Abstract
The invention discloses a needleless barotropic medicine-adding infusion connector. The connector comprises a shell and a hollow sealing part, wherein the inside of the shell is provided with a through-hole; and the shape of the hollow sealing part is matched with that of the through-hole of the shell and embedded in the through-hole. The connector overcomes the defect that when the existing intravenous needle and transfusion needle are used in venipuncture for blood transfusion and infusion or medicine injection treatment of the patient, repeated punctures for infusion may be performed for long time or liquid medicine is added temporarily many times in each infusion so as to cause unnecessary pains on the patient. The product of the invention ensures the infusion device and the infusion connector to be connected firmly, reduces or avoids the pains of the patient and is extremely beneficial for eliminating medical negligences. The infusion connector of the invention is a infusion connector not using a needle and can be widely used in the clinical infusions of central venous catheter, peripheral intervention central venous and the like in the aspect of medical treatments.
Description
One, technical field
The present invention relates to a kind of infusion connector, particularly a kind of for medical aspect, can guarantee the Needleless barotropic medicine-adding infusion connector that infusion set and infusion connector are connected firmly.
Two, background technology
At present, in medical treatment is clinical, by venipuncture transfuse blood, transfusion or drug injection are modal method in the treatment patient process.Yet, existing medical personnel are carrying out to the patient in the treatment of venipuncture blood transfusion, transfusion or drug injection, be generally intravenous needle, transfusion needle puncture, because the various diseases situation is different or be subjected to the restriction of the condition of patient own, prolonged and repeated repeatedly puncture transfusion needing can occur or in the single transfusion, will repeatedly add the situation of injecting medical liquid in liquid-transport pipe-line temporarily, thereby bring unnecessary misery to the patient.
Three, summary of the invention
The objective of the invention is to provide a kind of infusion connector, a kind of Needleless barotropic medicine-adding infusion connector that can guarantee that infusion set and infusion connector are connected firmly particularly, with overcome existing intravenous needle, transfusion needle is carrying out the patient in the treatment of venipuncture blood transfusion, transfusion or drug injection, may need prolonged and repeated repeatedly puncture transfusion or in the single transfusion, will repeatedly add injecting medical liquid temporarily, bring the defective of unnecessary misery to the patient.
The object of the present invention is achieved like this: Needleless barotropic medicine-adding infusion connector of the present invention is comprised of housing and hollow sealing spare, a through hole is arranged in the described housing, this through hole is that the cone shape through hole reaches connect therewith upper by the middle part, lower cylindrical through hole consists of, described hollow sealing spare is by middle part cone and coupled upper, lower locating dowel consists of, and each is designed with respectively on one at least in the cone side at described hollow sealing spare middle part and near the circular cone bottom part, lower reinforcement, the profile of described hollow sealing spare and the through hole of described housing are complementary, and it is embedded in this through hole.
The present invention can guarantee that infusion set and infusion connector are connected firmly, and can reduce and avoid the patient suffering, can effectively avoid the non-artificial viral and pathogenic cross infection that causes, and has the meaning that is highly profitable to stopping malpractice.It is simple in structure, and is easy to operate, safe and reliable, and production cost is low.Simultaneously, it is a kind of infusion connector of exempting from pin operation, can be widely used in the clinical center venous duct in aspect medical and periphery gets involved the transfusions such as central vein.
Four, description of drawings
Fig. 1, be the structural representation that proposes according to the present invention;
Fig. 2, be the schematic perspective view of hollow sealing spare mentioned among the present invention;
Fig. 3, be the structural representation of hollow sealing spare mentioned among the present invention.
Five, the specific embodiment
Below in conjunction with drawings and Examples structure of the present invention is further described:
Labelling among the figure: 1, housing; 2, hollow sealing spare; 2-1, upper locating dowel; 2-2, upper reinforcement; 2-3, lower reinforcement; 2-4, lower locating dowel.
In the drawings, Needleless barotropic medicine-adding infusion connector of the present invention is comprised of housing 1 and hollow sealing spare 2, a through hole is arranged in the described housing 1, this through hole is that the cone shape through hole reaches connect therewith upper by the middle part, lower cylindrical through hole consists of, described hollow sealing spare 2 is by middle part cone and coupled upper, lower locating dowel 2-1,2-4 consists of, and each is designed with respectively on one at least in the cone side at described hollow sealing spare 2 middle parts and near the circular cone bottom part, lower reinforcement 2-2,2-3, the through hole of the profile of described hollow sealing spare 2 and described housing 1 is complementary, and it is embedded in this through hole.
In actual applications, with transfusion, the upper locating dowel 2-1 compression hollow sealing spare 2 of syringe conehead by playing the role of positioning among the present invention, make the certain gap of formation between sky sealing member 2 and the housing 1, medicinal liquid is just in this gap enters into patient body; When medical personnel to patient transfusion, inject or add injecting medical liquid complete after, pull out transfusion, syringe conehead, at this moment, described hollow sealing spare 2 resets because of the rapid resilience of upper and lower reinforcement 2-2,2-3 that design has had rebound effect, simultaneously, the present invention produces malleation, and the liquid that order is failed sprays to intravenous needle, transfusion needle, can avoid blood to reflux from intravenous needle, transfusion needle, thereby prevent blood coagulation, stop to produce thrombosis, like this, just without anticoagulant.
Wherein, above mentioned hollow sealing spare 2 by injection mo(u)lding, the intermediate portion is divided into hollow core structures.
Above-described only is preferential embodiment of the present invention.Should be pointed out that to those skilled in the art under the prerequisite that does not break away from the principle of the invention, can also make some modification and improvement, this also is considered as belonging to protection scope of the present invention.For example, described upper reinforcement 2-2, lower reinforcement 2-3 can be designed with respectively some reinforcements; In addition, as long as can satisfy result of use and guarantee under the prerequisite of application performance that the present invention can arrange reinforcement 2-2 and lower reinforcement 2-3 simultaneously, reinforcement 2-2 or lower reinforcement 2-3 can be set separately respectively also.
Claims (2)
1. Needleless barotropic medicine-adding infusion connector, formed by housing (1) and hollow sealing spare (2), it is characterized in that: a through hole is arranged in the described housing (1), this through hole is that the cone shape through hole reaches connect therewith upper by the middle part, lower cylindrical through hole consists of, described hollow sealing spare (2) is by middle part cone and coupled upper, lower locating dowel (2-1,2-4) consist of, and each is designed with respectively on one at least in the cone side at described hollow sealing spare (2) middle part and near the circular cone bottom part, lower reinforcement (2-2,2-3), the through hole of the profile of described hollow sealing spare (2) and described housing (1) is complementary, and it is embedded in this through hole.
