Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a sample extraction device for medical examination. Background Technique

[0002] With the development of technology, the emergence of various medical devices has greatly facilitated the work of medical staff. As the name implies, medical devices are instruments, equipment, utensils, in vitro diagnostic reagents and calibrators, materials, and other similar or related items directly or indirectly used on the human body, including the required computer software. The sample extraction device is a relatively common medical device, mainly used for sample extraction work;

[0003] A document with the publication number of CN219161718U discloses a sample sampling device for medical examination, including a sampling pen. The top of the sampling pen is snap-fitted with a top cover. The front side of the upper part of the sampling pen is fixedly installed with a side plate. A control switch is arranged outside the side plate. A through groove is opened on the lower side of the front part of the sampling pen. Grooves are opened on the front and rear sides of the lower part of the sampling pen. The bottom end of the sampling pen is fixedly installed with a base;

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. In the above-mentioned sample sampling device, a micro air pump and a battery are fixed in the air suction chamber at the top of the sampling pen. A sample storage tube is arranged in the through groove of the sampling pen through a lower mounting seat and an upper mounting seat. At the same time, a sampling head is arranged on the sampling pen through the base. The negative pressure generated by the micro air pump enables the sample to enter the sample storage tube through the sampling head. However, it can only sample one type of sample. When multiple types of samples need to be sampled, the sampling pen and other structures need to be cleaned and disinfected midway, which is not convenient for sampling multiple types of samples simultaneously;

[0006] 2. In the above-mentioned sample sampling device, the bottom end of the sampling pen is fixedly installed with a base, and the bottom end of the base is threadedly connected with a sampling head through a connecting column. The sampling head is used for sampling the sample. However, it lacks a structure for protecting the sampling head, resulting in the sampling head being easily damaged when the sampling pen drops.

[0007] Therefore, we provide a sample extraction device for medical examination to solve the above problems. Content of the Utility Model

[0008] The purpose of the present utility model is to provide a sample extraction device for medical testing. The suction pump in the sampling component drives two sampling cylinders to extract different samples, solving the problem that only one sample can be extracted simultaneously in the prior art.

[0018] A further setting of the utility model is that threaded pipes are welded to one ends of the sampling heads close to the sampling pipes, and the ends of the threaded pipes away from the sampling heads are threadedly connected to the inner sides of the sampling pipes.

[0019] A further setting of the utility model is that fixing plates are welded to the front and rear end faces of the sleeve and the lifting plate, grooves are formed in one sides of the fixing plates close to each other, and magnets are fixedly connected to the interiors of the grooves.

[0020] The utility model has the following beneficial effects:

[0021] 1. By arranging the sampling assembly, the utility model extracts different samples through two sampling cylinders.

This embodiment provides a sample extraction device for medical testing, including an outer shell 1 and a sampling component 2, and the sampling component 2 includes a sampling cylinder 201, a suction pump 203, a connecting tube 206, and a solenoid valve 207;

[0038] Specifically, the sampling cylinders 201 are respectively fixedly connected to the upper and lower inner sides of the outer shell 1. The front end face of the outer shell 1 is penetrated by an installation shell 202. An air suction pump 203 is fixedly connected inside the installation shell 202. An air suction pipe 204 is fixedly connected to the air inlet end of the air suction pump 203. One end of the air suction pipe 204 away from the air suction pump 203 is fixedly connected to a connecting pipe 206 through a three-way joint 205. One end of the connecting pipe 206 away from the three-way joint 205 penetrates through one end of the sampling cylinders 201 close to each other and extends to the inside of the sampling cylinders 201. An electromagnetic valve 207 is arranged on the connecting pipe 206. The sampling cylinders 201 are used to extract samples. The installation shell 202 is used to install the air suction pump 203. And due to the arrangement of the air suction pump 203, the inside of the sampling cylinders 201 is in a negative pressure state, so that the sampling cylinders 201 extract samples. The air suction pipe 204 and the connecting pipe 206 are used to connect the air suction pump 203 and the sampling cylinders 201. And the electromagnetic valve 207 is used to control the switch of the connecting pipe 206. And the connection between the air suction pipe 204 and the connecting pipe 206 is realized through the arrangement of the three-way joint 205.

