Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1-5, a novel infusion port comprises an injection seat 1, wherein the injection seat 1 is an injection seat 1 conventionally used in the existing infusion port, and the main structure of the injection seat 1 comprises a body of the injection seat 1 and a reservoir arranged in the injection seat 1, a top diaphragm 11 is fixedly connected to the top of the reservoir, and the reservoir is sealed by the top diaphragm 11.
The specific structure and operation principle of the injection seat 1 disclosed in the present invention can be known to those skilled in the art by referring to the technical manual or dictionary. The utility model discloses an improvement point lies in:
the bottom of the top diaphragm 11 is fixedly connected with a plurality of latex heads 111 (the latex nipple 111 is made of latex and has certain elasticity), a cavity is formed in the latex nipple 111, and the top of the latex heads 111 is open; the top of the nipple 111 is integrally formed with the bottom of the top membrane 11. The nipples 111 are annularly distributed on the top membrane 11. The nipple 111 is shaped as follows:
the nipple 111 includes a cylindrical portion 1111, an elliptical portion 1112 (elliptical in shape); a cylindrical portion 1111 is attached to the top diaphragm 11, and an elliptical portion 1112 is integrally formed with the cylindrical portion 1111.
According to the prior art, a mark corresponding to the latex head 111 is provided on the top of the top membrane 11, and the mark may be a circular mark (not shown), and when injecting the liquid medicine, first, the needle vertically penetrates the top membrane 11 downward from the circular mark, and under the guidance of the circular mark, the needle enters the cavity in the latex head 111, and penetrates the oval portion 1112, and then enters the reservoir to release the liquid medicine.
In actual work, in order to reduce replacement of the injection seat 1, the liquid storage tank is fixedly connected with an intermediate diaphragm 12, and the liquid storage tank is divided into an upper liquid tank A and a lower liquid tank B by the intermediate diaphragm 12 from top to bottom; the rubber nipple 111 is positioned in the upper liquid groove A (the bottom of the rubber nipple 111 and the bottom of the upper liquid groove A are arranged at intervals).
Meanwhile, the volume of the cavity of the lower liquid tank B is 1.5 times that of the cavity of the upper liquid tank A, and the middle diaphragm 12 and the top diaphragm 11 are made of the same material (the middle diaphragm 12 is made of a material capable of containing liquid medicine in the existing medical appliance, such as a corrosion-resistant latex material, has certain elasticity and corrosion resistance, cannot pollute the liquid medicine, and meanwhile, during infusion, less liquid medicine is retained in the upper liquid tank A, and the liquid medicine is continuously discharged).
The upper liquid tank A and the lower liquid tank B discharge liquid medicine according to the following modes:
the lower liquid tank B is communicated with a liquid discharge pipe 21, the liquid inlet end of the liquid discharge pipe 21 is communicated with the lower end in the lower liquid tank B, and the liquid outlet end of the liquid discharge pipe 21 is communicated with a transfusion hose 22.
Correspondingly, the upper liquid tank A is communicated with a liquid outlet hose 23, the liquid inlet end of the liquid outlet hose 23 is communicated with the lower end in the upper liquid tank A, and the liquid outlet end of the liquid outlet hose 23 is communicated with a transfusion hose 22.
The working principle and the process are as follows:
first, a liquid medicine is injected through the intravenous drip tube, the top diaphragm 11 is vertically pierced downward at the circular mark by the needle, the needle enters the cavity in the latex head 111 under the guidance of the circular mark, and then enters the upper liquid tank a after piercing the elliptical portion 1112, and the liquid medicine is released. The liquid medicine enters the human body from the liquid outlet hose 23-the transfusion hose 22.
Because the needle can be pricked into the latex head 111 each time under the guidance of the circular mark, and the latex nipple 111 has better elasticity, the latex head 111 can still keep certain tightness after being punctured for many times. Meanwhile, under the guidance of the round mark, the defect that the sealing performance of the top diaphragm 11 is reduced due to the fact that the top diaphragm 11 is punctured in a large area in the conventional mode is overcome.
Since the oval portion 1112 of the nipple 111 has a preferable surface tension, it is not easy to reduce the sealing property. At the same time, the tightness of the entire reservoir is again improved under the protection (sealing) of the latex head 111 and the top membrane 11.
After the puncture needle punctures the middle diaphragm 12, the liquid medicine is pumped into the lower liquid tank B and is discharged through the liquid discharge pipe 21 and the transfusion hose 22. The mode can realize the separate delivery of two different liquid medicines.
The device has the advantages of component design:
firstly, the liquid medicine is input through the intravenous drip tube by the top diaphragm 11 (the top of the top diaphragm 11 is provided with a circular mark) and the latex head 111, the top diaphragm 11 is vertically downwards punctured by the needle head on the circular mark, under the guidance of the circular mark, the needle head enters the cavity in the latex head 111 and punctures the oval part 1112, and then enters the upper liquid groove A to release the liquid medicine. The liquid medicine enters the human body from the liquid outlet hose 23-the transfusion hose 22.
Moreover, the needle can be inserted into the latex head 111 each time under the guidance of the circular mark, and the latex nipple 111 has good elasticity, so that the latex head 111 can still maintain certain tightness after being punctured for many times. Meanwhile, under the guidance of the circular mark, the defect that the sealing performance of the top diaphragm 11 is reduced due to the fact that the top diaphragm 11 is punctured in a large area in the conventional mode is overcome.
Secondly, the design of the middle diaphragm 12 firstly divides the liquid storage tank into an upper liquid tank A and a lower liquid tank B, so that after the puncture needle punctures the middle diaphragm 12, the liquid medicine is pumped into the lower liquid tank B and is discharged through a liquid discharge pipe 21 and a transfusion hose 22. The mode can realize the separate delivery of two different liquid medicines.
Through above-mentioned device part, not only effectively improved the life of infusion port, reduced the possibility that the infusion port was changed in the patient operation, simultaneously, reduced patient's treatment cost. The device effectively increases the sealing performance of the injection seat 1, ensures the cleanness of the injection seat 1 and improves the safety of treatment and use.
The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model. The protection scope of the present invention is subject to the claims.
