Description
Technical field
The utility model relates to a kind of medical supplies more particularly to a kind of facilitate fixed positive pressure connector.
Background technique
The Preserving times such as remaining needle, central venous catheter, peripherally inserted central conduit and transfusion port are in blood of human body
The instrument of the circulatory system, can be carried out multiple dosing, avoid repeated puncture, reduces patient's pain and body injury, is the following infusion
The development trend for the treatment of.But after each infused, if directly pulling out needle tubing or conehead from indwelling instrument, it will be formed
Cavity leads to negative pressure, and blood backflow is caused to enter indwelling instrument, forms thrombus blocking, indwelling instrument is caused to scrap.
In this regard, care operation code requirement is wanted to inject when slowly pulling out needle when pulling out needle tubing, indwelling during needle is pulled out in holding
It is always positive pressure in instrument, avoids blood back, avoids blocking.And when pulling out conehead, due to loosening once retreating, it can not do at all
To slowly pulling out, positive pressure cannot keep, so, existing usual way is exactly in remaining needle, central venous catheter, through in periphery
The drug entering side of cardiac vein conduit and transfusion port etc. increases a positive pressure connector and occurs to avoid the phenomenon that blood back, still, positive pressure
Connector volume itself is bigger with respect to for perfusion tube, while lacking fixed device again, therefore, when patient activity,
It is scraped by other articles, such as clothing, sheet and other items it is possible that positive pressure connector can occur and then draws remaining needle, central vein
Conduit, peripherally inserted central conduit and transfusion port etc. shift, and cause remaining needle, central venous catheter, through in periphery
Cardiac vein conduit and transfusion port etc. next time infusion when can not reuse, therefore, be badly in need of it is a kind of can be convenient it is fixed just
Crimp head is above-mentioned to solve the problems, such as.
Utility model content
In view of the above-mentioned problems existing in the prior art, it is provided by the utility model it is a kind of facilitate fixed positive pressure connector,
It can not only prevent remaining needle, central venous catheter, peripherally inserted central conduit and transfusion port etc. from occurring when pulling out needle
Blood return phenomenon, while the cuff or collar mouth that positive pressure connector is fixed on to patient can also be facilitated, prevent from being scraped by other articles and
The hair for the problem of causing remaining needle, central venous catheter, peripherally inserted central conduit and transfusion port etc. that can not reuse
It is raw.
To realize that above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows:
It is a kind of to facilitate fixed positive pressure connector, including positive pressure connector ontology, the lateral wall of positive pressure connector ontology one end
On be provided with the sliding slot along the positive pressure connector body length direction, the sliding slot inner slidable to be provided with positive pressure connector solid
Fixed arm, the positive pressure connector fixed arm are in arc-shaped, and one end of the positive pressure connector fixed arm is provided with can be sliding with the sliding slot
The sliding block of dynamic connection, the other end are close to the lateral wall of the positive pressure connector ontology, and the positive pressure connector fixed arm integrally uses
Elastic material is made；When needing fixed positive pressure connector, one end that positive pressure connector fixed arm is not connect with sliding slot is lifted with hand,
And then the cuff of patient or collar mouth are placed between positive pressure connector ontology and positive pressure connector fixed arm, because positive pressure connector is fixed
Arm is made of elastic material, therefore, unclamps the finger for lifting positive pressure connector fixed arm, work of the positive pressure connector fixed arm in elastic force
With lower by the positive pressure connector ontology cuff for being clamped in patient or collar mouth tightly, prevent positive pressure connector from loosening.
In one of the embodiments, the end face of positive pressure connector ontology one end be located at the positive pressure connector ontology this
One end of the sliding slot at end is connected to, and the sliding block of the positive pressure connector fixed arm is by being located on described this end face of positive pressure connector ontology
Sliding slot port is slidably installed to the sliding slot, and it is solid to need replacing or be intended to recycling positive pressure connector in positive pressure connector damage
When fixed arm, positive pressure connector fixed arm can be slided into positive pressure connector fixed arm to the outlet end of sliding slot, it can be easily by positive pressure
Connector fixed arm disassembles, correspondingly, installation positive pressure connector fixed arm is also very easy and convenient.
The gap between the sliding block and the sliding slot is greater than zero in one of the embodiments, and less than 0.5 millimeter,
Guarantee between sliding block and sliding slot with clearance fit is combined into, while the installation both facilitated, sliding block will not easily from
It is slipped away in sliding slot.
In one of the embodiments, the inside of positive pressure connector fixed arm middle section be inlaid with shape and it is described just
The similar steel disc of crimp head fixed arm shape further improves the chucking power of positive pressure connector fixed arm, together by the way that steel disc is arranged
When also extend the service life of positive pressure connector fixed arm.
The end that the positive pressure connector fixed arm is close to the positive pressure connector outer body wall in one of the embodiments,
The first groove is provided on face, it is recessed that the position that the positive pressure connector ontology is close to the positive pressure connector fixed arm is provided with second
Slot, first groove and the second inside grooves pass through super glue respectively and are fixedly installed magnet, and it is recessed to be located at described first
Magnet in slot attracts each other with the magnet for being located at second inside grooves, by the way that magnet is arranged, on the one hand in positive pressure connector
Fixed arm will not cause to damage to the clothing of patient when in use, on the other hand, can more ensure that positive pressure connector is needing admittedly
Timing is not moved.
The thickness of the magnet is less than or equal to the depth of first groove in one of the embodiments, and described
First groove is identical as the depth of the second groove, avoids the prominent groove upper surface of magnet, further avoids in holding clothes pair
Clothing enters the obstruction of the generation of the region between positive pressure connector fixed arm and positive pressure connector ontology, and improve product uses body
It tests.
Compared with prior art,
1, it is provided by the utility model it is a kind of facilitate fixed positive pressure connector, remaining needle, central vein can not only be prevented
The blood return phenomenon that conduit, peripherally inserted central conduit and transfusion port etc. occur when pulling out needle, while can also facilitate positive pressure
Connector is fixed on the cuff or collar mouth of patient, prevents from being scraped by other articles and leads to remaining needle, central venous catheter, through outer
The generation for the problem of all central venous catheter and transfusion port etc. can not reuse.
2, positive pressure connector fixed arm and positive pressure connector ontology facilitate positive pressure connector solid using dismountable connection type is slided
The replacement of fixed arm reduces the use cost of product it is also possible to facilitate the recycling of positive pressure connector fixed arm, is conducive to subtract
The medical expense of few patient.