[0039] Furthermore, a button 101 is arranged at the center position of the rear end face of the outer shell 1. The button 101 is electrically connected to the air suction pump 203 and the electromagnetic valve 207 through wires. Rubber pads 102 are bonded to the outer side walls of both sides of the outer shell 1. Transparent plates 103 are inlaid above and below the front and rear end faces of the outer shell 1. Liquid level scale lines 104 are engraved on the end faces of the transparent plates 103. There are two groups of buttons 101, which are used to control the power supply of the air suction pump 203 and the electromagnetic valve 207. The rubber pads 102 are convenient for medical staff to hold the outer shell 1. The transparent plates 103 and the liquid level scale lines 104 are convenient for medical staff to know the quantity of samples in the sampling cylinders 201;

[0040] Sampling pipes 201a penetrate through the mutually remote ends of the sampling cylinders 201 respectively. One end of the sampling pipes 201a extends to the inside of the sampling cylinders 201. The other ends of the sampling pipes 201a penetrate through the top and bottom of the outer shell 1 respectively and are fixedly connected to sampling heads 208. The sampling pipes 201a are used to install the sampling heads 208. And samples are extracted through the sampling heads 208;

[0041] Threaded pipes 208a are welded to one ends of the sampling heads 208 close to the sampling pipes 201a. One ends of the threaded pipes 208a away from the sampling heads 208 are threadedly connected to the inside of the sampling pipes 201a. The threaded pipes 208a realize the threaded connection between the sampling heads 208 and the sampling pipes 201a.

[0042] The operation process of this embodiment is as follows: Press one group of buttons 101, so that the suction pump 203 and one group of solenoid valves 207 are energized. At this time, under the action of the suction pump 203, a negative pressure state is presented inside one group of sampling cylinders 201. Under the influence of the negative pressure state, the external sample sequentially passes through the sampling head 208 and the sampling tube 201a and enters the inside of the sampling cylinder 201, realizing the extraction of the sample. After the sample extraction of this group of sampling cylinders 201 is completed, press another group of buttons 101 to extract other samples through another group of sampling cylinders 201. Specific Embodiment Two

[0044] Please refer to Figure 6-8 As shown, it is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but different from the previous embodiment is that: protective components 3 are also provided at the top and bottom of the housing 1, and the protective components 3 include sleeves 301, lifting plates 303, protective shells 304 and return springs 305. The protective shell 304 is driven by the lifting plate 303 and the return spring 305 to move to the outside of the sampling head 208, solving the problem that the existing sampling head 208 is not easy to be protected.

[0045] Specifically, the sleeves 301 are respectively fixedly connected to the top and bottom of the housing 1. Both sides inside the sleeves 301 are fixedly connected with sliding rods 302 along the vertical direction. The outer wall of the sliding rods 302 is slidably sleeved with lifting plates 303. The surface of the lifting plates 303 penetrates through the protective shells 304. One end of the protective shells 304 penetrates through one end of the sleeves 301 and extends to the outside of the sleeves 301. The outside of the sliding rods 302 is sleeved with return springs 305. The two ends of the return springs 305 are respectively fixedly connected to the sleeves 301 and the lifting plates 303. The sleeves 301 are provided for installing structures such as the sliding rods 302. The sliding rods 302 are provided for movably installing the lifting plates 303 inside the sleeves 301. The lifting plates 303 are provided for driving the protective shells 304 to move and protecting the sampling head 208 through the protective shells 304. At the same time, the return springs 305 are provided to drive the lifting plates 303 to automatically reset, so that the protective shells 304 are located outside the sleeves 301 when there is no external force.

[0046] Furthermore, fixing plates 301a are welded on the front and rear end faces of the sleeves 301 and the lifting plates 303. Grooves 301b are respectively opened on the sides of the fixing plates 301a close to each other. Magnets 301c are fixedly connected inside the grooves 301b. The fixing plates 301a and the grooves 301b are provided for installing the magnets 301c. The magnets 301c on the sleeves 301 and the lifting plates 303 have opposite magnetic properties. The lifting plates 303 are adsorbed through the magnets 301c, so that the protective shells 304 are located inside the sleeves 301 during the sample extraction process.

[0047] The remaining structure is the same as that of the first embodiment.

[0048] The operation process of this embodiment is as follows: When extraction work needs to be carried out, an external force is applied to the protective shell 304, so that the protective shell 304 drives the lifting plate 303 to move, making the protective shell 304 move to the inside of the sleeve 301. At this time, the magnets 301c on the sleeve 301 and the lifting plate 303 are in contact with each other, and the protective shell 304 is fixed under the attraction between the magnets 301c. Then, the sample extraction work is carried out through the outer shell 1. Finally, after the extraction is completed, an external force is applied to the lifting plate 303 to separate the magnet 301c on the lifting plate 303 from the magnet 301c on the sleeve 301. At this time, under the action of the return spring 305, the protective shell 304 moves back to the outside of the sleeve 301.
