In order to further describe the technical means and effects adopted for achieving the preset aim of the present invention, the following detailed description refers to the specific implementation, structure, characteristics and effects of the simple gastric juice PH measuring device for digestive tract hemorrhage according to the present invention with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1 to 7, a simple gastric juice PH measuring apparatus for digestive tract hemorrhage according to the present invention,
Comprising a measurement base 10 and a measurement assembly 20;
The measuring base 10 consists of an empty syringe 12 with a liquid inlet 11 at the front end and a piston part 13 arranged in the empty syringe;
The measuring assembly 20 comprises a measuring cylinder 21, a PH test paper 22 and a contrast color card 23, wherein the PH test paper 22 is arranged in the measuring cylinder 21;
the measuring cylinder 21 slides back and forth in the hollow cavity of the piston part 13, and a groove body for the measuring cylinder 21 to pass through is arranged on the rubber stopper 131 of the piston part 13.
The embodiment of the application relates to a simple gastric juice PH value measuring device special for digestive tract hemorrhage, which is used in the using process:
the medical staff firstly takes out the measuring device, after checking that the connection is correct, firstly holds the push handle 133 of the empty syringe 12 and pumps gastric juice to be measured into the empty syringe 12; then, the medical staff holds the holding part 213 of the measuring cylinder 21, rotates the measuring cylinder 21 forwards, makes the measuring cylinder 21 pass through the accommodating groove 134 on the rubber plug 131 and penetrate the easy perforation 136 on the sealing film 135 to contact the gastric juice, and after the PH test paper 22 contacts the gastric juice, the medical staff can stretch out the measuring cylinder 21 to return to the original position; the medical staff can quickly compare the color of the PH test paper 22 with the color of the contrast color card 23 by observing the color change of the PH test paper, thereby quickly reading the PH value of the gastric juice.
It should be further noted that, the device is only used for measuring the PH value of gastric acid, so that the amount of gastric fluid to be collected is small, and the empty syringe 12 has a volume of 5ml, so that the gastric fluid measurement function can be realized;
meanwhile, the measuring device is disposable, has a simple structure, can read out a result by only collecting and measuring, and can be widely applied to the medical field.
As shown in fig. 2, 4, 6 and 7, the piston part 13 of the simple gastric juice PH measuring device for digestive tract hemorrhage according to the present invention is composed of a rubber stopper 131, a piston rod 132 and a push handle 133; the piston rod 132 is hollow, and the inside of the piston rod is used for accommodating the measuring assembly 20; a receiving groove 134 is formed in the center of the rubber stopper 131, and the receiving groove 134 is used for receiving the receiving cylinder 211 of the measuring cylinder 21; a sealing film 135 is arranged on the side wall of one end of the rubber plug 131 far away from the piston rod 132; the center of the sealing film 135 is provided with an easy-to-pierce hole 136 corresponding to the accommodating groove 134.
According to the simple gastric juice PH value measuring device special for gastrointestinal hemorrhage, the design of the piston part 13 is not only required to ensure the tightness of a gastric juice detection sample, but also required to enable the measuring cylinder 21 to pass through so that the PH test paper 22 contacts gastric juice to be detected;
A receiving groove 134 is formed in the top surface of the rubber stopper 131, which is close to one end of the measuring cylinder 21, i.e., the right end of the rubber stopper, the receiving groove 134 is used for the measuring cylinder 21 to pass through and is screwed with the measuring cylinder 21 through threads; when the user pushes the measuring cylinder 21 forward, the user needs to rotate to push the measuring cylinder 21 into the accommodating groove 134 of the rubber stopper 131 with force, and the front end of the measuring cylinder 21 can be pushed out from the slit 137 at the front end of the measuring cylinder to be soaked in gastric juice; gastric juice quickly infiltrates the PH paper 22 from the screen 215 at the left end of the measuring cylinder 21; after the PH test paper 22 is soaked, the measuring cylinder 21 is pulled out to return to the original position; at this time, the slit 137 at the front end of the rubber stopper 131 can be rapidly closed to prevent gastric juice from passing through the rubber stopper 131;
A sealing film 135 is arranged on the side wall of one end of the rubber plug 131 far away from the piston rod 132, and the sealing film 135 can keep the vacuum state in the empty syringe 12 to ensure the normal pumping operation of gastric juice when gastric juice is collected; after the front end of the measuring cylinder 21 pierces the easy-to-pierce hole 136 on the sealing film 135, a slit 137 is formed at the left end of the rubber stopper 131 to prevent liquid from flowing backward, the diameter of the slit is small for the conical measuring cylinder 21 to pass through, and after the measuring cylinder 21 is pulled away, the slit can be quickly returned to avoid gastric juice from passing through the accommodating groove 134 due to the material of the rubber stopper 131;
It should be noted that, the easy-to-pierce hole 136 is disposed at the center of the sealing film 135, so that the cone-shaped measuring cylinder 21 can pass through quickly; the sealing film 135 is made of plastic film, which only has the purpose of sealing, and the material is safe, and the PH measurement of gastric juice is not good.
As shown in fig. 2 and 4, in the simple gastric juice PH measuring device special for digestive tract hemorrhage according to the present invention, the top end of the accommodating groove 134 is flush with one end of the rubber stopper 131 close to the piston rod 132, and the other end is spaced apart from the outer wall of the rubber stopper 131 by a distance of 5 mm; the receiving groove 134 is provided with a slit 137 from the outer wall of the rubber stopper 131.
The embodiment of the application provides a simple gastric juice PH measuring device special for gastrointestinal hemorrhage, wherein a slit 137 is arranged at the front end of a containing groove 134, the slit 137 can be used for the front end of a conical measuring cylinder 21 to pass through, and the measuring cylinder 21 can be ensured to be quickly closed after being pulled away to prevent gastric juice from passing through the rubber plug 131 in a countercurrent manner.
As shown in fig. 3, the measuring cylinder 21 of the simple gastric juice PH measuring device special for digestive tract hemorrhage according to the present invention is composed of a holding cylinder 211, a connecting rod 212 and a hand-held part 213 provided at the rear end thereof; an external thread 214 matched with the internal thread 138 on the inner wall of the accommodating groove 134 is arranged on the left end outer side wall of the accommodating cylinder 211; the left end of the accommodating cylinder 211 is provided with a filter screen 215, and a PH test paper 22 is laid in the hollow cavity of the accommodating cylinder 211.
