Abstract
The utility model relates to an anti-drop transfusion apparatus, which comprises a bottom stopper puncturing member, an air intake member, a drip chamber, a flow regulator, a vein puncturing member and a connecting catheter for connecting the members; wherein, a fastening device is arranged at the joint where the end joint of the vein puncturing member is connected with the connecting catheter. In prior art, the ordinary transfusion apparatus is connected with the venous indwelling needle in a common inserting manner, and the catheter comes off easily; moreover, the joint is usually covered by clothes and difficult for medical staff to ascertain the situation in time, thus the patients are put under the dangers of huge blood loss, infection of germs, liquid medicine loss and even air embolism, resulting in greater hidden threats to the lives of the patients. By arranging a fastening device at the joint where the transfusion catheter is connected with the joint of the vein puncturing member, the utility model has the advantages that the catheter of the transfusion apparatus cannot come off the vein puncturing member retained inside the body of a patient, thus the safety of transfusion is enhanced.
Description
Technical field
This utility model relates to a kind of medical apparatus, particularly a kind of anticreep transfusion device.
Background technology
Venous transfusion is to utilize fluid pressure principle and atmospheric effect, and a large amount of sterile solutions or medicine are directly splashed into the venous method.Because venous transfusion absorbs soon, absorbs fully; can be used for a large amount of fluid infusion, blood transfusion or blood product, nutrient; sustainability is infused and is kept blood and want concentration again; and venous transfusion can reduce puncture time; the protection blood vessel, palliate the agonizing sufferings, thus venous transfusion be at present the most effective also be the mode of the most frequently used administration or nutrition.But splash in the process of human vein at the lower liquid of this temperature generally with the storing mode of cold preservation because the intravital liquid of input patient is previous, patient's general sensory health cold, in operation process, this seam is often covered by medicated clothing especially.The transfusion device commonly used at present and the interface of venous detaining needle are common inserting mode, be easy to break away from, and medicated clothing covers down, and medical personnel are difficult in time finding, so just cause a large amount of blood of patient from this seam loss, courses of infection, medicinal liquid loss even formation gas embolism, bring bigger hidden danger for patient's life security.
Summary of the invention
In order to overcome above-mentioned defective, this utility model provides a kind of anticreep transfusion device.
Anticreep transfusion device of the present utility model, comprise bottle stopper piercing assembly, air intake assembly, dropping funnel, flow regulator, venipuncture assembly and connect the connecting duct of above-mentioned each parts, the end connector of described venipuncture assembly and catheter adapter place have a bracing means.
In an embodiment of the present utility model, the bracing means of described venipuncture assembly and described catheter adapter place is the helicitic texture matable assembly.
In a specific embodiment of the present utility model, the bracing means of described catheter adapter place is a threaded nut in.
In another embodiment of the present utility model, described catheter adapter is connected with the end connector of described venipuncture assembly, and the screw thread that cooperates with the helicitic texture matable assembly of described catheter adapter place is arranged on the described end connector.
Go back among the embodiment preceding resistance head that described catheter adapter place cooperates with described nut in addition and back resistance head of the present utility model.
In another specific embodiment of the present utility model, also comprise air filter in the described air intake assembly.
In another specific embodiment of the present utility model, a liquid medicine filter was arranged before described catheter adapter.
Because transfusion device of the present utility model, junction at described catheter adapter and described venipuncture assembly joint is provided with a bracing means, so the conduit of described transfusion device just not can be retained in the intravital described venipuncture assembly of patient and come off, so just strengthened the safety of infusing.When transfusion device is subjected to big external force, can break away between transfusion device and the medicinal liquid bottle, alleviate external force and affact human body, avoid the disengaging of venipuncture assembly and human body, in order to avoid cause bigger damage.
Description of drawings
Fig. 1 is this utility model syringe sketch map.
Fig. 2 A is the catheter adapter enlarged diagram,
Fig. 2 B is that catheter adapter and venipuncture needle caudal knot close the state perspective view,
Fig. 3 is the catheter adapter and the venipuncture backshank joint sketch map of prior art.
The specific embodiment
As Fig. 1, Fig. 2 A, Fig. 2 B, anticreep transfusion device of the present utility model, the connecting duct that it comprises bottle stopper piercing assembly 10, air intake assembly 11, dropping funnel 12, flow regulator 13, venipuncture assembly 14 and connects above-mentioned each parts, described venipuncture assembly 14 has a bracing means 151 with catheter adapter 15 places.
As Fig. 2 A, Fig. 2 B, described venipuncture assembly 14 is a threaded nut in the bracing means 151 at described catheter adapter 15 places, and described catheter adapter 15 places cooperate with described bracing means 151 hinders 153 and preceding resistance 152 after also having.Described back resistance 153 can stop described nut 151 to slide backward along conduit, and the helicitic texture 141 that cooperates with described nut 151 is arranged on the end connector 142 of described venipuncture assembly 14.As Fig. 2 B, during use, the plug 154 of described catheter adapter 15 inserts in the described end connector 142 of described venipuncture assembly 14, rotate described nut 151 again, screw thread 156 and screw thread 141 threes in resistance 152 before described, the nut 151 cooperate, and make described catheter adapter 15 and described venipuncture assembly 14 strong bonded and do not come off.
Fig. 3 is the conduit and the venipuncture backshank joint sketch map of the transfusion device of prior art, this connected mode is common plug-in type, compare with transfusion device of the present utility model, transfusion device of the present utility model is provided with a bracing means in the junction of catheter adapter and venipuncture assembly joint, so the conduit of transfusion device just not can be retained in the intravital venipuncture assembly of patient and come off, so just strengthened the safety of infusing.
Above disclosed only is preferred embodiment of the present utility model, can not limit claim scope of the present utility model with this, according to the equivalent variations that explanation of the present utility model is made, still belongs to the scope of this utility model protection.
