The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The syringe 1, pressure sensor 2, hemostix 3, three-way valve 4, two-way valve 5, one-way valve 6, perfusion apparatus 7, perfusion clamp 8, catheter 9, protective sheath 10, blood sampling seat 11, silica gel pad 12, fixing plate 13, plug 14 and dropping funnel 15 parts of this application are all universal standard parts or parts known by technical personnel in the field, and the structure and principle thereof are all known by technical manuals or conventional experimental methods.
Referring to fig. 1, a closed invasive blood pressure monitoring device with blood sampling function comprises injectors 1, pressure sensors 2, blood sampling devices 3, syringes 7, plugs 14, a dropping funnel 15, a storage box, a cover plate movably connected to the top of the storage box through hinges, rubber plates arranged on the inner sides of the cover plate and the storage box, two injectors 1 connected with each other through a conduit 9 and a three-way valve 4, and a protective sleeve 10 sleeved on the bottom of each injector 1 to effectively avoid the related pollution caused by the push rod of the injector 1 pulling out the inner cavity, a two-way valve 5 and a pressure sensor 2 respectively connected to the top of the injector 1 and the three-way valve 4 through the conduit 9, a fixing plate 13 sleeved on the top of the injector 1 and the outer surface of the pressure sensor 2, and the conduit 9 connected between the pressure sensor 2 and the injector 1, the outer surface of the pressure sensor 2 is also provided with a one-way valve 6, meanwhile, the position of a conduit 9 communicated with the syringe 7 is provided with a perfusion clamp 8, the other interface of the two-way valve 5 is communicated with the blood sampler 3 through the conduit 9, the bottom of the blood sampler 3 is provided with a blood sampling seat 11, the outer surface of the blood sampling seat 11 is provided with a silica gel pad 12, the bottom of the pressure sensor 2 is respectively communicated with a plug 14 and the syringe 7 through the conduit 9, the pressure sensor 2 closed in vitro is used for sampling blood, the pain of a patient caused by additionally puncturing and sampling blood can be effectively reduced, the possibility of infection is reduced to the minimum, meanwhile, other channels are closed in the blood sampling process, after the blood is pumped through the syringe 1, when people collect the blood in the blood sampler 3, the liquid injected from the syringe 7 can be prevented from being sucked while collecting the blood, and then the syringe 1 is used for pushing back the sucked blood after the blood sampling, thereby avoid the patient excessive blood loss, at this in-process, people still can adjust the perfusate velocity of flow through perfusion ware 7 and perfusion clamp 8, and the right side of perfusion ware 7 has drip chamber 15 through pipe 9 intercommunication.
When the device is used, the pressure sensor 2 which is sealed outside the body is used for sampling and blood sampling, the pain of a patient caused by additionally puncturing and blood sampling can be effectively reduced, the possibility of infection is reduced to the minimum, meanwhile, in the blood sampling process, other channels are closed, after blood is sucked through the injector 1, when people collect the blood in the hemostix 3, the liquid injected from the syringe 7 can be prevented from being sucked while the blood is collected, the injector 1 is used for pushing back the sucked blood after blood sampling, so that excessive blood loss of the patient is avoided, in the process, people can also adjust the flow rate of the perfusion liquid through the syringe 7 and the perfusion clamp 8, when the device monitors blood pressure, all the connected through valves are kept open, the liquid is injected into the device through the syringe 7 and the perfusion clamp 8, when the cavity of the pressure sensor 2 is filled with the liquid, the blood vessel of a human body is connected, the fluid has a pressure transmission effect, the pressure of the liquid is sensed through an induction chip in the fluid, the pressure is converted into an electric signal, and measurement data are obtained through an external indicating device, so that the blood pressure value is monitored; when the device collects blood, the three-way valve 4 of the channel between the injector 1 and the pressure sensor 2 is closed, after the injector 1 sucks the blood, the blood sampling is carried out by puncturing the inner cavity of the hemostix 3 by using a blood sampling needle, after the blood collection is finished, the injector 1 is pushed back by the push rod, redundant blood is re-transfused to a patient, the phenomenon of anemia is avoided, finally, the through valve between the injector 1 and the pressure sensor 2 is communicated again, the blood pressure detection can be carried out continuously, the device can provide continuous, reliable and accurate monitoring data, compared with the existing pressure sensor 2 with the blood sampling function, the device has the advantages of convenient blood drawing, sealing and push-back function, can effectively prevent bleeding, embolism, infection and other complications during the blood collection, and adopts the protective sleeve 10 to form a completely sealed blood drawing device, so that the blood drawn back can be safely protected, and the blood is pushed back to the human body after sampling is finished, so that the blood drawing amount of clinical patients during repeated sampling is reduced, and the method has important significance for preventing anemia possibly caused by frequent blood drawing of the patients.
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.
