Heparin cap

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a heparin cap.

Background

The heparin cap is an indispensable apparatus in the clinical indwelling transfusion process as a commonly used medical apparatus, the traditional heparin cap is formed into a whole by a shell with a spiral connector and a rubber puncture piece, is connected with the connector of a transfusion pipeline in clinical use, and uses an injection puncture apparatus to puncture the rubber puncture piece to convey liquid medicine or extract body fluid such as blood. When the heparin cap is used clinically, the appearance of the catheter kept in the body of a patient can be closed to keep the inside of the catheter sterile, after each transfusion, a clinical nurse can use heparin sodium or normal saline to seal the kept catheter through the heparin cap, and then the water stop clamping piece is closed to prevent the blood of the patient from flowing back;

but current heparin cap does not possess the malleation function, leads to patient's daily motion to stop the water clamp not hard up, and venous pressure in the human body makes blood backward flow to the hose, has caused the blood backward flow, and heparin cap itself volume is less, because current heparin cap is cylindricly again for medical personnel easily appear the hand smooth phenomenon when dismantling, has increased the dismantlement speed, therefore we need provide a heparin cap.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a heparin cap, includes casing 1, and the one end of casing 1 is tubaeform setting, and through-hole 2 has been seted up to the center department of 1 one end of casing, through above-mentioned design, when the syringe need add the medicine to the heparin cap in, tubaeform through-hole 2 is convenient for the location of syringe.

Rubber packing 3 has been placed to casing 1's inside, and 1 inside below fixed mounting that is located rubber packing 3 of casing has first stopper 8, and the upper surface of first stopper 8 is hugged closely in the lower surface of rubber packing 3. Through the above design, first stopper 8 can be effectively spacing when the syringe passes rubber packing 3, makes rubber packing 3 can not the downstream reduce malleation space, and rubber packing 3 can effectively completely cut off the outside air and prevent that the gas in the heparin cap from leaking the inside pressure that influences the heparin cap.

The other end fixed mounting of casing 1 has connecting seat 4, and the outside of connecting seat 4 is provided with anti-skidding line, and thread groove 15 has been seted up to the inside of connecting seat 4, and the interior top fixed mounting of connecting seat 4 has sealing washer 16, through above-mentioned design, makes things convenient for connecting seat 4 and keeps somewhere the management system intercommunication each other, and when connecting seat 4 with when keeping somewhere the management system threaded connection, sealing washer 16 can contradict and improve the leakproofness between the two in the junction, avoids the production of the weeping condition.

The center of the connecting seat 4 is fixedly provided with a conical head inner cavity 5, the conical head inner cavity 5 is communicated with the shell 1, and the medicine in the positive pressure space can slowly flow into a retention management system communicated with the conical head inner cavity 5 through a crack formed on the rubber spacer 6.

Rubber spacer 6 has been placed with the inside of 4 fixed connection one ends of connecting seat to

casing

1, and 1 inside top fixed mounting that is located rubber spacer 6 of casing has second stopper 9, and the lower surface of second stopper 9 is hugged closely in the upper surface of rubber spacer 6, and through the aforesaid design, second stopper 9 is spacing with rubber spacer 6, prevents that 6 not hard up messenger's malleation spaces of rubber spacer from diminishing, leads to pressure unstability.

Through holes 10 are formed in the centers of the first limiting block 8 and the second limiting block 9, so that the medicine filled by the injector can flow into the conical head inner cavity 5 through the first limiting block 8 and the second limiting block 9.

The two sides of the shell 1 are respectively provided with an easy-to-pull assembly 7. Two sets of easy-to-draw subassemblies 7 all include two sets of fixing bases 11, arm-tie 12 and connecting rod 13, two sets of fixing bases 11 fixed mounting are in one side of casing 1, the one end and the connecting rod 13 fixed connection of arm-tie 12, the both ends of connecting rod 13 are rotated respectively and are installed on two sets of fixing bases 11, the top that the both sides of casing 1 lie in two sets of fixing bases 11 is fixed mounting respectively has third stopper 14, through the above-mentioned design, when medical personnel need take off the heparin cap, swivelling joint seat 4, make connecting seat 4 become flexible, then the arm-tie 12 on rotatory both sides, one side of arm-tie 12 is contradicted on third stopper 14, make arm-tie 12 on both sides tend to the parallelism, then use the finger to lift up and draw and can take off the heparin cap, the dismantlement difficulty that the smooth hand leads to has been avoided, the dismantlement efficiency is improved, and arm-tie 12 can rotate and pack up, be convenient for the installation of heparin cap to use fixes on the patient.

There are rubber packing 3 and rubber spacer 6 through at 1 inside interference fit of casing, make and form the malleation space between the two, when the syringe passed rubber packing 3 to malleation space and adds the medicine, because of having seted up the crack on the rubber spacer 6, the medicine slowly gets into conical head inner chamber 5 through the crack, at the in-process of adding the medicine, the malleation that forms in the malleation space is slowly reducing, make the malleation in the malleation space always be greater than the negative pressure that venous blood produced, effectively prevent the blood backward flow, cause the jam of infusion, and the venous infection that probably appears.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
