telescopic resilience, and when the venipuncture blood back, corrugated tube 6 can provide competent blood back space for the vein blood back, has alleviated the buffer brake of blood back, helps to improve blood back speed.
Be evenly equipped with the burr 7 of outside protrusion on handle 3 outer surfaces, the main effect of burr 7 is the skin-friction forces that increase handle 3.When doctor's handle 3 dominated by hand, or when pasting handle 3 on the patient body, can prevent skidding, help to guarantee injection quality with adhesive plaster.
