Description

Technical Field

[0001] The utility model relates to the technical field of blood collection needles, in particular to a combined blood collection needle. Background Art

[0002] A lancet is a medical device used to collect blood samples. The needle is inserted into the patient's skin to puncture it, and then the required amount of blood is drawn or scraped through a connector for subsequent blood testing.

[0003] The needles of existing blood collection needles cannot be completely hidden after use, and there is blood residue, which increases the risk of other people coming into contact with the blood on the needle, leading to the spread of infectious diseases. At the same time, blood collection needles that are not handled in time have the risk of accidentally stabbing other people or yourself, increasing the occurrence of stabbing accidents.

[0004] The existing blood collection needle has the following disadvantages: after the existing blood collection needle is used, the needle of the blood collection needle is exposed, which may cause the needle to accidentally contact a person, causing unintentional stabbing of other people or oneself, increasing the risk of infection caused by stabbing accidents. To this end, we propose a combined blood collection needle. Utility Model Content

[0005] The main purpose of the utility model is to provide a combined blood collection needle, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A combined blood collection needle comprises a storage sleeve assembly and a lifting needle assembly, wherein the lifting needle assembly is arranged in the storage sleeve assembly;

[0008] The storage sleeve assembly comprises a sleeve, an internal threaded socket, a PP protective patch and a tear sheet.

[0009] Furthermore, the internal threaded hole is vertically penetrated and opened in the middle of the sleeve, and the PP protective patch is adhered to the bottom of the sleeve.

[0010] Furthermore, a tear sheet is provided on one side of the PP protective patch.

[0011] Furthermore, the lifting needle assembly includes a threaded column, a needle head, a handle and an elevation groove, and the threaded column is threadedly inserted in the internal threaded hole.

[0012] Furthermore, the tail end of the needle is vertically inserted into the bottom of the threaded column, the top of the threaded column away from one end of the needle is fixedly connected with a handle, and the elevation groove is arranged at the top of one side of the threaded column.

[0013] Compared with the prior art, the utility model has the following beneficial effects: through the assembly consisting of the housing assembly and the lifting needle assembly, a combined blood collection needle structure with high safety is provided for blood collection personnel, the patient's skin is punctured for blood collection by the needle at the bottom of the lifting needle assembly, and the needle at the bottom of the lifting needle assembly is protected after blood collection by the storage housing assembly, so that the needle at the bottom of the lifting needle assembly is retracted into the housing assembly to hide the needle, which can effectively reduce the exposure of the needle to the outside, improve the safety of the blood collection needle, and solve the problem that after the use of the existing blood collection needle, the needle of the blood collection needle is exposed to the outside, which may cause the needle to accidentally contact a person, causing unintentional stabbing of other people or oneself, increasing the occurrence of stabbing accidents and causing the risk of infection.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a combined blood collection needle includes a storage sleeve assembly 1 and a lifting needle assembly 2, wherein the lifting needle assembly 2 is arranged in the storage sleeve assembly 1, and the storage sleeve assembly 1 includes a sleeve 101, an internal threaded socket 102, a PP protective patch 103 and a tear sheet 104.

[0021] The internal threaded hole 102 is vertically penetrated and opened in the middle of the sleeve 101 , and the PP protective patch 103 is pasted on the bottom of the sleeve 101 .

[0022] Among them, a tear sheet 104 is provided on one side of the PP protective patch 103, and the lifting needle assembly 2 includes a threaded column 201, a needle 202, a handle 203 and a height groove 204. The threaded column 201 is threadedly inserted in the internal threaded hole 102; the bottom of the sleeve 101 is protected by the PP protective patch 103 to protect the needle 202 in an unused state to prevent external foreign matter from entering.

[0023] The tail end of the needle 202 is vertically inserted into the bottom of the threaded column 201 , the top of the threaded column 201 away from the needle 202 is fixedly connected with a handle 203 , and the elevation groove 204 is set at the top of one side of the threaded column 201 .

[0024] It should be noted that the utility model is a combined blood collection needle. When working, the blood collection personnel tear off the PP protective patch 103 from the bottom of the sleeve 101 through the tear-off piece 104, and then rotate the handle 203 to move the threaded column 201 carrying the needle 202 down in the inner thread of the sleeve 101 until the needle 202 is exposed at the bottom of the sleeve 101. The blood collection personnel can use the needle 202 to puncture the patient for blood collection. After the blood collection is completed, the blood collection personnel rotate the handle 203 again to retract the threaded column 201 carrying the needle 202 into the sleeve 101, so that the needle 202 is hidden. Because the elevation groove 204 is set at the top of one side of the threaded column 201, after the elevation groove 204 is exposed from the top of the sleeve 101, it means that the needle 202 has been completely stored, so that the needle 202 can be protected, thereby greatly reducing the risk of the needle 202 contacting the outside and being stabbed, and effectively improving the safety of the use of the blood collection needle.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
