Description
Technical Field
The utility model relates to a seal tub technical field behind the infusion especially relates to a disposable pre-filling formula tube clipper.
Background
The infusion by placing a liquid catheter in a blood vessel of a human body is a common disease treatment mode. When the input liquid is less in variety, the infusion apparatus is directly connected with the liquid catheter; when the types of the input liquid are more, a medical tee joint can be arranged so as to be connected with more infusion sets.
After transfusion, in order to avoid the blood from entering the liquid conduit and blocking the liquid conduit after blood coagulation, a tube sealing is needed. The tube sealing is actually injecting a tube sealing liquid (such as physiological saline) into the liquid catheter. Taking the situation of setting a medical tee as an example, the tube sealing mode commonly adopted by hospitals at present is to use an injector to extract tube sealing liquid, then to make the nipple of the injector abut against the joint of the medical tee, and then to inject the tube sealing liquid into a liquid conduit; if the medical tee joint is connected with a heparin cap, the needle head of the injector can be pricked into the heparin cap, and then the tube sealing liquid is injected into the liquid catheter. In the method, the tube sealing liquid needs to be extracted by an injector, so the operation is more complicated; the syringe is discarded after the tube is sealed, and the cost is higher.
To simplify the operation, a prefilled syringe with a tube sealing liquid is introduced. When the pipe is sealed, the pipe sealing liquid does not need to be extracted, so the operation can be simplified. For example, ZL201621247177.2, 201721626322.2 both disclose prefilled, sealed-tube syringes. Although the pre-filled tube-sealed injector can simplify the operation, the problem of higher cost still exists, and the economic burden of a patient is increased by one-time use.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1, the disposable prefilled tube sealing device comprises a joint 1, a flexible bag 2, a one-way valve 3 and a plug 4; the flexible bag 2 is connected with the rear end of the joint 1, and the flexible bag 2 is pre-filled with a tube sealing liquid 5; the front part of the joint 1 is provided with a connecting internal thread 11 and a connecting column 12 positioned in the center of the connecting internal thread 11, the joint 1 is provided with a liquid hole 13 and an air hole 14, the liquid hole 13 extends backwards from the front end of the connecting column 12 to be communicated with the flexible bag 2, and the air hole 14 extends from the surface of the connecting internal thread 11 to the surface of the joint 1; the one-way valve 3 is arranged in the liquid hole 13 and can be opened forwards in one way; the plug 4 is connected with the connecting internal thread 11 and plugs the liquid hole 13.
Taking the situation of setting a medical three-way valve 8 for transfusion as an example, as shown in fig. 3, the plug 4 is detached, the connector 1 is connected with the medical three-way valve 8, then the flexible bag 2 is squeezed, the one-way valve 3 is opened, and the tube sealing liquid 5 can enter the liquid conduit from the liquid hole 13 to realize tube sealing. When the medical three-way valve 8 is not arranged for transfusion, the connector 1 is directly connected with the liquid conduit, and other operation modes are the same.
The one-way valve 3 is a prior art valve, and is constructed as shown in fig. 1 and 2, and is a bullet-shaped cone structure with a notch, and the material of the one-way valve can be silica gel. The flexible bag 2 is extruded, the tube sealing liquid 5 can open the incision, and the one-way valve 3 is opened. If the tube sealing liquid 5 has a tendency of flowing in the reverse direction, the tube sealing liquid 5 can not prop open the incision and can close the incision more, so that the one-way valve 3 is opened in one way, and the backflow of the tube sealing liquid 5 can be avoided. When the plug 4 is detached to be connected with the medical tee joint 8, the one-way valve 3 can also prevent the tube sealing liquid 5 from leaking.
The plug 4 and the connecting internal thread 11 are obviously in threaded connection, and the threaded connection has a sealing effect; this allows internal gas to block the plug 4 from entering when the plug 4 is installed; when the plug 4 is detached, negative pressure is generated, so that the tube sealing liquid 5 is washed out. Therefore, the utility model is provided with the air hole 14, the air is exhausted when the plug 4 is installed, and the plug 4 can be installed smoothly; when the plug 4 is detached, air is introduced to avoid sucking out the tube sealing liquid 5 by negative pressure.
The shape and size of the connecting column 12 should match the shape and size of the inner bore of the medical tee 8 and the inner bore of the liquid conduit fitting, so that when the fitting 1 is connected, the connecting column 12 fits the inner bore of the medical tee 8, as shown in fig. 3.
In order to control the delivery rate of the catheter lock liquid 5, the liquid orifice 13 should be small, but too small a liquid orifice 13 may affect the setting of the one-way valve 3, because the one-way valve 3 is difficult to make extremely small. Therefore, the liquid hole 13 is preferably big in front and small in back, and the one-way valve 3 is arranged in front of the liquid hole 13. Thus, the above-mentioned contradiction can be solved.
The air hole 14 is a very small hole, so that external pollutants are difficult to enter the connector 1, and in order to further prevent the external pollutants from entering the connector 1, the disposable pre-filled tube sealing device comprises an air hole paste 6, and the air hole paste 6 is pasted on the connector 1 and seals the air hole 14. When the disposable prefilled tube sealing device is produced, the plug 4 is firstly installed, and then the air hole paste 6 is pasted. When the disposable prefilled tube sealing device is used, the air hole paste 6 is firstly removed.
The disposable prefilled tube sealing device is suitable for being directly connected with the medical tee 8 or the liquid catheter joint. In order to expand the application range of the present invention, as shown in fig. 4 and 5, the disposable prefilled tube sealing device includes a needle connector 7, the needle connector 7 includes a connector main body 71 and a puncture needle 72, the connector main body 71 can be connected with the connection internal thread 11; when the needle-attached connector 7 is connected to the female connection thread 11, the connector body 71 is fitted to the connection post 12, and the liquid hole 13 communicates with the puncture needle 72.
As shown in fig. 6, the puncture needle 72 can be inserted into the heparin cap 9 to seal the tube, and is suitable for sealing the tube when the heparin cap 9 is not removed and the medical tee 8 or the liquid conduit connector is connected with the heparin cap 9.
The needle connector 7 is an alternative component of the disposable pre-filling type tube sealing device, and can be selected to be connected with the joint 1 or not according to the situation, so that the application range of the utility model is widened.
In addition, in order to improve the sealing effect between the plug 4 and the pin connector 7 and the connecting column 12, a gasket may be provided on the plug 4 and the connector body 71, and the gasket may be attached to the end surface of the connecting column 12 to improve the sealing effect.
