At present, in the process of percutaneous puncture for a patient, two steps of skin point scanning and positioning by an imaging device and percutaneous puncture are needed, in the first step, the skin puncture point scanned by the imaging device is positioned on the same body plane or forms a certain angle with a focus, but because the breathing depth of the patient in the two steps is different, in the operation process of the second step, the relative position between the skin puncture point selected in the first step and an actual focus is changed, so that the puncture success rate is reduced, and normal structures and tissues are damaged,
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, an object of the present invention is to provide a mask for assisted percutaneous puncture, which can keep the amount of inhaled gas of a patient in a relatively constant interval each time, so as to ensure that the relative positions of the skin puncture point and the lesion selected in the scanning step of the imaging device and the relative position of the skin puncture point and the lesion in the percutaneous puncture step do not change.
The mask for assisting percutaneous puncture comprises a mask body, wherein an air outlet and an air inlet are formed in the mask body, an air pressure detection device, an air flow meter and a single chip microcomputer are mounted on the mask body, and the output end of the air pressure detection device and the output end of the air flow meter are respectively connected with the signal input end of the single chip microcomputer; the air outlet and the air inlet are internally provided with a valve, and the control end of the valve is connected to the output end of the singlechip; the gas flow meter is respectively arranged at the gas outlet and the gas inlet.
The utility model provides a face guard has integrated atmospheric pressure detection device, gas flowmeter, singlechip and valve, atmospheric pressure and gas flow in gas detection device and the gas flowmeter collection face guard, and the valve is opened or is closed under the control of singlechip, has guaranteed that the patient inhales gas volume department every time in a relatively invariable interval, has guaranteed that image equipment scanning location step and percutaneous puncture step have the same degree of breathing, thereby improve the rate of accuracy of puncture focus and avoid haring normal tissue organ.
Further, the air pressure detection device is installed on the inner wall of the mask body. The air pressure condition in the mask can be better detected.
Furthermore, the display screen is connected with the signal output end of the single chip microcomputer. The patient can visually observe the air pressure condition and the air flow in the mask through the display screen so as to autonomously control the breathing depth.
Furthermore, a sealing ring is arranged on the edge of the mask body, which is in contact with the face. The sealing performance of the mask is improved.
The utility model has the advantages that: the mask ensures that the amount of gas inhaled by a patient is in a relatively constant interval every time, thereby ensuring the puncture success rate or the treatment effect. The leakproofness is good, can directly observe the atmospheric pressure condition and the gas flow in the face guard.
Drawings
Fig. 1 is a schematic structural view of a mask provided by the present invention;
in the figure: 1-mask body, 2-air outlet hole, 3-air inlet hole and 4-sealing ring.
Detailed Description
For better explanation of the claimed embodiments, the claimed embodiments will be described in further detail with reference to the accompanying drawings and detailed description.
The technical proposal required to be protected by the utility model is a mask for assisting percutaneous puncture, the structure of which is shown in figure 1. The mask comprises a mask body 1, wherein at least one air outlet 2 for discharging air and an air inlet 3 communicated with an oxygen cylinder through a hose are arranged on the mask body 1, an air pressure detection device for detecting the air pressure value in the mask, an air flow meter for detecting the air flow of the air inlet 3 and the air outlet 2 are arranged on the mask body 1, and the output end of the air pressure detection device and the output end of the air flow meter are respectively connected with the signal input end of the single chip; valves are arranged in the air outlet 2 and the air inlet 3, and control ends of the valves are connected to the output end of the single chip microcomputer; the gas flow meters are respectively arranged at the gas outlet hole 2 and the gas inlet hole 3. Wherein, the valves arranged in the air outlet 2 and the air inlet 3 are one-way valves.
Wherein, in order to detect the atmospheric pressure in the face guard better, atmospheric pressure detection device installs on the inner wall of face guard body 1, when the patient wears the face guard promptly, towards the one side of patient's face. The single chip microcomputer can be installed in any position of the mask body 1, such as on the surface of the mask body 1 or on the inner wall of the mask body 1, but is preferably installed in the mask body 1 (the space between the surface of the mask body 1 and the inner wall of the mask body 1), and the wires connecting the output end of the air pressure detection device and the output end of the air flow meter are not arranged in the mask body 1.
The principle of the mask is as follows: the percutaneous puncture operation technology has two steps in practical work, namely scanning and positioning by using an imaging device and selecting a proper puncture point on the skin, and percutaneous puncture. In actual work, the breathing depth of the first step is different from that of the second step due to the fact that a patient cannot well cooperate with breathing or due to factors such as mental stress, and the like, so that when the second step is used for percutaneous puncture, a puncture point, a needle inserting angle and depth which are positioned according to the first step cannot puncture a focus, and normal tissues and organs are damaged. The mask is used as an auxiliary device of a percutaneous puncture operation technology, and can enable a patient to independently observe the amount of inhaled gas, so that the same respiratory motility is ensured, and the puncture success rate is improved. The mask is provided with an air inlet hole and an air outlet hole, the air inlet hole is connected with oxygen, when a patient inhales air, the air inlet hole one-way valve device is opened, the air outlet hole one-way valve is closed, and air inflow is recorded; when a patient exhales, the one-way valve of the air outlet is opened, the one-way valve of the air inlet is closed, the air output is recorded, the air input and the air output are respectively set to be positive values and negative values, when a percutaneous puncture doctor orders the patient to inhale or exhale or directly hold the breath at each time, the patient can observe the sum of the air input and the air output on the display, so that the respiration is maintained at the same sum at each time, the respiratory degree is ensured to be consistent, the puncture success rate is improved, and the normal tissues and organs are prevented from being damaged.
In addition, the singlechip in this face guard still with the display screen. The data that atmospheric pressure detection device and gas flowmeter gathered are shown on the display screen, and this display screen is the LED display screen.
In order to improve the sealing performance of the mask, a sealing ring 4 is arranged on the edge of the mask body 1 contacting with the face.
The single chip microcomputer used in the mask is AT89C52, the air pressure detection device is an existing air pressure detector, and the air flowmeter is an existing air flowmeter.
